Infinity White quartzite countertops typically cost $90-$175 per square foot installed, with many projects landing near $125 per square foot. Slab size, stone grade, fabrication details, local labor, and whether old counters need removal can shift the final price substantially.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed countertop | $90 per sq ft | $125 per sq ft | $175 per sq ft | Stone, fabrication, and standard installation |
| Stone material | $55 per sq ft | $85 per sq ft | $130 per sq ft | Varies by slab grade and availability |
| Typical 40-sq-ft kitchen | $3,600 | $5,000 | $7,000 | Before unusual demolition or structural work |
| Full slab purchase | $1,500 | $2,500 | $4,000 | Approximate slab price; dimensions vary |
Infinity White Quartzite Countertop Price by Project Size
For a standard kitchen with about 30-45 square feet of countertop, installed Infinity White quartzite commonly totals $3,000-$7,900. A smaller 15-25-square-foot vanity or kitchenette may cost $1,350-$4,375, although fabricators often apply a minimum project charge that raises the effective per-square-foot price.
A useful planning rate is $90-$175 per square foot installed, with $125 per square foot a reasonable midpoint for standard work. The range assumes natural stone, template-based fabrication, ordinary edge treatment, and accessible installation. Premium slab selection, extra cutouts, full-height backsplash, or difficult access can move a quote above the typical range.
Material may be sold by the slab rather than by the area used. A slab is often roughly 45-65 square feet, but dimensions and usable yield differ. A small counter can therefore require buying more stone than its finished area suggests, especially when the pattern must be matched or the layout has several separate pieces.
Assumptions: U.S. pricing in USD, standard 3-cm stone, ordinary access, and no major plumbing or cabinet changes.
How Slab, Fabrication, and Installation Shape the Quote
Stone invoices combine the slab, shop work, installation, and sometimes delivery or removal. Ask whether the quote is based on finished square footage or includes the full slab purchase; the distinction matters when remnants cannot be reused or the pattern limits cutting options.
| Quote component | Typical price | What it covers | Common price change |
|---|---|---|---|
| Quartzite slab | $55-$130 per sq ft | Stone selected for the project | Grade, origin, and available inventory |
| Fabrication | $20-$45 per sq ft | Cutting, polishing, and ordinary edge work | Complex shapes or premium edge profiles |
| Installation labor | $10-$25 per sq ft | Setting, leveling, joining, and securing tops | Stairs, long carries, or tight access |
| Sink and cooktop cutouts | $150-$350 each | Cutting and finishing an opening | Cutout type and reinforcement needs |
| Delivery and disposal | $150-$600 total | Local transport and old-counter removal | Distance, weight, and disposal requirements |
Fabricators may quote labor as a total instead of a square-foot rate. For a small job, minimum labor charges can make the cost per square foot look high; for a large kitchen, mobilization and delivery may be spread across more surface area. Clarify whether taxes, sealer, sink mounting, and backsplash pieces are included.
When labor is billed separately, a rough check is 6-12 crew-hours at $50-$100 per worker-hour, depending on crew size and site conditions.
Why Slab Thickness, Veining, and Layout Change Pricing
Stone selection is a major variable. A more uniform slab with fewer visible fissures or a preferred white-and-gray pattern may be priced above ordinary inventory. Because natural stone varies, buyers should inspect the actual slab rather than rely only on a small sample or a product name.
Layout and usable yield can affect the material bill as much as the countertop’s measured area. A 40-square-foot kitchen may need one large slab or two smaller slabs, depending on dimensions, direction of veining, and the number of separate runs. A waterfall island or bookmatched pattern can require additional stone to align the visual design.
Thickness also affects handling and finish work. Standard 3-cm quartzite is commonly priced within the ranges above. A 2-cm option may need a built-up edge or additional support, while a thickened mitered edge can add roughly $20-$50 per linear foot. Confirm whether a quoted edge price includes the labor and extra material.
Cutout count and shape matter. One standard undermount sink cutout may add $150-$350; a cooktop opening can be similar. Curves, corner notches, narrow strips, and seams near a sink require more shop time and may increase breakage risk. A complex island can cost more than a larger, simple rectangular counter.
Site conditions are another cost driver. An installation on an upper floor without elevator access, a long carry from the truck, or a narrow stairway may add $200-$800 for extra handling. If cabinets need leveling or reinforcement, carpentry may add $200-$1,000 or more, depending on the repair.
How to Lower the Quartzite Price Without Changing the Stone
Keep the layout efficient. Fewer separate runs, straight edges, and cutouts placed away from tight corners generally reduce fabrication time and waste. If the project includes a large island, ask the fabricator to show how the pieces fit on the selected slab before approving the layout.
The most controllable savings usually come from simpler fabrication and a clear scope, not from assuming the cheapest slab quote includes everything. A standard eased edge costs less than ornate profiles, and a short backsplash can cost less than full-height stone behind the entire counter. Compare the visual benefit with the additional stone and installation charges.
Request an itemized quote from at least three local fabricators using the same slab, edge, cutouts, and removal requirements. Ask whether remnants from the purchased slab can be used for a small vanity or shelf. This may reduce waste, although the fabricator may still charge for cutting, polishing, and installation.
Prepare the site before the crew arrives. Empty cabinets, clear the access route, and coordinate sink, faucet, and cooktop details in advance. Avoid changing appliance dimensions after templating, since revisions can lead to recutting, another trip, or a delayed installation.
Where U.S. Stone Countertop Quotes Run Higher or Lower
Local labor, stone distribution, and transportation affect the price. In major coastal metros and high-cost cities, installed bids may run about 10%-25% above a national midpoint. Smaller markets with competing fabricators may come in roughly 5%-15% below it, but limited inventory or long delivery distances can erase that difference.
A regional range is a comparison tool, not a substitute for a local slab-based quote. A $125-per-square-foot planning estimate might translate to roughly $140-$155 in an expensive metro, while a straightforward job in a lower-cost market could be closer to $105-$120. Specialty stone may not follow local averages if it has to be shipped from another state.
Ask whether the quote includes transport from the stone yard to the fabrication shop and then to the home. These can be separate charges. Urban parking restrictions, building loading rules, and elevator reservations may add labor or scheduling fees, while a rural address may incur a mileage charge.
What Three Infinity White Installations May Cost
These examples show how scope changes a total; actual slab selection and local rates remain decisive. Each example assumes standard 3-cm stone and ordinary cabinet conditions unless noted.
| Project | Scope and rate | Estimated total |
|---|---|---|
| Compact kitchenette | 18 sq ft at $135 per sq ft, one sink cutout, minimum delivery charge | $2,800-$3,200 |
| Standard kitchen | 40 sq ft at $125 per sq ft, sink and cooktop cutouts, basic edge | $4,900-$5,700 |
| Large kitchen with island | 60 sq ft at $155 per sq ft, upgraded edge, extra handling, old-top removal | $9,500-$11,500 |
The standard kitchen example lands near $5,000 before optional backsplash work or cabinet repairs. A quote can vary even at the same square footage if one job needs two slabs, has more seams, or requires pattern coordination across an island and perimeter counters.
For a fair comparison, provide each estimator with the same rough measurements, sink and cooktop models, desired edge, backsplash height, and access details. Once a fabricator templates the cabinets, the final measured area may differ from the homeowner’s estimate.
How Templating and Stone Installation Affect Labor Charges
Most projects require a site measurement or digital template before fabrication, followed by a separate installation visit. Allow about 1-2 hours for templating and 3-6 hours for a typical installation, though a large kitchen, multiple seams, or difficult access can extend the workday. The countertop may need additional shop time between those visits.
Typical production and scheduling often take 1-3 weeks after slab approval, with installation itself commonly completed in one day. This is not a guaranteed turnaround: special-order stone, a busy shop, cabinet adjustments, or a replacement piece can lengthen the schedule.
Ask whether template, delivery, and installation are included in the quoted total or billed separately. Confirm who disconnects and reconnects plumbing, removes the old countertop, and handles the sink. These tasks may be excluded from a stone contractor’s price and charged by a plumber or demolition crew.
Quartzite Repair and Replacement Compared With New Counters
A small chip or damaged edge may be repairable for about $200-$600, depending on location, color matching, and whether a seam or sink cutout is involved. A crack across a working surface can be more difficult to stabilize, and a visible repair may not disappear completely. A fabricator should inspect the slab before recommending repair.
Repair can cost far less than replacing an entire kitchen, but it is not always a lasting or invisible fix. Replacement for a 40-square-foot installation commonly falls around $3,600-$7,000 before special upgrades, removal complications, or cabinet work. If the original stone is unavailable, matching its color and veining may be difficult.
Sealing and routine care generally cost little compared with the initial installation. Many quartzites benefit from periodic sealing, but frequency depends on the stone and sealer; follow the fabricator’s product-specific instructions rather than applying a fixed annual schedule. Ask whether sealing is included and what care products are appropriate for the selected slab.
All prices are planning ranges in U.S. dollars. Final estimates depend on the actual slab, measured layout, local labor rates, access, and included services.
