How Much Does a Plumber Charge to Change a Kitchen Faucet?

If your kitchen faucet is leaking, outdated, or just not working right, you’re probably wondering: How much does a plumber charge to change a kitchen faucet? It’s a common question—and a smart one. Replacing a faucet might seem simple, but hiring the wrong person (or going DIY without the right tools) can lead to costly mistakes. In this guide, we’ll break down everything you need to know about plumbing costs, labor rates, and what actually affects your final bill—so you can make an informed decision without overspending.

What’s the Average Cost to Replace a Kitchen Faucet?

According to HomeAdvisor’s 2025 data, the average cost to replace a kitchen faucet ranges from $160 to $375, with most homeowners paying around $270. This includes both labor and materials. However, prices can vary widely based on your location, faucet type, and whether additional plumbing work is needed.

💡 Pro Tip: Labor typically accounts for 60–70% of the total cost. The faucet itself may cost anywhere from $50 (basic models) to over $500 (premium brands like Moen, Delta, or Kohler).

What Factors Affect the Cost?

Several variables influence how much you’ll pay. Here’s what plumbers consider when giving you a quote:

1. Type of Faucet

• Standard single-handle faucets: Easiest and cheapest to install.
• Pull-down or pull-out sprayers: Require more complex hose routing.
• Touchless or smart faucets: May need electrical connections or calibration.

2. Labor Rates by Region

Plumbers in urban areas (e.g., New York City, San Francisco) often charge $100–$150/hour, while rural areas may see rates as low as $60–$85/hour. Most replacements take 1–2 hours, so expect to pay $80–$250 in labor alone.

3. Existing Plumbing Condition

If your sink has old valves, corroded pipes, or incompatible fittings, the plumber may need to:

• Replace shut-off valves
• Repair pipe threads
• Install new supply lines

These add-ons can increase your bill by $50–$150.

4. DIY vs. Hiring a Pro

While YouTube tutorials make it look easy, 30% of DIY faucet installations result in leaks or damage within 6 months (per a 2024 study by the National Association of Home Builders). If you’re not confident with wrenches and Teflon tape, professional installation is worth the peace of mind.

Step-by-Step: What Happens During a Professional Faucet Replacement?

Here’s exactly what a licensed plumber will do—so you know you’re getting your money’s worth:

1. Turn off water supply – Locate and shut off the hot and cold valves under the sink.
2. Disconnect supply lines – Use adjustable wrenches to detach the hoses.
3. Remove old faucet – Unscrew mounting nuts from beneath the sink.
4. Clean the sink surface – Remove old caulk or debris to ensure a watertight seal.
5. Install new faucet – Insert through sink holes, secure with mounting hardware.
6. Connect supply lines – Attach new braided stainless steel hoses (recommended for durability).
7. Test for leaks – Turn water back on and run both hot and cold for 2–3 minutes.
8. Final inspection – Check spray function (if applicable) and ensure no drips.

⚠️ Note: Always use new supply lines—reusing old ones is a leading cause of post-installation leaks.

Cost Breakdown: DIY vs. Professional Installation

While DIY saves money upfront, most plumbers offer a 1-year labor warranty—something you won’t get if you go solo. Plus, if something goes wrong, water damage repairs can cost $1,000+.

When Should You Call a Plumber?

You should definitely hire a pro if:

• Your home was built before 1980 (older pipes may be fragile)
• You have a non-standard sink (e.g., farmhouse, 3-hole setup)
• The new faucet requires an electrical outlet (for touchless models)
• You lack basic tools like basin wrenches or pipe thread sealant

For reference, modern faucets often require precise torque settings and alignment—tasks best left to experienced hands.

How to Save Money Without Sacrificing Quality

1. Buy your own faucet – Plumbers often mark up fixtures by 20–30%. Purchase from a trusted retailer (like Home Depot or Ferguson) and ask the plumber to install it.
2. Bundle services – Need a garbage disposal fixed too? Ask for a package rate.
3. Schedule off-peak – Avoid weekends or holidays when emergency rates apply.
4. Check for rebates – Some utility companies offer discounts for installing WaterSense-labeled faucets (learn more on EPA’s WaterSense program).

FAQ Section

Q1: How long does it take a plumber to replace a kitchen faucet?

A: Most standard replacements take 60 to 90 minutes. Complex setups (e.g., adding a soap dispenser or switching from 3-hole to single-hole) may take up to 2.5 hours.

Q2: Do I need to replace the sink when changing the faucet?

A: No, unless your sink is damaged or the new faucet doesn’t match the existing hole configuration. Adaptor plates can cover extra holes.

Q3: Can a handyman replace a kitchen faucet instead of a plumber?

A: Yes—but only if they’re licensed for plumbing work in your state. In many states (like California or Texas), faucet replacement involving water lines requires a licensed plumber. Always verify credentials.

Q4: What’s included in a plumber’s service call fee?

A: Most plumbers charge a $50–$100 diagnostic or trip fee, which is often waived if you proceed with the job. Always ask upfront.

Q5: Are there hidden costs I should watch for?

A: Watch out for:

• Charges for old valve replacement
• “Emergency” surcharges (even during business hours)
• Disposal fees for the old faucet
  Always request a written estimate before work begins.

Q6: How do I choose the right faucet for my kitchen?

A: Consider:

• Mount type (deck-mounted vs. wall-mounted)
• Spout height and reach (especially for deep sinks)
• Finish (brushed nickel resists fingerprints better than chrome)
• Water efficiency (look for WaterSense certification)

Conclusion

Now you know exactly how much a plumber charges to change a kitchen faucet—and why those costs vary. Whether you’re upgrading for style, fixing a drip, or improving water efficiency, understanding the real expenses helps you avoid surprises and choose wisely.
