Dekton countertops typically cost $60-$120 per square foot installed, while granite usually costs $40-$100 per square foot. For a 30-square-foot kitchen, that puts many projects between $1,200 and $3,600 for granite or $1,800 and $3,600 for Dekton, with slab selection, edge work, access, and installation complexity driving the final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Dekton installed | $60/sq ft | $90/sq ft | $150/sq ft | Premium designs or complex fabrication can exceed the high range |
| Granite installed | $40/sq ft | $70/sq ft | $120/sq ft | Color, grade, thickness, and edge profile affect price |
| 30-sq-ft Dekton project | $1,800 | $2,700 | $4,500 | Typical countertop area, excluding unusual structural work |
| 30-sq-ft granite project | $1,200 | $2,100 | $3,600 | Includes standard fabrication and installation |
What Dekton and granite countertops cost installed
Dekton commonly lands at $60-$120 per square foot installed, or roughly $1,800-$3,600 for 30 square feet. Higher-end colors, large-format slabs, waterfall panels, and detailed seams can push a project to $150 per square foot or more. The material is a sintered surface made under high heat and pressure, and its fabrication requires specialized tools and experienced installers.
Granite often costs $40-$100 per square foot installed, making a 30-square-foot job about $1,200-$3,000. Common colors and basic profiles may fall near the low end; rare colors, premium slabs, thicker edges, or extensive vein matching can approach or exceed $120 per square foot. Granite is natural stone, so slab variation and selection have a meaningful effect on the estimate.
For a like-for-like kitchen, granite is often less expensive, but premium granite and midrange Dekton prices can overlap. These ranges assume standard countertop thickness, ordinary access, a typical kitchen layout, and basic sink and cooktop cutouts. Assumptions: U.S. installed pricing, 25-40 square feet, standard edge, normal access, and no major cabinet or plumbing changes.
How slab, fabrication, and labor shape each quote
A countertop quote includes more than the visible surface. Ask whether it covers measuring, templates, cutouts, seams, delivery, removal, installation, and taxes; exclusions can make two apparently similar bids difficult to compare. The following ranges are common planning allowances, not fixed line items, because fabricators bundle work differently.
| Cost component | Dekton range | Granite range | What changes the charge | Typical unit |
|---|---|---|---|---|
| Material | $35-$90 | $20-$70 | Color, grade, thickness, slab yield | Per sq ft |
| Fabrication and labor | $20-$45 | $15-$35 | Cutouts, edge shape, seams, handling | Per sq ft or project |
| Equipment and delivery | $100-$500 | $100-$450 | Crane, stairs, distance, slab size | Per job |
| Removal and disposal | $200-$700 | $200-$700 | Old top material and disposal access | Per job |
| Overhead and contingency | $150-$600 | $100-$500 | Scheduling, breakage risk, difficult site | Per job |
Material prices in this table are not necessarily amounts that can be added directly to the installed rate. Some contractors quote one square-foot figure that already includes fabrication and installation; others list separate charges. Compare the written scope and total installed price, not only the slab price per square foot.
Labor is commonly priced as part of a fabrication and installation package. For a separate labor estimate, a small crew may spend 8-16 hours measuring, moving, fitting, and finishing a standard kitchen, with rates around $50-$100 per worker-hour depending on market and trade.
Thickness, cutouts, and slab layout change the price
Slab thickness, design, and layout affect both material use and fabrication time. Standard countertop thickness is often around 2 cm or 3 cm, though the product and market determine availability. A 3-cm top or a built-up edge may cost more than a standard 2-cm choice, especially when the design calls for a thick-looking edge on every exposed side.
For Dekton, large or continuous-looking surfaces may require careful panel planning, and some installations use a thinner surface bonded to a support. Large panels are difficult to transport and handle without damage. Granite slab yield also matters: an unusual color or a layout that must match veins may require buying more material than the measured countertop area suggests.
Cutouts and edge details add labor. A sink or cooktop opening may add roughly $150-$500 each, depending on shape, finish, and whether the cutout is made at the shop or on site. A simple eased edge is commonly included, while decorative profiles may add about $10-$30 per linear foot. Waterfall sides often add $800-$2,500 or more per side after material, mitering, and installation are considered.
Measure the full run and count finished edges before comparing bids. A 25-square-foot straight counter with one sink opening is not equivalent to a 25-square-foot kitchen with an island, several cutouts, exposed ends, and a waterfall panel.
Regional labor rates from city kitchens to rural homes
Labor and delivery can shift the installed price by roughly 10%-25% between lower-cost and high-cost U.S. markets. Major metro areas, including parts of the Northeast, California, and the Pacific Northwest, may quote above national midrange due to labor, shop, insurance, and transportation expenses. Smaller markets may offer lower labor rates but have fewer fabricators equipped to handle Dekton.
Urban access can add costs when crews must reserve elevators, carry panels through narrow stairwells, or park far from the home. Rural projects may face mileage or delivery surcharges, particularly when the slab comes from a distant supplier. A crane or specialized lift can add approximately $300-$1,500 when panels cannot safely pass through the building.
Ask whether a quote includes travel, delivery, and site access charges, and whether the installer has handled the selected material before. Local availability matters as much as the national per-square-foot range, especially for Dekton fabrication. Obtain at least two local bids with matching measurements and work descriptions.
Three kitchen quotes show the price difference
These examples illustrate plausible installed totals rather than guaranteed market prices. Each assumes standard cabinets in usable condition, ordinary access, a basic edge, and no plumbing relocation. Actual slab selection and local labor can move the quote substantially.
| Project | Material and area | Added scope | Estimated total | Approximate rate |
|---|---|---|---|---|
| Small rental kitchen | Granite, 24 sq ft | One sink cutout, removal, basic edge | $1,500-$2,400 | $63-$100/sq ft |
| Midrange family kitchen | Dekton, 35 sq ft | Sink and cooktop cutouts, standard seams | $2,800-$4,500 | $80-$129/sq ft |
| Large island kitchen | Premium granite, 50 sq ft | Two cutouts, upgraded edges, island handling | $4,500-$7,500 | $90-$150/sq ft |
The rental kitchen could cost less with a common granite color and an uncomplicated removal. The Dekton kitchen has more area and two cutouts, so its total is not a direct material-only comparison. The island example carries a premium because large pieces may need more slab material, careful transport, and extra support or handling.
Normalize each quote to the same square footage, cutouts, edge, removal, and delivery scope. If one bid includes a sink cutout and disposal while another excludes them, its headline rate can be misleading.
Repair, resealing, and long-term upkeep differ
Dekton is nonporous and generally does not require routine sealing. Granite is also durable, but many granite tops benefit from periodic sealing; frequency depends on the stone and the sealer, and a professional application may cost about $150-$400. Homeowners can often apply an appropriate sealer themselves for roughly $20-$60 in supplies.
Neither surface is immune to damage. Granite can chip at an edge or crack under impact, while Dekton can chip if a hard object strikes an exposed edge. Local repairs may run approximately $200-$600 for a small chip or minor repair, with larger cracks or replacements costing more. Repair success depends on location, color match, and the nature of the damage.
Over five years, routine granite sealing may add around $20-$400 depending on DIY versus professional service, while Dekton usually has little routine surface-maintenance expense. That comparison excludes cleaning products, accidental damage, and warranty terms. Low maintenance can narrow ownership-cost differences, but it does not guarantee a lower initial Dekton price.
Cut add-ons without sacrificing the countertop plan
Keeping the layout simple is one of the most reliable ways to control cost. Retaining the sink and cooktop locations avoids extra cutouts and may prevent plumbing or electrical work. A straight edge, fewer seams, and no waterfall sides reduce fabrication complexity. Choosing a common granite color can also lower material cost compared with a rare or heavily patterned slab.
For Dekton, ask the fabricator which colors and thicknesses are stocked locally and whether the selected panel can be nested efficiently. Confirm the finished dimensions before ordering, since a layout change after fabrication can waste expensive material. For granite, inspect the actual slab when appearance matters; selecting a suitable remnant for a small vanity or laundry counter may cost less than ordering a full slab, if the dimensions work.
Removal, disposal, and site preparation can sometimes be handled separately, but only when the contractor approves the plan and the cabinets are protected. Removing an old countertop without damaging the cabinets may save a few hundred dollars; a mistake can cost more to repair. Prioritize scope and layout savings before choosing a weaker support system or skipping required installation steps.
Delivery, removal, and edge charges to confirm
Quotes may exclude old-countertop removal, sink disconnects, plumbing reconnection, backsplash work, or cabinet leveling. Removal and disposal commonly add $200-$700 for a typical kitchen, while reconnecting plumbing may add $150-$500 depending on fixtures and local rates. New backsplash tile or wall repair is usually a separate project and can add several hundred dollars or more.
Check whether the quote includes templating, delivery, seam placement, sink support, and final cleanup. A heavy slab may require cabinet reinforcement, particularly around a wide span or overhang; reinforcement can add about $100-$600, depending on the fix. A large overhang may also need brackets or other approved support rather than relying on the countertop alone.
Confirm warranty coverage in writing for both the material and workmanship. Manufacturer coverage and installer coverage are different, and exclusions may include impact damage, improper support, or unauthorized repairs. A detailed quote should name every included cutout, finished edge, seam, delivery fee, removal charge, and follow-up service.
