I am going to build an internal wall in a space that was created when I removed a built-in shelf. The wall is constructed with two "pillars"/studs that support the ceiling, then a layer of tongue and groove wood and finally some OSB-like board:
The hole is about 200cm x 90cm with tongue and groove + OSB, and then the pillars continue 67cm up:
I am planning to make a bathroom in front of this, with a wall-mounted WC against this wall.
The thicknesses are "OSB" 15mm, tongue and groove 22mm, stud 50mm, totaling 91mm (due to a bit of hollow space).
My plan is to place the studs roughly as shown in the picture above, but at the outer edges, and then install about 3 plasterboards (NORGIPS NORMAL 13X900X2000MM) which would be 39mm thick + 45mm stud = 84mm, and then potentially add a spacer for the last 6mm in the other direction.
The questions then are how to level the plasterboards against the existing wall on the far side; I recall there being some adhesive tape you can apply and then plaster over?
How should one think about reinforcing the studs for a wall-mounted WC? Would regular 45mm metal studs for interior walls work or should I use 45x95mm wood "for support"? Does it depend on each individual WC regarding the measurements? Then it will need OSB and moisture-resistant plaster against the bathroom.
You need to have 45*95 with the short side towards the toilet to handle the breaking forces. Check the installation instructions for the toilet. Transverse studs will probably need to be installed as well.
The main thing is that the wall you build is not wider than the existing one. If there are no pre-made studs in the correct dimension, you can split your own. Also, insert OSB/plywood between the studs and then a layer of OSB/plywood over that and finally the wet room board. Then you have 2 layers of wood board where the wall-mounted toilet will sit.
Yes, I am unsure since it is my first time building an inner wall, and this feels like a special case.
If you have a better alternative, I'd love to hear it!
The right opening in the picture is a door and should remain, while the left one should be closed.

If 95-studs are required on the short side for a wall-hung toilet, then it will have to be floor-mounted instead.
There is not a lot of room to play with, actually.

Was thinking something along those lines and insulation between the recessed OSB and the boards on the other side, but that wouldn't hold, right?
