Distance from shower cabin to ceiling

The front edge of a toilet should be at a height of at least 2 meters. Perhaps the skylight helps here?

I have moved the toilet exactly up to that point. A bit further to the left is also possible. The skylight doesn't help, it's too far away. It is definitely possible if you really want to, even with a bathtub.

Thanks for the feedback! I'll see if I can still include the toilet issue. The shower cabin definitely not 200cm high, but "only" 180cm or would 190cm also be acceptable?

I am of the opinion that 2m also work, as I said, because afterwards you can leave the door open to dry. During the shower, I would say no ventilation is needed.
