Replacing a kitchen sink seems straightforward -- until you discover the drain configuration doesn't match, the countertop cutout needs modification, or the shutoff valves are corroded. Here's what it actually costs.
Labor cost breakdown
Standard sink swap (same hole size, existing shutoffs functional): $200-$350 labor. New cutout or countertop modification needed: add $100-$250. Shutoff valve replacement (common on older homes): $75-$150 per valve. Full installation including new faucet and disposal hookup: $350-$600 labor total.
Sink cost by type
Drop-in (self-rimming): $100-$500 -- easiest to install. Undermount: $150-$800 -- cleaner look, requires solid surface countertop. Farmhouse/apron: $300-$1,500 -- requires cabinet modification. Stainless steel (most common): $100-$400. Cast iron: $300-$900.
Faucet installation
If you're replacing the sink, it usually makes sense to replace the faucet at the same time -- labor overlap keeps the added cost to $75-$150 for installation. Faucets themselves run $75-$500 for quality mid-range options.
What to watch for
Check the shutoff valves under the sink before the plumber arrives. If they haven't been turned in years and look corroded, plan to replace them ($75-$150 each). P-trap and drain assembly replacement is often needed during a sink swap -- add $50-$100 for parts and labor.
Bottom line
Budget $300-$600 total for a standard sink replacement including labor, plus the sink and faucet cost. Older homes with corroded shutoffs should budget on the higher end.
