Bathtub refinishing cost in Luxembourg (2026)

A €450 quote with TVA at 17 % becomes €526.50 all-in. If the refinishing is invoiced as part of a qualifying bathroom renovation on a principal residence, the super-reduced rate of 3 % can apply on the same line — worth coordinating with the contractor before the devis is signed.

Format drivers:

• Surface area: a standard 170 cm tub takes roughly 4 to 5 working hours on site plus a 24-hour cure; a 180 cm corner tub or a freestanding clawfoot takes 6 to 8 hours with the same cure window, pushing the quote by €80–€150
• Existing coating: a previously refinished tub that is peeling must be chemically stripped before the new coat — typically a €100–€180 add versus a first-time refinish
• Access and masking: a tub in a tight alcove with low tiling above is faster to mask than a freestanding piece that must be protected on all sides, which adds 1 to 2 hours
• Ventilation: two-component coatings release solvents during the cure; a windowless bathroom requires an extractor fan rental or air scrubber, an €80–€150 line in some devis

The ratio of one to two and a half between the bottom and top of the range is not a margin game — it tracks hours on site, materials consumed and the risk of a redo if the prep is rushed. A proper on-site survey before the devis pins the project at the correct point.

The six drivers that matter:

• Tub material. Acrylic is forgiving and etches lightly; cast iron needs mechanical roughening plus a bonding primer. Cast iron adds €80–€150 in material and an extra prep hour.
• Condition of the existing surface. Chalky dulling that responds to a simple sand is the easy case. Chip repair, spider-crack fill and rust scab neutralisation each add €40–€100 and can push a tub out of the flat-fee tier into an hourly top-up.
• Coating system. Single-component polyurethane is the entry product at €250–€350 total. A two-component epoxy with a branded warranty (e.g. Ekopel, Bathworks Pro) carries a 3 to 5-year guarantee and sits at €400–€600.
• Drain and overflow hardware. Refinishing with the drain and overflow in place masks them and accepts a visible line; removing, storing and refitting them costs €60–€120 in labour but yields a cleaner edge.
• Access and floor protection. Apartments on upper floors where the team must carry kit up a narrow stair and protect carpeted communal areas add €50–€100.
• Commune and travel. Communes within 20 km of Luxembourg-Ville — Strassen, Bertrange, Hesperange, Bridel — are at the quoted rate. Sites in the north (Wiltz, Clervaux, Vianden) add a €40–€90 travel line.

The written devis is the contract — read line by line before signing. Anything not listed is almost always billed on top.

Typically included in a €350–€500 quote:

• Surface degrease and light mechanical abrasion
• Chip repair up to three points with epoxy filler
• Masking of tiles, floor, fittings and vanity
• Two coats of the quoted coating system
• Reinstallation of any hardware that was removed
• A one-year labour warranty on peeling, blistering or bond failure
• Removal of the site protection and a cleaned handover

Typically excluded — priced as an extra if the survey flagged them:

• Replacement of the drain or overflow if corroded through
• Full strip of a previously refinished coat (€100–€180)
• Silicone joint around the tub rim (€40–€70 in labour and materials)
• Tile repair or re-grouting adjacent to the tub
• Non-slip base treatment (€60–€120) — strongly recommended for family use
• Plumbing isolation if a pressure test is needed before the coat

What a proper devis should list explicitly:

• The tub material and dimensions as measured on site
• The coating brand and reference, not just "two-component coating"
• The warranty duration and what voids it (harsh cleaners, abrasive pads)
• The drying and return-to-service timing — usually 24 hours to dry, 72 hours before first bath
• Payment terms and the TVA rate applied (17 % standalone, 3 % if bundled into a qualifying renovation)

Refinishing sits in an interesting zone between standalone maintenance and bathroom renovation, and the TVA treatment hinges on which side the invoice falls on.

The three TVA scenarios in Luxembourg:

• Standalone maintenance on any bathroom. The service carries the standard 17 % TVA. A €400 net quote is €468 all-in.
• Part of a qualifying renovation on a principal residence. Where the refinishing is line-itemed inside a broader bathroom renovation that meets the conditions for the super-reduced 3 % rate (primary residence, property older than 20 years, declared contractor applying for the rate via Administration de l'Enregistrement et des Domaines), the refinishing line can carry 3 %. A €400 net line becomes €412 all-in — a saving of €56 on that single line.
• Rental properties and secondary homes. The 3 % rate does not apply — the standard 17 % is the norm.

Declared labour is the only legally safe option. Cash-in-hand refinishing is a common grey-market offer because a single contractor with a kit and a day of work produces a finished result. Risks for the household:

• No written warranty if the coat peels within six months
• No professional-liability cover if solvent stains a tile or a wood floor
• No recourse through Union Luxembourgeoise des Consommateurs (ULC) in case of dispute
• Possible liability exposure if the ITM (Inspection du Travail et des Mines) audits the site

Checks before signing a devis:

• The Autorisation d'établissement number, which should appear on the header of the devis
• A Luxembourg TVA number (LU followed by eight digits)
• A fixed address in Luxembourg, not only a mobile number
• Professional-liability insurance certificate on request — standard coverage is €1 million per claim

Refinishing is the correct call when the tub body is sound and you like its size, shape and position. Replacement is the correct call when the body is compromised or the bathroom layout is being rethought anyway. Five signals sort the two cases.

Signal 1 — through-cracks or rust scabs under the enamel. A hairline surface crack can be filled. A crack you can feel with a fingernail or a rust patch bulging under the existing finish means the substrate is failing. Refinishing buys you six to twelve months at most — replace.

Signal 2 — the tub size or position no longer works. A 160 cm tub in a bathroom that would fit a 180 cm model, or a corner tub you would swap for a walk-in shower, is not a refinishing case. You are buying a different bathroom.

Signal 3 — plumbing ageing at the same time. If the drain trap is galvanised steel from the 1970s and shows corrosion at the joint, the floor behind and the tile row below the tub will need work soon. Do the work once, not twice.

Signal 4 — the surface has been refinished once already. A factory enamel takes a refinish coat well. A previous refinish takes a second refinish only if the first is fully stripped — often at a cost within €100 of a replacement.

Signal 5 — budget and disruption tolerance. Refinishing: €250–€600, one day on site, 72 hours before the first bath, no tile disturbance. Replacement: €1 500–€4 000, three to five days on site, tile work around the new tub, a skip or evacuation slot for the old unit.

When signals 1, 2 or 4 trigger, replace. When only signal 5 is in play, refinish.

Refinishing devis are easy to compare when the brief is identical. Send all three providers the same short specification and they will land within ±15 % of one another on the price line.

The six checks that matter:

• Coating brand and system. Not "two-component coating" but a named product — Ekopel 2K, Bathworks Pro, Armatec. Each has a datasheet, a cure schedule and a warranty from the manufacturer.
• Coat count. Two coats is the minimum for durability. A single-coat offer at the bottom of the range is a red flag — it will not hold past twelve months on a bath used daily.
• Included repairs. How many chips, how many hairline cracks, up to what size. An offer that reads "minor repairs included" without a number will surface as an extra on the day.
• Warranty duration and exclusions. One year covers peeling and bond failure on most budget offers; three to five years is possible with Ekopel or Armatec. Read the exclusions — abrasive cleaners, metal fittings stored on the tub, suction mats often void coverage.
• Cure and return-to-service time. 24 hours is typical; some systems cure faster at a slight premium. If you have only one bathroom, this drives scheduling.
• TVA treatment and rate. All three providers on the same TVA assumption — 17 % standalone or 3 % inside a renovation — not a mix.

A clean briefing message to send to all three:

• Tub material, length, width and depth measured with a tape
• Two or three photos at good light showing the worst area
• Whether a colour change is wanted (white to grey, to anthracite)
• Whether a non-slip base is required
• Whether the work is standalone or part of a wider bathroom renovation

Quotes inside ±15 % of one another are competitive. Spreads of 2× or more almost always trace back to one provider reading the brief differently — worth a phone call before going with the cheapest.

A two-component coating reaches surface dryness in 24 hours and full chemical cure in 72 hours. The first 72 hours set the life expectancy of the finish — rushing the schedule is the single most common cause of warranty claims.

The cure schedule that matters:

• Hours 0 to 24: do not touch the surface, keep pets and children out, leave the bathroom door open and a window cracked for solvent off-gassing
• Hours 24 to 48: light touch only, no water, no standing items, no suction mats, no shampoo bottles
• Hours 48 to 72: cold-water rinses acceptable, no baths, no bubble bath, no abrasive products
• Day 4 onwards: full use, but follow the cleaning rules below for the warranty to stand

The daily-use rules that preserve the finish:

• Clean with a soft cloth and a pH-neutral bathroom cleaner — no bleach, no acid descaler, no powder abrasives
• No suction-cup mats left in place between baths — the vacuum seal lifts the coating over months
• Store shampoo bottles and bath toys on a shelf, not on the tub lip — metal fittings dropping onto the floor of the tub chip the new coat
• Rinse the tub after use to clear soap residue — a weekly deep clean with a soft cloth is enough

Signs of a bad refinish in the first six months — flag under warranty:

• Yellowing in patches (UV-sensitive coating, should be replaced by installer at no cost)
• Peeling at the edges (prep failure on adhesion)
• Soft or tacky areas after 72 hours (mixing ratio error)
• Pinholes or crater marks on the lower surface (moisture in the substrate)

A reputable refinisher will attend a warranty call within ten working days and repair or recoat at their cost under the one-year clause. Document the issue with photos and a dated note before the first call.

How long does a proper refinish last? A two-component epoxy on a prepared cast-iron or steel-enamel tub holds up for 7 to 12 years of daily family use. Budget polyurethane on acrylic lasts 3 to 5 years. Life expectancy drops sharply with abrasive cleaners and suction mats.

Can I refinish the tub myself with a kit from the DIY store? A €70 kit produces a visible result on day one and peels within 12 to 18 months on a bath used daily. The professional version costs six to ten times more because the coating, the prep and the solvent-handling are different. For a tub you plan to keep for a decade, the professional route is the only rational choice.

Will refinishing hide existing damage? No. Deep chips, cracks and rust are repaired before the coat but the repair is visible as a subtle outline under raking light. A tub with one or two repairs refinishes to a better-than-new look. A tub with ten repairs shows them all.

Is the coating food-safe for children's baths? All reputable two-component systems — Ekopel, Bathworks Pro, Armatec — carry EU certification for contact with drinking water and extended skin exposure after full cure. Respect the 72-hour cure window before the first bath.

Does the finish change the colour of the tub slightly over time? Yes, by a small amount. White coats warm slightly toward cream after 3 to 4 years; grey and anthracite are far more colour-stable. If a pure-white look matters, budget for a refresher coat at year five — typically €180–€260 if the base layer is sound.

Is an Autorisation d'établissement strictly required for a refinisher? Refinishing falls under the broader "Installateur" or "Plafonneur-Façadier" trade licences in Luxembourg. A declared contractor invoicing with TVA and a written warranty is the safe profile. Ask for the licence number on the devis.
