Thanks to you all in advance! Variant 5 seems to be in the lead.
I like variant 5 best. The only disadvantage is that you have to pass the shower first.
That's true. It's hard to judge whether the passage is too narrow. However, with the position of the shower + toilet, we hardly have any room left to shift towards the sloping roof, since I am almost 2 meters tall and still need to be able to stand at/in front of the toilet.
But with variant 5 there’s again the problem that everyone has to pass the washbasin.
Do you think so? Once you pass the shower, you can go left without running into the back of the person at the washbasin.
...and we have a "normal" bathtub that we have placed at a slight angle.
But such a "normal" tub placed in the corner takes up a lot more floor space. Do you have a bigger bathroom?
