I have a few questions concerning bathroom wallboards.
1. Not including a shower wallboard, what type of wallboard is recommended to use for the remainder of the bathroom walls and ceiling? I've read mixed opinions including regular drywall, greenboard, and some kind of mold and mildew resistant board. This is in a basement of a house in the northern US if that matters.
2. Odd problem. We're using a fiberglass pre-made shower basin (60" x 30") and tiling the walls. When in place there is just under a half inch gap between the basin and the wall. The room seems to measure 5' 1/2" wide. From what I have read it's recommended to place the wallboard over the lip of the basin, but that leaves a 1/2" gap between the wallboard and the wall. Is there a recommendation on how to solve this issue? We thought of installing a 1/2" piece of plywood to fill the gap however that will leave a protrusion where the shower ends and the bathroom begins. Another thought was to install the wallboard behind it, but then it doesn't come over the lip of the basin.
Any advice is appreciated... thanks!
