Bathroom planning assistance

In my opinion, neither a modern washing machine nor a heat pump dryer produces large amounts of moisture. We also had a washing machine and dryer in a small closet in the old apartment for over three years. I never had the feeling that there was a source of special moisture there. Put it in the closet. The laundry basement is pretty much 70s.

Put it in the chamber. The laundry cellar is pretty much 70s.

Chamber or bathroom, laundry cellar definitely not (the additional note from the OP came in the green forum): the cellar is purely a machine space without clotheslines. That means the whole thing only works with "everything in the dryer," carrying wet laundry through the stairwell isn't even "70s" :-(

I would prefer that too..... but what would be the more sensible solution? To arrange the bathroom as in picture 2 in my first post or to leave it in the storage room and keep the bathroom as in picture 1? Or are there other ideas regarding bathroom layout with washing machine?

I had the washing machine in the bathroom for years and really wanted to get it out of there. I don't regret at all having it in the [Kammer] now.

And the electrician really should think about what he actually blurted out.
