I have torn out the tiles and drywall on walls surrounding a tub/shower area. I found that the studs are not plumb and on plane, a requirement for installing cement backer board. My question is, how much variation is acceptable? There are three walls and a ceiling. The two end walls are about 33" wide and 68" high. The back wall is about 58" wide and 68" high. The back wall has a window in it, about 48" wide and 36" high. It is centered and the top is flush with the ceiling. For these widths and heights, about how much can you ignore? I am a complete novice, so please don't assume I know anything! Thank you.
