Bathroom renovation cost in Belgium 2026: by size, finish level and line item

Short answer: In 2026, Belgian price guides put a bathroom renovation at roughly €5,000–€8,000 (basic) to €12,000–€18,000 (high-end) for 4 to 6 m², and €8,000–€30,000 for 6 to 10 m². Per m², sources range from €750 to €3,500 or more. The biggest cost jump is moving drains: €800–€2,500 or more extra, because the floor and screed must be opened up.

What does a bathroom renovation cost by size and finish level?

In Belgium, expect roughly €5,000–€18,000 for a 4 to 6 m² bathroom and €8,000–€30,000 for 6 to 10 m², depending on basic, mid-range or high-end finish. The table below uses the ranges from one Belgian price guide; they are market ranges, not a price list from the company.

Other guides show lower totals because they count fewer items. Bouwinfo (X²O Badkamers, February 2026) gives €3,500–€6,000 (basic), €5,000–€8,000 (mid) and from €10,000 (high-end) for 4–6 m², including VAT but excluding demolition and plumbing changes. Always check what a price actually covers.

Per m² the sources differ widely: RenoZen quotes €750–€1,500 for standard and €1,500–€2,500+ for high-end, Homedeal €1,200–€1,500 (budget), €1,500–€2,200 (average) and €2,200–€3,500+ (luxury), and Bouwplannen.be €800–€1,800. A per-m² figure is only a rough guide: small bathrooms cost more per m² because plumbing and electrics cost about the same in 4 m² as in 8 m². See also our bathroom renovation page.

What do demolition, plumbing, electrics, waterproofing and repairs cost besides furniture and tiles?

Beyond furniture and tiles, the technical side takes a large share: demolition, plumbing, electrics and ventilation often add up to more than the visible sanitaryware. Guide prices from Belgian sources:

In practice waterproofing sits inside the floor and wall finishing package and rarely gets its own line. The same goes for making good walls and floors after demolition: none of the sources we checked gives a separate price. Ask for it to be listed explicitly in the quote.

Why is moving drains the biggest cost jump?

Moving a drain costs €800–€2,500 and sometimes more for water and drainage according to Homedeal, and Bouwinfo quotes €1,000–€2,500 for moving pipes and adapting electrics. It is expensive because it is far more than shifting one pipe.

• Floor and screed opened up. A drain needs a slope and usually runs in or under the screed. It has to be broken out, re-laid and left to dry (according to Immomakelaarvergelijker, moving pipes is the biggest cost item).
• More hours, several trades. Plumber, tiler and often an electrician work one after another.
• Knock-on work. New tiles over the repaired floor, extra waterproofing and sometimes changes to electrics or underfloor heating.

In Bouwplannen.be's example of an average standard bathroom (total ± €12,000–€14,000), about €3,000 is for new pipework (water and drainage) and electrics; for a premium bathroom of 10 m² or more, it is ± €5,000–€8,000 for fully new pipework, underfloor heating and electrics. Keeping the same layout can, per the same source, save hundreds to thousands of euros. Before moving anything, have a professional assess where the stack is and how far the new position is from it.

What else drives the price?

Besides the layout, the choice of sanitaryware, ventilation and unforeseen findings decide the final amount.

• Sanitaryware and furniture: a bath costs €1,000–€4,000+ installed; a luxury walk-in shower costs €4,000–€8,000+ according to Homedeal.
• Underfloor heating: Bouwinfo cites about €1,500 extra.
• Size: plumbing, electrics and ventilation cost about the same in 4 m² as in 8 m².
• Unforeseen work: Bouwinfo recommends 10 to 20% extra budget for surprises in older homes.

How do you compare quotes and avoid surprises?

Ask for three quotes based on the same description, itemised line by line. It is the only way to see whether a lower price is really cheaper or just covers less.

1. Have demolition, skip and rubble removal listed separately.
2. Have plumbing, drainage and electrics itemised, stating whether the layout changes.
3. Check that waterproofing, making good of walls and floor, and ventilation are included.
4. See whether sanitaryware and tiles are a provisional sum or a named brand and reference.
5. Ask whether the price includes VAT and whether it is 6% or 21%.
6. Agree a reserve for unforeseen work.

A fixed written quote after a site visit gives the most certainty. Start with a rough budget in our renovation calculator or read about our renovation work. Alpha Services Benelux carries out bathroom renovations with its own team, by appointment.

VAT 6% or 21% and subsidies

According to Belgian price guides, the reduced 6% VAT rate applies to a dwelling at least 10 years old (since first occupation), used mainly as a private home, when the contractor invoices the end consumer directly. Materials you buy yourself stay at 21%. Check the exact conditions with the Federal Public Service Finance before signing.

For subsidies we point to the official portals, because amounts and conditions change: vlaanderen.be/mijn-verbouwpremie in Flanders, Homegrade and your municipality in Brussels, and energie.wallonie.be in Wallonia. We deliberately state no amounts here.
