How Much for Plumber to Replace Faucet in Bathtub? (2026 Guide)

Is your bathtub faucet dripping nonstop or stuck in the “on” position? You’re not alone—and you’re probably wondering, “How much for plumber to replace faucet in bathtub?” Whether it’s due to wear, leaks, or an outdated design, replacing a bathtub faucet is a common home improvement task. But costs can vary widely depending on several key factors. In this guide, we’ll break down everything you need to know—from average prices to hidden fees—so you can budget wisely and avoid overpaying.

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

Most U.S. homeowners pay between $200 and $500 for a professional plumber to replace a bathtub faucet, according to data from HomeAdvisor and Angi (formerly Angie’s List) in early 2026. This includes both labor and materials for a standard single-handle or double-handle tub spout with diverter.

However, your final bill could be as low as $120 for a simple swap or exceed $800 if your plumbing system requires extensive modifications or if you choose high-end fixtures.

💡 Pro Tip: Labor typically accounts for 60–70% of the total cost. Always ask for a detailed quote before work begins.

What Factors Affect the Cost?

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

1. Type of Faucet System

• Tub-only spout: Simplest and cheapest ($120–$300)
• Tub/shower combo with diverter: More complex ($250–$500)
• Thermostatic or pressure-balanced valves: Premium systems ($400–$900+)

2. Accessibility & Wall Access

If your faucet is behind tile or drywall, the plumber may need to cut into the wall—adding $100–$300 for access and patching.

3. Plumbing Condition

Old galvanized pipes or corroded valves may require additional repairs. According to the U.S. Department of Energy, homes built before 1980 are more likely to have outdated plumbing that complicates installations.

4. Fixture Quality

• Budget faucets: $30–$80
• Mid-range (Moen, Delta, Kohler): $80–$250
• Luxury brands (Grohe, Hansgrohe): $250–$600+

5. Location & Local Labor Rates

Plumbers in cities like New York or San Francisco charge 20–40% more than in rural areas. The national average labor rate is $75–$150/hour, with most jobs taking 1.5–3 hours.

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

Many homeowners consider DIY to save money—but is it smart?

⚠️ Warning: A poorly installed faucet can cause water damage, mold, or even void your home insurance. The International Association of Certified Home Inspectors (InterNACHI) reports that 14% of water damage claims stem from DIY plumbing errors.

For most people, hiring a licensed plumber is the safer, smarter choice—especially if your setup involves hidden valves or older plumbing.

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

Here’s what a professional plumber typically does during a standard bathtub faucet replacement:

1. Shut off water supply – Usually at the main valve or dedicated shutoff.
2. Drain residual water – Open the faucet to release pressure and remaining water.
3. Remove old fixture – Use a basin wrench or spout puller; may require cutting access if behind tile.
4. Inspect valve & pipes – Check for corrosion, leaks, or outdated parts (e.g., compression vs. sweat fittings).
5. Install new faucet/spout – Secure with plumber’s tape or pipe dope; ensure proper alignment.
6. Test for leaks – Turn water back on, run hot/cold for 5–10 minutes, check connections.
7. Clean up & restore area – Patch drywall if needed, remove debris.

Most reputable plumbers complete this in under 3 hours. If they discover major issues (like a cracked valve body), they’ll pause and get your approval before proceeding.

How to Save Money Without Sacrificing Quality

You don’t have to overpay. Try these expert-backed strategies:

• Bundle services: Replace your faucet while doing other bathroom work (e.g., recaulking, showerhead upgrade) to reduce labor fees.
• Buy your own fixture: Some plumbers let you supply the faucet, saving 10–20% on markup. Just confirm compatibility first!
• Schedule off-peak: Avoid weekends or holidays when emergency rates apply.
• Get 3 quotes: Compare transparent, line-item estimates—not just the bottom line.

📌 Note: Never choose the cheapest bid if it lacks licensing, insurance, or reviews. Verify credentials via your state’s contractor board.

Common Mistakes Homeowners Make

Avoid these costly errors:

• Ignoring the valve type: Tub faucets connect to either a stem valve or cartridge valve. Swapping without matching can cause failure.
• Skipping the permit: In some municipalities (e.g., Chicago, Seattle), plumbing changes require permits. Fines can reach $1,000+.
• Using mismatched finishes: A brushed nickel spout with chrome handles looks unprofessional and lowers resale appeal.

FAQ Section

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

A: Most replacements take 1.5 to 3 hours. Complex jobs (e.g., behind-tile access or valve replacement) may take half a day.

Q2: Can I replace just the spout, or do I need a full faucet kit?

A: If only the spout is damaged and the valve works fine, you can replace just the spout ($50–$150). But if the handle drips or won’t turn, you likely need a new valve cartridge or entire trim kit.

Q3: Do I need to replace the entire valve behind the wall?

A: Not always. If the valve body is intact and compatible with modern trims, plumbers can often reuse it. However, homes built before 1990 may need a full valve replacement for safety and efficiency.

Q4: Are bathtub faucet replacements covered by home insurance?

A: Generally, no—unless sudden water damage occurs during a covered event (e.g., burst pipe from freezing). Routine upgrades are homeowner responsibilities.

Q5: What’s the difference between a diverter and non-diverter spout?

A: A diverter spout has a small knob or button to redirect water from the tub spout to the showerhead. A non-diverter only supplies water to the tub. Using the wrong type causes poor shower pressure.

Q6: How do I know if my plumber is licensed and insured?

A: Ask for their license number and verify it on your state’s contractor licensing board website. Also request proof of liability insurance and workers’ comp.

Conclusion

Knowing how much for plumber to replace faucet in bathtub empowers you to make informed decisions, avoid scams, and protect your home from water damage. While prices range from $200 to $500 on average, the right pro ensures a leak-free, long-lasting result that adds value to your bathroom.
