Primary concern is exactly what to possess as substrate ? Would it not be unique underneath the Kerdi than the rest of the floor ? Or, must The full floor get one/22 inch plywood and then kerdi on that and 1/2 backerboard for the rest ? 2nd issue is, for these a little shower, we're going to get kerdi board for the walls, after which new drywall will butt up in opposition to it on one particular wall ( was Wooden paneling). really should the substraight/backerboard go over the floor ahead of the drywall ? I'm sure Kerdi suggests with the shower stall alone To place the partitions in then the shower pan. But, if I want plywood 1st, wouldnt or not it's plywood, then walls, then shower pan ? Thanks
