Connection of bathtub to shower

If you have a 1.55m knee wall (shown at the top of the picture), then you cannot place a shower there.

Exactly 1.55 m is the knee wall height with a roof pitch of 45°

I would make the shower bigger and have glass all around, I wouldn’t build a wall in the small room. Possibly a mix of making the shower bigger and adding a shelf area for the bathtub.

No space for the bathrobes :D but yeah, I think hbf is somehow right - otherwise you always have some grimy little corner there.

So we are also currently choosing the sanitary fixtures and the design of the bathrooms. I can tell you, aside from the shower door, no glass will come into the kids' bathroom. Easier to maintain! ;) So I would build walls and a shelf area for the tub.

Who cleans the glass in the children's bathroom?
