Replacing a kitchen faucet might seem simple—until you’re elbow-deep in tangled supply lines or dealing with a stubborn old valve. If you’re asking, “What does a plumber charge to install a kitchen faucet?”, you’re not alone. Homeowners across the U.S. face this exact question every year, whether upgrading for style, fixing a leak, or renovating their kitchen. The good news? Professional installation ensures safety, prevents water damage, and often comes with a warranty. Let’s break down exactly what you can expect to pay—and why.
How Much Does It Cost to Hire a Plumber for Faucet Installation?
On average, a licensed plumber charges between $150 and $400 to install a kitchen faucet in the U.S. as of 2024, according to data from HomeAdvisor and Angi. This includes labor, basic materials (like supply lines or mounting hardware), and disposal of the old unit.
However, your final bill can vary widely based on several factors:
Geographic location: Labor rates in New York City or San Francisco can be 30–50% higher than in rural Midwest towns.
Faucet complexity: A single-handle pull-down faucet with a built-in sprayer takes longer to install than a basic two-handle model.
Existing plumbing condition: Corroded pipes, outdated shut-off valves, or missing mounting hardware may require extra work.
Emergency or after-hours service: Weekend or evening calls often incur a 20–50% surcharge.
💡 Pro Tip: Always get 2–3 written estimates before hiring. Reputable plumbers offer free in-person or virtual quotes.
What’s Included in a Standard Faucet Installation?
A professional installation typically covers:
Shutting off the water supply and draining residual pressure.
Removing the old faucet (including disconnecting supply lines and sprayer hoses).
Cleaning the sink surface and inspecting for damage or corrosion.
Installing the new faucet with proper sealant (e.g., plumber’s putty or silicone).
Connecting hot and cold water lines using new braided stainless-steel supply hoses (recommended for durability).
Testing for leaks and ensuring proper water flow and temperature control.
Disposing of the old faucet responsibly.
Most plumbers spend 1 to 2 hours on a standard job. If your sink requires modifications (e.g., drilling new holes for a single-hole faucet), expect additional labor time and cost.

Adds credibility for future buyers
While DIY can save money, a single leak can cause thousands in water damage. According to the Insurance Information Institute, plumbing failures are among the top causes of homeowner insurance claims. If you’re unsure about your skills, it’s worth paying for peace of mind.
📌 Note: Some faucet manufacturers (like Moen or Delta) void warranties if installation isn’t done by a licensed plumber—always check your product manual.
Factors That Increase Installation Costs
Not all faucet swaps are created equal. Watch out for these common cost boosters:
Old or corroded shut-off valves: Replacing these adds $75–$150.
Need for a new sink: If you’re changing from a 3-hole to a single-hole faucet, you may need a deck plate—or a new sink.
Hard water buildup: Mineral deposits can seize connections, requiring specialized tools or pipe replacement.
Permit requirements: Rare for faucet swaps, but some cities require permits for any plumbing modification (check local codes).
For context, the U.S. Environmental Protection Agency notes that kitchen faucets account for nearly 8% of indoor home water use—so investing in a high-efficiency model (look for the WaterSense label) can lower utility bills long-term. Learn more about WaterSense standards on Wikipedia .
Step-by-Step: What Happens During Professional Installation
If you’re curious (or want to prep your kitchen), here’s exactly how a plumber handles the job:
Turn off water supply at the shut-off valves under the sink (or main house valve if needed).
Open the faucet to release pressure and drain remaining water.
Disconnect supply lines using an adjustable wrench—place a towel underneath to catch drips.
Remove mounting nuts securing the old faucet from beneath the sink.
Lift out the old faucet and clean the sink surface thoroughly.
Insert new faucet through mounting holes; secure with mounting hardware from below.
Attach new supply lines (typically 3/8″ compression fittings) to hot and cold inlets.
Turn water back on slowly, check for leaks at all connections, and test spray function (if applicable).
Adjust handle alignment and ensure smooth operation.
Most pros use Teflon tape on threaded connections and braided stainless hoses—never cheap plastic lines that crack over time.
FAQ Section
Q: Can I install a kitchen faucet myself? A: Yes—if you’re comfortable with basic tools and have shut-off valves that work. However, if you encounter leaks, low water pressure, or cross-threaded fittings, stop and call a pro. Mistakes can lead to costly water damage.
Q: How long does faucet installation take? A: Typically 60–120 minutes for a standard replacement. Complex setups (e.g., adding a filtered water line or garbage disposal integration) may take up to 3 hours.
Q: Do plumbers charge by the hour or per job? A: Most offer flat-rate pricing for faucet installation (e.g., $225 all-in). Hourly rates ($75–$150/hour) are more common for troubleshooting or unexpected repairs.
Q: Should I replace supply lines when installing a new faucet? A: Yes, always. Old rubber or plastic lines degrade over time. Braided stainless-steel hoses ($10–$20/pair) are safer and last 10+ years.
Q: Does faucet brand affect installation cost? A: Not directly—but high-end models (e.g., touchless or smart faucets) may require electrical work or special fittings, increasing labor time.
Q: Will my homeowner’s insurance cover a leak from a DIY faucet install? A: Possibly not. Many policies exclude damage from “improper installation by unlicensed individuals.” When in doubt, hire a licensed plumber.
Conclusion
So, what does a plumber charge to install a kitchen faucet? Realistically, $150–$400 for a reliable, leak-free job that protects your home and investment. While DIY might seem tempting, the risks often outweigh the savings—especially when a pro can complete the work in under two hours with guaranteed results.
Whether you’re upgrading for style, efficiency, or function, professional installation ensures your new faucet performs flawlessly for years.
