What are the options for wall covering leading to the fiberglass shower surround? The transition from sheetrock to the fiberglass shower is my biggest concern. I am also curious if tiling the 12" from the top of shower wall to ceiling is typical.

Hi BR

Typical is to prime/paint the area above the surround with a mildew-resistant primer/paint. It is quite rare that anyone tiles this space.

Why the concern here? Mold, mildew, etc.? If this is the case you should probably consider installing an exhaust fan... ;)

Back to you...
