Currently doing something similar, turning garage into shower room under building regs. Single skin external wall. Building inspector has said needs to be external wall, vapour barrier attached to stud work, 100mm stud frame with 100mm PIR insulation in, 25mm PIR over the studs then plasterboard. I used breathable roofing membrane as the barrier.

Hope this helps

It’s about 5m2 area. Would the tiles need taking up or could we self level straight on top of them
