What You Are Actually Paying For
A marble project budget breaks into four distinct cost components. Most buyers compare quotes by comparing slab pricing alone. This is wrong. Slab pricing is between 25 and 40 percent of the total project cost on most luxury residential marble work. Comparing quotes by slab pricing alone produces deeply misleading conclusions about value.
The four components, with typical proportions for a luxury residential marble project:
- Slab cost (25-40% of total). The wholesale cost of the raw stone slab. Varies enormously by named stone, by grade within the named stone, and by current market dynamics.
- Fabrication cost (30-45% of total). Cutting the slab to spec, polishing/honing/leathering, carving any profiles, sealing. The labour and infrastructure cost of turning a raw slab into a finished piece.
- Install cost (15-25% of total). Site templating, delivery, installation labour, integration with surrounding architecture (plumbing for vanities and tubs, scribing to existing trim for archways and surrounds).
- Lifetime maintenance (typically 5-10% of total over a 10-year horizon). Sealing, occasional refinishing, repair of any damage. Often invisible to buyers at the spec stage.
The proportions shift significantly across application types. A simple cased opening in Carrara White might be 40 percent slab cost, 35 percent fabrication, 20 percent install, 5 percent lifetime maintenance. A carved Calacatta Gold vanity with complex profiles might be 30 percent slab cost, 50 percent fabrication, 15 percent install, 5 percent lifetime maintenance. The pattern that holds across applications is that fabrication is usually the largest single cost.
What the Stone Itself Costs
Slab cost varies by named stone, by grade, and by current market dynamics. The figures below are 2026 wholesale slab pricing in CAD per square foot, sourced from the active The Marble Atelier quarry partnerships.
| Named stone | Standard grade (CAD/sqft) | Premium grade (CAD/sqft) |
|---|---|---|
| Carrara White | pricing on request-80 | pricing on request-140 |
| Travertino Romano | pricing on request-90 | pricing on request-160 |
| Emperador Dark | pricing on request-110 | pricing on request-200 |
| Nero Marquina | pricing on request-110 | pricing on request-200 |
| Verde Guatemala | pricing on request-150 | pricing on request-280 |
| Calacatta Gold | pricing on request-150 | pricing on request-400+ |
| Statuario | pricing on request-180 | pricing on request-400+ |
| Calacatta Viola | pricing on request-250 | pricing on request-500+ |
| Sahara Noir | pricing on request-220 | pricing on request-400+ |
Several patterns: the cheapest stones (Carrara, Travertino) are roughly one-tenth the price of the most expensive stones at premium grade. The price difference between standard and premium grade within a single named stone can be three to five times. Premium-grade slabs are not just more expensive, they are also harder to source; lead times for premium Calacatta Borghini or premium Calacatta Viola can stretch to six months during peak design-press demand cycles.
Slab waste matters. The slab cost above is the cost per square foot of slab purchased, not per square foot of finished piece. A vanity that requires three square feet of finished surface might require four to five square feet of slab when waste is accounted for, depending on slab dimensions, the layout of the piece, and any veining-direction matching the design requires. Bookmatched installations have particularly high waste because slabs must be matched in pairs from the same block, often with significant unusable cutoffs.
What Turning a Slab Into a Piece Costs
Fabrication is the labour and infrastructure cost of cutting, shaping, finishing, and sealing a raw slab into a finished piece. Fabrication costs scale with complexity, not with stone value, which means a complex piece in a cheap stone can cost more to fabricate than a simple piece in an expensive stone.
The major fabrication cost drivers:
- Cutting complexity. A rectangular vanity top is the cheapest cut. A vanity with cut-outs for sinks adds cost. A piece with curved profiles adds significant cost. A bookmatched installation adds the most cost because the cutting must be precise enough to match across the joint.
- Profile complexity. See our edge profiles reference. A straight-polish profile is the cheapest. A 1/4 bevel adds modest cost. An ogee profile or a carved fluted vanity face can double the fabrication cost compared to the same piece with a straight profile.
- Finish complexity. Polished, honed, and leathered finishes have similar labour costs at standard grade. Premium polish (the mirror-like finish that requires multiple grit passes plus a polishing pad) adds modest cost. Hand-carved profiles (bas-relief, sculptural carving on Surface panels) can multiply the fabrication cost several times.
- Sealing and finishing. Standard penetrating sealer is included. Premium sealing (multi-coat, decorative finish) adds modest cost.
Indicative fabrication multipliers on slab cost:
| Piece type | Fabrication multiplier on slab cost |
|---|---|
| Simple rectangular vanity top with sink cut-out | 0.8 - 1.2x |
| Vanity with bevel or radius edge profile | 1.0 - 1.5x |
| Vanity with bullnose or basic ogee profile | 1.3 - 1.8x |
| Carved fluted vanity face | 1.8 - 2.5x |
| Cased opening with classical ogee profile | 1.5 - 2.2x |
| Bookmatched wall installation (4+ slabs) | 1.2 - 1.8x plus matching premium |
| Bas-relief sculptural panel | 3.0 - 5.0x or commission-based pricing |
So a Carrara White vanity at pricing on request/sqft slab cost with a basic radius profile might fabricate at pricing on request-90/sqft. A Calacatta Gold fluted vanity at pricing on request/sqft slab cost might fabricate at pricing on request-320/sqft. The fabrication-to-slab ratio for premium carved work can substantially exceed the raw slab cost.
GTA Full Service vs Ship-Only
Install cost depends on whether the project is GTA full-service or shipped to a contractor outside the GTA.
GTA full service install
For projects within the Greater Toronto Area, The Marble Atelier handles install with our own crew. Install cost typically runs 15 to 25 percent of total project cost and is a flat-rate price built into the quote. The major cost components are templating (one site visit, 60-90 minutes for most pieces), delivery (1-2 person crew with appropriate lifting equipment), and installation labour (typically 1 to 3 days for most pieces, longer for complex carved installations).
What's included in GTA install: site templating, delivery, installation, integration with adjacent architecture (plumbing rough-in for vanities, scribing to existing trim for archways), final sealing, lien protection, pricing on requestM general liability and WSIB coverage. See our how we work page for the full process.
Ship-only install (anywhere in Canada)
For projects outside the GTA, we ship the finished piece to your contractor or stone installer. Install cost falls into two parts: our crating and freight, plus your installer's labour.
Typical crating and freight costs by region (CAD):
| Region | Cost (CAD) | Transit time |
|---|---|---|
| Ottawa, Montreal | pricing on request | 2-3 business days |
| Quebec City, Atlantic provinces | pricing on request | 3-5 business days |
| Manitoba, Saskatchewan | pricing on request | 4-6 business days |
| Alberta | pricing on request | 5-7 business days |
| British Columbia | pricing on request | 5-7 business days |
Your installer's labour will typically run pricing on request depending on the piece and the install complexity. Most professional stone installers and high-end finish carpenters can set The Marble Atelier work without specialised training; we provide written install guides with every shipment.
For ship-only projects, total project cost (slab + fabrication + crating + freight + your installer) typically runs 5 to 15 percent less than the equivalent GTA full-service project, because you are absorbing the installer's labour at local rates. The trade is that you take on installer coordination and any risk of install variation; for most clients outside the GTA this is the better arrangement anyway because you have an existing contractor relationship.
What the Stone Costs Over 10 Years
Lifetime maintenance is the cost most buyers underestimate at the spec stage. For calcium carbonate marbles (the great majority of luxury stones), a 10-year ownership horizon includes:
- Re-sealing every 12 to 18 months. Penetrating sealer is approximately pricing on request-250 per kit; application takes 30-60 minutes for a typical vanity or surround. Over 10 years: 7-10 sealings, pricing on request-2,500 in materials and time.
- Spot etching repair. Most polished marble pieces will accumulate some etching over a decade. Light etching can be addressed with marble polishing compound (DIY, pricing on request-100 per application). Significant etching requires professional refinishing (pricing on request-1,500 per piece).
- Edge or surface damage repair. Chips, cracks, and scratches happen. Most are repairable through a combination of epoxy fill and re-polishing. Typical repair: pricing on request-1,000 per incident.
- Major refinishing. Once or twice over a 20-year ownership, polished marble may benefit from professional re-polishing of the entire surface to remove accumulated etching and surface dulling. Cost: pricing on request-5,000 per piece depending on size and complexity.
For a typical luxury Calacatta Gold vanity with a 10-year maintenance projection: available on request-5,000 in cumulative maintenance, on a piece that cost pricing on request installed. Roughly 18-35% of original install cost over a decade. Buyers who are surprised by this number usually didn't ask the question at the spec stage.
For quartzite, the maintenance cost is lower (sealing every 2-3 years, less etching repair, less refinishing): typically pricing on request-2,500 over 10 years on equivalent installation. For quartz and porcelain, lifetime maintenance is effectively zero.
A Worked Example
To make this concrete, here is a worked example for a typical luxury The Marble Atelier project: a Calacatta Gold powder room with a single-sink fluted vanity, a wall-mounted faucet, integrated marble countertop and backsplash, and a fluted Calacatta Gold cased opening into the powder room.
| Cost component | Estimate (CAD) | % of total |
|---|---|---|
| Calacatta Gold slab (~12 sqft including waste) | pricing on request | 9% |
| Fluted vanity fabrication (carved profile, sink cut-out) | pricing on request | 27% |
| Cased opening fabrication (fluted profile, two pieces) | pricing on request | 21% |
| Sealing and finishing | pricing on request | 2% |
| GTA install (templating, delivery, install, plumbing integration) | pricing on request | 16% |
| Project total at install | pricing on request | 75% |
| Projected 10-year maintenance | pricing on request-5,000 | 15-25% |
| 10-year total cost of ownership | pricing on request-20,100 | 100% |
The same project specified in Carrara White instead of Calacatta Gold would run available on request-12,500 at install (the slab cost drops by about pricing on request the fabrication drops modestly because Carrara is slightly easier to carve at standard grade) with similar 10-year maintenance.
The same project specified in honed quartzite instead of marble would run available on request-14,500 at install with much lower 10-year maintenance (pricing on request-1,500 over 10 years), bringing total cost of ownership to pricing on request-16,000.
Three honest principles for budgeting
- Budget the install cost as 60-75% of total cost of ownership. The remainder is fabrication-stage decisions you haven't made yet (which profile, which finish) and lifetime maintenance you won't see for years.
- Budget premium-grade pricing for the named stones you actually want. If you want bookmatched Calacatta Gold, budget pricing on request-400/sqft slab cost, not the pricing on request/sqft entry-level Calacatta. Slab variation within the named category is real and visible.
- Budget for the maintenance you will actually do. If you will not re-seal regularly, do not specify polished marble for high-use applications. Specify honed or specify a different material. Mismatching maintenance commitment to material choice is the single most common source of dissatisfaction with luxury stone work.
