Does one need to install cement board on the ceiling in a shower stall or just the 3 walls that get direct water?
It would be easier to install blueboard on the entire ceiling over the resilient channel. The shower stall is for my tenant below me and the ceiling will be tiled over.
Any info would be appreciated.
