Installing a wastewater pipe costs an average of €15 per meter.
Laying a water or wastewater line typically costs between €7 and €97 per meter.
As part of a bathroom renovation, it often makes sense to replace both the drinking water and wastewater pipes as well.
The following factors can affect the total cost:
-
Length of the piping network
-
Material prices
-
Labor costs
-
Possible additional expenses
What Are the Travel Costs?
If the construction site is outside the craftsman’s service area, many contractors charge a travel fee, which can range between €10 and €50, depending on the region.
How Much Do Wastewater Pipes Cost?
For indoor drainage systems, HT pipes (high-temperature pipes) or PE pipes are commonly used. These are available in various sizes and configurations.
Below are the estimated material and labor costs combined:
| Material | Price (incl. labor) |
|---|---|
| HT pipe, DN50 | €12–18/m |
| HT pipe, DN70 | €19–27/m |
| HT pipe, DN100 | €19–34/m |
| HT bend, DN50 | €4–13 each |
| HT bend, DN70 | €4–17 each |
| HT bend, DN100 | €5–15 each |
| HT branch, DN50 | €5–19 each |
| HT branch, DN70 | €4–14 each |
| HT branch, DN100 | €5–90 each |
| PE pipe, DN70 | €8–34/m |
| PE pipe, DN100 | €36–115/m |
| PE pipe, DN150 | €64–89/m |
| PE bend, DN70 | €5–12 each |
| PE bend, DN100 | €17–28 each |
| PE branch, DN70 | €10–13 each |
| PE branch, DN100 | €18–29 each |
| PE branch, DN150 | €78–121 each |
How Much Do Drinking Water Pipes Cost?
For drinking water, multi-layer composite pipes (metal composite pipes) are often used. Depending on the pipe diameter, prices including labor range from €2 to €54 per meter.
If you choose stainless steel pipes, costs are slightly higher — between €8 and €75 per meter, depending on the diameter.
What Additional Costs Should I Expect?
Additional expenses include small parts such as pipe connectors, non-return valves, and various fittings. Experts estimate about €3 to €5 per meter, including labor.
Example Calculation: Installing a Wastewater Pipe
As part of a bathroom renovation, the toilet will be moved to a new position. Pipes with DN100 and one bend are required. The following table shows an example of the total cost:
| Item | Cost |
|---|---|
| Laying HT pipe | €25 |
| Installing HT bend | €10 |
| Additional materials | €4 |
| Travel costs | €10 |
| Total | €49 |
