Bathroom renovation in Luxembourg

Our services

Our teams work on all technical and aesthetic aspects of a bathroom, with plumbing, electricity, and tiling coordinated by the same plumber and the same contact person.

• Removal and disposal of the old installation
• Complete overhaul of plumbing and electricity
• Installation of walk-in shower or bathtub
• Floor and wall tiling, with waterproofing treatment
• Fit-out of storage and custom furniture
• Accessibility adaptation: low shower tray, grab bars, raised toilet

Process of a bathroom renovation

The technical visit begins with an accurate measurement of the room and a check of the condition of the existing waterproofing. These two elements directly determine what is feasible and the detailed estimate that follows.

After the removal of the old installation, the plumbing and electrical networks are addressed first. The waterproofing is then redone before the tiling is installed, a step that allows no shortcuts to avoid future water damage.

The finishes (tiles, faucets, furniture, lighting) are done last, once the waterproofing tests are validated. A complete bathroom renovation usually takes between one and three weeks depending on the scope of work.

Areas of intervention in Luxembourg City

• Cents: housing from the 1980s-1990s to modernize
• Belair and Merl: villas with bathrooms to rethink
• Bonnevoie: small bathrooms to optimize in size
• Kirchberg and Gasperich: high-end renovations in recent existing properties

Regulations and Assistance in Luxembourg

Old bathrooms in Cents and neighboring areas sometimes have electrical installations that do not comply with current standards, particularly around the shower or bathtub. A complete upgrade to standards is systematically included in our interventions, even when the client has not explicitly requested it initially.

The waterproofing and ventilation of a bathroom are governed by specific standards, especially around water points and electrical outlets. These rules are non-negotiable and determine the long-term safety of the installation.

For a dwelling over ten years old designated as the main residence, a super-reduced VAT rate of 3% may apply to all renovation work in the bathroom. PMR adaptations may also qualify for specific assistance, to be verified on a case-by-case basis depending on the household situation.

Transformation, Timelines, and Moisture Management

Transforming a bathtub into a walk-in shower is one of the most common requests received in Luxembourg; this transformation sometimes requires a floor adjustment to create the necessary drainage slope, a point that is systematically checked during the technical visit. A partial renovation can be completed in about a week, while a complete renovation with network adjustments generally takes two to three weeks, depending on the availability of the chosen materials. Properly sized mechanical ventilation and waterproofing installed according to the rules of the trade remain the two most effective guarantees against persistent moisture, with no compromises possible even when the overall budget is tight.

Permits, PMR Assistance, and Suitable Materials

No permit is required as long as the work remains interior and does not alter the building's structure or exterior appearance; however, a declaration may be necessary in a co-ownership situation if a common technical column is involved. Some public assistance in Luxembourg also supports PMR adaptations that facilitate home retention, based on conditions that depend on the applicant's personal situation; we guide you to the right contacts during the visit. Regarding materials, ceramic stoneware remains the reference for bathroom floors and walls, due to its water resistance and easy maintenance; for furniture, water-repellent materials specifically designed for wet areas prevent swelling observed with standard panels.

Entrust Your Bathroom to Avenir Rénovations Luxembourg

A bathroom is rarely renovated more than twice a decade: it is worth taking the time to think it through, from the choice of the shower tray to the placement of electrical outlets. The free technical visit remains the best way to obtain concrete advice on your space, even before discussing budget.

Our teams operate in all neighborhoods of Luxembourg City, with the same requirements for waterproofing and quality of installation, regardless of the budget involved. The first appointment is free and does not commit you to anything: it is simply an opportunity to obtain clear technical advice on your project.
