Sorry, I double posted by accident. Stress and sleep-deprivation. However, I have new info if anybody would care to advise. I just opened up the drywall a bit and saw that it is foil-backed. There is a small gap between that and the brick, which is lined with tar paper. Should I tear out the...

Planing on a CBU and Kerdi membrane shower in a new location. One of the shower walls is on an exterior wall (no plumbing). From the outside in, I’m pretty sure it's currently double brick, tar paper/slats, and drywall. We framed for a 3″ wall in front of the drywall to add some insulation...

Thanks again. But I'm still wondering if anybody has a firm word on whether to remove the drywall or not?

I thought Kerdi advised against vapour barrier between CBU and studs. Not sure if things change by making it thicker... or if leaving the drywall up is okay? I think contractor said something about leaving the drywall because there's an air cushion on the other side of the drywall at the slats.

Thanks. If I vapour barrier the inside, I would be worried about the "moisture sandwich" between that and the Kerdi membrane. I was guessing it would be less of a concern if it were on the other side of the insulation? Would it be better to just leave the drywall up and have it go brick-vapor...
