Understanding the cost of engineered quartz versus granite helps buyers budget for kitchen renovations. The cost hinges on material choice, fabrication, edge profiles, and region-specific labor. This article outlines typical price ranges and the main drivers behind the cost of quartz and granite countertops.

Assumptions: standard 3cm slabs, 25-30 square feet typical kitchen, mid-range edge profiles, and standard knife-safe finishing; regional labor varies by market.

Item	Low	Average	High	Notes
Installed quartz price per sq ft	$55	$85	$120	Includes fabrication and installation
Installed granite price per sq ft	$40	$70	$100	Includes sealing and basic edge
Total project for 25 sq ft quartz	$1,375	$2,125	$3,000	Assumes standard edge
Total project for 25 sq ft granite	$1,000	$1,750	$2,500	Assumes standard edge

Quartz Countertop Installed Price Per Square Foot and Range

Engineered quartz costs generally range from $55 to $120 per square foot installed. The lower end reflects standard slabs with simple edges and local labor, while the higher end captures premium patterns, colorways, and complex profiles. Labor and fabrication time scale with the number of cutouts, sink mounts, and edge types. For a typical 25–30 sq ft kitchen, a quartz project often lands around $1,400 to $2,600 before any allowances for demolition or cabinets.

Assumptions: mid-range edge, standard seams, typical under-mount sink, no heavy erosion or specialty finishes.

Granite Countertop Installed Price Per Square Foot and Range

Granite installed costs typically run from $40 to $100 per square foot. Price variations come from slab quality, color, country of origin, and the complexity of fabrication. A standard 25 sq ft granite project commonly totals about $1,000 to $2,500, with higher-end slabs and multiple sink cutouts pushing toward the upper end.

Assumptions: 3cm thickness, basic eased edge, standard sealing, and reliable local fabricator.

Major Quote Components: Materials, Labor, and Fabrication

When comparing quotes for quartz or granite, a clear breakdown helps estimate final cost. Typical components include materials, labor, edge finishing, and installation labor. The following table shows common line items and how they usually price out.

Component	Typical Cost	Notes	Per-Unit/Per-Job
Materials	$40–$100+ per sq ft	Quartz or granite slab cost by material grade	per sq ft
Fabrication/Labor	$15–$40 per sq ft	Cutouts, polishing, edge work	per sq ft
Edges	$5–$40 per linear ft	Straight, ease, bullnose, ogee	per linear ft
Sealing/Prep	$0–$8 per sq ft	Granite sealing; quartz typically no seal	per sq ft
Delivery/Installation	$0–$25 per sq ft	Haul and install, scaffolding if needed	per sq ft
Waste/Disposal	$50–$200	Old countertop demolition and disposal	flat fee

Formula: labor hours × hourly rate + material cost + edge cost + seaming.

Size and Edge Detail Impact on Engineered Quartz Cost

Edge profiles and kitchen size materially shift price. A standard 25 sq ft layout with a simple edge (square or eased) is at the low end, while a 40–50 sq ft layout or an intricate edge (bullnose, bevel, princess) adds material and fabrication time. Larger islands or multiple corners increase waste and setup time, pushing per-square-foot costs higher even if slab price remains consistent.

Assumptions: single island, mixed cabinet layout, no unusual miters.

Slab Availability and Regional Sourcing Affect Prices

Regional differences in slab availability influence costs. Regions with abundant local quarry options may see lower granite prices, while premium quartz brands with limited distribution can raise costs. Import duties, freight, and lead times also affect final quotes, particularly for exotic colors or patterns. In practice, expect more price pressure for high-contrast or highly purchased colors in tight markets.

Assumptions: standard distribution, no rush delivery, normal lead times.

Maintenance Costs and Longevity Compared

Long-term maintenance affects the total cost of ownership for both materials. Granite requires periodic sealing to maintain stain resistance, generally every 1–3 years depending on usage, adding a recurring cost of $0.50–$1.50 per sq ft annually if done professionally. Engineered quartz resists stains and does not require sealing, potentially reducing ongoing expenses but sometimes needing light resealing if damaged. Longevity differences are often reflected in warranty terms and replacement cycles rather than annual costs alone.

Assumptions: typical residential kitchen use, standard care, normal wear patterns.

Replacement versus Repair: When to Reconsider Quartz or Granite

Cost decisions hinge on replacement cycles and repairability. If a countertop sustains deep damage or stains not amenable to resealing, replacement costs for quartz or granite can run from $1,000 to $4,000 depending on size and edge choices. Minor repairs or seam resealing usually stay well under $500. Quartz often fares better with chip repair options that avoid entire slab replacement, while granite repairs depend on slab color and availability of matching slabs for seamless blends.

Assumptions: mid-range repair scope, standard kitchen footprint, no structural upgrades.

Regional Price Deltas and Market Variations

Expect regional adjustments of 5% to 20% by market. Coastal metros with higher labor costs and showroom competition may push quotes higher, while rural areas with fewer suppliers can show tighter margins but longer lead times. A quartz project in a high-demand market might sit at the upper end of the installed range, whereas granite could be lower in regions with plentiful local quarries.

Assumptions: typical regional pricing bands, no rush fees.
