Hello everyone,
we are struggling with our bathroom layout, including the plumbing plan. I hope I can explain the conditions clearly:
- Dimensions: 3.50 by 4 meters (11.5 by 13 feet)
- Below the bathroom is the guest room. Most likely, there will be a plumbing line coming down at one corner, which is acceptable. Two plumbing lines are a no-go.
- The two windows can still be moved a few centimeters.
- We are completely flexible with the two doors.
- In the bathroom, we would like: a walk-in shower, a double sink, washer and dryer (here a countertop can be used to cover a possible half-height partition wall. That means the countertop can be placed on top of the half-height partition wall)
I can’t manage to combine all components without needing a second plumbing line. Is it perhaps possible to install sanitary fixtures on the opposite wall and route the drain pipes to the other wall? Maybe we are overcomplicating things?
Here is one solution where we can route the plumbing from the sink around the corner workspace:


Does anyone have suggestions for optimization? We are not happy with the current solution.

Under the shower is not possible if you prefer a walk-in (curbless) shower.

Stein202323 May 2023 10:31@hanghaus2023 We like your suggestion from post 23 best. It will probably end up being a combined children’s and parents’ bathroom plus an additional storage room for the washing machine and dryer.
