green board VS durock

[jdawg]

Inside a stand up shower, using a shower surround ( 3 wall section shower stall) and I am not tiling above the shower stall, should I use green board or cement board(durock) inside the shower area?
Above the shower stall I am just going to paint...not sure if this makes a difference as to what I use for the walls?

Use the cement board. Cheap insurance in case you get a little moisture behind the surround. You can transition to drywall above the surround, or I have even skim coated Hardibacker where it has come out past the tile.

the shower surround gets nailed right to the studs so there is not need to put any cement board or Drywall behind that, it would just be from the lip of the shower surround to the ceiling. so I think I'll just use the Green Board for the whole bath and be done with it, and take the Durock back. save me 50 bucks...thanks !

Green board is not to be used in wet locations for about three years ago...... granted, this may not be a wet location.
Not over a vapor barrier....IRC [702.4.3
All cut and exposed edges must be sealed with water-resistant sealer.... [702.4.3]
Not on ceilings with >12" o.c. framing....[702.4.2]
Finish to extend minimum 72inches above drain... [307.2]
Why take the chance?
Be safe, Gary
