I want to renovate a bathroom, but I have the problem that there are two exterior walls made only of 24cm (9.5 inches) brick without any additional insulation. Actually, this means just one wall, as in front of the other there is an 8cm (3 inch) Styrofoam insulation facade.
The walls were originally covered on the inside with fiberboard panels. I have now removed these and am left with two uneven, slanted walls.
What would be the smartest way to get nice, straight walls that I can tile up to roughly three-quarters of the height?
Would it be best to simply install a lightweight drywall (green drywall board) in front? Should this be done with ventilation space only, or with insulation and a vapor barrier? If insulation, which type would you recommend?
Or maybe just put up a 7cm (2.75 inch) aerated concrete block wall with a 2cm (0.8 inch) air gap in front?
Or just apply a lime plaster?
Or... or... or?
Additionally, the bathroom is only used occasionally since we have another one. It is therefore only minimally heated, and a condensation dryer will also be placed in there, so it's really an ideal setting for mold.
I would appreciate any good advice.
Best regards,

if the bathroom is not used frequently and there is also moisture from a dryer, I would recommend using calcium silicate boards. These can absorb and release moisture and are best suited for preventing mold.

Since it fits so well right now:
Is it possible to install the panels directly onto the plaster (by gluing or screwing?) and then wallpaper and paint over them?
In our case, there are tiles from the floor up to 30cm (12 inches) below the ceiling, and above that, it is starting to turn gray...
However, the exterior wall is insulated (blown-in insulation)...

Hello,
There could be several reasons for this. Excessive humidity and/or insufficient surface temperature of the building element. It is also possible that a thermal bridge is present. It is not uncommon for blown-in insulation to result in an uneven distribution of the insulation material.
