Bathroom renovation cost calculator: a first price for your bathroom

According to a February 2026 article by bathroom retailer X²O on the Belgian building platform Bouwinfo, a mid-range bathroom (8 to 9 m²) costs €9,000 to €15,000. A basic bathroom of the same size costs €7,000 to €10,000, a luxury one from €18,000. Those amounts cover materials and basic fitting on the pipes that are already there.

Most of the money goes to what counts per item: shower, toilet, washbasin, taps, drainage and electrics. They cost almost the same in a small bathroom as in a large one; the square metres mainly weigh on the tiling and the waterproofing. That is why a small bathroom costs more per m². For 4 to 6 m² X²O quotes €3,500 to €6,000 in basic and €5,000 to €8,000 in mid-range.

A renovation starts with demolition and ends with a waterproof, tiled room. Outside the guide prices X²O counts €500 to €1,500 to remove the old bathroom, €1,000 to €2,500 to move pipes or adapt the electrics, €1,000 to €3,000 for a ventilation system and about €1,500 for underfloor heating. The article advises a reserve of 10 to 20 per cent for what sits behind the old tiles.

Added up, a mid-range bathroom of 8 to 9 m² with demolition and new pipework comes to €10,500 to €19,000. With figures from the renovation platform Setle (February 2025), KBC puts a modest bathroom at €5,573 to €7,651 and a luxury one at €19,428 to €27,653, demolition included. Both sources are commercial: X²O sells bathrooms, KBC sells renovation loans. These are guide prices, not rates.

The calculator works with the floor area, the finish and the options you choose. It does not know your bathroom: whether the drain can stay where it is, whether there is damp in the walls, whether the floor has to come up for new pipes. Read the result as a first indication and set it next to the sector figures above. A price for your own bathroom only follows a site visit.

For the prices per size, the VAT rule and a worked example for a Ghent bathroom, read the guide on bathroom renovation cost in Belgium.

In a home older than 10 years, sanitary ware, fixed bathroom units and tiling are at 6% VAT, if the contractor supplies the materials and invoices them together with the work. Anything you buy yourself is at 21%. There is no Mijn VerbouwPremie for the bathroom itself any more: interior renovation was dropped on 1 July 2025. The grant check shows what is still possible for your work.
