Price breakdown by tile format and finish
| Component | Price TTC |
|---|---|
| Demolition of existing shower (tray, tiles, waterproofing) | €280–€520 |
| Substrate repair and screed slope for floor drain | €180–€380 |
| Liquid waterproofing to EN 14891 (SMP or PU) on 8 m² | €220–€380 |
| Sheet membrane (PE) alternative on 8 m² | €280–€440 |
| Ceramic tile, 20 × 20 cm, supply only | €25–€45/m² |
| Porcelain, 60 × 60 cm, supply only | €45–€90/m² |
| Porcelain, 120 × 60 cm large format, supply only | €75–€140/m² |
| Mosaic, glass or stone, supply only | €85–€220/m² |
| Tile installation (labour only) | €55–€85/m² |
| Large-format surcharge (> 90 cm long edge) | +€15–€25/m² |
| Linear drain (caniveau) stainless | €180–€420 |
| Floor drain (bonde classique) | €60–€140 |
| Silicone + trim profiles | €120–€220 |
Typical LU projects all-in:
- Entry ceramic, 20 × 20, floor drain, classic walk-in: €1 800–€2 400
- Mid-range porcelain, 60 × 60, linear drain, walk-in: €2 600–€3 400
- Premium large-format, mosaic feature, linear drain, curbless: €3 800–€4 800
- Full bathroom re-tile (not just shower) on 6 m² bathroom: €5 200–€8 500
What moves the budget:
- Tile format — large-format (>90 cm) demands perfectly flat substrate and raises labour 25–35 %
- Waterproofing system — sheet membrane more expensive but more tolerant; liquid systems need skilled application
- Drainage type — linear caniveau is €200–€300 more than a point drain but enables true curbless entry
- Mosaic or feature wall — takes 3× longer to lay than field tile
- Pattern — herringbone or diagonal pattern adds 20–30 % in labour and 10 % in material waste
- Access — 4th floor walk-up with no lift adds €150–€280 for porter labour
Waterproofing — the layer that decides success
A shower lives or dies on the waterproofing layer behind the tiles. Luxembourg building codes, in line with DTU 43.1 and European standard EN 14891, require a waterproof layer on the floor and up to 2,1 m on walls in wet zones. Skipping or under-specifying this layer is the #1 cause of bathroom leaks in the first 5 years.
Two waterproofing systems in LU use:
Liquid-applied membrane (SMP, PU, or acrylic-based):
- Brushed or rolled onto substrate in 2 coats, 800 to 1 200 g/m² total
- Cures in 12–24 hours between coats, 48 h before tiling
- Self-terminates at corners with reinforcement fabric
- EN 14891 CM O2 P minimum class for showers
- Pros: Fast, cheap, adaptable to any shape
- Cons: Requires uniform application thickness; thin spots fail
Sheet membrane (PE or composite):
- Factory-made sheet bonded to substrate with adhesive
- Overlapped and sealed at joints with pre-formed corners
- Manufacturer's system (Wedi, Kerdi) with pre-cut shower boards is common on LU walk-ins
- Pros: Immediately waterproof, no curing wait, tolerates substrate flex
- Cons: 25–40 % more expensive; joints must be faultless
What a proper waterproof sequence looks like:
- Substrate cured and dust-free
- Primer on absorbent substrate
- Reinforcement strip at all corners, floor-wall and wall-wall
- 2-coat liquid application or sheet-membrane bonding
- Flood test: seal drain, fill to 3 cm for 24 h, observe no seepage
- Tile laid over the cured membrane with flexible S1 adhesive
Red flags in a devis:
- No mention of EN 14891 class or manufacturer name
- "Etanche" as the only description — meaningless
- No flood test line item
- Waterproofing coat thickness in "litres" without m² coverage
- Proposal to use standard ceramic adhesive as the waterproof layer — unsafe
LU insurance context:
- Damage from a failed shower waterproofing is a claim versus the tiler's décennale, covering full repair for 10 years
- An undeclared tiler has no décennale — the owner bears the full cost of strip-out and redo
- Insist on décennale attestation before signing; a declared LU tiler will provide it without being asked
Curbless walk-in or raised lip — design and cost impact
The design choice between a curbless walk-in (à l'italienne, 0 cm threshold) and a raised-lip shower (3–5 cm threshold) drives both the construction complexity and the lifetime usability. Luxembourg accessibility trends and the aging demographic make curbless increasingly the default in new bathrooms.
Curbless walk-in:
- Floor slopes uniformly toward a linear drain (caniveau) or central point
- Requires 1,5 % minimum slope on the floor (15 mm per metre)
- Screed is recessed 25–40 mm before tiling to accommodate slope and tile thickness
- Adds €400–€800 to the base shower budget (extra screed work, linear drain)
- Future-proofs the bathroom for reduced mobility
- Requires tile thicknesses and drain depths carefully planned on the devis
Raised-lip shower (3–5 cm threshold):
- Classic cabin or walk-in with small tiled step or aluminium profile at entry
- Simpler substrate — level screed, standard floor drain at centre
- €1 800–€2 800 all-in typical range
- Easier for retrofit where the screed thickness is constrained
- Less comfortable long-term but keeps water more reliably contained
Accessibility (PMR) compliance:
- True PMR shower requires 0 cm threshold + 120 × 120 cm minimum floor + grab bars with 300 kg load rating
- PMR conversion subsidies available via Fonds national de solidarité up to €3 600
- A PMR shower in a primary residence at TVA 3 % with subsidy can reduce net cost by €2 500–€4 500
When to choose which:
- Curbless: new-build, bathroom remodel where screed is being redone, households with accessibility needs
- Raised-lip: quick shower replacement only, tight budget, no need to touch the floor slab
Drain placement in curbless design:
- Linear drain at one wall — cleanest look, easiest slope control, slightly higher cost
- Linear drain across threshold — most accessible, demands perfect slope calibration
- Central point drain — cheapest but creates four slopes that must all meet at the drain
LU reality check:
- Most LU bathrooms built 1980–2010 have a 25 mm screed that is too thin for curbless conversion
- Converting these often requires cutting the slab 30–40 mm deeper (€600–€1 200 extra)
- Post-2015 screeds are usually thick enough
TVA 3 % eligibility and bathroom renovations
Shower retiling in an owner-occupied primary residence qualifies for the 3 % super-reduced TVA rate via the logement.lu procedure when the dwelling is at least 20 years old at invoice date. On a €3 500 project, the saving versus standard 17 % is €490 — material money on a modest renovation.
Qualifying conditions:
- Primary residence, owner-occupied
- Dwelling at least 20 years old at invoice date
- Tiler holds Autorisation d'établissement
- Work is filed on logement.lu before the first invoice
- Lifetime cap €50 000 per dwelling per owner on cumulative 3 %-eligible work
Worked example — €3 500 shower retile:
- Net HT: €3 500
- TVA 3 %: €105
- TTC: €3 605
- TVA 17 % standard: HT €3 500 + €595 = €4 095
- Saving: €490
Typical LU bathroom-renovation cumulation:
- Shower retile: €3 500
- New toilet and vanity: €1 800
- Floor retile: €2 200
- Plumbing updates: €1 500
- Total 9 000 € — well under the €50 000 lifetime cap per owner
Coordinating multiple trades under 3 %:
- Each trade (tiler, plumber, electrician) files their own logement.lu reference
- The dwelling's cumulative cap tracks across trades on the same owner
- Keep a master sheet of all 3 %-eligible invoices
TVA 17 % applies instead:
- Rental property
- Second residence
- New-build under 20 years outside its original logement.lu track
- Commercial premises
Three red flags:
- Tiler says "I do TVA 3 % but not via logement.lu" — incorrect, the 3 % rate only flows via logement.lu filing
- Devis shows TVA at 3 % with no logement.lu reference number — not compliant
- Tiler refuses to apply the 3 % rate saying "it takes too long" — find another; declared professionals do it routinely
Required documentation after the job:
- Final invoice citing logement.lu reference number
- Copy of waterproofing system datasheet
- Décennale attestation covering the specific work
- Keep all three for 10 years
Timeline and what to expect on site
A shower retile in Luxembourg is a 5 to 9 working-day project end-to-end. The schedule is driven by cure times, not labour hours — patience is the cheapest material on a tiling job.
Typical 7-day schedule:
- Day 1 — demolition (old tiles out, old waterproofing off, old drain removed, substrate assessed)
- Day 2 — substrate repair, levelling screed, slope shaping if curbless
- Day 3 — screed cure day (no work)
- Day 4 — primer and first coat waterproofing
- Day 5 — second coat waterproofing, corner reinforcement, flood test
- Day 6 — tile installation (floor + walls)
- Day 7 — grouting, silicone, clean-up, handover
When the schedule stretches:
- Curbless conversion requiring slab cutting: +2 days
- Large-format tile (120 × 60 cm) requiring precise substrate prep: +1 day
- Mosaic feature wall: +1 day
- Sheet membrane instead of liquid (extra detailing at corners): +0,5 day
- Humid winter conditions slowing cure: +1 day
What you do during the project:
- Arrange alternative shower access (hotel, neighbour, other bathroom)
- Be available on day 1 for final design confirmation
- Be available on day 6 for tile layout sign-off (before fixing)
- Inspect at handover with installer present
What can go wrong on site:
- Hidden rot in substrate discovered on day 1 — usually adds 1 day and €180–€380
- Old drain pipe discovered to be undersized or defective — plumber coordination adds 1–2 days
- Tile delivery delayed by distributor — installer cannot start day 6; reschedule may add 3–5 days
Commissioning and use:
- Fully functional use starts 24–48 hours after silicone is laid
- Grout takes 7 days to reach full cure — avoid heavy cleaning in the first week
- First professional clean with pH-neutral cleaner only for 30 days
- Silicone joints need annual inspection; replace at 5-year mark for the best long-term result
Typical owner costs beyond the tiler bill:
- Shower fixture if replacing (mixer, head): €150–€600 at supply, plus plumber fee
- Shampoo shelf, grab bars, niches — specified separately if not in the tiler devis
- Bath mat on bathroom floor — cheap safety investment
Comparing three tiler quotes
Three tiler quotes on the same 2 m² walk-in shower can arrive at €2 000, €2 800 and €3 900 TTC. The spread is almost always scope drift, waterproofing class, and undeclared vs declared labour.
Brief to send three tilers:
- Shower dimensions and orientation (floor m², wall m²)
- Current condition (existing cabin, tiled, needs demolition yes/no)
- Target tile (brand, format, finish)
- Preferred waterproofing system (liquid SMP or PU, or sheet membrane)
- Drain type (linear caniveau or central bonde)
- Curbless or raised lip
- TVA line (3 % logement.lu or 17 %)
- Start-date window
Quote-comparison checks:
- Waterproofing line in m² and class — EN 14891 CM O2 P class, coat thickness, brand named
- Flood test line item — explicit in the devis, not implied
- Tile brand and format — "Marazzi Grande Resin 60 × 60" is comparable to the same from another installer, not to "generic porcelain"
- Prep breakdown — demolition in m², screed in m², primer in m² — transparent
- Drain model and brand — "Wedi Fundo Riolito, 800 mm linear" is specific
- Décennale attestation — by name and policy number, not "we have insurance"
- TVA line — 3 % or 17 % with logement.lu reference if 3 %
- Labour rate breakdown — fixed per m² is normal; per-hour rate without m² estimate is a warning sign
Red flags:
- Prices below €1 500 for a 2 m² walk-in — cuts corners on waterproofing or labour
- "All-in" quote with no waterproofing brand or class
- Cash discount offered — signals undeclared
- No mention of décennale
- Tiler insists on own-source tile with no brand — likely low margin reseller adding markup
Tight-brief convergence:
- Three declared tilers on the same brief typically land within ±15 % TTC
- A 30 % gap usually means different waterproofing class (CM vs CM O2 P), or different tile grade
- A 40 %+ gap usually means cash-labour pricing vs declared pricing
What the tiler cannot cover:
- Plumbing-side failures (leaking pipes behind wall) — that is the plumber's décennale
- Mixer or valve failure — manufacturer's warranty
- Grout darkening over time — normal ageing, not a defect
Tiling a shower in Luxembourg costs €1 800 to €4 800 all-in for a 2 m² walk-in in 2026, with waterproofing to EN 14891, a choice of linear or point drain, and tile from 20 × 20 cm ceramic to 120 × 60 cm large-format porcelain. The waterproofing system is where quality is made or broken — insist on a named brand, a class on the devis, and a flood test line item. TVA 3 % via logement.lu is available on primary residences 20+ years old, saving €490 on a €3 500 project. Hire only declared tilers with Autorisation d'établissement and décennale cover. Fynd.lu lists tilers in every LU region — request three quotes on a shared brief before signing.
