what is the best shower pan installation
I a general contractor, and I am building a new shower (in my own place). I was hoping that you could give me your opinion for what you would consider the best method or product to build a shower pan with a curb. I have not chosen my products yet so I can build it any way.
I hate to show my age but the last time I built one I lined it with lead and mortar.
My tile setter recommended using a Wedi shower pan but I'm not convinced. On the walls the Wedi seems flimsy. I was considering using Denshield. For shower surrounds I usually use cement board with red guard
Best Drain for shower pan
If you are using little tiles like these 2"x2" tile then a little forgiveness is nice. The Kerdi drain allows some wiggle room at install time. This is small barrier free shower system in Vancouver and was prepared using a hybrid approach of Ardex 8+9 and Kerdi.
If you contact Ardex you can get a ten year warranty system with this approach. Twice the warranty that Schluter or Kerdi give out by themselves. And the kicker is you can use better thin-sets!
Best strength in shower pan liners
On a busy job site with multiple trades everywhere the "Best" Shower pan liner is this stuff. Noble Seal TS or Noble Seal SIS. 30 mil thick (thickness of your bank card) and bondable to the substrate and tillable if set over a proper substrate.
With multiple niches and a floating bench I prefer liquid or cementious membranes. So heavy protection down low and ease of application up high. Lapping the second over the first (not shown in this picture) is key to success and should happen above the height of the curb.
As with all our projects this shower was flood tested and inspected by a Vancouver Plumbing Inspector.
