Position of the bathtub under a sloping roof

Thank you! But is the middle of the tub below the 2m line?

For us, the distance and thus the "space waste" between the tub and the knee wall would be about one meter. I think that's already quite a lot.

Yes, referring to the visible beams. But note that your roof is steeper! The 1m line is about 1/3 of the installation area away from the wall.

We have placed the bathtub directly under the sloping roof (just under 1.1m knee wall), but we set the bathtub on the raw floor (of course sealed accordingly). This makes the bathtub sit lower and provides more headroom under the sloping roof. Additionally, we have a large skylight above the bathtub which also provides extra headroom. We find this to be a well-solved and comfortable arrangement and have no problems with it. Here is a picture:

Thank you all! But at your place Dindin, the roof window will surely be ripped out, right? What roof pitch do you have?

We have a roof pitch of 35°.

OK thanks. Do you think I could dare to move the bathtub 30 cm towards the knee wall?
