Kitchen countertop installation cost in Luxembourg (2026)

Edge profile upcharges (per linear metre):

• Straight eased edge: included
• Bullnose / radius edge: +€18–€30
• Chamfer edge: +€15–€25
• Mitred double-thickness edge: +€55–€95
• Ogee or double bullnose: +€45–€75

Cut-out charges:

• Undermount sink: €120–€180
• Overmount sink: €60–€90
• Induction or gas cooktop: €90–€140
• Drainage grooves either side of the sink: €150–€220

Base price drivers on a quartz quote:

• Slab purchase and stock: 45–55 %
• Fabrication labour at fabricator workshop: 20–25 %
• Template + delivery + installation: 15–20 %
• Sealant, hardware, waste disposal: 5–10 %

A €2 800 net project at TVA 17 % reaches €3 276 TTC — always compare TTC.

The template step is the single most important moment of a stone-countertop project. It is taken after the base cabinets are installed and levelled, not from architect plans.

What happens during a physical laser template:

• Laser scan of cabinet tops records dimensions to ±0,5 mm
• Plumbing and electrical run-throughs are marked
• Wall squareness and out-of-plumb are captured
• Hob and sink model references are confirmed
• Edge profile, overhang and backsplash are chosen with the client
• The signed template becomes the production brief

The seven traps that cause costly errors:

• Template before base cabinets are installed — recut charges of €300–€800
• Plumbing not roughed to correct height — countertop removed for rework
• Hob swapped after template — full slab rework if cut-out differs
• Sink model changed — €150 cut-out redo plus €80 edge refinish
• Wall colour changed after template — countertop edge profile may clash
• Backsplash height decided at template but floor not yet laid — height error
• Template signed without slab-colour confirmation — dye-lot variance at install

The timing:

• Template: 1,5 hours on site
• Fabrication: 8 to 14 working days
• Delivery + installation: 3 to 4 hours on site

Ask for the template date in writing. Do not pay more than 15 % deposit before the template — the template clarifies scope and the stone-colour match, which can still cancel the project.

Included in a standard quartz quote at €3 000–€3 600:

• Physical laser template on installed cabinets
• Slab selection from fabricator's current stock
• Fabrication: cut, polish, edge profile
• Delivery to apartment door (ground floor or lift-accessible)
• Installation: levelling, sealant joints, silicone to wall
• Basic silicone-seal joint at wall and backsplash return
• Removal of protective wrap and worksite tidy-up
• 5- to 10-year fabricator warranty on material (varies)

Commonly excluded — watch for separate lines:

• Plumbing reconnection after install: €120–€250
• Sink supply (the sink itself): €150–€900 depending on model
• Tap supply: €150–€700
• Cabinet reinforcement for heavy stone: €100–€250
• Countertop removal of the old one: €180–€450
• Stair delivery surcharge (2+ floors, no lift): €120–€300
• Integrated sink (stone sink made from the same slab): €600–€1 400 extra
• Templating for back-to-back cut on natural stone (book-match): +25 %

Hidden traps:

• Slab selection — some fabricators bill per-visit for slab-yard trips
• Rush fabrication — +15–25 % for sub-8-day turnaround
• Remnant discount — if a 6 m job uses a slab that leaves a large offcut, ask the fabricator for a 5–10 % discount
• Cracked slab on delivery — rare but insurance is in the installer's scope, not yours

A countertop installation in a kitchen renovation is eligible for the reduced TVA 3 % on the labour portion if the property is the owner's primary residence held for more than 2 years. The stone itself remains at TVA 17 %.

Rate in practice:

• Laminate or solid-wood countertop installed in a principal residence > 2 years old: labour TVA 3 %, material TVA 17 % if a split is feasible, otherwise blended 17 %
• Stone countertop in primary residence: same pattern — slab 17 %, fabrication+installation labour eligible for 3 % via signed logement.lu declaration
• New build within 2 years: TVA 17 % on everything
• Rental property: TVA 17 % regardless
• Second residence: TVA 17 % regardless
• Home office part of the kitchen: TVA 17 % pro rata

The split invoice pattern for a primary residence:

• Slab and material line: net + TVA 17 %
• Fabrication labour: net + TVA 3 % (eligible)
• Template, delivery, installation labour: net + TVA 3 % (eligible)
• Accessories (sink, tap if supplied by installer): net + TVA 17 %

Worked example on €2 800 net, 40 % slab / 60 % labour:

• Slab €1 120 + TVA 17 % €190 = €1 310
• Labour €1 680 + TVA 3 % €50 = €1 730
• Total: €3 040 TTC vs. €3 276 TTC at full 17 %
• Saving: €236

Request the declaration logement before signing. The installer must issue the split invoice and retain the signed declaration on file.

Installers segment clearly: kitchen retailers with in-house fabricators, independent stone fabricators, and big-box DIY chains. Their pricing logic and warranty depth differ.

The six checks that matter:

• Slab brand and thickness. 20 mm quartz is lighter but less robust than 30 mm; confirm brand (Silestone, Caesarstone, Dekton) and thickness in writing.
• Fabricator origin. Local LU fabricator, Belgian, German, or Italian shop-cut? Origin drives lead time and warranty-claim ease.
• Edge profile and cut-outs. Get the specific profile names (pencil, bullnose, mitred) and cut-out count in the quote.
• Warranty. 5 years minimum on material + 2 years on installation workmanship is standard; 10 years signals premium fabricator.
• Delivery and stair access. Surcharges for upper floors without lift must be in the initial quote, not added later.
• TVA position. 3 % on labour with logement declaration, 17 % on slab — spelled out.

Briefing pack to send each installer:

• Kitchen layout sketch with dimensions
• Current cabinet brand and height
• Preferred material segment and budget ceiling
• Sink, tap, hob model references
• Target install date

Typical quote spread on a 6 m quartz project:

• Kitchen retailer with in-house fabricator: €3 400–€4 200 (convenience, full accountability)
• Independent stone fabricator: €2 800–€3 600 (best value, requires coordination)
• Big-box DIY chain with installer: €3 200–€3 800 (mid-market, variable warranty)

Quotes on the same brief cluster within ±15 %. A 30 % gap usually means slab brand or thickness is different — read the small print before picking the cheapest.
