I have purchased a Sterling Accord 4 piece tub/shower surround. I have 60-1/4" rough in space for the 60" tub/shower surround. It says that I can nail directly to studs, but I have had a few people tell me I should try to get concrete board or green board behind it before I install, what are your expert opinions? I know I have the depth to install green board behind the surround, but I don't think it will fit if I install backer board on the ends.
Is it really caulkless? Do the seams seal tight enough to preven moisture from getting behind the acrylic surround? Can I get away with just installing the surround to the studs?
Thank you in advance.
