Hi everyone wow what a great website and discussion forum. Lots of info. I am hopefully
going to install one of Schluter shower kits. I have watched the video and everything seems pretty much idiot proof but i am a little unsure about the plumbing drain about location . Height
to subfloor. I have done a search and really havent found anything to do with specifics with drain location.

Try here.
Kerdi Showers

Kerdi shower kits normally come with the drain in the center of the base except for the optional 32" x 5' kit which comes in the center or at the end.
