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?

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

But anyway:

Don’t you have an architect who can advise you on the bathroom layout or show you a better way?

It was just to show that a fireplace is obviously at the eaves. An architect is not involved yet; we are still in the independent planning phase.

We solved it the same way and it’s not a problem at all. What are your concerns about it?

Concerns mainly about regulations (keyword: safety) but also aesthetics: How does the chimney look as a whole if the flue behind it is wider than usual? Do you perhaps have a picture of your chimney?

Can you hear the drainage in the living room when someone uses the toilet upstairs?

In our previous house, the drain also ran through the living room, with a small shaft in a corner of the room. You don’t hear anything — it just needs to be properly insulated.

In our case, the flue behind the chimney is built into the masonry wall (24cm (9.5 inches) thick). So you don’t see or hear anything, since it is insulated. You don’t need to worry about safety; every chimney sweep will confirm that.

Our chimney is brick-built, by the way.

I assume it looks like this:

and next to this chimney shaft, there is directly the installation shaft for pipes, drainage, etc., also within the masonry? So you basically have two rectangular shafts side by side in the masonry?

Then it’s time to get one involved before a layperson sets installation spaces without professional knowledge or experience. Even a forum can’t help you with the details in such cases. Here, major, time-consuming considerations are based on a layperson’s plan that will probably not be executed as is.
