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?

The chimney outlet must be at least 40 cm (16 inches) above the roof ridge or at least 230 cm (7.5 feet) horizontally away from the roof surface.

If you don’t understand the implication in your text, just look at your pictures ;-)

Maybe there is a chimney installer in the forum who can say if an installation shaft can be placed directly next to the chimney flue.

Exhaust gases won’t prevent you from also having cold water supply in the bathroom. And you can safely run Ethernet cables in the installation shaft as well—whether copper or fiber optic.

After reading for two or three weekends, your questions and ideas should be noticeably less naive—this is why I recommended this approach, which has helped thousands of others.

Then it’s about time before a layperson sets installation spaces without professional knowledge or experience.
Even a forum won’t help with the details in that case.
Here, major time-consuming considerations are based on an amateur plan that probably won’t be executed as is.


If you read my first post, the detailed question arose because we are considering planning the bathroom above the living room to avoid giving up the home office room and to have the children’s bedrooms located on the west side at the same time. Therefore, it is perfectly reasonable to inquire at this stage whether a service shaft can be placed in that spot 😉 If that is not possible, we will start thinking about an alternative plan in time. But if it is feasible and we get positive feedback here, why not use the forum?

Trying to understand this (alleged?) causality based solely on a first-floor layout sketch is pushing the limits of what can reasonably be expected from community advice. If even Yvonne and I, who are certainly experienced members here, struggle to make sense of your puzzle pieces in the question, that should give you pause—though apparently it does not. Joining the design process so close to the final result is already problematic, and extending that approach to the design discussion is even more so. When several members still try to remain patient under these circumstances, that is more luck than merit. ;-)

I understand what you’re saying. It’s very frustrating when people open threads here without doing any research at all.

But constantly talking down to people and dismissing questions from non-experts as naïve isn’t helpful—in fact, it comes across as rude. It’s better not to reply at all than to make people feel foolish or create a negative atmosphere. Take a look from the very first moment at the tone you used throughout this thread—I hope (assuming you can self-reflect to some degree) that you can understand my point here. I have done my research and can show you a thread that already addressed my question. Simply saying that the design should be thrown in the trash is easy 😉 The entire planning process is just that—a process—and basic questions along the way to the final floor plan, such as whether the bathroom extends over living space or a chimney shaft, belong to it.

I think the solution is the trash bin and rolling the dice again.

What’s wrong with the tone? This is experienced advice, nothing more. I can see very quickly from a floor plan when it’s a dead end. Only a cynic would have encouraged you here to "refine" this plan. A trash bin is a friend and a helper in grieving when a plan is a dead end, and crumpling it up clears the way. No one is counting how OFTEN you roll the dice—but we celebrate with anyone who then rolls three sixes in a row. Just having the shaft is wasted palliative care. You are still missing your chance for a push in the right direction by only partially and verbally describing the ground floor. Most likely, we would have long ago found where you could untangle the knot. Because in the OTHER floor you cannot fix a wrong turn. If you prefer to complain, that’s not MY fault.

The installation shaft next to the fireplace is not an issue—we did it the same way. On the other side of the fireplace, there is also a warm air shaft leading to the upper floor, so the convection heat from the stove doesn’t all enter the living area. The installation shaft runs from the basement up to the attic, with access on every floor, and houses various services such as photovoltaic electricity, speaker cables, heating control, etc. The larger shaft only runs from the basement to the ceiling of the ground floor and mainly contains the mechanical ventilation system for the ground and upper floors.

Apart from my personal preference for more rectangular floor plans with a pitched roof and plenty of photovoltaic panels, I believe your layout has a lot of room for improvement. The solution with two small bathrooms is actually quite poor. Make one proper bathroom and place it above the kitchen or near the chimney shaft. Whether children’s rooms need to be 19 m² (204 sq ft) is also debatable. Ours are around 15.5 m² (167 sq ft), and instead we placed a central family room.
The suboptimal placement of the fireplace at the eaves has already been mentioned. Visually, that is not very appealing.
