There are plenty of Kerdi shower projects described on the forum, but if you want to go to the source, go to www.schluter.com
. Once you get their home page, click on Products, then shower systems. You can play some videos there that show how the installation goes.
For a non-skid shower floor, use fairly small tiles. 2"X2" is pretty typical. The grout lines give your feet something to grab onto. For extra insurance, find an ADA rated tile. These have a built in non skid surface.
I've just finished a shower that has it's own vent and really like it. What worked for me was a remote vent fan made by Fantec which not only allowed installation of a vent in a wet area, but also services two others in the bathroom: one in the main bath and another over the toilet. A vent in the shower keeps the fog out of the main bath and your mirrors and also helps to dry the shower out. Put the fan on a timer and couple its operation with a shower light (rated for wet areas).
I've also heated my shower floor and bench with low voltage electric heat under everything and wouldn't live without it now. Mine was made by warmfloors and is a conductive plastic, but there are other low voltage solutions out there (24V).
If you want to do a Kerdi shower, you must do a Kerdi drain, so plan for that before you proceed very far or you'll be ripping stuff out.
