Planning a 12 sqm bathroom sensibly

I would probably go with my second option. However, the bathtub should be placed directly under the window, so that those annoying dead corners are eliminated, which serve no purpose other than causing trouble when cleaning because you can't reach properly.

Can the bathtub be placed opposite the door? Then there would still be 90cm of space to walk through with an 80cm wide bathtub (if all the installations fit into the wall to the children's bathroom), that should be enough, right? Move the washbasin a bit upwards towards the window, the shower wall can then be longer. But how long is the wall opposite the door?

Thank you very much! The tub should not be freestanding precisely because of the dirty corners. Unfortunately, this is not yet included in the plan. Either a straight tub, which would be my favorite anyway (then 1.80x80 or 190x90), or a tub built into the corner, depending on the space.

Unfortunately, I thought the same when I saw the overall floor plan.

That's true, nothing more should be removed there. If the door from the bedroom to the hallway were omitted, one could possibly even widen the dressing area a bit, since we have a 1.60 wide bed anyway and not a 2 m bed. I find the idea of omitting this door quite charming!

The wall opposite the door should be 1.37 m long.
