New construction bathroom floor plan upper floor - feedback?

I think it's very nice except for the dark shower, I always prefer glass, at least the upper half. But that conflicts with your towel holder - only one of the two can work.

I would attach the shower wall to the room wall at the bottom of the plan and make the partition wall at the bathtub only about 1.60 meters high, for example. It goes without saying that the fitting must be on the room wall, so the low partition wall "up there," i.e., above 1.60 meters, has no contact points with water. Then moisture extraction and natural light would be ensured. Instead of 1.60, you could also use the height of the shelf on the right side of the plan, e.g., 1.30. If the shower reaches 2 meters in length, the height is completely sufficient [emoji4]

2m would not be reachable because of the passage. Max. 130cm. This way it could also be designed.

Although it looked more harmonious before.

Huh? The proportions should be about ~2 meters at #18?!

The latter is a complete waste of space in the room, while the shower is smaller.

The wall is 488 - 85 WC - 180 bathtub - 75 passage - 12 partition = 136 cm.

Could also integrate a glass partition on the homepage.
