Price for laundry chute

Hello everyone,

the interior fitting is just starting with us. Now we have to take care of the pipe for the laundry chute, as this is not included in the house offer. We have now received an offer from our plumbing company. The price almost blew us away, 1800 euros. Is that normal? Did you also pay that much? Everything including material and installation is included. But still a lot of money.
The pipe should be 5 meters long with a diameter of 30 cm.

Or are there alternatives to the KG pipe?

I paid EUR 60.00 for 5 meters of KG pipe with a diameter of 300 mm. The craftsmen cut the hole in the ceiling for me; I installed it myself. However, only from the ground floor to the upper floor, so logically I shortened the pipe beforehand...

Nice cladding, flap(s), etc. will come extra.

Only the pipe surely cannot cost EUR 1800, how large is the installation effort? You can’t just install a 5-meter-long pipe vertically at a normal room height...

I ordered spiral duct DN 280, 2m including 2 clamps and shipping 60€. Breakthrough planned during shell construction, it was immediately recessed into the concrete ceiling. Below in the utility room it will be clad and a basket will be placed underneath. Above in the bathroom there will be a cabinet hanging directly above it without a bottom with a laundry flap.

Depends on the effort. Just the pipe through the ceiling can't cost the world. If the top and bottom are also covered, and maybe there's a nice cover with a flap on top, then it's more likely. Maybe just have the pipe installed and do the rest yourself. If it costs more than 200€, I would ask them to explain exactly what they're doing.

The flap is the most expensive if you order it specifically for such a shaft - all the providers are just not reasonable when they want to charge 300-400 for a piece of sheet metal.

I happened to find a provider who offers the flaps made of drywall with magnets and seals ready-made. Also about a hundred, but it was worth it to me.

KG pipe as a 315 would already have been in the triple digits - especially since it also has weight. It goes from the basement to the upper floor.

I also bought spiral seam pipe (also around 50 euros including shipping) and then installed it with appropriate clamps and expanding foam.

Then another box behind the flap so that you don’t see the bare masonry.

Everything can be done well in EL – only breakthroughs should be planned during the shell construction.

For my construction, they also wanted 700€ gross for the kg of pipe from the utility room to the attic (basically preparation for solar system later). The hole in the ceiling was already there, the cladding of the other pipes had to happen anyway. We didn’t do it for the money because no one wanted to negotiate the price with us (unfortunately a bit unfortunate).
