The cost to cut granite for a sink typically ranges from $150 to $600 for a straightforward opening, with an average near $350. Price depends on whether the slab is already installed, sink dimensions and shape, granite thickness, access, and whether polishing or plumbing disconnection is included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Shop-cut opening in loose granite | $150 | $300 | $500 | Standard sink shape; countertop is accessible |
| Cut existing installed granite | $250 | $450 | $850 | On-site work with dust protection and access limits |
| Sink cutout rate | $8/sq. ft. | $18/sq. ft. | $35/sq. ft. | May be subject to a minimum service charge |
| Polishing exposed cut edge | $10/linear ft. | $25/linear ft. | $45/linear ft. | Depends on edge finish and stone condition |
What Does It Cost to Cut a Granite Sink Opening?
A basic sink opening cut into a loose granite countertop usually costs $150-$500. On an installed counter, expect roughly $250-$850 because the fabricator must protect cabinets and nearby surfaces, control dust, and work around walls or plumbing. The average straightforward installed job is about $350-$450.
These prices assume one standard kitchen sink opening, ordinary access, and granite in sound condition. A small bathroom vanity opening may cost $125-$350, while a large farmhouse or custom-shaped opening can reach $500-$1,000 before plumbing or sink installation. Contractors commonly set a minimum charge of $150-$300 even when the cut is small.
For budgeting, use $350-$450 for a standard on-site sink cut and add extra for edge finishing or removal. Per-square-foot rates can help compare quotes, but most shops price sink openings as a job because setup, measuring, and tool time are significant even for a modest cutout.
Assumptions: Standard 1.25-inch granite, one sink opening, typical U.S. metro-area labor, no major repairs or plumbing changes.
Which Shop Charges Appear on a Granite Cutting Quote?
A quote may combine cutting labor, polishing, travel, and protection rather than listing a single cutting fee. Ask whether the price covers only the opening or also includes removing the old sink, hauling debris, making the cutout usable, and fitting the new sink. A written scope helps prevent a low initial quote from growing after work begins.
| Quote item | Typical price | What it covers | Common cost trigger |
|---|---|---|---|
| Cutting labor | $150-$450 per opening | Layout, cutting, and handling | Installed counter or difficult access |
| Edge polishing | $10-$45 per linear ft. | Smoothing and finishing exposed stone | Visible edge or premium finish |
| Equipment and site protection | $25-$125 per job | Blade wear, dust control, floor and cabinet protection | Indoor wet-cut setup or sensitive finishes |
| Sink removal and disposal | $40-$150 | Disconnecting or handling the existing sink and debris | Heavy cast-iron sink or difficult removal |
| Travel or minimum charge | $75-$250 | Service call, transport, and shop setup | Rural location or small one-off job |
Labor is often the largest portion of a one-opening quote. If a contractor bills time and materials, a common labor range is $75-$150 per hour, with setup and cleanup adding time beyond the actual cutting.
Confirm whether polishing and site protection are included before comparing total quotes. Some fabricators include edge finishing in the cut price, while others charge per linear foot. Tax and plumbing work may also be separate.
How Slab Thickness, Sink Size, and Edge Shape Change Price
Standard 1.25-inch granite is the least complicated to cut. A 2-inch slab, laminated edge, or reinforced section can require slower cutting and additional finishing, commonly adding $50-$200. Granite with existing cracks, weak support, or a narrow strip between the opening and countertop edge may need reinforcement or a different layout.
Opening size affects both cutting time and the risk of breakage. A typical top-mount or undermount kitchen sink requires an opening roughly 18-22 inches wide and 28-34 inches long, though exact dimensions vary by sink. A larger farmhouse sink opening around 30-36 inches wide can add $75-$250 compared with a standard cut, especially when it removes more material near the counter’s front edge.
Shape matters as well. A rectangular opening with rounded inside corners is typically less expensive than a custom radius, unusual oval, or multiple-bowl layout. Custom templates or precise undermount sizing may add $50-$200. A tight corner radius can reduce the chance of stress cracks, but the dimensions must match the sink manufacturer’s template.
Measure the actual sink template, not just the sink’s outside dimensions. A mismatch of even 1/4 inch can leave inadequate support, expose a rough edge, or prevent the sink from fitting. The fabricator may charge $40-$125 to create or verify a template if one is not supplied.
Access is another price driver. A counter that can be removed and transported to a shop may cost less to cut than one fixed between walls or joined to adjacent slabs. On-site work above a finished cabinet, near a backsplash, or in a small kitchen can add $75-$250 for protection and careful handling.
How Can Homeowners Lower the Granite Sink-Cut Price?
Keep the work limited to one accurately specified opening. Provide the sink model, manufacturer’s cutout template, slab thickness, and clear photos of the counter. Confirm whether the sink is top-mount or undermount and identify any existing faucet holes or seams. Better information can reduce a paid measuring visit and limit errors that require a second trip.
Ask a countertop fabricator whether the granite can be cut at the shop. If the counter is already installed, removal may cost more than on-site cutting, but a loose remnant or newly fabricated slab may be easier and less expensive to process in a controlled workspace. Avoid arranging removal until the fabricator confirms the slab can be handled without damage.
Compare at least three written quotes with the same scope. Include the cut, edge finish, travel, cleanup, and any sink removal in each request. A $225 quote that excludes polishing and service travel may cost more than a $375 all-in quote. Ask whether the business has a minimum charge and whether pricing changes if the opening needs adjustment.
Choose the simplest sink shape and edge treatment that fit the kitchen plan. A standard rectangular opening can avoid custom layout charges, and an unfinished cut edge hidden beneath an undermount sink may not need decorative polishing. Do not skip finishing required for a safe, stable fit or exposed edges.
Scheduling the cut with other countertop work may reduce separate mobilization fees. If replacing the sink, verify the new sink’s exact dimensions before the granite is altered; buying the sink after cutting can lead to additional grinding or a costly mismatch.
Does Cutting Installed Granite Cost More Than Shop Fabrication?
Shop fabrication is usually less expensive when the granite is already loose, accessible, and safe to transport. A shop can use a cutting table, water-fed saw, and controlled supports. A standard shop cut may run $150-$500, while cutting an installed countertop often falls around $250-$850 because the crew must work in the home and protect finished surfaces.
On-site cutting is often practical when the slab is bonded to cabinets, joined to other countertop sections, or too large to move safely. It can also avoid the risk of cracking the granite during removal and transport. However, indoor work needs careful dust and water management, and the fabricator may not be able to make every cut as cleanly as a shop setup.
Removal and transport can add $100-$400 or more, depending on the slab, distance, and whether the counter must be separated at seams. A long or heavy section may require additional crew members. If removing it risks damage to the granite, backsplash, or cabinets, the apparent shop savings may not justify the extra handling.
Compare the full installed-work price with the cut, removal, transport, and reinstallation total. Get the fabricator’s assessment before choosing a method; not every slab can be removed intact, and some shops will not accept customer-supplied granite with unknown condition.
How Long Does a Granite Sink Cut Take, and What Labor Is Billed?
A simple shop cut may take 1-3 hours of active fabrication time, although scheduling, curing any repairs, and shop workload can extend the turnaround to several days. On-site cutting often takes 2-5 hours for one opening, including measuring, masking, cutting, polishing, and cleanup. Difficult access or extra finishing can extend the visit to most of a workday.
One experienced fabricator may handle a straightforward cut, but two workers may be needed to stabilize a large slab or protect the countertop during handling. Typical billed labor of $75-$150 per hour means a two-person crew can make labor alone $150-$300 per hour before travel, consumables, and business overhead. Some companies quote a flat rate instead of an hourly amount.
Ask whether the appointment includes a site visit, template check, and cleanup. A measurement visit may cost $50-$150, sometimes credited toward the job. Same-day or urgent service can add $75-$250 when a crew must be rescheduled or dispatched outside its normal route.
Price the entire visit rather than multiplying cutting time by an hourly rate. Setup, protection, measuring, and cleanup are real labor even when the blade is in use for only part of the appointment.
What Extras Raise the Bill Beyond the Sink Cut?
Changing the sink type can create work beyond cutting. Switching from a top-mount sink to an undermount model may require a finished stone edge, clips or supports, and a precise opening. Edge polishing commonly costs $10-$45 per linear foot, while mounting hardware and support work may add $50-$250 depending on the setup.
Plumbing is usually a separate trade. Disconnecting and reconnecting a basic sink may cost $150-$400, excluding new faucets, drains, or supply lines. Repositioning pipes or correcting old plumbing can raise that amount. If the sink is heavy cast iron, removal and disposal may cost $75-$200, particularly when a second worker is needed.
Repairs and unusual site conditions can also change a quote. Filling a small chip or stabilizing a minor crack may cost $100-$350, but a crack crossing the proposed opening may make the cut unsafe. Cutting around a backsplash, narrow cabinet rails, or an existing seam may add $75-$250 or require a redesigned opening.
Separate stone fabrication, sink installation, and plumbing charges in the estimate. This makes it clear which contractor is responsible if the sink does not fit or if the opening needs further adjustment.
When Is Recutting Granite Cheaper Than Replacing the Countertop?
Recutting is usually worth pricing when the existing granite is intact, the new sink fits within the available counter area, and the cutout will not weaken a narrow section. A straightforward adjustment may cost $250-$600, compared with roughly $1,500-$4,500 for replacing a typical 30-50-square-foot granite countertop with basic fabrication and installation. Larger kitchens, premium stone, and backsplash work can exceed that range.
Replacement may make more sense if the stone has a crack near the opening, the new sink is substantially larger, or the current counter has insufficient support. A fabricator should check the distance between the opening and the front edge, cabinet rails, seams, and nearby corners. There is no universally safe clearance for every slab; stone type, thickness, reinforcement, and cut shape all matter.
A sink with a smaller cutout can sometimes be installed using an adapter or a different mounting style, but those options depend on the sink and counter design. A top-mount sink may cover an older opening if its rim is wide enough, while an undermount sink generally requires an accurate, finished edge. Confirm fit with the sink manufacturer’s dimensions before paying for alterations.
Request both a recut estimate and a replacement estimate when the opening is large or the slab is compromised. Compare total costs, including removal, disposal, plumbing, new fabrication, and installation—not just the price of the granite itself.
