Costs for the heating & sanitary trade

Old Swede...

You have control over sanitary objects yourself. Hard to say much about it, but of course you let go of such an amount quickly and haven’t even reached the top shelf. But you can also get it cheaper.
Where my jaw really drops is the rest.
Stgt. is of course top price category but for comparison.
We built last year, 140 sqm living space. + basement 70 sqm with underfloor heating. Air-to-water heat pump with indoor installation. One large bathroom upstairs, one small guest bathroom/WC downstairs. Sanitary and heating together 55k. Add another 10k because we had furniture/mirror cabinet and glass cabins ourselves or separately. Sure, you have a children’s bathroom and WC separately. But that doesn’t justify the difference.
We are 50 km from Stgt.

Your prices are really fierce!

Edit: My prices are gross!

That’s true.
140k€ for sanitary and heating. phew...
We are between Stuttgart and Munich and paid 30k€ for the entire sanitary and heating work (approx. 225 sqm underfloor heating, gas+solar, sanitary objects from the internet) from a local company. 2019 prices.

: So I suspect a defensive offer. He seems to be doing so well that he only wants to carry out the order "at a premium." I must be glad that those I contacted simply declined. I almost think it's not worth going through individual items with him anymore. To the files and move on.

By the way, I'm going with this one now: I hope that the execution goes just as well as the preliminary discussions. I received the two outstanding offers yesterday, but one was simply too incomplete and the other about 10% more expensive with a poorer selection of sanitary fixtures.

one quick question: how is the controlled residential ventilation installed at your place? In the concrete ceiling? Is that position 3.6 in the offer?

Thanks!

No, the original plan was to install the ductwork for the ground floor in the floor structure of the upper floors, as well as the installation for the upper floor in the suspended ceiling of the attic. Now, for aesthetic reasons, we are considering switching to floor outlets for the supply air on the ground floor. But it’s still a bit problematic regarding the installation in the floor structure of the ground floor. There is thermal insulation planned on the floor slab here (I don’t have any under the floor slab) and the ventilation pipes should also be insulated, otherwise you get cooled supply air. The Valloflex basic package includes the piping and two air distributors plus accessories. But it comes with round pipes; I will probably have to switch to oval pipes. It is also possible to install it in the concrete ceiling, but then it has to be cast thicker = additional costs. I think my general contractor wanted 4000 EUR for that; so I preferred to take the ceiling height increase for half the price and integrated it into the floor structure.

Ok, thanks for the quick response. We will have to weigh it again. My preference would be in the ceiling, and with individual awarding, those few extra centimeters of concrete hopefully won’t be that expensive.

How much additional floor buildup is needed otherwise approximately? We have planned a few extra centimeters of ceiling on purpose, but I would like to keep as much of it as possible...
