ᐅ Bathroom Layout Planning – How to Position the Windows?

Hello everyone,
we are currently planning the bathroom layout and would like to hear your opinions.
The bathroom measures 4.20 m by 3.30 m (14 ft by 11 ft) and is located in the northwest corner of the house. The door position is fixed because the staircase is along the remaining wall. The window placement is still open.
It is important for us to have a walk-in shower without a door and a 1.60 m wide (5 ft 3 in) vanity unit (two sinks, each 50 cm (20 inches) wide, with 20 cm (8 inches) spacing between them and 20 cm (8 inches) on each side). A somewhat hidden toilet behind a half-height wall would be nice. The bathtub doesn’t need to be special. (The washing machine will be placed in the utility room on the ground floor.) There should also be some space for a radiator or additional storage somewhere.
Attached you will find our two favorites. What do you think? How would you suggest positioning the windows? Do you have any completely different ideas?
Thanks and best regards

Hmm... a full storey, so without a sloped roof? And where would you place the windows?

Yes, a full floor, so no sloping roof.
We have considered installing one window on the north side and one on the west side. The window size/dimensions, whether to use clear or textured glass, and whether the windows should be operable or fixed elements are still undecided...
We might also want to add a fixed glass element in the interior wall/by the staircase. This would bring in more light and create an eye-catching feature ;-). (1.75 m (5 ft 9 in) above floor level, 1.50 m (4 ft 11 in) wide, and 0.40 m (1 ft 4 in) high)

I would probably arrange it in a traditional layout or with an L-shape.
Where is the wastewater pipe planned, or is that still undecided? What stage of planning are you currently in?

I don’t understand right now: what is that slope supposed to be in the second draft?

@kaho674 ... probably a corner bathtub 😉, which would typically extend further into the room.
