I am currently building a single-story house without a basement through a developer. The drainage pipes are causing me some concerns. In the bathroom, the drain pipe is located on the outer edge, not directly under the shower or bathtub. The same issue exists in the kitchen, where there is no drain pipe, and the wastewater is supposed to be routed to the guest toilet (there are two walls in between). After discussing this with the developer, I was told this is normal. However, a good friend of mine said that drain pipes are usually installed before pouring the concrete slab, right where the drains will be.
I am a bit unsure if everything is correct. I would appreciate any feedback.
Best regards

What does the drainage plan look like? It should be clearly outlined there.
In our case, the drain pipes run beneath the slab; all drains were installed there before pouring the concrete. The main sewer pipe, to which the other pipes are connected, has been routed to the exterior wall.
Best regards,
Michael

that was a quick reply, thanks! In my case, each bathroom has a single drain pipe. These pipes are also located in the exterior wall and run through the floor slab. The question is whether it is normal to have wastewater from the shower, bathtub, sink, and toilet all connected to this one pipe in the bathroom, or if multiple drain pipes should have been installed. For example, the kitchen does not have its own drain pipe, and the pipe runs all the way to the guest bathroom.

ah sorry, then I misunderstood. We have a drain at every point in each room where later a device will be installed that requires a wastewater connection. For example, in the guest toilet there are two: one for the toilet and one for the washbasin. In the kitchen, one for the sink and another where the wastewater from the bathroom above will drain down.
Unfortunately, I can’t answer what is currently considered best practice (one of my favorite terms since we started building), how much wastewater can or should be combined in one pipe, etc. I can imagine that the kitchen and guest toilet pipes could get quite tight in diameter, especially if the dishwasher is draining, someone is washing dishes by hand in the kitchen, and at the same time someone is using the guest toilet and washing their hands. But I have no idea how to calculate that...

Michael

hm... I have just built recently: the county authority also reviews and ultimately approves the drainage plan as part of the building permit / planning permission. I wouldn’t worry about it. I don’t have our plan in mind anymore, but on the upper floor, the pipes from the washbasin, shower, and toilet are also combined and routed in one stack... It should all be correct... but caution: this is just a layperson’s opinion.
Well, it could become problematic if the connections are too far apart. In other words: you need to run the line from the kitchen to the toilet. Your floor slab is already finished – which means you only have the screed/insulation for the slope. There must be a slope from the kitchen to the drain to prevent water from standing in the pipe.
