The idea around that is to put your wonder board / concrete board around it. Then as you’re laying your pan, you can apply the water proofing to ensure a water tight seal. Putting waterproofing membrane underneath is cheap insurance, but not necessary
Never use plywood in a shower. It will swell and cause the tile to fail. Cementitious backer board is acceptable -- it will soak up water but will not expand or deteriorate. Cement board should be sealed with Redgard or Hydro Ban. Foam board products like Kirdi or Hydro Ban Board are the best choice, as the foam is completely impervious to moisture. I prefer Hydro Ban Board because it's stiffer and the membrane is tougher, but big box stores don't carry it, at least not in my area. I order it online or, in a pinch, drive a couple of hours to a supplier. Also, always use tape on inside corners.
What code? PT wood warps like crazy when it dries. If you’ve got enough water penetrating that deep you’ve got bigger problems than water on your 2-bys.
Concrete is a porous material; water can be absorbed through capillary action and transferred through concrete. Thus, wood that is in direct contact with exposed concrete must be pressure-treated to withstand the moisture that the concrete can draw in.
I like the bench but shouldn't it be installed over waterproofing membrane?

can you cut the shower pan around the bench
Teachers, I want to continue learning from you.
Thanks for the video. Im doing this project now and this is very helpful
Thank you! Please subscribe to our channel for more.
@@TheBuildingExpert can I use durock instead of plywood?
Shouldn't backerboard be used instead of plywood?
can go over the plywood - just like the subfloor
WOW very nice
what kind of nailgun is that?
Very helpful

Very good man
You guys build it right but just skip the most important thing the wood that touches the floor has to be pressure treated wood by code

True you will have a bigger problem but it should be pressure treated
He is in the second level it does not need it
Make it wooden with the help of the Woodglut instructions.
