Optimize bathroom layout

We have also thought about it again... Draft attached.
Partition at the toilet only half-high.
What are your opinions? What disadvantages are there?
Possibly toilet too close to bathtub?
Laundry chute inconvenient, as the lid is in a potential wet area?

The biggest drawback in my opinion is the missing window on the right side of the plan. Also, you enter and immediately run into a wall. It's all not very smooth. Here is this one as well:

Possibly like this, if it should be a bit smaller.

Or something like 4.00 m * 2.53 m.



WA also fits next to the sink under the window

The windows are not fixed yet.

well, however, the facade is influenced by window positions. That is why I do not think much of single-bathroom discussions. If a shaft is “set” in the upper left, then it should also be permitted in the upper right?! Because it already structures the design through its depth/width. So it actually only makes sense to integrate it into the pedestals of the tub and to use the depth on the outer wall and then position the washbasin there. The lower part of the plan then remains as the planner envisions it - in my eyes very sensible.

Another good example where the OP has to learn that in a bathroom with a depth of only 2.50m and a total size under 10sqm, wishes such as a 190x90 bathtub + WalkIn shower cannot be satisfactorily accommodated. The best design is in my opinion still the one by the architect without any additional space gains in the bedroom.
