Learning how to waterproof a shower is one of the most important things you can do during a bathroom renovation.
Wedi is a great waterproofing method because it's been around for over 30 years, is easy to use, and comes with a 10 year warranty.
The first step should be checking the stud walls in the shower. They should be plumb and even with each other.
If a shower niche will be installed it's best to plan the tile layout and location of the niche before adding the wedi waterproofing panels.
Apply a bead of wedi joint sealant to the tub lip then set the first wedi building panel in place. The first screw and washer should be 6 inches above the tub or shower pan. Then a screw and washer should be added every 8 to 12 inches.
Add wedi joint sealant where wedi panels meet each other. Once all the wedi building panels are installed apply wedi joint sealant to the seams, corners, and shower transition. Then smooth the sealant with a 3 inch putty knife or wedi corner trowel. This will ensure the shower is 100% waterproof.

I tip my hat to you as a professional. The information you're providing is correct and that's the way I like to do it. I found information in your video refreshing to see that you follow the same steps that I do. Watching you work is like attending a wedi seminar. these techniques were drilled into me from the minute I started working with this product. Thanks for giving folks the right info
thank you, we appreciate your support and enjoy sharing what we learn at seminars or our reps
You guys nailed this tutorial. Wedi couldn't have done it better.
Great video thanks for posting 👍
As always, good info on building a waterproof shower with modern products.
thanks Sal, enjoyed your latest video. Great tips on how to make those tough cuts on stubborn tile!!
It’s Sal approved which is always a plus! 👍
@@HomeRepairTutor great video,, do you use the same materials anf method for a steam shower?
GREAT video guys! Questions on corner beads: What type of corner bead (Wedi to Gypsum) do you recommend; Do you use Wedi sealant on the exposed edge of the Wedi board before putting on the corner bead? And do you recommend using Thinset, mud, or something else to finish?
Great video, it's nice to have a refresher prior to doing a install.
Thank you, are you doing the same project?
@@HomeRepairTutor Yes with wedi.
@@Oakmooretile nice, it's a great product. Are you doing the curbed shower or curbless?
@@HomeRepairTutor bathtub.
Great video fellas!!!
+VCG Construction thank you
Can you post a video doing the Water leak test? Similar like you do it to Shower Pan Liners... thanks
I really needed to know how to waterproof around the valve/diverter body, shower head, and I have body sprays and a second connection for a wand. Hope this works right!
Great video, thank you! Do you ever use the Wedi tape and in which situations?
Loved it. Can PVC panel with adhesive be used over the Wedi backboard or has to be tile only?
So in a previous video where you compared 3 ways ( concrete, kedi-board & wedi board) you lined up the bottom of the board with the top of the tub on all sides. In this video you overlapped the wedi board on the "back wall" only. Can you give a description as to why this decision was made? I just picked up some Wedi and am about to start placing it i on the wall. I can space it out so it overlaps, but I need to do that now. Why did you do this two different ways?
Great video. Can this wedi board go down on top of a concrete floor as a insulator for cold tiled floor.
Is the joint sealant universal in adhesion performance with other surfaces? I can understand that it adheres to the Wedi's blue foam membrane but the tub ceramic, fiberglass, plastic surfaces? And the adhesion to thin sets and mortars and drywall?
@Home Repair Tutor can you used other niches? Is weidi compatible with other plastic niches?
Going from a fiberglass tub and surround to a shower using an onyx pan. Looking for whatever I'm gonna need to tile from the floor to the ceiling and a niche
How well does the wedi sealant adhere to the tub? Should i apply an additional silicone application between the tile and tub at the end of the installation?
You use thin set mortar directly on the wedi?
I am using a delta r2200 diverted/valve which is not round. Any ideas on how to water proof the area where it meets the wedi board? Of course cutting a round hole won’t work for this application so I can’t use a standard wedi round gasket. Thx!
Interested in using Wedi for a tub surround. Has anybody had the sealant fail? Curious what the longevity is like.
can you fit uPVC or Laminate panels on to Wedi boards?
What thickness of Wedi board I need for 600mm by 300mm tiling on a stud wall and the best suppliers
Did you cut any wedi from the back of the panel by the lip of the tub?
I am confused, So which is the BEST way the Wedi Board over the Tub Lip or sitting on top of the Tub Lip ?
Could we use the Kerdi Fix on Kerdi board over the washers the same way it's used the sealing on Wedi board? They seem to be almost the same technology. Looks a bit cleaner with Wedi. Thank you for all the info. God Bless you guys for sharing the info.
+Chivu Florin thank you, unfortunately we can only recommend the method Schluter recommends with KERDI-BOARD, to apply KERDI-BAND over screws and washers. We agree that using just KERDI-FIX would be awesome.
I know this reply is late, but Schluter and Wedi are competing products and they both will void warranty if you use another brand. For an example, my Wedi rep says if I use a small Kerdi-band on a section of a shower/bath job, it voids Wedi warranty. Very silly, but they both really don't want you to use any competing product. Apparently Kerdi fix is completely different from Wedi joint sealer although they seem to share same function for each product, but that comes from my Wedi rep.
Could you rabbit the back of the Wedi panel at the tub instead of installing fur strips?
Am assuming it’s a mock up tub for Wedi product demonstration. Because there is no insulation.on brick wall.but good job on showing how to water proof tub surround..great job
No mock up, this was a real bathroom. Brick was interior to home and the bathroom was in the center, no outside walls. Otherwise we’d use Roxul
Perfect timing!
+DJ Primo cool, what kind of shower are you building?
Home Repair Tutor 38x38 corner stand up shower :) I just got the exact same niche as well. I'm tiling the walls and using pre fab pan.
+DJ Primo nice, is that a custom pan?
Home Repair Tutor no but it's gonna be a custom installation! lol
+DJ Primo lol, every shower is custom. If you're using large format tiles let me know if you want T-Lock samples. It's a great leveling system
Awesome as usual! Thank you! Is it absolutely necessary to fir out the main wall in order to have wedi board go over tub flange and sit on tub deck? Just curious on all the reasons for furring out that wall. Thanks again!
It's not necessary but will save money, you won't have to use as much Joint Sealant
@@HomeRepairTutor i bought this kit based on your recommendation and awesome installation video. Will be installing soon. Also planning on buying your membership here shortly. You guys are the best! Hope you're being financially rewarded. If not its sure to come. Keep up the awesome work.

Can I use Wedi for a steam shower
Can you tell me why the back panle ISN'T "sitting on the tub lip" like the other 2 panles?
Just a quick question...why did Steve not fur out the other walls to bring the wedi panel down to the tub, and instead put the wedi panel on the lip of tub? Love your videos....will be ordering from you soon!
+hllywd964 great question. In order to have the wedi flush with the 1/2" drywall we needed to place the panels flush with the studs. Hope that makes sense. Let us know if you have any questions, we'd be happy to help
I used Wedi a few years back for a tub surround. Their instructions say to notch the lower edge of the board (from behind), place a bead of sealant in the notch, and put it over the tub's lip, leaving a slight gap from the tub's finished surface. It worked like a charm and would eliminate the need for the strips on the back wall. BTW, despite the cost for Wedi board (it ain't cheap), I absolutely love it. Show me another equal quality product that's installed and ready to tile on the same day (imagine doing a walk in shower without Wedi). Thanks for the video.
What are the disadvantages, if any, to half-inch Hardie Backer Fiber Cement Backer versus Wedi board
@@kenhoward127 Goboard is just as good and more readily available, at least where I live.
Ive been watching a lot of your videos and I love it and learning a lot. But I thought the board or all board sit on top of the tub flange about 1/8 of an inch?
Lookup "wedi.de tub-walls-and-tub-enclosures" in your favorite search engine and see for yourself.
@@s.t.5003 thank you I’ve been stuck, couldn’t find this exact information to finish my Basement install. Much appreciated
Where do you buy all this stuff?
I have searched the internet and many Wedi youtube videos, and have not found an answer to this scenario. I have a shower where a couple of the adjacent walls do not meet at a 90 degree angle (as an example, let's say the walls meet at an inside angle of around 130 degrees instead). When installing the Wedi boards on those two adjacent walls, do you recommend that I put a mitre cut on the edge of each of the adjacent wedi boards. For example, if the walls meet at an inside angle of 130 degrees, I would put a 25 degree mitre cut on each of the adjacent wedi boards (180 minus 130 = 50 divided by 2 = 25). I think I would have to do this in order to make sure the Wedi sealant still has two edge surfaces that butt up against each other to make sure the joint is totally sealed. Is there anything else I should be doing to completely seal that joint? Or, is the wedi sealant still sufficient?
Does wedi not need tape in joints just sealant?
Why did you drop the back wall board over the tub lip but the side walls on top of the lip?
Could I use a combination of wedi and kerdi to make a custom steam shower? Or would you just use wedi or just use kerdi? I'm leaning more towards wedi cause its cheaper.....
I would recommend just Wedi they have panels specifically for steam showers
Nice system. Never seen this one.
I assume its foam. .. is there any flex from smaller format tiles installed on this?
I assume wall use only.
yes, foam with cementicious coating on each side. There's not much flex with wedi, it'll work well with any type of tile. We use the panels on the walls and their wedi Subliner Dry on the floor. It's a great option.
@@HomeRepairTutor Yes, there is flex. You need to consider the weight of the users. Tiles are loose since the wedi panel is compressed in the area where the person stands. Now, I am not sure if the contractor installed waterproofing in addition to the wedi system. I need to repair but don't know if I can just remove the compressed portion or whether I have to remove the whole floor and some wall tile to see whether we have waterproofing.

Hey guys. Love the channel. I just installed the wedi board base and walls. The thinset was a little thin but held its shape even when left for a while. Will I be okay?
You should be okay if the correct trowel was used and the thin-set was mixed per the directions. Which kit did you use?
Home Repair Tutor 36x36 kit. You were right. Once the thinset was dried it’s in there. I think I did 2 parts thinset mix. One part water.
Where can I purchase the kit?
Great demo, very instructive, thank you!
Its a Dremel Multi Max by the way. I have the Multi Max 45 which has a quick release button. This is the best tool for flush cuts on the market.
On the niche install, I think it could have used more glue to hold it down. It had no nails or screws attaching it directly to the wood studs, only some on the ends. It did not look secure enough.
How does Wedi compare in functionality and cost over Schluter Kerdi board, or Hydo board?
For a small RV bathroom install, this type of backer board is ideal for low weight and prevention of water leaks. My question is, how do you hold up the vertical wall tiles on Wedi board? You still have to use thinset mortar right? Can I use Polymer instead of water in the thinset mortar mix and also in the tile grout? Reason for this is - my RV is under constant movement like an earthquake. Polymer gives a rubber movement dampening effect on the tile and they don't pop out. Not sure if you can use Polymer on these new materials.
I went to the website but didn’t see a store or any products for sale
Why do you put the Wedi board to the top of the lip for the front and back of the tub? But the back Wedi board sit in the tub?
What’s the lifespan of this panel?
I just do not trust joints that are caulked and not somehow counter flashed like the Schluter or USG system. In new england the building moves entirely too much to rely on caulk to hold a joint together. Otherwise great contractor, guy knows his stuff.
what would the cost to purchase, and install the tub, as well as the board be? Obviously, exact numbers may fluctuate, but a rough estimate is all i need. Also, could you install the board over the flange on the tub?
+Joe G we can give the material cost. Tub is a jacuzzi and was $400. Wedi tub surround kit ranges from $329 to $522 depending on the dealer and shipping cost. Board can go over the flange if the wall is shimmed
Home Repair Tutor you mean jetted for $400 ....and from where?
oh ....not jetted so jacuzzi makes regular tubs?
For a DIY'er, any real advantage for this over Kerdi? I've done sheetrock which this is similar too, but somewhat new to tiling.
wedi is a bit faster than KERDI over drywall. The wedi building panels also are waterproof even if the surface is scratched or cut, which is different than KERDI or KERDI-BOARD. Both methods are fantastic and solid methods for waterproofing a shower. What kind of project are you working on?
Remodeling one 3-piece bathroom as is and for the second tub to shower conversion.
let us know if you'd like help with the wedi if you go that route. We've been helping folks with design and materials. It seams to be helpful to have a second opinion on what to get. Feel free to send me an email with any questions, jeff@bathroomrepairtutor.com
Home Repair Tutor Thanks Jeff. On vacation this week, starting demolition when we get home and I've been checking out the premium lessons you offer.
Anthony Raynor have a great vacation! You might like the lessons, lots of detailed videos. We also answer a lot of questions while people are in the middle of their project. I think that's almost better than the videos
Thanks. Why did you put the Wedi on top of the tub lip on the front and back wall, but over the lip on the large side wall?
It is explained above (to be flush with the drywall)
@@bernarddebbasch1106 Ill have to re watch this vid for a 3rd time,.... I didn't hear him say that.
It's good stuff ~ but at 5 times the cost of hardi-board & redgard, the price is silly.
Great video again guys! I've been having withdrawals the last few weeks without one LOL. One question though because I've never worked with wedi, do you leave a small gap, 1/8 or so between the tub and the bottom of the first panel for expansion/contraction and weight from water and people? Thanks again!
lol, glad we could get a video out this week!! Thank you for the kind words. We don't leave a gap but rather use the wedi joint sealant on either the tub (if shimming the wall) or tub lip (if not shimming the wall). The sealant likely adds a 1/16" to 1/8" buffer for expansion/contraction. Great question.
Home Repair Tutor one more question....do you sell this same kit from you're online store?
+460 S&W we do, it's called the wedi Tub Surround Kit. We also do custom shipping quotes
The debris in the bathtub is painful, its gonna scratch.
That was always the thing I was super worried and careful about. I always covered tubs with a lot of protection so they wouldn't get scratched.
There needs to be more sealant in the corners and on the seams. Wedi calls for at least a 1" wide strip on each side of every seam (including corners) that must be within 1/16" and 1/8" thick.
keep in mind that 1" on camera doesn't necessarily look like 1" - this shower was waterproofed and installed to Wedi specifications.
what is the easiest way to get excess wedi off the tub?
use a razor scraper (carefully)
I really need a clarification please - you started 4" on top of the tub for the screws and then every 12" for the fasteners. I've asked this to my local area Wedi tech rep, and he's a real cocky know-it-all saying his way is the highway and you always start 12" from bottom whether on a shower pan or on top of a bathtub. I assume you use 4" because of a know-how after having done many remodels. Would you explain why you start at 4"? Have you seen Wedi bow out after tile job when started at 12"?
first, it stinks that your rep is being cocky. We're all students and nobody is a guru, period. We were also told to start at 12" for showers due to the tendency for the Wedi board to bow inward and thus compromise the joint it makes in the shower pan rabbet; recall, Wedi shower pans have a rabbet joint that receives Joint Sealant and then the Wedi backer board. However, that rabbet joint doesn't exist for tub showers. Therefore we're okay using the screws at 4" above the tub deck.
@@HomeRepairTutor yep the rep is a douchebag...I ended up going with Wedi because of you guys but he's making me regret it. I'm going to start at 4" as I see you guys do it and also see it on the manual illustration for the bathtub instruction where I see the screws pretty close to the tub deck. Thanks again!
Very helpful video - I am about to install Wedi around my new bathtub. I cannot find any information about what kind of thinset and trowel are required with the Wedi system. I know Kerdi requires their own special trowel and unmodified thinset - what do you all recommend for Wedi?
Thought this product is only used for tile install?
Thank you for the great film! The handsome contractor Steve in this film should be in Hollywood rather than in somebody bathroom though. Hollywood overlooked for sure!
My contractor installed a waterproof sheetrock, but I want now a niche, like in this film. Can I cut out a rectangular for the niche, because wooden studs are not cut out or I need to remove corresponding sheetrock piece completely? My contractor didn't put any washers, would it be a problem? And if that sheetrock installed on the whole wall till the bottom already, can I put tile in the way that sheet rock is behind the tub and seal the edge somehow differently than shown in the film?
Is the sheetrock going to have Kerdi or another sheet membrane of it? That's the primary concern
I have a green (waterproof) sheetrock, 1/2 in. May I also know where I can find those washers, are they special, waterproof as well? Thank you for the quick respond. I know that I would need to complete the project myself, and though did a lot of stuff before, this is new for me, since I've never worked with thinset. You advertise free course, where is it? When I clicked on the link provided it shows $100, I assume it is more extensive course, is it so? And if you pay $100, for how long you can ask questions, is it for a month? Thank you for the quick respond and good film.
How long do I wait to do a water leak test? Wedi is installed and I want to test to make sure everything is good prior to tiling. Thanks in advance.
Wedi’s handbook states in as little as two hours after Joint Sealant is applied
Why do you shim the back wall with plywood (to bring the panel out and overlapping the tub lip), but then set the side panels on top on the tub lip (no overlap)?
Ah, I read in another comment that it was just to save money on the sealant.
Ya I was confused as well, But I see by Kohler's instructions they want the Water Resistant Board (Wedi Board) over the Tub Lip. So maybe the best way is to the Wedi Board over the Tub Lip on every side?
I have heard endless arguments over placing the boards over the lip, keeping them on top, and even leaving a very small gap. Provides me with endless confusion before tackling a project. I noticed here with the back wall you installed it over the lip all the way to the tub. But with the side walls only put the board at the top of the lip. Why?
Same here, I noticed my tub flange lip isn’t even straight across so I’m definitely not setting it on top of the lip. My flange is also like an 8th thick so even worse. I noticed the one he’s working with is like a quarter thick and it’s actually straight. In that case I would actually do it that way but not with my jacked up tub.
As I understand it, some boards can wick water. Because of this, I am going to install mine on the top of the flange after I put flashing around the perimeter. We’ll see how it goes.
Do you guys use Wedi or Shluter these days?
What he does not discuss is the price. You have to special order a pallet from Lowe’s or Home Depot here in Texas. Over 2k for a pallet! I wish I had enough to do my shower though. I am sure it is worth the price!
Go with Goboard instead. Got it from Menards at $26 per panel of 5'x3". The special caulk and screws to use with them you can find them online at Amazon or Contractors Direct. Just as good as Wedi board.
Why did you just put the Wedi panel on the top lip, instead of over lapping?
Cool idea but there is no way that is enough sealant in that kit to do the whole job concerning you want to be generous with it
We used one additional tube of sealant; had we not overlapped the main wall over the tub lip we would have needed two extra tubes
Did you purchase any Wedi products to make this video? I can't be sure....
Great video and voice-over, can we tame the use of the word wedi in future? Sealant can be called sealant not wedi sealant every 30 seconds, we knew it was branded by Wedi from the beginning of the video.
Thanks for taking the time to film your work and explain to the viewers.
Thanks Ryan, the reason we say wedi sealant is because people have asked if they can use silicone or liquid nails with this system. The answer is no because silicone isn’t great in this situation and liquid nails literally burn holes through the panel and pan. While it’s painfully obvious to you (and me) that we’re using wedi, you’d be surprised at the questions we get. And yes, we bought all the materials for this waterproofing 👍
I was just messing with the sarcastic comment - Any authorised seller selling Wedi Panels should be telling the customers under no circumstances should their own sealant not be used. It's is a completely different composition and viscosity to silicone and liquid nails hence them having it manufactured and putting their name on it....
I wasn't insinuating Wedi were giving your free stuff from to promote their stuff, just taking the mick that you used the name about 60 times in the vid lol.
Nonetheless a great video, i'm a big fan of your channel and how you present your videos, it really does give the DIY'er or the "knows nothing person" an idea of how bathroom work can be tackled even if we decide not to carry out the work ourselves.
Over and out.... and a thumbs up.
no problem, sometimes it’s hard to tell if someone’s being sarcastic. It does take a long time to make videos. For every hour of footage it’s another 1-2 hours of editing. Since we shoot and edit the videos ourselves I can get a little cranky.
isn't the Nitch a Dr Zeus character?
Anyone doing this cover the inside of the bath before you start , step 1
totally agree
I can't believe they didn't do it!🤯. Thats a rookie mistake.
down a shot every time he says Wedi
neesh is the pronounciotion your looking for, not nitch. but great video :p
I thought you were not supposed to put a niche on an outside wall, and why did you not put insulation between the brick and wedi ?
Real question not a heckler
Great video but u still haven’t learned to protect the clients tub, 🤔🤔🤦🏻♂️🤦🏻♂️🤦🏻♂️🤦🏻♂️🤦🏻♂️
You’re correct, we should have protected it. This tub was in our investment property and was fine but totally agree
Come on a few hours hehe…but Stevie is a master anyway and the bathroom has a terrible design .Stevie would choose better tiles I'm sure.
Eve should have been more careful in the tub should have placed a drop cloth he must have scratched the hell out of it
It was fine but yes, we typically use a drop cloth
😂
Schluter is better
It’s pronounced “neesh” people as In rhymes with sheesh
That tub is so destroyed .
The fact that you don't have a drop sheet and tape off the tub is beyond unprofessional. All the concrete bits of the wedi panels on the bottom while being walked on will scratch the crap out of that brand new tub. Takes 10 minutes to properly cover the tub well, just complete laziness. Prep work is key to a successful job. I'm honestly beyond shocked.........
Drink every time he says Wedi
Would be better if Americans say 'neashe' instead of 'nitch'. It is not an English word. Why not write it different if you want it to be an English word. I found out after hearing 5 times 'nitch' that you meant niche. nitch sounds like snitch or bitch.
