A shower pan, comprising:
- a first preformed portion having a drain hole and a bottom flat surface to contact a floor and a top surface having a predetermined slope toward the drain hole;
- and
- a non-compressible second preformed portion coupled to the first portion at the drain hole, the second portion having a bottom surface with the predetermined slope to gaplessly fit with the first portion through a waterproofing pan liner, wherein tiles are subsequently mounted on the non-compressible second portion.
A method for building a shower, comprising:
- forming a shower subfloor with a flat surface to support a first preformed pan module;
- placing the first preformed pan module with a first flat surface facing the subfloor flat surface, the first preformed pan module having a first sloped surface toward a drain hole;
- placing a non-compressible second preformed pan module above the first preformed pan module with a shower pan liner in between for waterproofing, the second preformed module having a first surface to engage the first sloped surface with the liner and an upper sloped surface;
- and
- installing tiles on the upper sloped surface of the second preformed pan module.
