New construction bathroom floor plan upper floor - feedback?

Worked on a t wall again.

I tinkered again with a T-wall.

Why? Because a T-wall is currently in?

Edit: this isn't the granny flat, is it?
Please don't get confused, but stay on topic.

Otherwise: slalom skiing, so that one has a perspective never seen again (except in a plan from above), has no advantages. There's absolutely no order in it.

Tinkered again on a T wall.

When it comes to screws, they say, "after tight comes broken," meaning: you shouldn't keep turning. Builders who have reached their goal should be tied up like Troubadix.

I would like to place the bathtub by the window.

I am still considering how to build in the bathtub at a window sill height of 80cm so that you have an unrestricted view outside while bathing.

I think a pedestal under the tub already gets you to the right height. But you look at the window frame when you are inside. So does that really only work with floor-to-ceiling windows?
