Sewer planning: Toilet under the shower along the side?

Good morning,

we received the floor slab plans including the wastewater plans today.

Now I am wondering if it is okay that the wastewater from the toilet runs under the drain of the shower.


Sketch of pipe routing:
Main wastewater pipe <-- shower (bathroom 1) <-- toilet (bathroom 2) <-- shower (bathroom 2)

The description is indeed a bit vague. Can't you upload the plan? Based on the description alone, there's nothing against it, as long as the slope is correct.

I have informed myself elsewhere, [Geruchsverschlüsse] will be installed, so my question has been answered.
