After watching all this, I went with a solid quartz shower pan and extra large format (48" sq.) wall tiles. The goal being to eliminate grout lines on floor and minimize grout lines on walls.
As a Schlüter-trained installer, I have to say that they have truly worked out a bunch of issues for you. If you have ANY questions they are very happy to help you over the phone. Count me as SOLD on this stuff.
Unmodified is your traditional mortar made mostly of Portland cement. Modified will have latex additives. They dry and cure differently. This product is water proof so modified mortars won't be able to dry out properly. Works great with Unmodified mortar though.
We installed a 60” shower last spring. The large edge boards had to be cut down to allow the elderly resident to easily step into the shower. We adjusted the shower curtain rod down to ensure the curtain stayed inside the edge. Everything else went as per instructions.
@@normferguson2769 We are planning to replace our bathtub with a shower in the next year or so. Want something that will work into old age. I thought that board looked a little high. Especially of someone is using a walker to get in and out. Glad to know you can cut it down if we go with this.
@@dawnelder9046 if you get the right professional, they should be able (assuming it’s a main-level plywood subfloor) to cut into the floor joists slightly for the proper slope, and do a walk in shower with no curb. So, Just Vet Your Contractor!! That’s more important then the quality of product you use!! A professional can make the cheapest product work. A bad contractor doesn’t care you spent $80 on every tile, and will waste, cut corners, and leave you with a bad product and $10,000 poorer.
Water can leak at the transition piece going from the wall to the floor. It would be better to install the transition piece before the wall so it is overlapped from the top. Like doing shingles you want to do all u can to keep water on top. You would not install flashing on top of a shingle because it can leak even if sealant was applied. So why would you take the chance here. Have experienced leaks caused by doing this in this application already. On this video during water test that the thunder is already wicking the water. This is what causes water leaks later after tile install. Best solution I have found is to use a water proofing method over all joints prior to tile installation
Floating a mud pan is the way to go for a nicer end & Custom Homes. Yet for the track homes and banging them out faster, I guess the Schluter pan system is a step up from a cheesy fiberglass shower pan...

@@mandatethis8024 Yet a true tradesman floats his pans for strength, durability & quality. None of that Lego-Land pan crap in my customer's homes... ( X_x)
I'm all framed in, I have everything but the mud and tile. Need a plumber now. I'm doing PEX. I need to get this done. I have to tear the 2nd bathroom apart now.
Why do people still torture themselves with these multi-step jigsaw puzzles? I have used several tile-ready custom fiberglass pans and wall panels. Whole thing goes in in a couple hours, and far fewer potential failure points. Kerdi seems laborious and archaic in comparison.
Shouter works as well as any other backer board, only it is extremely costly. One of the reasons for the high cost is their “multiple level distribution system”. By the time the end user buys the product it has been transferred to multiply layers of distribution ..... eCh taking a cut.
@@billblendick9780this is for homeowner Diy that can’t build a shower pan and surround the traditional way, I’m all about new things, but one small mistake in thin setting down the sheet materials and the entire shower is compromised, not to mention lots of styrofoam? I’ll take a poured solid cement curb and pan any day and for 1/4 of the cost
I have one of these and it is made out of foam..when it is laid down how does the foam not break to a persons weight ...and the foam curb looks like if some put any type of weight on it would break it I can only imaging a kid stepping on the curb
Weird that they have you doing the wall first! As someone who has done a lot of roofing and almost every other home exterior, and for the past 15 years flooring and showers exclusively, I have to say that I always work from bottom up when waterproofing, meaning that I do the pan waterproofing then put the wall waterproofing on top of that, an would advise everyone to do the same. Never trust a joint lapped the wrong way to be water tight just because it is sealed, I don't care how much the overlap is.
I’m of the same thought process… it does say that alternative methods may be used as long as the suggested installation method of the membrane is used…. Meaning v notch trowel etc etc…
why is the long corners schluter put on prior to the wall? Will not the water go behind the tile seeping behind the bottom corner put on last. I have done this several times with this system and I still always put down in this order. Floor, corners and then the walls so there is no "natural drainage" down behind something. Or is there still a chance of capillary action ? I would like some feedback on this
Hi Nick! When KERDI is installed with a 2" overlap, water will not be able to penetrate and cause any issues, regardless of the order in which the KERDI and KERDI-BAND are applied, whether "shingled" or not. Hope this helps!
Hi there! Yes, you can shorten each side of the shower tray. First, place your shower tray so it's aligned with the drain. To keep the perimeter height even on all sides, you will need first to cut 5" off both sides of the tray. Then, trim off and re-install the 1'' edge on both sides of the tray.
I would like to see more screws holding the drywall to the suds. I don't get why someone would use drywall in the first place though. The gypsum will crumble if it gets wet.
Not to worry; drywall can be used because KERDI is a waterproofing membrane and will therefore not allow any water to penetrate and damage the drywall. We generally install drywall screws every 12" o.c., which is standard.
Schluter-Systems North America as a plumber things can and will go wrong. I've seen it. This is not a perfect world and I am not necessarily asserting that the Kerdi will fail. Other issues from behind the wall can cause water damage too. I am just saying it is an unwise practice if trying to save money. Plus depending on tile selection there will be a lot of weight hanging from those screws. Ordinary drywall screws are not known for their shear strength.
@@schlutersystems1 I will say this is an amazing product but it is scary what is being recommended to non-professionals who are probably doing this for their first time and don't know better. Some old time inspectors I know would not approve this despite your claims, and I don't blame them either.
@@AmosMosesJr We had this done in our walk in shower 11 years ago. Huge shower tiled to the ceiling. The shower had standard drywall screwed to the studs. No glue. We had zero issues. If the product is properly installed, you will not have an issue. If you are using cement board in case you have water leaking through your waterproofing, you have much bigger issues, like mold in the wall cavity.
Was going to post the same thing. Makes way more sense to me to have the wall overlap the floor pan to further ensure water doesn't get back behind the pan.
You don’t want your wall materials to be exposed to water inundation, even cement board, that’s why we put the walls on after rhino liner and dry pack , that way the water seeps thru the dry pack down to the liner and does not inundate the wall boards
I’ve installed everything and planning to do a water test tomorrow night but I just can’t understand one step and how it creates a waterproof barrier. When doing the shower pan I put in each of the corners. I’ve cut the Kerri band to put between but I don’t understand how it is waterproof without overlapping. Looks like there is a small gap between the corners and the band in your video. Is this correct? Aren’t those areas where water can travel? Do I need to overlap it or use the Kerdi caulk? There is thin set but that’s not waterproof.
Hi Brian, all of the connections should have a minimum 2" overlap of Kerdi or Kerdi-Band. If you would like to talk through this installation please give our team a call at US:800-472-4588 or CA: 800-667-8746 they would be more than happy to discuss the details with you.
Hi there! Any dry wall listed in the Solid Backing Materials section of the Shower Installation Handbook detail, meeting the proper ASTM number, is fine. It does not have to be a particular color.
The Schluter shower kit has made my first bathroom renovation incredibly easy - especially with videos like this. One step I’m unsure of is how to securely install a fixed glass shower screen on the curb since anchoring with screws will not work. Can Kerdi fix be applied to the screen mounting bracket on top of the tile or should I apply to the bare curb and then tile around? Is Kerdi fix supposed to be used in this way? Any help is much appreciated!
Hi Henry! So happy to hear that your shower installation has been a success! For this question, could you please contact our Customer Service team as there may be some variables to discuss: US 800-472-4588 CA 800-667-8746 Thanks!
So, is it fair to say that installing the bottom corner strip onto the wall and tray, and then flash over the strip with the wall membrane a "belt and suspenders" method? Why not make it the standard installation sequence? Or just extend the wall membrane minimum 2" (6" for belt/suspenders) onto the tray...?
I saw in another KERDI video that he was screwing the KERDI board directly to the wall studs. This video shows covering wallboard with KIRDI membrane. What are the pros and cons to this? I would think if you are totally renovating a tub/or shower you would be down to the studs anyway.
Hi there! There are pros to each option; it is a personal choice. If you are directly on the studs, the KERDI-BOARD will save you a lot of time. If you already have gypsum boards on your wall and they are in good shape, then we would suggest keeping them up and using the KERDI membrane over them. If you would like to discuss your project in more detail, I would recommend giving a call to our product support team; they will be able to get into the specifics of your project with you. You can reach them at 888-472-4588 (US) or 800-667-8746 (CA).
Wouldn't it be better to install the floor pan first, and then the wall sheets with a 2" overlap on the floors, so any water getting behind tile would drain down and out over the overlap, rather than relying on the band joint? Or better yet, install the floor flush to the studs/bottom plate, then drywall, then Schluter wall sheets? Then do the corners, but none of the wall to floor banding? Would this be allowable if I choose to do it that way?
Hi there ! There is no rules on what to install first as long as there is always a minimum overlap of 2'' of the Kerdi membrane. The Kerdi corners are a necessity thought as the band or overlapping won't waterproof the corners to 100%. Hope that helps
Why use a butt-seam at 5:30 when you could just overlap the two full sheets of Kerdi-membrane like you did on the other wall? Are you just demonstrating the use of the band if for some reason it's impossible to just easily/simply overlap the full sheets upon one another and skip the whole need for the kerdi-band process?
Hi there, yes, we are just showing the two options in this video. Since the KERDI-BAND is thinner than KERDI, the butt-joint method might be preferred when installing smaller tiles, such as mosaics, because there will be a little less build-up. Hope that helps!
Laboratory testing and field experience over decades has proven that thin-set seams with the KERDI membrane provide effective, reliable waterproofing for tiled showers. And we stand behind that - when installed in accordance to our Shower System Installation Handbook, your installation is fully covered by our comprehensive warranty. Here's a link to the handbook: sccpublic.s3-external-1.amazonaws.com/sys-master/images/h7e/h96/9078305357854/Shower%20System%20Installation%20Handbook.pdf
Hi there! Close, but not quite. 🙂 We are saying that all waterproofing connections with KERDI, KERDI-BAND, KERECK corners, and/or valve seals need a 2" overlap, however, the corners are longer than 2", so the KERDI-BAND can be brought back a little in that area so the strips don't overlap each other. This will still allow for the required 2" overlap. Hope that clears it up!
Question regarding the 'fairly fluid' thinset used along the Kerdi-band. Do we follow the same instruction as for the tile or we add a small additionnel portion of water at the beginning of the mixing?
Hi André! The thin-set used to install the tiles will be a little thicker than the thin-set used to install the KERDI-BAND. The different mixing ratios for installing Schluter® membranes vs. tiles can be found on the back of our thin-set bags or in our thin-set data sheets which we’ve attached here as a reference: sccpublic.s3-external-1.amazonaws.com/sys-master/images/h5e/ha8/8949341814814/ALL-SET%20Thin-set%20Data%20Sheet.pdf Hope this helps!
Hi there! Yes. Follow the applicable Shower handbook detail and discuss trowel size with the tile manufacturer and follow the tips in the following video to make sure you get full coverage. ua-cam.com/video/AaP1uA6FIQE/v-deo.htmlsi=Fnf5abiW6LBis-4y . Hope that helps!
You can seal all seams and joints after installing the tray. This excerpt is from our handbook: Seal inside corners by abutting adjacent sheets and installing KERDI-BAND with Schluter SET®, ALL-SET®, FAST-SET®, or unmodified thin-set mortar, centered over the joint.

What's the reasoning for installing drain first with no access...I've installed many with no access AFTER pan was installed...just curious of that thought process
Hi there! The main reason for this is if there are different contractors on a project and the plumber comes through first and installs the drain flange. Then the tile installer would come after to install the tray and the rest of the shower component. Plumbers don't usually work with thin set, they won't install the shower tray. Hope that helps!
What is the process in this situation where the end of the membrane meets the drywall going out of the shower? Looks like just a tile corner all the way down. Is there anything specific to do there?
Hi James! The profile leg can be installed just passed the KERDI membrane so the tile has an even transition and the KERDI is not seen under the profile from the outside.
I am using the sloped shower pan, but it needed to be trimmed back to fit where my existing drain was. What do you recommend using to slope down into the shower pan?

The "no-access" video has disappeared. Has it been replaced? And it looks to me like you can cement the PVC _and_ install the drain during the normal tray install rather than before the tray. Is there a specific reason to install the drain before the tray if I don't have access to the plumbing from below? I'm about to do my install but I don't want to get to the drain install and go "Ohhhh, THAT is why they said to install before...!"
Hi Scott, you can install the drain any time. That video is primarily for those who have different trades coming in to do separate parts of the shower install at different times. Here is the No Access video just in case: ua-cam.com/video/dw5VJclorBY/v-deo.html Hope that helps!
What is the difference between the but seem and the 2in over lap. I don’t understand why not just do the 2 in overlap like you did where the sheets meet.
Hi there, Either way is fine. It generally just depends on user preference. Some like to overlap the KERDI as the go, whereas others prefer to butt join the KERDI and then cover with the KERDI-BAND. One practical reason for using the KERDI-BAND in some instances is when a small mosaic is being installed over the seam. Since the KERDI-BAND is thinner than KERDI, the build-up at the seam would be slightly less. Hope this helps!
Hi Melvin! Good question! The thin set mortar is not waterproof. If the water penetrates the grout and get's to the thin set it will reach the KERDI membrane and go no further. And then eventually, it just evaporates back out through the grout lines. No worries!
Hi! Yes you could install the shower tray first. As long as the 2'' overlap is achieved at every seams, with KERDI or KERDI-BAND, the order of wall and floor installation doesn't matter. Hope that helps!
Hi there! It would be best to give our Customer Support a call directly to discuss. They will have a few questions for you about your specific project, but can certainly guide you from there! Hope this helps, and best of luck with your project!! 1-800-472-4588 (USA) or 1-800-667-8746 (CAN).
Hi there. Since KERDI membrane is installed over the solid backing down to the subfloor and the provided shower tray is waterproof, the seams of the outside perimeter and corner seams of the shower tray must be sealed to create a fully waterproof and vapor tight enclosure. By installing the KERDI-BAND and KERDI-KERECK inside corners over the pre-sloped shower tray, these components prevent moisture disseminating below the top of the tray; therefore, installing the KERDI-BAND and KERDI-KERECK corners underneath the tray is not necessary as moisture will not travel to the substrate. Hope that helps!
I'm no genius, however wouldn't it make sense to keedi band the tray to wall joint first, then wrap your walls with membrane overlapping the keedi band at the bottom.....since water sheds down ?
Hi AJ, it can be done either way. The 2" overlap of the KERDI to KERDI-BAND will not allow water to penetrate the seem regardless if it is "shingled" or not. Hope this helps!
You can use Kerdi on the walls for sure! We do have the Kerdi-Tubkit that includes everything but the shower tray and drain: www.schluter.com/schluter-us/en_US/Shower-System/Shower-%26-Tub-Kits/Schluter%C2%AE-KERDI-TUBKIT/p/KERDI_TUBKIT?facets=false

Hi Steven, the flange outlet is connected to the drain pipe with either PVC or ABS glue, depending on which pipe material and corresponding drain you are using. The reason we don't show that in this video is because there is access below to connect the drain later. Here is different video which shows you the gluing process for a no access installation: ua-cam.com/video/u-ZILYISeX8/v-deo.html Hope this helps!
Good question! The curb itself is not sloped. When you are setting tile on the curb, the tile must be sloped towards the shower drain using a little extra thin-set under the tile on the further edge from the drain. Hope this helps!
I have a travertine shower with a failed shower pan. Rather than replacing all of the tile work in the entire shower, can I demo and replace the pan, remove two feet of the old travertine and shingle the new Kerdi a few inches above and behind the old shower wall base? Would this create a wicking problem over time? This would allow me to keep most of the old tile work. Thank you!

System looks brilliant. My gripe is though the shower proofing is paper and your taking metal trowels to it to flatten/thin set tiles. Aren't you worried you'll scratch the membrane?
Hi Andrew, KERDI is a sheet-applied polyethylene waterproofing membrane designed for the application of tile. Decades of projects behind it, so no worries of a trowel damaging the membrane when installed correctly. Thanks!
Hi there! Apologies for the delay... The options for sloping a tiled shower floor to the drain are a KERDI-SHOWER-TRAY or a Portland cement mortar bed. The sloped mortar bed would need to be installed prior to the KERDI membrane so it wall be waterproofed on top and the water would slope to the drain and not saturate the mortar bed. The KERDI on top of the mortar bed would also continue up the walls in accordance with our Shower Systems Installation Handbook to create a completely waterproofed and properly sloped installation from the shower head to the drain. Neither grout or thin-set would be appropriate materials for creating a slope for the shower floor. Here's a link the handbook: sccpublic.s3-external-1.amazonaws.com/sys-master/images/hd1/h93/9007208038430/Shower%20System%20Installation%20Handbook.pdf
I have a odd shaped wLk in shower, one valley is at a 45 degree angle. For the part of the shower are that has the angle wall, could I use a shower pan, say 48 x 48, trim to size to fit, and cut off one corner of the pan to fit the angled wall? Then for the flood where I walk into the shower, could I Juilliard the floor height up to the shower pan height by using plywood Then cement boars, and cover the cement board with Kerdi and seal the Kerri to the shower pan? Do that instead of building floor up with mortar?
Good question! The waterproofing Kerdi membrane can be applied to any approved backer board. You can see all of the requirements here: sccpublic.s3-external-1.amazonaws.com/sys-master/images/he2/h48/8984381980702/Shower%20System%20Installation%20Handbook.pdf

Why not overlap and join the seams together with kerdi band in a process that water never runs directly into a seam? For example..first membrane the shower pan. Then apply kerdi band and corners to the pan and wall board. Then membrane the wall over the kerdi band so the seams are never in direct contact with the direction of water flow. The schluter method is putting too much faith in the technology of how the kerdi band adheres to the membrane through the thinset during the curing process. This process could result in failure given the fact that thinset isnt waterproof and its possible theres not a 100% connection of the overlapping membranes. Installing it in the overlap method I stated in beginning of this post takes out any possibility of water flowing directly into any seam.
U are absolutely 💯 correct and Idk y shluter doesn't not apply the proper water shedding techniques and they need some kind of closed cell product to water proof 100% or it will leak after a few years this shit is crazy stupid and only a small amount of us have enough sense to see this.
so your saying do the shower pan first, connecting all the corners and membranes to the board then do the walls over that so the wall membrane is the “front” piece of membrane showing and not the corners? sorry just having trouble envisioning it. the way you stated makes more sense, no seam contact with water. just wanna clarify.
@@nickroussain317 yes no direct seam contact. I call it the shingle method. Shingles overlap so water sheds over the shingles. Same principle here. Obviously the technology guarantees full waterproof either way but for me as the installer I like having extra piece of mind knowing that any water moving towards the drain will not run directly into a seam but rather flow over the seams since they overlap from the top down like shingles. Its still the same technology so the manufacturer should still warranty the product as long as youre still using the mortar they recommend and doing the manufacter recommended overlap which is usually like 2"
Will this membrane accept heavy tiles. i plan to use durock for my walls for that purpose. is durock an overkill since the video depicts the use of regular drywell. Thanks
Hi Carlos, yes, KERDI will hold heavy tiles. Regular drywall is all that is required beneath KERDI, however cement backer board and other solid backing materials (listed in our Shower Installation Handbook) are also acceptable. Here's our Shower Installation Handbook for reference: sccpublic.s3-external-1.amazonaws.com/sys-master/images/hd1/h93/9007208038430/Shower%20System%20Installation%20Handbook.pdf
@Pat Capo durarock?banding? Do you mean drywall mud and tape? Did you prime and seal as well as do a coat of acrylic paint,or better yet mold resistant drywall,mesh tape,and coat with rubber paint before the kerdi system? Edit: oh did you mean cement backer and mesh tape? I like to give that the same treatment as mold resistant drywall. I know you've probably finished your project by now,but ive made just about every mistake you can is all.

Hi Pam, we don't have any specific information as to whether those products are safe for marine life. However, our Safety Data Sheets are all available on our website. You can find them on the product page under "Downloads". They may be helpful. Also, since all of our shower components will be encapsulated within the tile assembly, you may want to focus on the suitability of the tile and grout that you'll be using in your application, as they would be the exposed products. Hope this helps!
Hi there, since KERDI-BAND is half the thickness of KERDI, covering a butt joint with KERDI-BAND will a be little less build-up than a lap seam, which may be helpful when installing small mosaics. Otherwise, either method may be used and it's just a matter of preference. Hope this helps!
I have installed my walls (Kerdi board) but haven’t taped yet. I now think I’d feel better if I trim the wall bottoms to accept the pan after thin set, cut the pan to fit stud to stud, remove the pan and tape the walls, install the pan, Kerdi fix where the walls meet the pan and curbs, tape the pan and curbs (my kit uses membrane on the pan and curbs). Would you talk me out of this? If yes, why?
considering giving this a shot on our own. I've seen the system on a lot of home improvement shows. Question is, how does one install glass doors/panels into the foam curbs?
Hi there! You can use the DECO-SG to install the glass on top of the curb or you can use KERDI-FIX and anchors with other framing. Please contact Customer Service for anchor installation instructions. Hope this helps!
In 20 years never anchored a door set into a shower curb or tub edge, that is ripe for leaks. you lay down a double bead of silicone for pre-fab units. Custom panels depends on the install type but are usually similar. Those yelling about hot mop and vinyl liners on here are just afraid of the inevitable. Currently using this system to replace a hot mop/mortor bed custom job that apparently leaked for 20+ years...had to replace 90% of the subfloor in the bathroom and a couple floor joists. This system is so much easier and lighter, never had a leak in all the times I've used it.

I have access to drain, in fact it sits above my subfloor and Kerdi shower pan. Do I cut that drainpipe two inches below the bottom or two inches below the top of the subfloor? Does the Kerdi PVC drain assembly then get glued to my drain pipe or does it just fit into place? Thanks.

I installed my shower, but missed the part where you discuss “memory” in the corner pieces - I could not get them smooth due to the shipping fold - blocking them to flatten them out created a couple of other dimples (oops). I guess I just cut those flaws out and put a Kerdi-band patch over the flaws?
Hi there! Yes, you can definitely cut out any imperfections in the KERDI and patch over the flaws provided at least 2 inches are achieved at these areas. Hope this helps!
@@surfingweb7176 I actually tried futzing about with it until I pulled it out - washed off and heated it with hot water, dried it off, tried again. Eventually blocked it (fail - mentioned above). Finally just cut a long piece of band and put a patch over the pieces flattened by slicing off lumps, taking care to 2” overlap. Result was nice but not so much mid-way. Yes the hair dryer (or heat gun) would have greatly improved. Now I know. Thx.
Hi there! KERDI-BAND is only necessary at the DITRA to curb connection when a waterproof floor adjacent to the shower is desired. Otherwise it's optional. Hope this helps!
Hi Andre! Yes any leveling of the floor must be done prior to the installation of the shower tray. Otherwise it will affect the slope of the shower floor. Hope that helps!
Hi Denis, yes, you can. There is a complete list of approved Solid Backing Materials on each detail page in the Schluter Shower System Installation Handbook. Hope this helps!
Hi Ernst, all penetrations through the KERDI-DS membrane (e.g., steam inlet, lights, etc.) must be treated with KERDI-SEAL-PS seals, room temperature vulcanizing sealant, or other suitable sealant.
Can I use modified thin set mortar for the schluter orange Waterproofer on Sheetrock? And can I use modified thin set mortar on foam shower tray on concrete?
I don't understand why all the parts that get applied in an order that seems to be backwards. If water were to get under any part it will stay under forever. you example starts from the top down basically. Why don't you start at the drain and work your way up installed the pieces so the higher pieces fall on top of the next going down.
Hi Dave! The sequence of membrane installation can vary provided that a minimum 2" (50 mm) overlap is maintained at all joints and proper connection to the KERDI-DRAIN is established. Also, top-over-bottom or shingle laps of the membrane are not required. So, It does not matter which layer of KERDI goes down first in order for a waterproof seal to be made.

Hi there! My wife would like me to frame a bench into the rough shower. Any problems with a 48x60 shower that uses a 48x48 shower pan and has a 48x12 bench on one side? I'd be using the 48x48 Kerdi shower pan and then just use the membrane to waterproof the bench section and up the walls.
Sure! This video gives you the steps for installing the bench with the tray and waterproofing the connections: www.schluter.com/schluter-us/en_US/video_shower-systems/video/Jn58yNMqvSU/playlist/PLEFjeySFJM-Bqg39YC-9A5d9iLu547R0j
If installing 2 curbs (90 degrees); how do you waterproof the “top” of the inside corner? They dont make a patch for that. Turn a corner inside out and cut the part that would now lay on the top? Also need to add a small strip of kerdi band to top of that?
You'll need an outside corner and some KERDI-BAND to waterproof that area. This video explains how to waterproof the whole 90 degree corner of the curb, inside and out, in detail: ua-cam.com/video/IbPEFlN94nU/v-deo.html
Do you have to use the supplied curb? Just wondering if it's possible to have a curbless shower and completely waterproof the floor still using this kit.
Hi there! We have trays designed for curbless applications and yes, the surrounding floor would need to be waterproofed too (Ditra for the win!). You can have a look at our Curbless Shower section on our website here: www.schluter.com/schluter-us/en_US/curbless-showers We also have a video on creating a curbless shower! ua-cam.com/video/OexDcwZKvkc/v-deo.html Hope this helps!

Just a question. If modified thinset is a food source for mold, doesn’t that mean every shower that has ever been installed without modified thinset has a mold problem? That is basically what Schluter is saying but I find that hard to believe especially because I have never once in 25 years went back to a home because there is a mold problem. Overall, their shower system is pretty darn good. There are just way too many steps, seams every where, and their fabric is too thick and doesn’t crimp. I had a rep install a kit in our showroom and I had to tile it. I had to shave the back of the tile to get the cuts around the curb installed. Multiple layers of fabric = thicker bumps to tile over period.
Give this man a stepladder
After watching all this, I went with a solid quartz shower pan and extra large format (48" sq.) wall tiles. The goal being to eliminate grout lines on floor and minimize grout lines on walls.
As a Schlüter-trained installer, I have to say that they have truly worked out a bunch of issues for you. If you have ANY questions they are very happy to help you over the phone. Count me as SOLD on this stuff.
Thanks for your support!

Unmodified is your traditional mortar made mostly of Portland cement. Modified will have latex additives. They dry and cure differently. This product is water proof so modified mortars won't be able to dry out properly. Works great with Unmodified mortar though.
Just got my kit for a 42" x 70" custom shower. Cut the pan to size in minutes! Was not looking forward to mud, vinyl and mud again. Great pan so far.
Glad to hear!
@@schlutersystems1 can a kit be ordered for a 42x60 shower? all i see is 48x48 shower bases?
We installed a 60” shower last spring. The large edge boards had to be cut down to allow the elderly resident to easily step into the shower. We adjusted the shower curtain rod down to ensure the curtain stayed inside the edge. Everything else went as per instructions.

@@dawnelder9046 if you get the right professional, they should be able (assuming it’s a main-level plywood subfloor) to cut into the floor joists slightly for the proper slope, and do a walk in shower with no curb. So, Just Vet Your Contractor!! That’s more important then the quality of product you use!! A professional can make the cheapest product work. A bad contractor doesn’t care you spent $80 on every tile, and will waste, cut corners, and leave you with a bad product and $10,000 poorer.
Water can leak at the transition piece going from the wall to the floor. It would be better to install the transition piece before the wall so it is overlapped from the top. Like doing shingles you want to do all u can to keep water on top. You would not install flashing on top of a shingle because it can leak even if sealant was applied. So why would you take the chance here. Have experienced leaks caused by doing this in this application already. On this video during water test that the thunder is already wicking the water. This is what causes water leaks later after tile install. Best solution I have found is to use a water proofing method over all joints prior to tile installation
I was thinking the same exact thing

I'm all framed in, I have everything but the mud and tile. Need a plumber now. I'm doing PEX. I need to get this done. I have to tear the 2nd bathroom apart now.
Why do people still torture themselves with these multi-step jigsaw puzzles? I have used several tile-ready custom fiberglass pans and wall panels. Whole thing goes in in a couple hours, and far fewer potential failure points. Kerdi seems laborious and archaic in comparison.
Shouter works as well as any other backer board, only it is extremely costly. One of the reasons for the high cost is their “multiple level distribution system”. By the time the end user buys the product it has been transferred to multiply layers of distribution ..... eCh taking a cut.
What else do you recommend?

I have one of these and it is made out of foam..when it is laid down how does the foam not break to a persons weight ...and the foam curb looks like if some put any type of weight on it would break it I can only imaging a kid stepping on the curb
Weird that they have you doing the wall first! As someone who has done a lot of roofing and almost every other home exterior, and for the past 15 years flooring and showers exclusively, I have to say that I always work from bottom up when waterproofing, meaning that I do the pan waterproofing then put the wall waterproofing on top of that, an would advise everyone to do the same. Never trust a joint lapped the wrong way to be water tight just because it is sealed, I don't care how much the overlap is.
I’m of the same thought process… it does say that alternative methods may be used as long as the suggested installation method of the membrane is used…. Meaning v notch trowel etc etc…
First time I seen this video exactly my thoughts. Do floor first then continue with walls and overlap water proof membrane.
this is brilliant product for DIYers - can't wait to use this on my first bath remo
let us know how it goes!
why is the long corners schluter put on prior to the wall? Will not the water go behind the tile seeping behind the bottom corner put on last. I have done this several times with this system and I still always put down in this order. Floor, corners and then the walls so there is no "natural drainage" down behind something. Or is there still a chance of capillary action ? I would like some feedback on this
Hi Nick! When KERDI is installed with a 2" overlap, water will not be able to penetrate and cause any issues, regardless of the order in which the KERDI and KERDI-BAND are applied, whether "shingled" or not. Hope this helps!
The number of times the word “Kerdi” is said sounds like a brainwashing session.
it is
@@iam2dolla ] p⁹
You should have the installer put 2x4 behind the curb when first installed to help keep it in place with a couple screws
it will set in about 1 min no need to do that
Thought about doing this. Couldn't see it hurting but probably not needed
Can you cut down the size of the shower pan say I have a 60x38 and I want a 60x30. Can I cut 4 inches off each side?
Hi there! Yes, you can shorten each side of the shower tray. First, place your shower tray so it's aligned with the drain. To keep the perimeter height even on all sides, you will need first to cut 5" off both sides of the tray. Then, trim off and re-install the 1'' edge on both sides of the tray.
Why would I have to cut off 5 inches off each side and add 1 inch back?
Exactly!
Why not cut 4" off each side and be done?
Also my walls are 100% waterproof hardiebacker. Do I still put up the kerdi membrane over that with allset?
I would like to see more screws holding the drywall to the suds. I don't get why someone would use drywall in the first place though. The gypsum will crumble if it gets wet.
Because if the a schluter is installed properly, the drywall won’t get wet. I’d like to think this drywall is glued on this application but who knows
Not to worry; drywall can be used because KERDI is a waterproofing membrane and will therefore not allow any water to penetrate and damage the drywall.
We generally install drywall screws every 12" o.c., which is standard.
Schluter-Systems North America as a plumber things can and will go wrong. I've seen it. This is not a perfect world and I am not necessarily asserting that the Kerdi will fail. Other issues from behind the wall can cause water damage too. I am just saying it is an unwise practice if trying to save money. Plus depending on tile selection there will be a lot of weight hanging from those screws. Ordinary drywall screws are not known for their shear strength.
@@schlutersystems1 I will say this is an amazing product but it is scary what is being recommended to non-professionals who are probably doing this for their first time and don't know better. Some old time inspectors I know would not approve this despite your claims, and I don't blame them either.
@@AmosMosesJr We had this done in our walk in shower 11 years ago. Huge shower tiled to the ceiling. The shower had standard drywall screwed to the studs. No glue. We had zero issues. If the product is properly installed, you will not have an issue. If you are using cement board in case you have water leaking through your waterproofing, you have much bigger issues, like mold in the wall cavity.
Would it not make more sense to install the wall membranes last?
Was going to post the same thing. Makes way more sense to me to have the wall overlap the floor pan to further ensure water doesn't get back behind the pan.
@@The_UA-cam_Critic I was thinking the same thing as well. Think about it like a shingled roof.
That is what the band is for
You don’t want your wall materials to be exposed to water inundation, even cement board, that’s why we put the walls on after rhino liner and dry pack , that way the water seeps thru the dry pack down to the liner and does not inundate the wall boards
With the kerdi band and inside corners installed as directed it makes no difference
Would it not be better to start from bottom to top, so that overlapping will always downwards?
HI! It doesn't matter; it's really a preference. As long as you have a 2" overlap, that works for us. Hope that helps!
Ever noticed that most high Quality products and Systems are made in Germany?
No
I’ve installed everything and planning to do a water test tomorrow night but I just can’t understand one step and how it creates a waterproof barrier. When doing the shower pan I put in each of the corners. I’ve cut the Kerri band to put between but I don’t understand how it is waterproof without overlapping. Looks like there is a small gap between the corners and the band in your video. Is this correct? Aren’t those areas where water can travel? Do I need to overlap it or use the Kerdi caulk? There is thin set but that’s not waterproof.

Shouldn't u use green or purple water resistant dry wall??
Hi there! Any dry wall listed in the Solid Backing Materials section of the Shower Installation Handbook detail, meeting the proper ASTM number, is fine. It does not have to be a particular color.
The Schluter shower kit has made my first bathroom renovation incredibly easy - especially with videos like this. One step I’m unsure of is how to securely install a fixed glass shower screen on the curb since anchoring with screws will not work. Can Kerdi fix be applied to the screen mounting bracket on top of the tile or should I apply to the bare curb and then tile around? Is Kerdi fix supposed to be used in this way? Any help is much appreciated!

So, is it fair to say that installing the bottom corner strip onto the wall and tray, and then flash over the strip with the wall membrane a "belt and suspenders" method? Why not make it the standard installation sequence? Or just extend the wall membrane minimum 2" (6" for belt/suspenders) onto the tray...?
I need the guy in this video to come do mine for me...
I saw in another KERDI video that he was screwing the KERDI board directly to the wall studs. This video shows covering wallboard with KIRDI membrane. What are the pros and cons to this? I would think if you are totally renovating a tub/or shower you would be down to the studs anyway.
Hi there! There are pros to each option; it is a personal choice. If you are directly on the studs, the KERDI-BOARD will save you a lot of time. If you already have gypsum boards on your wall and they are in good shape, then we would suggest keeping them up and using the KERDI membrane over them. If you would like to discuss your project in more detail, I would recommend giving a call to our product support team; they will be able to get into the specifics of your project with you. You can reach them at 888-472-4588 (US) or 800-667-8746 (CA).
The curb looks like it flexes and would cause cracking issues if stepped on
Wouldn't it be better to install the floor pan first, and then the wall sheets with a 2" overlap on the floors, so any water getting behind tile would drain down and out over the overlap, rather than relying on the band joint? Or better yet, install the floor flush to the studs/bottom plate, then drywall, then Schluter wall sheets? Then do the corners, but none of the wall to floor banding? Would this be allowable if I choose to do it that way?
Hi there ! There is no rules on what to install first as long as there is always a minimum overlap of 2'' of the Kerdi membrane. The Kerdi corners are a necessity thought as the band or overlapping won't waterproof the corners to 100%. Hope that helps
awesome job that shower is bomb proof
Why use a butt-seam at 5:30 when you could just overlap the two full sheets of Kerdi-membrane like you did on the other wall? Are you just demonstrating the use of the band if for some reason it's impossible to just easily/simply overlap the full sheets upon one another and skip the whole need for the kerdi-band process?
Hi there, yes, we are just showing the two options in this video. Since the KERDI-BAND is thinner than KERDI, the butt-joint method might be preferred when installing smaller tiles, such as mosaics, because there will be a little less build-up. Hope that helps!
Where the drywall is beveled, you just level it under the membrane with extra thinset?
Any minor differences can be addressed when setting the tile. :)
@@schlutersystems1 Thank you for the info
Thin set mortar is not waterproof. How can you then make waterproof seals when you attach the kerdi band using thin set mortar?
Laboratory testing and field experience over decades has proven that thin-set seams with the KERDI membrane provide effective, reliable waterproofing for tiled showers. And we stand behind that - when installed in accordance to our Shower System Installation Handbook, your installation is fully covered by our comprehensive warranty.
Here's a link to the handbook: sccpublic.s3-external-1.amazonaws.com/sys-master/images/h7e/h96/9078305357854/Shower%20System%20Installation%20Handbook.pdf
You’re saying a 2 inch overlap at all transitions except the Kerdi band can be flush against the inside corners correct??
Hi there! Close, but not quite. 🙂 We are saying that all waterproofing connections with KERDI, KERDI-BAND, KERECK corners, and/or valve seals need a 2" overlap, however, the corners are longer than 2", so the KERDI-BAND can be brought back a little in that area so the strips don't overlap each other. This will still allow for the required 2" overlap. Hope that clears it up!
Question regarding the 'fairly fluid' thinset used along the Kerdi-band. Do we follow the same instruction as for the tile or we add a small additionnel portion of water at the beginning of the mixing?
Hi André!
The thin-set used to install the tiles will be a little thicker than the thin-set used to install the KERDI-BAND. The different mixing ratios for installing Schluter® membranes vs. tiles can be found on the back of our thin-set bags or in our thin-set data sheets which we’ve attached here as a reference:

Before you lay down the tray, do you need to seal the bottom of the keri board wall with kerdi fix?
You can seal all seams and joints after installing the tray. This excerpt is from our handbook:
Seal inside corners by abutting adjacent sheets and installing KERDI-BAND with Schluter SET®, ALL-SET®, FAST-SET®, or unmodified thin-set
mortar, centered over the joint. Install KERDIKERECK prefabricated waterproofing corners at all inside and outside corners. When using the
KERDI-BOARD-SC curb, seal the curb to the base and walls using KERDI-KERECK and KERDI-BAND
What's the reasoning for installing drain first with no access...I've installed many with no access AFTER pan was installed...just curious of that thought process
Hi there! The main reason for this is if there are different contractors on a project and the plumber comes through first and installs the drain flange. Then the tile installer would come after to install the tray and the rest of the shower component. Plumbers don't usually work with thin set, they won't install the shower tray. Hope that helps!
What would you put?
Great job
What is the process in this situation where the end of the membrane meets the drywall going out of the shower? Looks like just a tile corner all the way down. Is there anything specific to do there?
Hi James! The profile leg can be installed just passed the KERDI membrane so the tile has an even transition and the KERDI is not seen under the profile from the outside.
so no overlap of kerdi band and kerdi corner in the shower pan corners? I see how this avoids buildup for small tiles but isnt this a waterproof gap?
Hi there! At the 8:20 mark we address Kerdi corners and banding. And yes, a 2-inch overlap is always required!

The "no-access" video has disappeared. Has it been replaced? And it looks to me like you can cement the PVC _and_ install the drain during the normal tray install rather than before the tray. Is there a specific reason to install the drain before the tray if I don't have access to the plumbing from below? I'm about to do my install but I don't want to get to the drain install and go "Ohhhh, THAT is why they said to install before...!"
Hi Scott, you can install the drain any time. That video is primarily for those who have different trades coming in to do separate parts of the shower install at different times.
Here is the No Access video just in case: ua-cam.com/video/dw5VJclorBY/v-deo.html

What is the difference between the but seem and the 2in over lap. I don’t understand why not just do the 2 in overlap like you did where the sheets meet.
Hi there, Either way is fine. It generally just depends on user preference. Some like to overlap the KERDI as the go, whereas others prefer to butt join the KERDI and then cover with the KERDI-BAND. One practical reason for using the KERDI-BAND in some instances is when a small mosaic is being installed over the seam. Since the KERDI-BAND is thinner than KERDI, the build-up at the seam would be slightly less. Hope this helps!
My question is is mortar waterproof, can the water go through the thinset?
Hi Melvin! Good question! The thin set mortar is not waterproof. If the water penetrates the grout and get's to the thin set it will reach the KERDI membrane and go no further. And then eventually, it just evaporates back out through the grout lines. No worries!
Could u do the shower pan before putting membrane on walls ?
Hi! Yes you could install the shower tray first. As long as the 2'' overlap is achieved at every seams, with KERDI or KERDI-BAND, the order of wall and floor installation doesn't matter. Hope that helps!
Can I install the shower tray directly on concrete the same way as shown in the video, with thinset?
Hi Ceeloc, yes, you can install the tray over concrete with Schluter-SET, Schluter-ALL-SET, Schluter-FAST-SET, or unmodified thin-set mortar.

I can't help think of Schrutes Beet Farm.
Can I ask why you would use corner and seems on the outside and not the inside?
Hi there. Since KERDI membrane is installed over the solid backing down to the subfloor and the provided shower tray is waterproof, the seams of the outside perimeter and corner seams of the shower tray must be sealed to create a fully waterproof and vapor tight enclosure. By installing the KERDI-BAND and KERDI-KERECK inside corners over the pre-sloped shower tray, these components prevent moisture disseminating below the top of the tray; therefore, installing the KERDI-BAND and KERDI-KERECK corners underneath the tray is not necessary as moisture will not travel to the substrate. Hope that helps!
Why not start with the pan and then transitions? Shingle effect working up to the walls.
Hi Derek, Either way works as long as there is a 2" overlap 🍊
I'm no genius, however wouldn't it make sense to keedi band the tray to wall joint first, then wrap your walls with membrane overlapping the keedi band at the bottom.....since water sheds down ?
Hi AJ, it can be done either way. The 2" overlap of the KERDI to KERDI-BAND will not allow water to penetrate the seem regardless if it is "shingled" or not. Hope this helps!

Is the bonding flange on the drain installed without PVC glue?
Hi Steven, the flange outlet is connected to the drain pipe with either PVC or ABS glue, depending on which pipe material and corresponding drain you are using.

Is the curb sloped as to drain water back into the shower pan?
Good question! The curb itself is not sloped. When you are setting tile on the curb, the tile must be sloped towards the shower drain using a little extra thin-set under the tile on the further edge from the drain. Hope this helps!
I have a travertine shower with a failed shower pan. Rather than replacing all of the tile work in the entire shower, can I demo and replace the pan, remove two feet of the old travertine and shingle the new Kerdi a few inches above and behind the old shower wall base?

System looks brilliant. My gripe is though the shower proofing is paper and your taking metal trowels to it to flatten/thin set tiles. Aren't you worried you'll scratch the membrane?
Hi Andrew, KERDI is a sheet-applied polyethylene waterproofing membrane designed for the application of tile. Decades of projects behind it, so no worries of a trowel damaging the membrane when installed correctly. Thanks!
Can I install without pan and use the wall membrane instead for the bottom of the shower and then use grout to slope to the drain?
Hi there! Apologies for the delay...
The options for sloping a tiled shower floor to the drain are a KERDI-SHOWER-TRAY or a Portland cement mortar bed. The sloped mortar bed would need to be installed prior to the KERDI membrane so it wall be waterproofed on top and the water would slope to the drain and not saturate the mortar bed. The KERDI on top of the mortar bed would also continue up the walls in accordance with our Shower Systems Installation Handbook to create a completely waterproofed and properly sloped installation from the shower head to the drain. Neither grout or thin-set would be appropriate materials for creating a slope for the shower floor.

Then for the flood where I walk into the shower, could I Juilliard the floor height up to the shower pan height by using plywood Then cement boars, and cover the cement board with Kerdi and seal the Kerri to the shower pan? Do that instead of building floor up with mortar?
Do you not have to mortar any of these products onto cement board??? It looked like it was just drywall on the walls and plywood on the floor.
Good question! The waterproofing Kerdi membrane can be applied to any approved backer board. You can see all of the requirements here: sccpublic.s3-external-1.amazonaws.com/sys-master/images/he2/h48/8984381980702/Shower%20System%20Installation%20Handbook.pdf
It can go over drywall, but it’s too easy to just put up some cement board and it makes a more solid base for the tile.
Two Questions 1). can I use hardie backer up against the Kerdi pan? 2) what is the depth of a Kerdi pan? Just looking to see if I can go curbless.
Hi Michael, would you be able to give our Product Support team a call to discuss your project in a bit more detail, and they will be able to advise from there. 800-472-4588 (US) or 800-667-8746 (Canada). Thanks!
Why not overlap and join the seams together with kerdi band in a process that water never runs directly into a seam? For example..first membrane the shower pan. Then apply kerdi band and corners to the pan and wall board. Then membrane the wall over the kerdi band so the seams are never in direct contact with the direction of water flow. The schluter method is putting too much faith in the technology of how the kerdi band adheres to the membrane through the thinset during the curing process. This process could result in failure given the fact that thinset isnt waterproof and its possible theres not a 100% connection of the overlapping membranes. Installing it in the overlap method I stated in beginning of this post takes out any possibility of water flowing directly into any seam.
I was thinking the same exact thing. Wouldn't that be a safer way to go?
U are absolutely 💯 correct and Idk y shluter doesn't not apply the proper water shedding techniques and they need some kind of closed cell product to water proof 100% or it will leak after a few years this shit is crazy stupid and only a small amount of us have enough sense to see this.
so your saying do the shower pan first, connecting all the corners and membranes to the board then do the walls over that so the wall membrane is the “front” piece of membrane showing and not the corners? sorry just having trouble envisioning it. the way you stated makes more sense, no seam contact with water. just wanna clarify.
@@nickroussain317 yes no direct seam contact. I call it the shingle method. Shingles overlap so water sheds over the shingles. Same principle here. Obviously the technology guarantees full waterproof either way but for me as the installer I like having extra piece of mind knowing that any water moving towards the drain will not run directly into a seam but rather flow over the seams since they overlap from the top down like shingles. Its still the same technology so the manufacturer should still warranty the product as long as youre still using the mortar they recommend and doing the manufacter recommended overlap which is usually like 2"
Will this membrane accept heavy tiles. i plan to use durock for my walls for that purpose. is durock an overkill since the video depicts the use of regular drywell. Thanks
Hi Carlos, yes, KERDI will hold heavy tiles. Regular drywall is all that is required beneath KERDI, however cement backer board and other solid backing materials (listed in our Shower Installation Handbook) are also acceptable.
Here's our Shower Installation Handbook for reference: sccpublic.s3-external-1.amazonaws.com/sys-master/images/hd1/h93/9007208038430/Shower%20System%20Installation%20Handbook.pdf

@Pat Capo durarock?banding? Do you mean drywall mud and tape? Did you prime and seal as well as do a coat of acrylic paint,or better yet mold resistant drywall,mesh tape,and coat with rubber paint before the kerdi system?
Edit: oh did you mean cement backer and mesh tape? I like to give that the same treatment as mold resistant drywall. I know you've probably finished your project by now,but ive made just about every mistake you can is all.

I am creating a custom enclosure for my bearded dragon and considering using Kerdi. Is Kerdi shower kit and mortor safe for marine life?
Hi Pam, we don't have any specific information as to whether those products are safe for marine life. However, our Safety Data Sheets are all available on our website. You can find them on the product page under "Downloads". They may be helpful. Also, since all of our shower components will be encapsulated within the tile assembly, you may want to focus on the suitability of the tile and grout that you'll be using in your application, as they would be the exposed products. Hope this helps!
Can I use Kerdi or Ditra under the curb?
Hello there! It is best practice to install the curb directly onto the subfloor.
if i have enough material, why would i do a butt joint? I am assuming i can just overlap ?
Hi there, since KERDI-BAND is half the thickness of KERDI, covering a butt joint with KERDI-BAND will a be little less build-up than a lap seam, which may be helpful when installing small mosaics. Otherwise, either method may be used and it's just a matter of preference. Hope this helps!
I have installed my walls (Kerdi board) but haven’t taped yet. I now think I’d feel better if I trim the wall bottoms to accept the pan after thin set, cut the pan to fit stud to stud, remove the pan and tape the walls, install the pan, Kerdi fix where the walls meet the pan and curbs, tape the pan and curbs (my kit uses membrane on the pan and curbs). Would you talk me out of this? If yes,
why?
Hey Gbear, could you give our Product Support team a call to discuss? They'd be best suited to advise! 888-472-4588 Thanks!
considering giving this a shot on our own. I've seen the system on a lot of home improvement shows. Question is, how does one install glass doors/panels into the foam curbs?
Hi there! You can use the DECO-SG to install the glass on top of the curb or you can use KERDI-FIX and anchors with other framing. Please contact Customer Service for anchor installation instructions. Hope this helps!
Yea ...opps
The kerdi is a joke, nothing will properly anchor in to styrofoam, beat to has monolithic solid cement slab pour with inter grated liner
Yeah, that concerns me..semms like it should have wood underneath or something.
In 20 years never anchored a door set into a shower curb or tub edge, that is ripe for leaks. you lay down a double bead of silicone for pre-fab units. Custom panels depends on the install type but are usually similar. Those yelling about hot mop and vinyl liners on here are just afraid of the inevitable. Currently using this system to replace a hot mop/mortor bed custom job that apparently leaked for 20+ years...had to replace 90% of the subfloor in the bathroom and a couple floor joists. This system is so much easier and lighter, never had a leak in all the times I've used it.
I have a custom shower floor size, larger than the sizes that you sell is there add on pieces for larger shower floor sizes?
You can always extend our shower trays with drypack mortar. We recommend giving our Product Support team a call though, they can talk you through some options or put you in contact with your rep!

I have access to drain, in fact it sits above my subfloor and Kerdi shower pan. Do I cut that drainpipe two inches below the bottom or two inches below the top of the subfloor? Does the Kerdi PVC drain assembly then get glued to my drain pipe or does it just fit into place? Thanks.

Hi Chris, either one is fine! Thanks.
Can someone advise me regarding the Schulter Kerddi Cub ? Does it have to slope inward to the shower base?
Hi Rocky, the KERDI-BOARD-SC curb is installed adjacent to the shower tray (that has an integrated slope). Here's a link to our installation handbook: sccpublic.s3-external-1.amazonaws.com/sys-master/images/hd1/h93/9007208038430/Shower%20System%20Installation%20Handbook.pdf
I installed my shower, but missed the part where you discuss “memory” in the corner pieces - I could not get them smooth due to the shipping fold - blocking them to flatten them out created a couple of other dimples (oops). I guess I just cut those flaws out and put a Kerdi-band patch over the flaws?
Hi there! Yes, you can definitely cut out any imperfections in the KERDI and patch over the flaws provided at least 2 inches are achieved at these areas. Hope this helps!
Use of a hair dryer would've been beneficial to fix those folds.
@@surfingweb7176 I actually tried futzing about with it until I pulled it out - washed off and heated it with hot water, dried it off, tried again. Eventually blocked it (fail - mentioned above). Finally just cut a long piece of band and put a patch over the pieces flattened by slicing off lumps, taking care to 2” overlap. Result was nice but not so much mid-way. Yes the hair dryer (or heat gun) would have greatly improved. Now I know. Thx.
Very nice video thx
Is it always necessary to water proof between the Ditra membrane and the Kerdi curb with Kerdi band?
Hi there!
KERDI-BAND is only necessary at the DITRA to curb connection when a waterproof floor adjacent to the shower is desired. Otherwise it's optional.
Hope this helps!
@@schlutersystems1 Super helpful! You guys are the best.
So the base have to be level ?
Hi Andre! Yes any leveling of the floor must be done prior to the installation of the shower tray. Otherwise it will affect the slope of the shower floor. Hope that helps!

Can I use modified thin set mortar for the schluter orange Waterproofer on Sheetrock?
And can I use modified thin set mortar on foam shower tray on concrete?
Hi there, to install KERDI on sheetrock, you would need to use an unmodified thin-set or Schluter ALL-SET or FAST-SET. Same for the trays. Thanks!
@@schlutersystems1 thanks was watching your video and they didn’t mention if it was modified or un modified
I don't understand why all the parts that get applied in an order that seems to be backwards. If water were to get under any part it will stay under forever. you example starts from the top down basically. Why don't you start at the drain and work your way up installed the pieces so the higher pieces fall on top of the next going down.
Hi Dave! The sequence of membrane installation can vary provided that a minimum 2" (50 mm) overlap is maintained at all joints and proper connection to the KERDI-DRAIN is established. Also, top-over-bottom or shingle laps of the membrane are not required. So, It does not matter which layer of KERDI goes down first in order for a waterproof seal to be made.

Hi there! My wife would like me to frame a bench into the rough shower. Any problems with a 48x60 shower that uses a 48x48 shower pan and has a 48x12 bench on one side? I'd be using the 48x48 Kerdi shower pan and then just use the membrane to waterproof the bench section and up the walls.
Sure! This video gives you the steps for installing the bench with the tray and waterproofing the connections: www.schluter.com/schluter-us/en_US/video_shower-systems/video/Jn58yNMqvSU/playlist/PLEFjeySFJM-Bqg39YC-9A5d9iLu547R0j
If installing 2 curbs (90 degrees); how do you waterproof the “top” of the inside corner? They dont make a patch for that. Turn a corner inside out and cut the part that would now lay on the top? Also need to add a small strip of kerdi band to top of that?
You'll need an outside corner and some KERDI-BAND to waterproof that area. This video explains how to waterproof the whole 90 degree corner of the curb, inside and out, in detail: ua-cam.com/video/IbPEFlN94nU/v-deo.html
Yep u can but it will be a little bulky on that corner than it will leak within a few years this system has a bunch of flaws and u just found one
Do you have to use the supplied curb? Just wondering if it's possible to have a curbless shower and completely waterproof the floor still using this kit.
Hi there! We have trays designed for curbless applications and yes, the surrounding floor would need to be waterproofed too (Ditra for the win!). You can have a look at our Curbless Shower section on our website here: www.schluter.com/schluter-us/en_US/curbless-showers

I would never put drywall in a shower even with this system
That’s why this product was invented, to eliminate the need for more expansive substrates. Lowering the cost, making it more available.
Using this product doesn't lower the cost it actually increases the cost
@patrick wooten agreed just makes it easier for homeowners to install
When you understand what waterproof is than you know water could never touch the drywall bud
I have had subs use this on all houses I build and remodel, we put it on over drywall. It is the best thing I have ever used in over 25 years. If installed correctly you will never have problems.
So this can go straight to Sheetrock or greenboard?
Hi Clayton! KERDI can be placed over any Gypsum wallboard meeting the ASTM C1396/C1396M standard. Please see the Shower System Installation Handbook for more solid backing options for installing KERDI membrane.

Just a question. If modified thinset is a food source for mold, doesn’t that mean every shower that has ever been installed without modified thinset has a mold problem? That is basically what Schluter is saying but I find that hard to believe especially because I have never once in 25 years went back to a home because there is a mold problem. Overall, their shower system is pretty darn good. There are just way too many steps, seams every where, and their fabric is too thick and doesn’t crimp. I had a rep install a kit in our showroom and I had to tile it. I had to shave the back of the tile to get the cuts around the curb installed. Multiple layers of fabric = thicker bumps to tile over period.
Carlos Cortes mortar of any type isn’t a food source for mold...
But they tell you it is and that you should use unmodified thin set.
Carlos, wanna give us a call? We can fill you in on the details.
