How 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If your kitchen faucet is leaking, outdated, or just not working right, you’re probably wondering: How does a plumber charge to change a kitchen faucet? You’re not alone. Many homeowners face this exact question—especially when trying to budget for home repairs without getting overcharged. The good news? Understanding how plumbing pricing works can save you time, money, and stress. Let’s break it down clearly and fairly.

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

Most U.S. homeowners pay between $150 and $400 to have a licensed plumber replace a kitchen faucet, according to data from HomeAdvisor (2025). This includes both labor and materials if you’re purchasing the faucet through the plumber.

However, prices can vary widely based on:

• Your location (urban vs. rural)
• The type of faucet you choose
• Whether additional plumbing work is needed
• The plumber’s hourly rate or flat-fee structure

💡 Pro Tip: Always get at least 2–3 quotes before hiring. Rates in cities like New York or San Francisco can be 30–50% higher than national averages.

Do Plumbers Charge by the Hour or Per Job?

This is one of the most common “People Also Ask” questions—and the answer depends on the plumber and the job complexity.

Hourly Rate Model

• Typical range: $75–$150/hour
• Best for: Jobs with unknown variables (e.g., corroded pipes, hidden leaks)
• You pay only for time spent, but total cost can be unpredictable

Flat-Rate (Per-Job) Pricing

• Typical range: $120–$300 for standard faucet replacement
• Best for: Straightforward replacements with no surprises
• Offers price certainty upfront

📌 Expert Insight: “Flat-rate pricing builds trust,” says Marcus Lee, a master plumber with 18 years of experience in Chicago. “Customers know exactly what they’ll pay before we even turn the water off.”

What Factors Affect the Final Price?

Not all faucet changes are created equal. Here’s what can increase (or decrease) your bill:

For example, replacing a simple single-handle faucet in a modern kitchen might take 45–60 minutes. But if you’re upgrading from a 2-handle system to a pull-down sprayer with a new mounting plate, that could take 2+ hours—especially if the sink wasn’t pre-drilled for extra holes.

Step-by-Step: How a Professional Replaces a Kitchen Faucet

Curious what you’re paying for? Here’s the standard process a licensed plumber follows:

1. Shut Off Water Supply
   Locate and close the hot and cold shutoff valves under the sink. If none exist, the main house valve is used.
2. Disconnect Supply Lines
   Use an adjustable wrench to detach the flexible supply hoses from the faucet tailpieces.
3. Remove Old Faucet
   Loosen the mounting nuts (usually 1–2) from underneath. Lift out the old unit.
4. Clean & Prep Surface
   Wipe the sink deck to remove old putty or debris. Check for damage or rust.
5. Install New Faucet
   Insert the new faucet through the mounting hole(s). Secure with mounting hardware from below.
6. Connect Supply Lines
   Attach new braided stainless steel hoses (recommended for durability) to hot and cold inlets.
7. Test for Leaks
   Turn water back on slowly. Run both hot and cold for 1–2 minutes. Check all connections with a dry paper towel.
8. Final Adjustments
   Ensure sprayer function (if applicable), align handles, and clean up tools.

⏱️ Time Note: A skilled plumber typically completes this in under 90 minutes—unless complications arise.

DIY vs. Hiring a Plumber: Is It Worth It?

Many homeowners consider doing it themselves to save money. But is it wise?

✅ Pros of DIY:

• Save $100–$250 in labor
• Sense of accomplishment
• Full control over parts

❌ Cons of DIY:

• Risk of leaks, water damage, or voiding warranty
• May lack proper tools (e.g., basin wrench)
• No insurance if something goes wrong

🛠️ Reality Check: According to a 2024 Angi survey, 22% of DIY plumbing attempts resulted in costly callbacks to professionals—often due to improper sealant use or cross-threaded fittings.

Unless you’re comfortable working in tight spaces and understand basic plumbing principles, hiring a pro is often the smarter long-term choice.

Hidden Costs to Watch Out For

Even with transparent pricing, surprises can pop up. Be aware of these potential add-ons:

• Disposal Fees: Some plumbers charge $10–$20 to haul away your old faucet.
• Supply Line Replacement: Old rubber hoses should be replaced with braided steel ($15–$30/pair).
• Shutoff Valve Repair: If valves are stuck or leaking, replacement adds $75–$150.
• Sink Modifications: Adding a soap dispenser or switching from 3-hole to single-hole may require drilling or adapter plates.

Always ask: “Is this quote all-inclusive?” before work begins.

FAQ Section

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

A: Most standard replacements take 45 to 90 minutes. Complex installs (e.g., adding a sprayer or changing sink configuration) may take 2–3 hours.

Q2: Can I reuse my old supply lines?

A: Not recommended. Flexible supply lines degrade over time. Most plumbers install new braided stainless steel lines to prevent future leaks.

Q3: Do I need to buy the faucet myself?

A: You can—but many plumbers offer discounted pricing through trade suppliers. Compare retail vs. their quote. Just ensure the model is compatible with your sink.

Q4: Will my homeowner’s insurance cover faucet replacement?

A: Generally, no—unless the replacement is due to a covered water damage claim (e.g., burst pipe). Routine upgrades are out-of-pocket.

Q5: What’s the cheapest way to replace a kitchen faucet?

A: Buy a mid-range faucet ($80–$150) during a sale and hire a local plumber offering flat-rate service. Avoid big-box store “installation packages”—they often subcontract and mark up labor.

Q6: How do I know if my plumber is charging fairly?

A: Check their license (required in most states), read recent reviews, and compare their quote to national averages. A fair price includes clear breakdowns of labor, materials, and any extras.

Conclusion

Now you know exactly how a plumber charges to change a kitchen faucet—and what influences the final cost. Whether you’re dealing with a dripping handle or upgrading to a sleek new design, understanding pricing structures helps you avoid surprises and make informed decisions.

💡 Remember: A well-installed faucet not only improves daily convenience but can also boost your home’s value and prevent water waste (the average leaky faucet wastes 3,000+ gallons per year, per the EPA!).
