Good day,
I just joined this form as I have found a great deal of info here. I am currently redoing our master bathroom and will be putting in a custom tile shower, tile floor, tile tub surround and will be tileing a wall behind the tub. I am using Schluter kerdi, pan and curb for the shower and also plan on putting kerdi on all vertical tile surfaces. The one thing that I have not found information here on is if 1/2" plywood is ok behind the kerdi. The tile store's installers I am dealing with recommended that I use plywood rather than cement board or drywall. I understand the drywall reasoning but am not sure on the plywood being better than cement board. They said it would be easier to install than the cement board.
The wall that the tiles will be going on is an exterior wall 12' l X 8'h. 4 ' of the exterior wall will be the shower with a glass enclosure to separate the tub. I will have 2 4' walls running perpendicular to the main wall that will be the end of the shower and tub. I have a good vapour barrier on the exterior wall but I am wondering if having plywood in between the vapour barrier and the kerdi could trap moisture if there is any leakage and ultimately cause the plywood to rot.
Sorry for the long post and thanks in advance for any insight you may offer.
