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:

We do it somtimes, but you will need to go with option D, sorry. http://i76.photobucket.com/albums/j3...r/DSCF0489.jpg

 

John,

I disagree for the need of a CBU on the ceiling of this shower.

You can do;

A) Leave as is as.
or
C) Tile over existing drywall, with or without liquid membrane.

If you simply paint it, I recommend using a paint made for this purpose. Use Perma-White by Zinsser. Mold Mildew Resistant Paint - PERMA-WHITE Mildew-Proof* Bathroom Paint

my shower is just green board painted with regular paint. no issues that i know of. but only 2 showers a day.

great looking shower. is that a water proof light ?

 

No need to change out the drywall and no reason to Redgard it. You can tile directly over it. Make sure the drywall is properly fastened to the ceiling joists. A few more screws is a good idea. Do to how low that ceiling is, I'd think twice about the paint option. That ceiling may receive a little more spray than you anticipate.

 

Once you get mold you'll have to dig deep and start over. Option "D" requires more work for sure. But would have longevity. Do it right the 1st time and sleep well.

 

You typically do not have mold issues on the ceiling, or above the sprayer where water does not directly contact it. I've had drywall for my ceiling for ever and not a problem.

I say, if the ceiling is already down, and you happen to have leftover CBU, then sure, why not, but I would not tear out a drywall ceiling just to install CBU.

 

Condo-owner, it is a fan/light combination, believe it or not! Regular square box installation in the joists with the cover. The inlets are above the light. Neat, huh? Expensive, yeah.

 

hmmm. i would be worried about shock and rust. my master has that type. but not IN the shower.
