Shower tiling cost in Luxembourg (2026)

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

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:

1. Substrate cured and dust-free
2. Primer on absorbent substrate
3. Reinforcement strip at all corners, floor-wall and wall-wall
4. 2-coat liquid application or sheet-membrane bonding
5. Flood test: seal drain, fill to 3 cm for 24 h, observe no seepage
6. 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
• Ask whether the tiler holds décennale insurance (not compulsory) and, if so, get the attestation before signing

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

Shower retiling in a primary residence (owner or tenant) qualifies for the 3 % super-reduced TVA rate when the dwelling is at least 10 years old at the start of the works. On a €3 500 project, the saving versus standard 17 % is €490 — material money on a modest renovation.

Qualifying conditions:

• Main residence of the owner or a tenant
• Dwelling at least 10 years old at the start of the works, or works within 5 years of purchase
• Tiler holds Autorisation d'établissement
• For 3 % directly on the invoice, work approved by the AED before works start; otherwise 17 % is invoiced and the difference is reclaimed
• Cap of €50 000 of VAT advantage per dwelling 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 — at most about €1 260 of VAT advantage (14 %), far under the €50 000 cap per dwelling; the vanity unit counts as bathroom furniture and stays at 17 %

Coordinating multiple trades under 3 %:

• Each trade (tiler, plumber, electrician) cites the AED approval reference
• The dwelling's €50 000 cap tracks across all trades
• Keep a master sheet of all 3 %-eligible invoices

TVA 17 % applies instead:

• Dwelling that is nobody's main residence
• Second residence
• New-build under 10 years outside its original TVA-logement track, unless the works are completed within 5 years of buying it
• Commercial premises

Three red flags:

• Tiler says "I invoice TVA 3 % without any AED approval" — incorrect, 3 % directly on the invoice requires prior AED approval
• Devis shows TVA at 3 % with no AED approval reference — 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 AED reference number
• Copy of waterproofing system datasheet
• Décennale attestation covering the specific work
• Keep all three for 10 years

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

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 % (AED-approved) 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 the AED approval 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
