Bathroom 18 m² - Ideas and Planning

What I consider to be the absolute worst case: you can practically no longer reach the only window in the bathroom, but have to climb over the tub every time. This is totally annoying, since you probably want to open this window most frequently in the whole house.

In my opinion, this bathroom would really be a case for a T-solution. However: do we need this mega cabinet? What about the connections? Are they still flexible? What about additional windows?

To free the window, I would probably plan built-in appliances together with the washbasins as base cabinets and the T. Actually, there should also be a window by the shower, which I have not sketched now, since apparently this is no longer possible.

I think the idea of the large cabinet is good at first because you can place the devices higher in it. I no longer like having the washing machine and dryer at under-counter height.

However, I also find the tub in front of the window really inconvenient.

Connections are basically still flexible. A window can also still be installed. By floor plan I only meant the walls. I wasn't very precise there.

In addition, we were told that the toilet upstairs has to be exactly in the same position as the one in the downstairs guest bathroom (which can no longer be adjusted at all...) because of the sewage pipe. If that weren't the case, we would be very flexible. From our point of view, the toilet wouldn't have to be directly on top of each other. Or did I misunderstand it regarding the toilets being one above the other?

Or did I misunderstand the overlapping toilets?

Yes. If they share a common drain pipe, they should be close to each other. Overlapping means in the same corner of the house and roughly in the same position.

Sewer pipe.

Above that, a stack vent running over the roof will be added. It requires a (drywall) enclosure of about 10 x 10 cm upwards, which will probably be detailed later in the execution planning.

And yes, the tub away from the window...

Oh, so only the walls are fixed and the wastewater pipe for the toilet more or less. I would probably still go with the T because of the size. The windows are usually not as flexible as you think. The exterior view is supposed to look right as well. It seems there are no slanted walls? Otherwise, the exact measurements would be needed first to get an idea.
