Optimization of floor plan and bathroom planning with sloped roof

I would do it that way, but also with a glass shower partition. It’s no use otherwise. A proper walk-in shower hardly fits in a standard bathroom with a sloping roof. This gives the children's room a fixed wardrobe niche of about 150, plus space for a light switch at the door. [ATTACH alt="Bildschirmfoto 2025-09-05 um 12.26.47.png"]92807[/ATTACH]

I have pushed the bathtub forward a bit for easier access.

It could be done like this or like that:

Hello @11ant Your answer somewhat misses the point of the question. The question is not what the draftsman did wrong. It is to be assumed that the window of the children's room should have the same parapet height. The question to the OP is what is wrong now? Parapet height or window height. In my suggestion, any parapet height is possible.

I basically deal with the problem, not with the phrasing of the question. The draftsman has made so many mistakes here that it is probably only fixable with "do it again, but think first" and gave the OP a drawing on the basis of which one can only advise him inadequately and not effectively. For a non-skewed spatial effect, I agree with you that the parapet heights of the gable and dormer windows in the children's room should be identical (and for the gable view then also that of the bathroom). Also (as I already said) I also suspect that most likely the atypically generous window height was incorrectly specified. More from me when the OP has submitted the correct drawings.

Thank you for your effort. That is a really great suggestion, an idea we would never have come up with (because of the walk-in). It looks much tidier than our previous ones. We especially like the suggestion with the shower door facing the door because you could still use the corner under the window to organize dirty laundry or place a small cabinet, etc. Admittedly, we would have to do without both the walk-in and the double sink, but if you annoyed yourself your whole life about a lack of practicality...

We mirrored the standard floor plans and forgot to swap the window height. That means the parapet height is correct; both windows are 1.12.

We thank you all for the ideas and suggestions because now we know much more about what to pay attention to and what should be considered.

I basically deal with the problem itself, not with the question formulation.

.. which one should generally not do.

The draftsman has done so many things wrong here that it is probably only fixable by "redoing it, but thinking first"

I don't see it that way. The question here is about a bathroom that does not have optimal dimensions, but is likely part of a standard model house, which otherwise probably pleases the OP. The model house must have its reasons. If one were to focus on the issue of budget, which is likely the reason for the choice, one would have to examine salary, social status, etc. But no one is the same – and this is after all just a house-building forum – so there is no need to convert others’ lives or decisions here.

Thank you , for your effort. That is a really great suggestion, an idea we would never have come up with (because of the walk-in). It looks much tidier than our previous ones. We especially like the suggestion with the shower door towards the door because you could still use the corner under the window to organize dirty laundry or to put a small cabinet, etc. Although we would have to do without both the walk-in and the double sink, but if you were to be annoyed your whole life about missing practicality...

You should be able to get a double sink on the right wall.
