We have made a new entrance to the house where we built a basement with a slab on the ground. The idea is that the space, which is about 6m2, will be used as a bathroom and is now prepared with underfloor heating and drainage. When we planned it, I said that we want pipes installed within the walls, and since these are exterior walls, we said that an installation wall should be built outside the insulation blocks where the water pipes would go.
I've been wondering if it was right to plan it this way. Could there be problems if I construct with metal studs and screw plywood/gypsum so that there is a void between the insulation blocks and the future interior wall? The basement wall is drained and insulated, so there won't be a frost risk, but I'm more concerned about the risk of moisture problems if it becomes an enclosed space.
An alternative now is to run external piping, but then the drainage for the toilet and shower floor drain is unfortunately placed unnecessarily far from the wall.

As long as you have good ventilation with exhaust in the bathroom, there shouldn't be any major problems. You will get an air gap with the metal stud. If you are still worried about possible moisture, use some other board on the wall that isn't organic.B Baskavoda said:
Yes exactly, it might be smart to use two layers of minerit or similar instead of plyfa+gips
