Bathroom renovation budget: compare quotations in Luxembourg
Published on 31 July 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
Floor area alone cannot price a bathroom: replacing fixtures in place differs from renewing pipework. Without dated, comparable local quotations, an average price would not be reliable. Build a checkable budget from the offers you receive instead.
The essentials in 30 seconds
- Give each company the same plan and equipment list.
- Separate fixed work, options and conditional work.
- Check VAT on each item, especially furniture and mirrors.
- Do not deduct support before eligibility is confirmed.

Define what will actually change
List retained, removed and replacement fixtures. State affected floor and wall areas, any shower or toilet relocation, known substrate condition, and electrical or ventilation work. Attach photographs and a plan. The company can distinguish work it can price from matters needing inspection.
| Surface | Gamme entrée | Gamme milieu | Gamme haut |
|---|---|---|---|
| 3-5 m² (petite salle de bains) | 6 000 – 8 000 € | 8 000 – 11 000 € | 11 000 – 14 000 € |
| 5-8 m² (standard) | 8 000 – 11 000 € | 11 000 – 16 000 € | 16 000 – 22 000 € |
| 8-12 m² (familiale, double vasque) | 12 000 – 16 000 € | 16 000 – 22 000 € | 22 000 – 32 000 € |

Build a comparison grid
Record protection and removal, waste disposal, plumbing, substrate preparation, waterproofing, finishes, equipment and installation, electrical work, ventilation and cleaning. Mark each line included, excluded or unclear, with amount and references. A fixed price remains comparable when its scope is explicit.
Compare options meeting the same brief
Price retained versus relocated pipes, tiled shower versus tray and alternative equipment references separately. Clarify quantities, supply, delivery and installation. A premium range label does not identify a product. A cost-per-area ratio is not a quality or abuse threshold.
Handle unknowns before signing
List matters only visible after removal, how repairs will be priced and how written approval is obtained before extras. Clarify potential storage, return and repeat-delivery charges. Set a reserve based on identified risks rather than a supposedly compulsory percentage.

Request a quoteCheck VAT by item
Housing VAT relief has conditions and requires approval for direct application. Guichet.lu includes eligible sanitary equipment but excludes furniture and mirrors from that category. A vanity unit therefore needs a clear breakdown; do not assume one reduced rate applies to the entire bathroom.
Examine support without promising it
The improvement grant for older homes can cover bathroom or toilet equipment subject to housing, income and work conditions; purely decorative improvements are excluded. Long-term care adaptations require assessment and AEC approval before work. Ask each body what applies before reducing the amount to finance.
Turn the price into a payment plan
Add accepted work, purchases you must make and explicitly excluded expenses. Compare the tax-inclusive total with deposits and payment dates. Clarify offer validity, price adjustment and consequences of changes. Keep rejected options to explain how the total evolved.
Frequently asked questions
What average cost per square metre should I use?
No documented local average is established here. The ratio conceals pipe condition and equipment choices.
Is a single fixed price always bad?
No. Scope, references, exclusions and conditions must allow comparison.
Does reduced VAT cover furniture and mirrors?
Guichet.lu excludes them from eligible sanitary equipment. Clarify their treatment separately.
Can an ordinary renovation receive support?
Some sanitary work may qualify for the improvement grant under conditions. Decoration alone is insufficient.
How do I compare quotes with and without VAT?
Request the tax breakdown and tax-inclusive total for the same scope. Check assumptions behind any reduced rate.
