Floor plan of master bathroom and passage to bedroom

I would leave the sink by the window, just like in the first plan (daylight) The niche is also nice for that, I think, toilet and door where they are now, but hinged the other way. Shower and bathtub lined up in a row at the top of the plan.

...in front of the toilet comes the frame, you have to measure if it's too tight, possibly move the door? The bathroom door made of frosted glass is also very nice because of the light. Possibly make it 1m if possible, that can be important for later. The view when entering the bathroom and also a (stylish) washbasin, I would prefer, and in the bath directly in front of the window is of course great.
