Cost of a Turnkey Bathroom Renovation in Belgium

Renovating a bathroom is one of the most profitable investments to increase the value of a property in Belgium. In 2026, between the evolution of material costs and new energy standards, budgeting such a project requires rigorous precision to avoid unpleasant surprises during the works.

Average Budget by Size and Finish Quality

The cost of a complete "turnkey" renovation (including removal of the old, materials, and labor) varies mainly according to the floor area and the level of service chosen. In Belgium, the average price per m² fluctuates between 1,800 € and 3,500 € VAT incl.

Here are the price ranges observed on the Belgian market in 2026:

Bathroom Size	Economy Range	Standard Range (CULA)	Premium Range
Small (5 m²)	8,500 € – 11,000 €	12,000 € – 16,000 €	18,000 € +
Medium (8 m²)	13,000 € – 16,000 €	17,500 € – 24,000 €	28,000 € +
Large (12 m²)	18,500 € – 22,000 €	25,000 € – 35,000 €	42,000 € +

A Closer Look at the Ranges:

• Economy: Standard tiling (30x30 or 60x60), fixtures from DIY superstores, classic shower tray, simple vanity unit.
• Standard: Materials from recognized brands (such as Grohe, Hansgrohe, Villeroy & Boch), walk-in shower, large format tiling, integrated LED lighting.
• Premium: Home automation, noble materials (natural stone, Corian), concealed fixtures, freestanding bathtub, dedicated underfloor heating.

Detailed Breakdown of Expenditure Items

For a standard bathroom of 7 to 8 m², here is the typical distribution of costs. These figures include specialized labor (average hourly rate in Belgium: 55 € to 75 € excl. VAT).

1. Demolition and Disposal (800 € – 1,500 €)

This item includes the removal of old sanitary ware, chipping away wall and floor tiles, as well as the disposal of waste to an authorized sorting center. The cost of debris bags (Big Bags) and landfill fees are included.

2. Plumbing and Networks (2,500 € – 4,500 €)

This is the technical heart. It involves modifying water inlets and drains (Alpex/PVC), installing support frames for wall-hung toilets, and preparing the shower waterproofing.

• Note: Moving drainage stacks can increase this item by 30%.

3. Electricity and Ventilation (1,200 € – 2,200 €)

Compliance with RGIE (Règlement Général des Installations Électriques), installation of IP44 spotlights, secure sockets, and installation of an air extractor (local VMC) essential to prevent humidity.

4. Tiling and Preparation of Supports (3,500 € – 6,500 €)

This item includes floor leveling, installation of waterproofing mats in wet areas (mandatory in Belgium for walk-in showers), and tile laying.

• Average price including labor: 80 € to 140 € / m² depending on the tile format.

5. Supply of Sanitary Ware (3,000 € – 7,000 €)

• Walk-in shower: 1,500 € – 2,500 € (glass screen, channel drain, thermostatic mixer).
• Bathtub: 800 € – 2,000 € (acrylic or Quaryl).
• Vanity unit + mirror: 1,000 € – 2,500 €.
• Wall-hung WC: 600 € – 1,200 €.

6. Finishes and Painting (1,000 € – 1,800 €)

Plastering of non-tiled walls, anti-condensation paint, and neat silicone joints.

Global Distribution: Materials vs. Labor

In 2026, the breakdown of a bathroom renovation quote in Belgium generally follows this rule:

• Specialized labor: 50% to 55%
• Materials and supplies: 40% to 45%
• Management/Disposal fees: 5%

Labor costs are high in Belgium, but they guarantee compliance with waterproofing standards and the validity of insurance in the event of a claim (water damage).

Average Timeframe for a Turnkey Project

A complete renovation is not done in three days. Here is the realistic schedule for a general company like CULA:

1. Week 1: Protection of the site, demolition, grooving, and installation of new plumbing/electrical lines.
2. Week 2: Plastering, shower tray installation, and waterproofing.
3. Week 3: Tiling (laying and grouting).
4. Week 4: Installation of furniture, fixtures, final connections, and painting.

Average total timeframe: 12 to 18 working days.

Tips for Optimizing Your Budget

1. Keep the locations: Moving a WC or a shower drain costs between 500 € and 1,500 € more in labor.
2. The reduced VAT rate: If your home is more than 10 years old, you benefit from a VAT rate of 6% on materials AND labor, instead of 21%. This is the most significant saving.
3. Prioritize waterproofing: Save on the mirror design, but never on the waterproofing membranes under the tiles. Redoing a leaking shower costs double the original price.
4. Smart lighting: Use distinct light zones (work vs. ambiance) to transform a standard bathroom into a luxury space without major extra costs.

The 3 Critical Mistakes to Avoid

• Neglecting ventilation: Without efficient mechanical extraction, your joints will turn black within 24 months and the paint will peel, ruining your investment.
• Wanting to buy your own materials: Most contractors do not offer a ten-year warranty on products they did not provide, and you will pay 21% VAT in store instead of 6% via the pro.
• Underestimating electricity: Bathrooms are divided into "safety volumes." Failure to respect the minimum distances between a water point and a socket will make your installation non-compliant upon resale.

FAQ – Frequently Asked Questions

What is the price for replacing just a bathtub with a walk-in shower? In Belgium, this transformation generally costs between 4,500 € and 7,000 € VAT incl., including removal, plumbing adaptation, wall waterproofing, and installation of the new tray.

Is it possible to renovate a bathroom for less than 10,000 €? Yes, for a small area (less than 5 m²) by keeping current water inlets and choosing entry-level materials, but this often does not include a total overhaul of the concealed networks.

Can I benefit from renovation grants in Belgium for my bathroom? There is no specific "bathroom grant" for aesthetics. However, some regions grant aid for adaptation for people with reduced mobility (PRM) or for the installation of a thermodynamic water heater.

Why have prices increased since 2023? The increase is due to rising energy costs (impacting tile and ceramic production), the wage indexation of the construction sector, and new environmental certification requirements.

Conclusion

Bathroom renovation in Belgium is a technical project that requires perfect coordination between the plumber, the electrician, and the tiler. While the average cost of 15,000 € to 20,000 € may seem high, it guarantees the structural longevity of your home and unparalleled daily comfort.
