Brainstorming ideas for the floor plan of the bathroom on the upper floor

Hello everyone,
I am currently working on the conversion of our attic, but when it comes to the bathroom, especially the arrangement of the sanitary fixtures, I am somehow without ideas.

Attached is the room now sectioned off for the bathroom, there is a dry construction knee wall of 1.1m, the 2m height is also marked.

Dirt, fresh water, heating are located "top left" behind the drywall. Since I want to keep the floor structure relatively low, the wastewater routes should be kept correspondingly short.

I hope you can inspire me a bit :)

PS: A large bathroom with shower + tub is already located on the ground floor

What should go in for whom? ... how often is the bathroom used?


Regards, Yvonne

Good question, which I cannot answer yet.. Either the children will move upstairs, or we will. Shower definitely, washbasin, toilet. A bathtub is not an absolute must, but I imagine it would be quite nice under the double casement window. Without a bathtub, I could also imagine a small sauna, but I don't know if there is enough space for it..
