Bathroom layout

Good evening everyone, I am currently planning our bathroom. The bathroom measures 3.72m x 2.87m. Attached is a rough sketch of my first idea. Maybe some of you have other good ideas? I would be happy :)

Draw once more so that one square measures 50cm, then you will immediately notice that the space at the WC becomes too tight.

This will be tight. You need 1m for the toilet, the double washbasin is 1.20m, and then you still want to get into the shower, possibly hang towels somewhere near the entrance to the shower.

I also don't find the door opening towards the toilet optimal. I would lower the door and change the hinge so that it opens towards the bathtub.
Because of the low-placed window, you take away the only space for a piece of furniture.

Please also draw a door to scale (one meter wide) ;)

New or old building?
Still in planning or are the walls already standing?

What is movable?

For one person or for five?
Accessible or not?

And where should the door be? On the short or long side?

Hello dear ones,
thank you. You are absolutely right, with my improvised drawing you can't do much. Attached I am sending you the floor plan with exact details.

Please note, it is a house from the developer (so a new build), nothing can be changed about the window position (it is floor-to-ceiling) because otherwise it would not fit into the overall concept.

I am looking for a nice solution that is not too expensive. I would be very happy to receive various floor plan suggestions. I find it nice if different areas could be created, e.g. for the shower and the toilet.
