So I am about to undertake the last major project of my remodel this weekend, building a custom shower. It is essentially a 4x6 room with a shower head on each end, a bench and some storage nooks. Right now it is only framed.

I will be using the Schluter-Kerdi membrane and the Kerdi drain for the system. I will build a sloped mud deck, and have the tiles ready to go. I hope to be ready for tiles by the end of the weekend.

Do any you have any tips or tricks that you recommend for this job?

This is going over my dining room ceiling which is one of my favorite parts of the house, failure of the system is not an option.
