I'm about to start a bathroom project which involves fixing shower mixer valves into a solid brick external wall.
I'll be putting 25mm insulation on the wall + 12mm tile backer board + Tiles/adhesive.
The mixers are 70mm deep so will project back into the wall. There will also be a number of pipes set into the insulation/wall.

25mm is the thickest insulation I have room for on the wall as a whole but I could chase the wall at the back of the mixer further if that helped.
Question is, am I going to have condensation/mould problems and should I be doing it differently?
