ᐅ Generating ideas for the layout of the bathroom on the upper floor

Hello everyone,
I am currently working on converting our attic space, but when it comes to the bathroom, especially the layout of the sanitary fittings, I’m a bit out of ideas.

Attached is the room sectioned off for the bathroom. There is a drywall knee wall at 1.1 m (3.6 feet), and the 2 m (6.6 feet) ceiling height is also indicated.

The wastewater, fresh water, and heating connections are located “top left” behind the drywall partition. Since I want to keep the floor construction relatively low, the drainage runs should be kept as short as possible accordingly.

I hope you can inspire me a bit 🙂

PS: There is already a large bathroom with a shower and bathtub on the ground floor.

What is supposed to go in there and for whom? ... how often is the bathroom used?

Regards, Yvonne

Good question, which I can’t answer yet. Either the children will move upstairs at some point, or we will.
Definitely a shower, washbasin, and toilet. A bathtub is not absolutely necessary, but I can imagine it would look quite nice under the double casement window.
Without a bathtub, I could also imagine having a small sauna, but I’m not sure if there is enough space for that.
