Bathroom renovation floor plan - tips?

Hello everyone,

we are currently planning the renovation of the old building bathroom. We have given a lot of thought to the floor plan, but have little experience. It would be great if some of you have valuable tips for us before the renovation begins. Maybe with your trained eye, you can also directly spot problems or ideas for improvement in our current draft.

Many thanks!!!

Comments on the floor plan:

1. Shower (100 x 160) and toilet will be installed on a partition wall. There are some surface-mounted pipes there. The shower tray will be enclosed with glass. A fixed element at the top of the plan. The right wall will have a fixed element at the bottom and a hinged door at the top.
2. The whirlpool bathtub (80 x 180) is partially (blue frame) under a sloping ceiling, which is quite high. Bathtub and toilet should be separated by a new small wall, which is as high as the bathtub. Above the bathtub it will be flush with the wall.
3. A new pipe will be laid for the washbasin cabinet (120 wide). The window opens inward.
4. A radiator will be mounted below the window.
5. One or more 1.2m wide tall cabinets should be hung under the washbasin.
6. The red box marks the position of the gas floor heating.

Looks okay.

under a slope, which is quite high though.

Can you also stand at the washbasin underneath?

Bathtub and toilet are to be separated by a new, small wall that is as high as the bathtub. Above the bathtub it finishes flush with the wall.

Let this wall continue behind the tub – that’s called a pedestal and is intended as a shelf. Be careful with the faucet so that the water flows into the tub.
The shower drain should point towards the wall, right?

Looks fine. Can you also stand at the washbasin underneath? Let this wall run along behind the tub – that’s called a pedestal and is intended as a shelf. Be careful with the faucet so that the water flows into the tub. The shower drain should be towards the wall, right?

Thanks! You can’t install a washbasin on the upper wall. The height at the upper wall inside the blue rectangle is about 120 cm. We imagined the water supply for the bathtub on the left wall, but unfortunately that’s drawn incorrectly. I’m not sure about the shower drain. Either on the left wall or on the lower wall. Which would be better here?
