Bathroom planning knee wall 1.00m roof pitch 45°

Hello everyone,

I took some time to think about our bathroom and played around a bit with an online planner.
My main concern is the layout. The furniture pieces that belong in a bathroom are not so easy to implement there.
But I imagine a double washbasin with 2x2 drawers underneath that complete the whole thing and hang on the wall, so the floor remains free.
Between the toilet and bathtub, I would have a shelf built, either tiled or made of laminate panels with waterproof bonding. You could put sliding doors in front of it or work with baskets.
Knee wall 1.00m, roof pitch 45°.
As I said, I would appreciate feedback regarding the room layout.
The window will either be frosted glass or divided, with the lower part fixed with frosted or satin glass.
What I would be interested in is the window hinge, left/right, which is more sensible?
Shower door hinge left/right, which is more sensible? Does it make sense to make a part fixed in order to have, for example, a smaller swing area? For example, 20 cm fixed, 80 cm door?
Do you need a towel radiator in such a small room if underfloor heating is installed otherwise?
Or would you plan everything completely differently?
Thanks in advance.

I would place the bathtub and toilet just below the 2-meter line. It looks more elegant.

Find it okay. Which software is that?

What exactly do you mean?
The toilet and bathtub end at the 2-meter line and there is no more bevel?
So also a straight bathtub? We liked the option to take a wider one so that two people can sit next to each other once in a while; we thought max. width 1350.
I'm also considering the toilet because then you could nicely integrate a shelf in between.

So I go to the bathroom in the morning, stand half asleep under the shower, and gradually wake up. Then I reach from the shower for my towel... oh where is my towel? Oh, it’s still hanging on the other side of the bathroom on the radiator... :(

What exactly do you mean by that?
The toilet and bathtub end at the 2-meter line and there is no more sloping?

Yes, that's what I mean.
Square shower, reduced washbasin cabinets, and then an asymmetrical tub in one corner, and in the other corner an angled toilet.
My opinion: too much cramped into the corner, too arbitrary and mismatched in shapes. I would also do without the mentioned shelf. It could all become very restless!
