Procedure for basement wall - shower

[mazz]

Hello
I have a laundry room in the basement where the plaster on one wall (which is an exterior wall, i.e., the house's foundation) is coming off in some places. I have started tiling the walls, but only an interior wall so far, which was stable and solid.
The affected wall is to be tiled, and a shower will be installed in the corner.
What steps should I take here?
Moisture barriers against exterior walls in the basement - they shouldn't be installed, right?
Is it enough to knock off the loose plaster and then either fill to a smooth surface or let the tile adhesive solve the irregularities?
The exterior walls are made of masonry blocks and the house is since '46.

Is it enough to knock off the loose plaster and then either fill to an even surface or let the tile adhesive solve the unevenness?
The exterior walls are masonry blocks and the house is from '46.

My house is the same age. Same problem and I tiled the entire laundry room.
Knocked off all loose plaster. Washed with a high-pressure washer, rotating jet nozzle. Repaired all places where the plaster was gone with plaster mortar and then tiled. Has worked perfectly fine.

It is usually recommended to have a moisture barrier in the shower area itself and a bit to the side, but not in the rest of the bathroom when there is an uninsulated concrete slab.

We have a similar situation and we will probably choose to install a shower cabin to avoid the risk of problems with the waterproofing and uninsulated concrete walls/floors.

What could it become in an uninsulated basement with concrete floor and walls in an old house?
Shower cabin is the devil's invention and a hell to keep clean.

Hi,
We had a similar situation in our house from -23.
Loose plaster and concrete were knocked off, wall and floor were repaired with lime plaster and concrete/self-leveling compound respectively.
A diffusion-open waterproof membrane was applied on the floor, slightly larger than the shower area, and about 10cm up the wall.
Then tiles and tile floor.
