What’s the first step?
Well, if you haven’t done demo, that’s a great place to begin.
But ideally you should also have a plan for the new bathroom and shower. One demo is complete, you should inspect the mechanicals. For example, look at the subfloor, studs, electrical, and plumbing.
Schluter has specific requirements (as do all manufacturers) for subfloors. For example, since our joist spacing was 16″ o.c., we used 3/4″ plywood for the subfloor. Read Schluter’s handbook and see what they recommend for the subfloor.
Also, stud spacing should be 16″ o.c. for any backer board, including drywall. By the way, did you know Schluter recommends using drywall for KERDI shower kits? Yep, it’s due to drywall having a flat surface and the fact that KERDI will completely waterproof the paper face of drywall.
Check studs with a 4 foot level; they should plumb and even with each other. That way the backer board, in this case it’s drywall, won’t bow in or out.
If any electrical runs behind the shower now is the time to inspect, reroute, or replace it. Once the shower is built, electrical will be a pain to move.
Finally, get your plumbing in place before buying the shower kit. And determine if you need to reroute the drain. If you’re not comfortable doing this yourself, call a qualified plumber and make sure they know what shower system you’re using. That way they don’t have any excuse when the drain doesn’t line up with the shower pan, which happens all the time with contractors.
