I have roughed in a shower so that I will put wall board behind the acrylic shower walls as opposed to attaching the shower walls directly to the studs. I believe this will add stability.
Would it make more sense to use cement board vs greenboard behing the shower walls since I will need to drill a hole for the shower valve and a hole for the shower arm thereby potentially not exposing gypsum to H2O?
This way if water ever leaked behind the acrylic shower wall surround, it would not damage greenboard. So you'd have stud/cement board/acrylic shower surround/and then greenboard over the flange of the shower wall.
An alternative idea I have is to use greenboard, but just leave a gap between the studs where the valve is located behind the shower surround. In this case, I wouldn't need to drill any holes since there would be no drywall covering the valve. It would look like: stud/greenboard/surround/greenboard over the sourround flange.
Thanks for your opions.
