In the middle of remodeling a bathroom, two sides of the shower area are surrounded by interior walls - wood framed 2x4 studs.
Thinking of framing in a few recessed nitches on that wall for sponges, shampoo, body wash etc...HOWEVER...the wall is only 3.5" thick (2x4).
The other side of the wall is a hallway, so I will have sheetrock covering the back side of that wall. The front side of the wall will have a 1/2" cement board over the wood framed wall, then 1/4" wall tiles, which makes the maximum depth of that nitch 3.5" + 0.5" + 0.25" = 4.25" measuring from the back of the sheetrock from the other side.
I don't think I can just tile over the back of that sheetrock (after waterproofing) can I? I assume I need a piece of cement board on the back side as well? Plus the tile over it. That reduces the depth to 3.5" again.
Is 3.5" enough for a shower nitch? Seems awfully shallow...should I just forget it?
