Thank you!
Because of the slants, the bathtub has to be placed by the window in our place.
At the moment, I lean towards my design with the changed door hinge, but it all turns out to be noticeably tighter than hoped. Next to the bathroom is the study, which is only 10m2 in size, and I would reluctantly have to take something away from it.
I find the masonry solution nicer, as the glass walls require significantly more maintenance. The glass cabins we saw in young houses already didn’t look so great after a short time. That’s where the tip for a walk-in shower came from.
