Redesign of bathroom and bedroom. Room sizes still slightly variable.

Even with two people
140cm width is enough

That's exactly what I don't think. But if you have plan B, then everything's fine

Well, others have also told me about the size of the bed and bedroom. But they don't live with me and don't know my personal habits as well as I do.

Something like that? (just the bathtub still in "beautiful")

I am not entirely sure if it is a good idea to put the glass wall almost in the way; I would prefer it at the end of the room also because you could possibly walk along the edge here. Additionally, the shower ends right at the door or the access is there, which I would not like so much. The bathtub under the window is nice though.

If you move the bathtub further to the right into the corner, the shower should fit next to it, right?

Even for two people 140cm width is sufficient, should anything change in my situation (which I strongly hope).

no, well we have 160, that’s enough, yes. But if one of us should get a bit sicker, then there should already be 2 mattresses. One shouldn’t skimp on bed rest, because sleep is important. And the mentioned fun, you don’t always want to have that forever in the shower or at the kitchen table, but also in the bedroom. The layout of the bedroom is great, and I wouldn’t change anything about it - especially if another little pearl is going to move in there. The closet space is worth its weight in gold. The bathroom is too small. In my opinion, your little dream really needs 6 sqm to be a little dream. I would also choose a semi-open or an asymmetrical egg - with that you can probably come to terms - and it’s actually even better for bathing.
