How much does it cost to install a sink?
Installing a sink typically costs $200–$650 in labor for a like-for-like replacement, plus the sink itself ($100–$800). Undermount sinks, countertop modifications, or plumbing a sink into a new location push the job to $700–$1,500+.

| Scenario | Typical cost | Notes |
|---|---|---|
| Drop-in bathroom sink swap | $200–$400 | Simplest job |
| Kitchen sink replacement | $300–$650 | Disposal & dishwasher lines |
| Undermount install | $400–$800 | Mounting + counter work |
| New location (new plumbing) | $700–$1,500+ | Run supply + drain |
What affects the price
Drop-in vs undermount
A drop-in sink sits in the existing hole and swaps quickly. Undermounts clamp beneath the counter and may need the old adhesive ground off or the cutout adjusted — slower, more careful work.
What connects underneath
A bathroom sink has a drain and two supplies. A kitchen sink adds the disposal, dishwasher drain and maybe a filter — every connection is time, and old corroded shut-off valves often need replacing too.
Same spot or new plumbing
Reusing existing lines keeps it a 1–3 hour job. A sink in a new spot — an island, bar or new vanity wall — needs supply and drain runs, which is the leap to $700+.

How much does it cost to install a sink?
Typically $200–$650 in labor for a replacement — bathroom sinks at the low end, kitchen sinks with disposal and dishwasher connections at the top. The sink itself is extra.
Does sink installation include the faucet?
Usually the plumber will fit a faucet supplied with the sink in the same visit for little or nothing extra. A separate faucet-only install typically runs $150–$350.
Can a handyman install a sink?
A straight swap, often yes. New shut-off valves, moved drains, or disposal wiring are better handled by a licensed plumber so the work is to code and warrantied.
