Estimating the cost to drill holes in granite countertops involves considering hole size, quantity, location, and edge work. The main drivers are the hole diameter, the number of holes, and whether edge polishing or backsplash work is needed. This guide provides practical price ranges in USD to help plan a project budget.
Assumptions: region, hole size, countertop material, and required accessories.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Drilled Hole (per hole, 1-1.5″) | $120 | $250 | $420 | Includes basic cleanup; larger holes cost more |
| Multiple Holes (2-4) | $240 | $520 | $1,200 | Volume discounts may apply |
| Edge Polishing After Drilling | $60 | $150 | $350 | Necessary if drilling affects edge finish |
| Additional Cutouts or Sinks | $100 | $300 | $600 | Varies by complexity |
| Labor & Travel | $50 | $120 | $300 | Per site, may include setup time |
Overview Of Costs
Typical cost range for drilling standard faucet or plumbing holes in granite countertops is roughly $120-$420 per hole, with $250 as a common mid-point. When multiple holes are needed, expect $240-$1,200 for a small project, averaging around $520. If edge polishing or additional cutouts are required, add $60-$350 per item. Labor and travel charges commonly amount to $50-$300 per job, depending on distance and crew availability.
Assumptions: region, specs, labor hours.
Cost Breakdown
The following table outlines how a typical granite-hole project can break down. The figures include a standard 1-1.5 inch hole, with optional edge work and additional cutouts. The per-hole totals assume a single installation in a residential kitchen.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $0 | $0 | $0 | Granite is pre-finished; holes require no extra material beyond warranty considerations |
| Labor | $50 | $120 | $300 | Time for measuring, setup, drilling, and cleanup |
| Equipment | $15 | $30 | $70 | Includes bits, coolant, and dust containment |
| Permits | $0 | $0 | $0 | Typically not required for residential work |
| Delivery/Removal Waste | $5 | $15 | $60 | Depends on site accessibility |
| Warranty | $0 | $20 | $50 | Limited coverage for edge chipping |
| Contingency | $0 | $15 | $40 | Contaminants or misalignment risk |

What Drives Price
Hole size and quantity are primary cost determinants. A larger diameter or more holes increases drill time and potential edge work. The edge finish after drilling adds cost if the hole creates a visible edge bevel or crack risk. Additionally, the countertop thickness and the presence of a sink or backsplash can influence manpower and tooling needs.
Tooling and technique matter: diamond-tipped bits and coolant reduce edge damage and produce cleaner holes but add to equipment costs. A shop with CNC or high-precision portable drills may complete a job faster but charge more for premium service.
Regional Price Differences
Prices vary by market, with urban areas typically higher than suburban or rural locations due to labor rates and accessibility. In the three example markets, expect ranges as follows:
- Coast/Metropolitan: +5% to +15% vs national averages
- Midwest Suburban: near national averages
- Rural/Southern: -5% to -15% vs national averages
Regional delta notes reflect travel time, installer demand, and material availability, not quality. A local pro may offer bundled services (drilling with sink installation) at a discount.
Labor, Hours & Rates
Most projects are completed in 1–3 hours per site, depending on hole count and complexity. The typical hourly rate ranges from $60 to $150. If multiple holes must be rounded or if there is heavy edge polishing, a full-day rate may apply.
Assumptions: region, specs, labor hours.
Real-World Pricing Examples
Three scenario cards illustrate common project scales. Each includes basic specs, estimated hours, per-unit costs, and totals. Parts lists vary to show how choices influence price.
Basic: 1 hole, 1.25″ diameter, standard edge
Specs: standard kitchen island, single faucet hole; no sink cutouts. Hours: 1.0–1.5. Per-hole price: $120-$180. Total: $120-$180 plus minor cleanup.
Mid-Range: 3 holes, 1.5″ diameter, modest edge work
Specs: 3 faucet holes; minor edge chamfer after drilling; basic dust containment. Hours: 2–3. Per-hole price: $210-$320. Total: $630-$960.
Premium: 4 holes, 2″ diameter, heavy edge restoration
Specs: 4 faucet holes; edge polish return; additional cutouts for adapters; on-site measurement. Hours: 3–4. Per-hole price: $290-$420. Total: $1,160-$1,680.
Assumptions: region, specs, labor hours.
Cost By Region
To help with budgeting, a quick regional snapshot shows different cost envelopes for granite-hole work. The ranges below assume standard 1-1.5″ holes and one installer.
- Urban Northeast: $140-$480 per hole; average around $260
- Midwestern Suburbs: $120-$360 per hole; average around $210
- Rural Southwest: $110-$350 per hole; average around $180
Surprise fees can appear if a hidden edge crack is discovered or if a special drill bit is required. Ask for a written estimate that lists hole diameter, total holes, edge work, and travel charges.
