New Location Bathroom // Wastewater Planning

Hello community!

We are currently planning to buy and renovate an old building.
We would like to redesign the layout of the rooms.

One major point that is currently causing me some concern is the wastewater planning.

The former kitchen will become a children's room.
The former bathroom will become the kitchen.
An unused room will become the bathroom and office.

Realizing the kitchen in the bathroom seems to be easier than the bathroom in a room where there are no connections.

Since all floor coverings will be renewed, I am currently considering breaking up the screed for the wastewater and thus creating a connection between the "new" bathroom and the existing wastewater pipe in the former bathroom.
The distance is about 9.5m.
With a slope of 2%, a height difference of about 19cm must be ensured.

Furthermore, I plan to use a so-called small lifting station, which is "normally" used when, for example, a bathroom is to be created in the basement. This should certainly be able to transport the wastewater from the shower, toilet, washbasin, and washing machine "directly," right?!

Do I still need a slope of 2%?
Is this project feasible without any issues?
Could my planned project possibly be implemented in another way?

Best regards

If I am not mistaken, small lifting stations are only intended for non-fecal water and do not apply to basements with toilets. For that, you need a proper lifting system.

Hello Zaba12,

I think I expressed myself a bit incorrectly.
I of course mean one with a toilet connection and "Zerkleinerungspumpe".

I can't find my desired device at the moment, but I will provide the link later.
