Bathroom floor plan design - How to place the windows?

Looks like a corner bathtub?

Oh, I see. Sorry for the slow response.

That can happen sometimes ;). I also needed a moment at first glance. I was about to write that the tub at the T is drawn too narrow ;).

Then I tend to prefer option 1. However, max. 1 wall partition for the WC, otherwise airy, free and open. :)

Thanks already for your answers. We are still at the very beginning of the planning phase, i.e. the location of the sewage pipes is still open. The plan was created by us ourselves, the architect’s is currently in progress. In the 2nd draft, the triangle is supposed to be a corner bathtub. :-) but if it extends further into the room, it will be a bit tight...

Really? - Is it going to be a bungalow? - otherwise it would be helpful to know what is located on the floor below.
