Installing a new kitchen sink typically costs $300-$1,200, with an average near $700 when the replacement fits the existing countertop and plumbing. Sink material, countertop modifications, faucet or drain work, and local labor rates can raise the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed sink replacement | $300 | $700 | $1,200 | Sink and standard installation; faucet may be extra |
| Sink unit | $100 | $350 | $1,000+ | Stainless steel to premium fireclay or stone |
| Installation labor | $200 | $350 | $650 | More for plumbing or countertop changes |
| Countertop modification | $0 | $250 | $800+ | Usually unnecessary for a matching replacement |
New Kitchen Sink Installation Prices by Sink Type
A basic drop-in stainless-steel sink replacement generally totals $300-$700, including a $100-$300 sink and routine labor. An undermount model often costs $500-$1,200 installed because it needs secure mounting and careful sealing. Higher-end fireclay, granite composite, or copper sinks can push the total to $1,500-$3,000 or more, especially if the counter or cabinet needs adjustment.
For a like-for-like replacement with sound plumbing, budgeting $500-$900 covers many standard projects. These estimates generally exclude a new faucet, major drain relocation, and countertop replacement. Assumptions: U.S. midrange labor rates, standard-size sink, accessible shutoff valves, and no major repairs.
What Goes Into a Sink Installation Quote
Ask for an itemized quote that separates the sink, installation, and any plumbing or counter work. The ranges below are typical for a straightforward replacement; labor and add-ons vary by location and access.
| Quote item | Typical price | What it covers | When it rises |
|---|---|---|---|
| Sink | $100-$600 | Standard stainless or composite unit | Large, heavy, or premium material |
| Labor | $200-$500 | Removal, setting, connection, sealing | Undermount work or difficult access |
| Plumbing parts | $25-$150 | Strainer, clips, tailpiece, supply lines | Worn valves or incompatible drain |
| Removal and disposal | $30-$150 | Taking away the old sink | Heavy material or separate disposal fee |
| Countertop work | $0-$800+ | Cutout adjustment or edge finishing | New size or material-sensitive surface |
Labor is usually the largest installation charge when the sink opening and plumbing already match. A simple labor estimate may use Typical plumber or installer rates are about $75-$150 per hour, with minimum service charges sometimes applying.
How Cabinet Size and Plumbing Changes Shift the Price
Sink dimensions and cabinet clearance matter: a 30-inch sink base can limit the bowl width, while a larger basin may require cabinet alterations. Moving a drain or supply connection several inches can add roughly $150-$500; rerouting pipes through a wall or cabinet may cost $500-$1,500 or more.
Countertop material also affects the quote. A modest cutout adjustment in laminate may cost $100-$300, while stone or quartz work can run $300-$800 or more and may require a countertop specialist. Replacing a drop-in sink with an undermount model can involve extra support and finishing.
Confirm the sink’s outer dimensions, cutout size, and cabinet width before ordering. That check helps prevent return fees and avoids paying for an unexpected counter alteration.
Lower the Sink Bill by Keeping the Existing Cutout
Choosing a sink with the same installation style and a compatible cutout is often the most direct way to control the price. Reusing functional faucet, disposal, and supply connections can also reduce parts and labor, though worn or leaking components should be replaced rather than concealed.
Compare at least two itemized quotes with the same sink model and scope. Check whether removal, disposal, new drain parts, and leak testing are included. Buying the sink yourself may save money, but confirm the installer accepts customer-supplied fixtures and ask how defects or missing hardware affect labor charges.
Avoid paying for countertop or plumbing changes unless measurements or the existing condition require them. Keeping the job to a standard replacement can preserve the lower end of the price range.
How Long Does a Kitchen Sink Replacement Take
A straightforward swap usually takes 2-4 hours for one installer, including disconnecting the old unit, setting the replacement, reconnecting the drain, and checking for leaks. A plumber may charge a minimum visit fee of $100-$250 even when the hands-on work is brief.
Undermount installation, corroded fittings, a stuck disposal, or a damaged cabinet can extend the job to 4-8 hours or require a return visit. If countertop cutting is needed, scheduling a separate fabricator can add several days to the project timeline.
Have the new sink on site and the cabinet cleared before the appointment to reduce paid labor time.
Extra Charges for Countertop Cuts and Old Sink Removal
Old sink removal and disposal may add $30-$150, with heavier cast-iron or stone units costing more to handle. A new strainer or drain assembly can add $25-$100, while replacing shutoff valves may add about $100-$300 depending on access and plumbing condition.
Countertop cutting is a separate specialty charge, not always included in a plumber’s quote. Expect about $100-$300 for straightforward laminate adjustments and $300-$800 or more for stone work. If the new sink needs a larger opening, verify that the counter material can be cut safely before purchase.
Get approval for any added work before the installer proceeds. A quote that lists likely contingencies makes the final bill easier to compare.
Three Kitchen Sink Quotes With Different Scopes
A basic example is a 25-inch drop-in stainless sink, existing cutout, and reusable faucet: a $180 sink, $280 labor, and $60 in drain parts total about $520. The installer spends roughly 3 hours on site, with no countertop work.
A midrange example is a 30-inch composite sink with a new strainer and disposal connection: a $450 sink, $400 labor, and $120 parts and removal total about $970. The job may take 4-5 hours if fittings need replacement.
A higher-scope example is a 33-inch undermount fireclay sink requiring stone-cutout adjustment: a $900 sink, $600 installation, $500 counter work, and $150 parts or disposal total about $2,150. The counter work may be billed separately.
These examples show why sink price alone is not a reliable estimate of the installed total. Local rates, taxes, and site conditions can change each figure.
Repairing the Existing Sink Versus Replacing It
A new strainer, seal, or faucet connection may resolve a localized leak for $100-$350, depending on access and parts. Repair is less attractive when the basin is cracked, badly corroded, or repeatedly leaking around its rim, especially if labor to remove it is already needed.
Replacement makes more financial sense when the sink is near the end of its useful life or the cabinet and counter are being updated at the same time. Before deciding, compare the repair quote with the installed price of a standard sink and include any disposal or plumbing charges in the comparison.
For a sound sink with a single failed fitting, repair can cost substantially less than full replacement.
