Attack direction and door position in the bathroom upstairs

our current door opens towards the shower and I think to myself every time, which idiot came up with that. the door handle of the room door hits the glass door of the shower every time you open the door too far. opening towards the sink might not be great either if something is supposed to stand between the door and the sink (e.g. a cabinet or something, with 50cm depth you can do a lot ?!) opening outwards would really be the better alternative, do you have the rest of the floor plan of the floor?!

Now they are deciding only because of the 40 cm or 50 cm wall distance, as they are starting to build the upper floor masonry.
Remaining floor plan:



Outside is difficult, as the corridor runs there. Objects in the bathroom will have a pre-wall on both sides (however, probably only 3 cm on the shower and bathtub side according to the plumbing specialist). The pre-wall on the washbasin side will only extend up to the washbasin, so that a bathroom cabinet (approx. 30 cm) can be attached next to it.

I would not open the door outwards for purely aesthetic reasons. All other doors also open inwards.
