Richard that is beautiful.. ! You have given me the courage to tell my (shorter) story. I found the perfect shower at HomeLowes and spent hours building a circular base to support the fiberglass shower base. Only then did I realize it was too high to fit!!!!! I returned that one and bought a cheap neo-angle shower kit that will fit until I have the time and funds to do something nicer. The shower I have is a poly material. I was concerned about movement between the inner shower wall ( the east-west wall if the coach is pointed north-south) and the wall that mounts to the outside wall of the coach since there is a seam there on this shower surround. I devised a way to mount an inner plywood wall that is bonded to the inner ( east-west) wall and "floats" beside the outer wall. I'm curious if you see that as a problem? Did you fiberglass that inside corner on your installation?
