Hello,
I did not respond to the question about the window because I thought you were asking about the window with the error message.
The window is 1.26m and has a raw floor to sill height of 1.0m. Floor construction 10cm.
The shell is in place, exactly. However, the walls of the WC will be constructed as drywall. That means the wall opposite the stairs could still move to the right, but this would be at the expense of the children's room.
Attached is a painted sketch.
And now that I think about it, a 1.8m bathtub definitely won't fit on the 1.4m wall..
