Price comparison per m² (at 9 m²)

Conclusion

For an average bathroom of 9 m², the costs range from € 6,500 to € 25,000+, depending on the comfort level, material choice, installation requirements, and customization. The price per m² decreases for larger areas but increases with luxury finishes or layout changes. Thorough preparation and a detailed quote are essential for a realistic budget estimate.

• Smaller bathrooms have relatively higher costs per m² due to fixed basic work (such as drainage, electricity, connection points).
• Larger bathrooms benefit from economies of scale, but the absolute costs are higher due to more labor time.
• The prices are based on professional execution by recognized installers, tilers and plumbers.

Based on an average bathroom of 6 to 9 m² – incl. VAT and assembly

Explanation by category

1. Sanitary ware and furniture (25–35%)

• Toilet (surface-mounted or built-in)
• Vanity unit, mirrors
• Shower or bath
• Taps and accessories

The choice of brand, design, and installation has a major impact on this component.

2. Tiles and wall finishes (20–25%)

• Wall and floor tiles or alternatives such as Beton Ciré
• Tile adhesive, grout, sealant
• Tiling (labour)

Luxurious finishes increase both material costs and labour intensity.

3. Pipework and technical installations (15–20%)

• Water pipes, drains, electricity
• Relocating or renewing connection points
• Mechanical ventilation or air exchange

Changing the layout or adding extra connection points will significantly increase this portion.

4. Labor and Assembly (20–30%)

• Demolition of old bathroom
• Installation of sanitary ware, finishing
• Project coordination and handover

Labor costs are highly dependent on planning, accessibility, and required disciplines.

5. Unforeseen / Additional Work (5–10%)

• Leveling floor or walls
• Unexpected pipe problems or outdated installations
• Adjustments during execution

It is recommended to reserve at least 10% of the budget for this category.

Example: Distribution for a bathroom renovation of € 12,000

Conclusion

The cost structure of a bathroom renovation is evenly divided between material, labor, and technology. The final costs depend heavily on design choices, whether or not the layout is changed, and the desired finish. By making clear agreements in advance and including a provision for additional work, you can avoid surprises during execution.

1. Bathroom Surface Area

• Smaller bathrooms (≤ 5 m²): relatively higher costs per m² due to fixed basic costs for plumbing, sanitary ware and labor.
• Larger bathrooms (≥ 10 m²): lower price per m², but higher absolute total price due to extra tiles, installation work and labor.

2. Current state and technical background

• Poor pipework, old drains or moisture damage cause extra repair and preparation costs.
• Uneven floors or walls require leveling or extra mounting facilities.

3. Relocating connections

• Any change in the position of the toilet, shower or sink means extra piping and demolition.
• Average additional costs: € 1,000 – € 3,000, depending on accessibility and surface (e.g. concrete floor vs. crawl space).

4. Choice of sanitary ware and finishing

5. Type of wall and floor finish

Luxury or non-standard finishes involve higher assembly hours and material costs.

6. Number of functions and facilities

• Extra facilities such as a freestanding bath, double sink, bidet or underfloor heating increase the installation complexity.
• More connection points mean more working hours, extra groups in the meter cupboard, and longer lead time.

7. Underfloor heating or supplementary heating

8. Labor and craftsmanship

• The costs depend heavily on the number of disciplines: plumber, tiler, electrician and plasterer.
• Average labor costs: € 45 – € 80 per hour, depending on region and specialization.
• Emergency jobs or weekend work may incur surcharges.

9. Accessibility and logistics

• Apartment on a floor without an elevator or with narrow passages increases the carrying and assembly time.
• Poor accessibility of pipes or the absence of a shaft causes hacking and demolition work.

10. Project approach: total package vs. own management

Conclusion

The price of a bathroom renovation depends on technical, aesthetic, and practical choices. Layout changes, luxury sanitary ware, high-quality finishes, and extra amenities such as underfloor heating or home automation are the biggest cost-increasing factors. A realistic budget starts with understanding these elements and requesting a specified quote.

• Specifications of materials
• Labor hours and hourly rates
• Additional work provisions

1. What does an average full bathroom renovation cost?

The costs typically range between € 6,500 and € 25,000, depending on the area, finishes, material choice, and installation complexity. Most renovations of 6 to 9 m² fall within the range of € 9,500 to € 14,000.

2. How long does a bathroom renovation take?

The average renovation duration is 10 to 15 working days, excluding preparation time. Luxury projects or renovations with custom work and complex installations can take up to 4 weeks.

3. Can I continue to use the bathroom during the renovation?

No. During the work, the bathroom is usually completely out of order. If the only bathroom in the house is being renovated, a temporary alternative sanitary facility is necessary.

4. Do I need a permit for a bathroom renovation?

In almost all cases, no building permit is required, unless:

• There is a change to load-bearing structures
• Work is being done on a monument or protected townscape

5. Can I save money by doing work myself?

Yes, especially by:

• Demolishing and disposing of rubble yourself
• Painting or mounting accessories yourself
  Note: installation work, tiling, and waterproofing require professional knowledge.

6. What determines the final price the most?

The biggest price determinants are:

• Layout changes (relocating pipes)
• Type of sanitary ware and built-in solutions
• Floor and wall finishes
• Additional features such as underfloor heating or home automation

7. What is the lifespan of a new bathroom?

A well-executed bathroom lasts an average of 15 to 25 years. The lifespan depends on the chosen material, maintenance, and intensity of use.

8. What is the difference between built-in and surface-mounted faucets?

• Built-in faucets are integrated into the wall, aesthetically sleeker but more expensive to install.
• Surface-mounted faucets are easier to install and cheaper, but are more noticeable.

9. Do I get a guarantee on a bathroom renovation?

Yes.

• Installation guarantee: usually 2 to 5 years (depending on the contractor)
• Manufacturer's guarantee: 2 to 10 years on sanitary products and equipment

Always ask for written confirmation of the guarantee conditions.

10. Is there a subsidy available for bathroom renovation?

In principle, no. Exceptions are:

• Wmo subsidy via municipality for medical necessity (e.g. care bathroom)
• ISDE subsidy for energy-related interventions such as heat pump or insulation (not for standard bathrooms)

11. When is the best time to carry out a renovation?

Preferably outside the busy spring.
Advantageous periods:

• Late summer or autumn
• Winter (outside the Christmas period)
  During these periods, installers are more often available and prices are more stable.

12. What are common mistakes during bathroom renovations?

• Not considering sufficient ventilation
• Unclear agreements about additional work
• No provision for unforeseen costs
• Performing the installation yourself without technical knowledge
• Errors in slope or waterproofing for walk-in showers

Conclusion

A bathroom renovation requires good preparation and realistic expectations. By understanding common questions and pitfalls, you can manage costs, time, and risks. Requesting multiple detailed quotes is an important first step towards successful execution.
