so I think the bathroom as I have planned it now is spacious enough, the shower niche is nice and large, a great washbasin fits in and also a nice bathtub...
it doesn’t always have to be the popular T shape (personally, I don’t really like that anyway)
But then I would be very disappointed with the architect, because she suggested it that way.
I don’t mean the architect’s plan, but the plan you posted, maybe the staircase is just shifted there for you, but in the architect’s plan it’s definitely further away from the wall (in mine exactly the same), I estimate about 1.30 m, with you maybe only about 60 cm
