ᐅ When a Kitchen Is to Be Converted into a Bathroom...

Aloha everyone,

we are currently remodeling our attic and have the following plan:

We would like to convert our kitchen into a bathroom.

That alone might not be such a challenge...
But we have only one water supply and only one drain—both at about 30cm (12 inches) height.

We are considering enlarging the drain from 5cm to 10cm (2 to 4 inches).
Additionally, a substructure of 12.5cm (5 inches) height to lay the supply and drain pipes underneath. Has anyone tried this before? And how does this affect the height difference to the drain? Is this physically feasible?

I took the liberty to create a small 3D model and attached it to this post. The supply and drain are marked in the red circle.

Hoping I have explained myself clearly

Upper bathroom: Bathtub on the left, sink in the middle, toilet on the right, shower.

because for the toilet you need your 10cm (5 inches) diameter for the drain.
.. that is not entirely correct ..

That makes your post useless. So, how is it correct?

... well ... for a lifting station you only need 50 mm (2 inches) ...
