Cutting a sink hole into a granite countertop is a specialized task where accuracy, tools, and finish quality drive the cost. The price depends on hole size, thickness of the granite, edge profile, and accessibility. The keyword cost is central to budgeting for this custom modification.
Assumptions: standard 2-3 cm granite, single-sink basin, no extensive edge work, normal cabinet access, Midwest labor rates.

Cost To Create A Sink Hole In Granite Countertop
Typical total price often falls in the $250–$1,000 range depending on hole size and granite thickness. Smaller holes around 1.5–2 inches for standard basins tend toward the lower end, while larger, 2.5–3 inch holes or thicker stone push costs higher due to additional core drilling and finishing steps.
How Hole Size And Granite Thickness Drive The Price
Hole diameter and countertop thickness are the two biggest cost levers. Drilling a 2-inch hole in 2 cm granite commonly costs about $250-$450, while a 3-inch hole in 3 cm granite can exceed $600-$1,000. Thicker slabs require longer drill time, more cooling, and careful edge preservation, which adds to labor and tool wear.
Labor Time, Tools, And Skill Level Shaping The Quote
Quote ranges reflect how many hours a fabricator must invest and what tools are needed. Two to five hours at $40–$125 per hour is typical, with rare cases reaching six to eight hours for complex edge profiles. Access to the underside and the basin mounting method also affect both duration and risk of chipping near the cut edge.
Regional Price Variations Within The United States
Prices shift by region due to labor rates and material availability. Urban coastal markets often run higher than rural inland areas, with Midwest projects averaging $350–$650 and West Coast projects commonly $500–$900 for a standard hole.
Different Sink Types And Their Impact On Cost
Basins vary in depth and profile, which changes the cut quality needed. Flush mounting for a shallow double-basin arrangement may stay near the base range, while a deep single-basin cut can add $150–$300 for precise edge finishing and sealing.
Ways To Lower The Price Without Sacrificing Quality
Balancing scope and materials helps manage the cost. Choose a standard circular cut instead of an irregular shape, plan a mid-range edge polish, schedule during non-peak times, and bundle the sink cut with other countertop services to reduce overall labor charges.
Concrete Quote Example: 2-Inch Hole In 2 cm Granite In A Typical Kitchen
The following example illustrates a realistic quote breakdown for a common residential scenario. Hole size: 2 inches; thickness: 2 cm; single sink; standard edge finish; Midwest region.

| Labor | $40 | $70 | $110 | Hour |
| Tools & bits | $40 | $80 | $150 | Job |
| Edge protection & cleanup | $20 | $40 | $75 | Job |
| Delivery/Travel | $0 | $25 | $50 | Job |
| Warranty | $0 | $20 | $60 | Job |
| Estimated total | $250 | $535 | $945 | Job |
Variables That Most Change A Granite Sink Cut Quote
Two key thresholds frequently shift pricing. Hole diameter above 2.5 inches often adds 150–350 more, and thicker slabs over 3 cm can push costs up by 200–400 due to extra cooling and edge work. Site accessibility, existing sink mounting hardware, and required sealing quality also meaningfully alter the final price.
Cost Components In A Formal Quote For A Granite Sink Cut
Understanding the quote anatomy helps compare bids accurately. The four main parts are Materials, Labor, Tools/Equipment, and Finish/Sealing; add a small Contingency if access is tight.

| Labor | $40 | $70 | $125 | Skilled fabricator |
| Tools/Equipment | $40 | $110 | $250 | Core drill, diamonds |
| Finish/Sealing | $20 | $60 | $150 | Polish and water/stone seal |
| Contingency | $0 | $20 | $60 | Unseen edge issues |
