The kitchen sink is one of the most-used fixtures in any home, so homeowners want the installation done right and priced fairly. At CountBricks, we combine certified residential craftsmen with AI-driven estimating to give you crystal-clear numbers before demolition begins. This guide breaks down every factor that shapes kitchen sink installation cost and shows how CountBricks keeps budgets on track.
Kitchen sink installation cost is never one-size-fits-all. CountBricks estimators see four primary variables on most residential jobs:
• Sink type and material – stainless drop-in, fireclay apron, composite undermount, or an integrated work-station all carry different price tags
• Plumbing complexity – replacing supply lines only is quick; relocating the drain line or adding a garbage disposal increases labor
• Countertop modifications – cutting a new hole in granite, quartz or butcher block requires different tooling and time
• Local labor rates – CountBricks pulls up-to-the-minute data for your ZIP code, so a Los Angeles project reflects L.A. wage conditions while a Bakersfield install reflects the Central Valley market
Over thousands of California takeoffs, CountBricks has documented the following ranges for a standard 33-inch stainless drop-in sink with no layout changes:
• Basic swap, existing plumbing alignment: $450-$650
• Swap plus disposal install: $650-$900
• Undermount sink in stone countertop: $900-$1,400 (includes cut, polish and re-support)
• Apron-front retrofit with cabinet modification: $1,400-$2,200
These figures reflect turnkey kitchen sink installation cost, including labor, mid-grade fixtures, rough-in materials and site protection. Because CountBricks quotes in real time, your actual proposal may sit slightly lower or higher based on supply-chain pricing the day we generate your estimate.
1. Voice Capture – During a short call, you describe the scope and upload smartphone photos or blueprints.
2. AI Takeoff – Our software measures cabinet openings, counter thickness and rough plumbing from the images.
3. Smart Database – CountBricks cross-checks over 12,000 regional cost items for sinks, valves, fittings and labor.
4. Live Estimate – In under five minutes, you receive a line-item kitchen sink installation cost with material and labor separated.
5. One-Click Scheduling – Approve the quote, and our residential field team is automatically scheduled with the right materials list.
• No allowance guesswork – every flange, trap adapter and silicone tube is pre-counted
• Current pricing – our API updates supplier costs nightly, so you never pay yesterday’s inflated markup
• Fewer change orders – detailed scoping catches hidden tasks such as shut-off valve replacement before work starts
• Faster project cycle – because the estimate, invoice and crew assignment are handled in one ecosystem, a typical kitchen sink install can move from quote to completion within 48 hours
• Opt for drop-in over undermount if the existing countertop already has lip coverage and you want to reduce fabrication fees
• Schedule installs mid-week; Monday supply runs and Friday traffic can extend crew hours in busy metros
• Bundle tasks – adding a dishwasher air-gap or installing a faucet at the same time minimizes duplicate trip charges
• Let CountBricks handle material procurement; our bulk purchasing often beats big-box retail prices by 8-12 %
• Approve estimates within 24 hours to lock in quoted sink and fixture costs before supplier surcharges shift

Small leaks around the rim or under the basin can often be solved with new gaskets or plumber’s putty for under $50. However, if you notice these signs, full replacement is usually more cost-effective:
• Enamel chips exposing rust
• Undermount clips pulling loose from stone
• Repeated drain basket failures
• Lifestyle changes that demand a deeper or workstation sink
A CountBricks technician can assess these issues during a quick video call and help you weigh repair cost against full installation cost.
CountBricks partners with leading home-improvement financing platforms to offer same-day credit decisions up to $25,000, perfect for homeowners bundling sink replacement with a larger kitchen refresh. You can also split payments into milestone draws directly through the CountBricks dashboard.

Homeowners often ask whether labor or material drives kitchen sink installation cost. Across thousands of CountBricks residential projects, the breakdown typically sits at 60 % labor and 40 % materials. That ratio changes as complexity rises. An apron-front retrofit, for instance, can flip to 70 % labor because carpenters must notch cabinetry and reinforce face frames.
• Site prep: floor coverings, dust barriers, sink removal and disposal
• Plumbing: shut-offs, supply lines, P-trap assembly, vent checks and pressure tests
