ᐅ Installation shaft and chimney flue combined in one?

Hello everyone,

We are planning to include a second bathroom on the upper floor, but underneath on the ground floor there is actually no bathroom or kitchen, meaning the plumbing shaft is essentially located in the middle of the living/dining area. However, we are planning to install a fireplace exactly there. Now the question is: Could we place the plumbing shaft directly next to the chimney flue? If this projection is somewhat wider, it shouldn’t affect the appearance much, since a kind of panoramic fireplace is planned in front of it anyway. I hope I have made my idea clear.

If that’s not possible, could the plumbing shaft perhaps be moved so that it doesn’t run through the living room but instead through the guest room? What is the maximum flexibility here, or does the shaft have to run directly down from the bathroom?

Thank you very much for your support, and I apologize for not searching precisely for the chimney location in the forum 😉

And the bathroom is directly above the living room? Or the dining area?
How is the drainage supposed to work there?
...
Oh, that’s why the service duct is there 😉

Perhaps there is a chimney specialist in the forum who can say whether an installation shaft directly next to the chimney flue is feasible 😀

By the way, regarding the chimney at the eaves:

  • For a roof pitch over 20%: the chimney outlet must be at least 40 cm (16 inches) above the ridge or at least 230 cm (7.5 feet) away from the roof surface in horizontal distance. The same distance applies to external chimneys on the building’s exterior wall.
It should be possible according to regulations, as far as I understand. By the way, it is planned to be a hipped roof.

😎... A townhouse is something different from an architect-designed gable roof house.

But anyway:

Don’t you have an architect who can advise you on the layout of the bathrooms or show you how to improve it?

If that’s not possible, could the installation shaft be moved so it doesn’t run through the living room but instead through the guest room? What is the maximum allowed here, or does the shaft have to be routed directly from the bathroom downwards?

We solved it exactly like that and it’s absolutely no problem. What concerns do you have about it?
