Shower by the window? Do you really want to always wipe down the windows after showering?
In the end, we decided against a continuous wall and door between the bathroom and dressing room (for reasons other than those mentioned here), that might also be an idea here? I don’t quite remember right now, is a controlled residential ventilation system planned? Then the moisture won’t be a problem.
And if the door to the bathroom is removed, you have more options in the bathroom.
Personally, I don’t find a bathtub in front of the shower bad at all, it can work quite well:
The shower is located at the back right here.
Would that also be an option for you?
