I installed a 32x32-feet inch shower pan. The shower has walls on three sides. I was planning to install glue-up plastic panels for the shower walls, but all the ones I can find at the big box stores are either shockingly expensive or won't fit.

So, I'm wondering if there's a generic type of material I could cut to size and install using construction adhesive. For instance, could I just buy 4x8-foot PVC sheets?

I know I could also do wall tile on cement board, but this is a rental property and I don't want to spend a lot of time and money.

  • There are many styles to choose from in FRP panels marlite.com/designer-wall-systems-frp-wall-panels.aspx. Big box stores usually only stock one style but it can be ordered in more attractive options

1 Answer 1


After having a number of shower walls deteriorate in just a few years, I paneled a stall shower with an underlayment of cement board and covered it with fiberglass reinforced plastic (FRP) wall board and corner molding (links are for reference purpose only).

The project cost less than US$100 and has held up for ~15 years. In fact, the shower base needs cosmetic touch-up, but the walls are fine, and water infiltration has been eliminated.

  • Thanks -- this is the answer I was hoping for. Follow up question: Is cement board underlayment specifically required, or did you choose to add it for additional water protection? (I guess I can do it either way -- it's cheap and will be fast to put up -- but I'm curious if the FRP manufacturers require it.) Jan 14, 2019 at 12:06
  • Cement board is usually a good idea in any potentially damp spot, and for the amount used around a stall shower, adds little expense. Previously, there was ordinary gypsum-based wallboard, which crumbled due to the humidity and leaks. FRP is actually waterproof, except at the joints, so it might be used over sheetrock.
