Installed countertops typically cost $50-$120 per sq. ft., depending on whether the surface is granite, quartz, or soapstone. Slab grade, countertop size, edge details, sink cutouts, removal, and local labor rates can shift the final quote substantially.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Granite installed | $50 per sq. ft. | $75 per sq. ft. | $100 per sq. ft. | Natural stone; color and grade affect price |
| Quartz installed | $60 per sq. ft. | $85 per sq. ft. | $110 per sq. ft. | Engineered surface; pattern and brand affect price |
| Soapstone installed | $70 per sq. ft. | $95 per sq. ft. | $120 per sq. ft. | Natural stone; limited colors and slab supply |
| Typical 30-sq.-ft. project | $1,500 | $2,550 | $3,600 | Before unusual demolition or structural work |
Installed prices for a 30-square-foot kitchen
For a standard kitchen with 30 sq. ft. of countertop, granite usually totals $1,500-$3,000, quartz $1,800-$3,300, and soapstone $2,100-$3,600. The averages are about $2,250, $2,550, and $2,850, respectively. These estimates assume midrange material, ordinary access, standard installation, and no major cabinet changes.
Quartz is often the middle-priced option, while soapstone commonly carries the highest material price. A small job may cost more per square foot because fabrication, delivery, and installation have minimum charges. Large islands, premium slabs, and complex layouts can exceed the high end.
Assumptions: 30 sq. ft., typical U.S. labor rates, midrange slabs, standard sink cutout, and normal access.
What granite, quartz, and soapstone quotes include
Quotes differ in how they group materials, fabrication, and removal. Ask whether the listed rate covers measurement, delivery, installation, sink cutouts, and disposal. The following ranges are typical cost components for a 30-sq.-ft. replacement; contractors may bundle them rather than list each charge separately.
| Cost component | Granite | Quartz | Soapstone |
|---|---|---|---|
| Slab material | $900-$1,800 | $1,200-$2,100 | $1,500-$2,400 |
| Fabrication and installation | $450-$900 | $450-$900 | $450-$900 |
| Sink cutout and finished edge | $150-$450 | $150-$450 | $150-$450 |
| Removal and disposal | $150-$450 | $150-$450 | $150-$450 |
Fabrication details can make two quotes for the same stone differ by several hundred dollars. Standard eased edges are generally included or inexpensive; decorative profiles, extra seams, backsplash pieces, and multiple cutouts can add charges. Sink and faucet costs are often separate.
Slab grade, thickness, and cutouts that change the quote
Material selection is only part of the price. Granite and soapstone slabs vary in color, veining, origin, and availability; uncommon patterns can push material rates above typical ranges. Quartz pricing changes with brand, pattern complexity, and slab size. A thicker appearance may use a built-up edge rather than a full-thickness slab.
Layout also matters. A 10-foot run may be less costly to fabricate than the same area split among several short sections with seams. A sink cutout commonly adds $100-$250, while cooktop openings or unusual shapes can add $100-$300 each. Islands wider than 36 inches may need a seam or additional support, depending on slab dimensions and access.
Every extra seam, cutout, or premium slab choice should appear clearly in the written estimate. Confirm whether the quote includes templating and whether the selected slab is reserved for the project.
How installation labor and access affect countertop pricing
Fabricators commonly charge labor through a bundled per-square-foot rate, but labor alone may represent roughly $15-$30 per sq. ft. for measuring, cutting, finishing, and fitting. A straightforward 30-sq.-ft. installation often takes a crew of two several hours after fabrication; measurement and fabrication happen separately and can extend the schedule by one to three weeks.
Stairs, long carries, narrow doorways, parking limits, or cabinet adjustments can add $100-$500 or more. Removing an existing countertop may take extra time, especially when it is glued down or integrated with a backsplash.
Access and preparation are common reasons a low phone estimate changes after an in-home measurement. Provide photos and approximate dimensions when requesting initial quotes, then verify the final price after templating.
Regional differences for stone and engineered counters
Local labor markets and slab distribution affect installed prices. In major coastal cities, quotes may run about 10%-25% above typical national ranges because of labor, delivery, and operating costs. Smaller towns near stone warehouses may be 5%-15% below those ranges, though limited fabricator competition or long delivery distances can erase the savings.
Quartz and granite availability varies by distributor, while soapstone can be harder to source in some areas. Ask whether delivery is priced by distance or included, and compare local quotes for the same material grade and scope rather than comparing headline per-square-foot rates alone.
Regional comparisons are most useful when each quote covers the same removal, edge, cutout, and delivery work.
Three sample countertop quotes for common kitchen layouts
A 25-sq.-ft. granite replacement with a standard edge, one sink cutout, and ordinary removal might total $1,750-$2,500. A 30-sq.-ft. quartz kitchen with a midrange pattern and one cutout might run $2,400-$3,300. A 40-sq.-ft. soapstone layout with an island, premium slab, and extra finishing may reach $3,800-$5,200.
These examples include typical fabrication and installation but exclude new sinks, faucets, plumbing changes, and cabinet repairs. A quote at the upper end may be justified by premium material or difficult access; it should identify those charges rather than use an unexplained surcharge.
Use project-specific totals to compare bids, since countertop area alone does not capture fabrication complexity.
Maintenance differences that affect five-year expense
Granite may need periodic sealing, commonly costing about $30-$100 for a DIY sealer or $100-$300 for professional service. Soapstone does not require sealing, though some owners apply mineral oil for a darker, more even appearance; a bottle often costs $10-$25. Quartz generally needs no sealing, but harsh cleaners and excessive heat can damage the surface.
Routine care is usually a modest expense compared with installation. The practical difference is upkeep preference: soapstone can develop scratches and patina, granite varies by stone and sealant, and quartz offers consistent patterns but can be difficult to repair if chipped or heat-damaged.
Compare maintenance expectations as well as purchase price when estimating the five-year cost.
Where to trim a countertop budget without downgrading blindly
Choose a widely stocked color and standard edge before reducing thickness or selecting a lower grade. Keep the layout simple, reuse a sink if it fits the new cutout, and avoid extra backsplash sections when a separate tile backsplash is already planned. If the existing countertop is easy to remove, ask whether owner-performed removal is allowed and how it affects warranty or liability.
Request at least three written quotes with the same square footage, material selection, edge, cutouts, removal, delivery, and installation scope. Compare slab viewing or reservation terms, deposit requirements, and charges for changes after templating. Combining an island and perimeter counters in one project may reduce minimum fees.
The safest savings come from controlling layout and scope, not accepting an estimate that leaves important work unspecified.
