Thank you for your feedback.
Regarding usage: the bathroom will mainly be used by 2 adults, however as the main bathroom. One floor below there is another small bathroom for our child and guests.
We are unsure whether the wastewater will work with the toilet and the window as it is, or whether we want a toilet directly in front of the window (yes, of course you can cover this a lot with blinds or something similar).
With the proposal of the toilet next to the shower, the headroom standing in front of the toilet would be limited, the slope here is about 1.60m, the entrance to the shower is not affected.
The old bathroom has now been dismantled to the extent that we will both stick both options simply on the floor to get a better spatial feeling, also regarding freedom of movement.
