I have low ceilings in my basement bathroom. The fan is just outside the shower. Currently the ceiling drywall in the shower is the same as the rest of the bathroom (i.e. not greenboard). Knowing that the direct water will be minimal, but will be mostly steam and spray, I am trying to decide between the following:
A) Leave as is as.
B) Coat with RedGaurd and repaint (maybe with water resitent paint).
C) Tile over existing drywall (likely with a coat of RedGaurd).
D) Cut out the drywall, install backer/cement board and tile.
Option A is the easiest, but I would worry about rot. Option D is a real pain. At the moment, I am leaning toward option B.
Here are some pics:
Thanks!
