A couple people asked me to upload a cross section view of the tile, backerboard, waterproofing membrane, etc. Rather than try to reinvent the wheel, I figured I’d post some useful references that I used throughout the process. First of all I’d like to say that I’d recommend going with a thinbed installation method. The old school way is to have a thick vinyl-like product (Chloraloy is one option) underneath a thick bed of “deck mud.” For a variety of reasons I chose to go with a thinbed installation instead and would suggest the same for anyone else. The thinbed route means either using a sheet membrane (NobleSeal, Kerdi, etc.) or a liquid membrane (RedGard, Hydroban, etc.). We went with Kerdi, but the prep is essentially the same regardless of what you choose.
Hopefully these links will help you in figuring out how to build and tile your shower.
If there is a demand for it I’ll go over the various options for waterproofing (Kerdi, Nobleseal, RedGard, Wedi, Hydroban, etc.).
