How Much Does a Plumber Charge to Swap a Bathroom Faucet?

Replacing a bathroom faucet might seem like a minor home upgrade—but if you’re not handy with a wrench, hiring a plumber is the smart move. So, how much does a plumber charge to swap a bathroom faucet? The answer depends on several factors, from your location to the faucet’s complexity. In this guide, we’ll break down average costs, what influences pricing, and whether you should DIY or call a pro—so you can make an informed decision without overspending.

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

Most homeowners pay between $150 and $400 for a professional to swap out a bathroom faucet, including both labor and materials. According to HomeAdvisor’s 2025 data, the national average sits at $275, with labor alone typically ranging from $100 to $250 per hour (though most jobs take just 1–2 hours).

💡 “A standard faucet replacement is one of the most common—and affordable—plumbing services,” says Marcus Lee, a licensed master plumber with over 15 years of experience in Chicago. “But hidden issues like corroded valves or outdated pipes can quickly double the bill.”

Here’s a quick cost breakdown:

Note: High-end designer faucets (e.g., Moen, Delta, Kohler) can cost $300+ alone, pushing total project costs toward $600 or more.

What Factors Affect the Cost?

Not all faucet swaps are created equal. Here’s what can raise—or lower—your final bill:

1. Type of Faucet

• Single-handle: Easiest and cheapest to install (~$150–$300 total).
• Widespread or centerset: Require precise alignment; may need extra time (~$200–$400).
• Wall-mounted: Rare in U.S. homes but complex—expect +$100–$200 for rerouting pipes.

2. Accessibility & Condition of Plumbing

Older homes often have:

• Corroded shut-off valves (may need replacement: +$50–$100)
• Outdated supply lines (require new flexible hoses: +$20)
• Limited under-sink space (slows work, increases labor)

3. Geographic Location

Labor rates vary widely:

• Low-cost areas (e.g., Midwest): $75–$125/hour
• High-cost cities (e.g., NYC, San Francisco): $150–$300/hour

Check local averages via HomeAdvisor or Angi.

4. Emergency or Weekend Service

Need it fixed tonight? After-hours fees can add 20–50% to your bill.

DIY vs Hiring a Pro: Which Saves More?

Many homeowners consider DIY to avoid labor costs—but is it worth the risk?

✅ DIY Pros:

• Save $100–$250 in labor
• Simple swaps take 30–60 minutes with basic tools
• Great learning opportunity

❌ DIY Cons:

• Risk of leaks, water damage, or voiding faucet warranty
• May lack proper tools (basin wrench, pipe thread sealant)
• No insurance if something goes wrong

🛠️ Step-by-Step DIY Guide (for confident beginners):

1. Turn off water supply under the sink (or main shutoff if no valves).
2. Drain remaining water by opening the faucet.
3. Disconnect supply lines using an adjustable wrench.
4. Remove mounting nuts beneath the sink (use a basin wrench if tight).
5. Lift out old faucet, clean the deck surface.
6. Install new faucet following manufacturer instructions—use plumber’s putty or silicone as needed.
7. Reconnect supply lines, turn water back on, and test for leaks.

⚠️ If you encounter cross-threaded fittings, mineral buildup, or no shutoff valves, stop and call a pro. One mistake could lead to $500+ in water damage.

How to Avoid Overpaying for Faucet Replacement

Smart homeowners use these strategies to keep costs fair:

• Get 3 quotes from licensed plumbers (check license via your state’s contractor board).
• Bundle services: Replacing multiple fixtures? Ask for a discount.
• Buy your own faucet: Some plumbers mark up materials by 20–30%.
• Schedule during off-peak hours: Weekday mornings are often cheapest.
• Ask about flat-rate pricing: Avoid hourly surprises—many pros offer fixed fees for standard swaps.

When to Call a Professional Immediately

Don’t wait if you notice:

• Persistent dripping after DIY attempts
• Rust or cracks in supply lines
• Low water pressure post-installation
• Water pooling under the sink

These signs indicate deeper issues that require expert diagnosis.

Most standard replacements take 45 minutes to 2 hours. Complex installations (e.g., wall-mounted or custom vanities) may take half a day.

Yes, removal and disposal of the old faucet are typically included in the quoted price. Confirm this before work begins.
