ᐅ Partition Wall for Shower - How to Construct?

Hello everyone,

This is roughly how we want our bathroom to look.

Now the plumber needs the partition wall for the shower to prepare the plumbing.
How would you build this?
The plan was for a 10 cm (4 inch) thick wall and 2.3 m (7 ft 7 in) high.
The wall can only be fixed to the floor (concrete) and to one exterior wall (20 cm (8 inch) calcium silicate brick).
On this wall, as shown in the picture, the overhead shower will be mounted, with the mixer tap and hand shower mounted beside it.
Additionally, a recessed niche is planned next to the mixer tap, which I indicated with the red rectangle. This niche will be used for shower gel and similar items.

How would you implement this?

I don’t think a 10 cm (4 inch) wall is feasible. If I deduct 1.5 cm (0.6 inch) of tile thickness on each side, that leaves only about a 7 cm (3 inch) thick wall. That probably won’t provide enough rigidity, right? Also, the niche should have a depth of about 8 cm (3 inch), correct?
Oh, and a wall-mounted radiator has to be installed on the partition wall as well, on the side facing the room and towards the bathtub. That adds another 2 cm (0.8 inch) to the thickness on those sides.

Would you recommend masonry or a drywall construction for this?

Our walls are built with 11.5cm (4.5 inches) Ytong blocks and tiled on both sides, with a towel radiator attached. I consider the recessed area to be an unwise idea, as it is difficult or only very awkward to keep clean.

Ytong 11.5cm (4.5 inches) or drywall with a 10cm (4 inches) metal stud profile.
As a unit, a Wedi Sanwell niche in the appropriate size (if using Ytong, be sure to include a lintel above!).

@Nordlys Are soldiers complicated? Just wipe once with a cloth and that’s it.

@Domski Thanks for the tip. Have you installed these as well?

I would move the wall to the other side and use a glass partition, if only for the light. The shower will otherwise be a rather dark cave...

Hello

I would build it as follows:
The wall between the bathtub and the shower made of masonry, with the wall facing the room as a glass wall.
This brings light into the otherwise dark corner.
The built-in mixer with hand shower opposite the shower entrance,
so you don’t lose space in the shower area, the mixer is not directly exposed to water and shower gel, and you don’t get wet immediately when turning on the shower.
