Double switch at the door.
Oh, you’re just jealous!
At least I prefer to be able to turn the mirror light on and off while standing in front of the mirror.
In the bathroom so far, I always have to go to the door. Even if it’s just two steps, it’s annoying.
We also have a T-solution in the bathroom and don't regret it! We still like it!
I find the bathtub in front of the window unfortunate. If we did it that way, we would only have about 60 cm between the tub and the wall toilet. So that's not feasible either.
