8.02m positioning sink / toilet

Hello, I am grateful for any tip or opinion
There are two of us and eventually three
But we can't change anything about the position of the door now.
Ypg I look forward to your suggestion

Are the 2 meters the shell construction measurement?
How wide is the door?
And where is the drain?
Has this variant been confirmed to you?

Regards

Good morning The 2 meters are the rough construction dimension, but we have already measured and it fits. The door is 88 cm wide.

The drain pipe is located all the way to the right next to the window. For the shower, however, we use the drain pipe from the hallway (opposite the room) because otherwise we did not get enough slope. This variant has already been approved by us. Now it is only about the placement of the sink and the toilet

As I already wrote, the passage between the shower corner and the washbasin (or toilet), which hang in front of a pre-wall, becomes a bottleneck. I have already seen 2.20 wide bathrooms several times, but already plastered and tiled... With you, you can only reasonably expect about 1.95 in width. 17cm tiled pre-wall, 48 washbasin, 90 the shower... that makes a total of 1.55... leaving 40 cm for the passage. This has nothing to do with whether the door is on the left or right. In your perspectives, the narrowness cannot be seen. You should at least have the door open outwards... Regards

Thank you
Based on your advice, we now have this option, what do you think?
There was a 65 cm distance between the washbasin and the toilet

I find it clearly better
