The guy I am working for is upset because he installed some waterproof sheetrock on the walls in his bathroom. The tile setter says he has to tear it out.
It's on the walls and on the wall area surrounding his large oval tub.
It's not something that will get wet, like a shower. How come they can't just install cement board over it? The tile setter says that won't work because moisture will get trapped behind the cement board.
What moisture? It's just the walls in the master bathroom and the tile will be from the floor up to about the light switch height.
The box area the tub will set on is plywood, so cement board will work over that just fine.
My question is....
Why can't the tile be installed on the wall areas and wall area surrounding the tub over the waterproof sheetrock? What are his options if it won't? Install Kerdi over the sheetrock instead of cement board?
