I would generally also advise against black. It has to be cleaned constantly, even if it looks very elegant. What works well is if you have an open shower. Then the whole bathroom can simply be aired out :) friends of ours have that. If you like it, it’s great :)
We finally have a final plan now The bathtub has now been placed under the window, the toilet planned next to the shower, and the bidet completely removed! ☺️ The plumber started yesterday EveundGerd, thanks again for the valuable tip!
