Bathroom planning - idea search for bathtub placement

Hello everyone,

we are planning our single-family house and are now in the detailed planning phase regarding our bathroom on the upper floor. The bathroom has a sloping roof (south side). We would like an open shower without a door and would like to have two sinks. We are unsure whether a freestanding bathtub looks good given the small bathroom size of about 13m2. Attached are the official planning status as well as my reconstruction in SweetHome 3D.

Do you have any suggestions or ideas regarding the bathtub? I am not 100% happy with the toilet behind the door, but my better half would like it that way.

A bit more of the building would be helpful. (So the whole thing including the ground floor) Also the knee wall height and roof pitch, meaning the 2-meter line, would be important.

And room width 408 cm does not seem to be correct, because the original plan says something about 388 cm. And, it also looks like the measurements of the wall section, then the door on the right side are not correct.

In case it helps you: we have planned almost the same for a similar size... However, the slope is on the other side. The 2m line shifts about 15cm towards the roof because the roof will have a slightly different construction.
