Homeowners typically pay a broad range when converting a double kitchen sink to a single unit. The main cost drivers are cabinet modifications, plumbing rework, fixture choices, and disposal of old components. This article breaks down the price, with practical low–average–high ranges, to help-budget decisions.

| Double-to-Single Sink Mod | $200 | $600 | $1,800 | Cabinet cut, sink cutout, and re-seating. |
| Faucet & Fixture Changes | $80 | $250 | $700 | Single-handle or pull-down options add cost. |
| Plumbing Rework | $150 | $420 | $1,200 | Drain, trap, and supply lines adjustments. |
| Permits & Inspections | $0 | $50 | $200 | Typically not needed in a basic remodel. |
| Delivery/Disposal | $20 | $60 | $150 | Old fixtures and materials disposal. |
| Waste/Overage & Contingency | $0 | $80 | $300 | Unforeseen cuts or misfits. |
Overview Of Costs
Typical project ranges reflect a simple cut-and-seal plus basic fixtures versus a full rework with premium hardware. For assumptions: region, standard 30–40-inch cabinet base, and access from underneath. Assumptions: region, specs, labor hours.

What Drives Price
Cabinet modification complexity is a major driver, because removing a divider or adjusting the countertop may require a precise cut and re-seating. Plumbing configuration matters: a rare drain layout or long trap run increases labor hours and material use. Material choice for the new sink and faucet also shifts the total, especially when opting for heavy-duty stainless or specialty finishes. Regional labor rates and existing access under the sink further influence price.
Labor, Hours & Rates
The project commonly takes 1–2 days for a typical kitchen with accessible plumbing. Expect 2–6 labor hours for a straightforward conversion, plus 1–2 hours for cleanup and test runs. data-formula=”labor_hours × hourly_rate”> In markets with high living costs, labor can be 15–25% above national averages. Scheduling during off-peak hours can reduce labor fees in some markets.
Regional Price Differences
Prices vary by region due to labor markets and material costs. In the Northeast, expect higher labor charges; the Midwest offers more balanced pricing; the West can show premium fixture options. Urban areas typically run 10–25% higher than Rural locations, while Suburban markets sit between these ranges.
Labor & Installation Time
Time spent includes cabinet adjustments, countertop work, and aligning the new basin. If a disposer line or garbage disposal is tied into the sink, extra work may be needed. Time estimates should include testing for leaks and ensuring counter support remains solid. A compact remodel reduces downtime but can still require temporary kitchen adjustments.
Additional & Hidden Costs
Hidden costs may include extra hardware, trim pieces, or sealant upgrades to prevent water damage. Old sink removal and disposal fees are sometimes overlooked. If the existing plumbing uses nonstandard pipe sizes, adapters and additional fittings add cost.
Cost Compared To Alternatives
Compared with installing a single, larger sink unit, the change can be cheaper than replacing the entire cabinet and countertop. Alternative options include reusing one basin with a wider divider or narrowing the cabinet opening for a single-bowl sink. If a full-scale kitchen remodel is already planned, combining tasks may save on permits and labor time.
