Hi, first of all, I’m new here and hope to find answers to my question.

My girlfriend and I have bought a house from 1966 and are renovating everything mostly by ourselves with the help of friends.

I asked a friend about the cost of the rough-in plumbing (from the water meter to the bathrooms, excluding fixtures and furniture), and when he told me it would be between 8,000 and 10,000 (dollars/pounds/depending on region), I was quite surprised.

Regarding the current situation: I have removed all old pipes except for the heating system and completed all core drillings. Now all the drain, cold, and hot water pipes will be replaced as surface-mounted, since my friend thinks embedding them in the exterior wall would be too risky structurally.

Light blue: bathroom on the first floor (bathtub on the left, shower top right, toilet bottom right) with a partition wall between the shower and toilet where the sink will be mounted in front.

Orange: drainage connections in the basement.

White: guest toilet on the ground floor.

Green: heating and main water connection.

Red: core drillings from the top floor down to the basement.

The entire bathroom will also have underfloor heating installed.

I hope I didn’t forget anything important, but feel free to ask if so.

Best regards, Gisi

I’ve just gone through this myself. The quotes were between 35-50 €/m (meters) of piping including full insulation (cold water 50% insulated in living areas).
Wastewater piping was around 20-30 €/m (meters) (including wall penetrations, but excluding chipping work in the existing screed/foundation slab).

Do you need a circulation pipe? Probably not in your case.

Underfloor heating renovation prices vary widely, from 20-150 €/m² (square meters) (installed serpentines on builder-supplied insulation boards up to capillary-thin-layer systems with very expensive 1.5 cm (0.6 inch) screed).

What exactly is the question?

If you are uncertain about the costs, the only way to get clarity is to request a quote from another company in your area.

That’s just how it is with existing properties. Everything is more expensive.

I don’t have any contractors working on my build; I’m doing most of it myself, except for the electrical and plumbing, which acquaintances are handling.

I just wanted a general assessment of whether the price seems reasonable, because I find it quite a bit for so little piping.
