While we mainly post final pictures of our installs, I think its time to start addressing some techniques for constructing a proper shower. Over the years we have seen many people use the "water in water out" PVC pan liner system. While we agree that this method has stood the test of time, it also requires proper installation methods.
The first step is proper rough in with a 3 piece drain, which requires a pre-slope before the pan liner is installed. The beveled edge of a 3 piece drain sets the guage for your mud bed pre-slope. Typically, PT 2x4s are used for the curb while the PVC liner laps over this 2x4 curb ONLY using nails (roofing nails) on the outside to fasten the liner. The curb is then covered with a wire lathe NOT SCREWED CEMENT BOARD!!! and then troweled with mortar, and then a final smooth coat (allow scratch coat to cure).
