Is your bathroom faucet dripping nonstop or barely trickling? You’re not alone—and you’re probably wondering, how long for a plumber to replace a bathroom faucet? Whether you’re dealing with corrosion, leaks, or just want a modern upgrade, knowing the timeline helps you plan your day (or weekend) without stress. In this guide, we’ll break down exactly what to expect—from scheduling to cleanup—with real-world insights from licensed pros.
How Long Does It Take a Plumber to Replace a Bathroom Faucet?
On average, a professional plumber takes 30 minutes to 2 hours to replace a standard bathroom faucet. But that range depends on several key factors:
- Faucet type (widespread, centerset, single-hole, wall-mounted)
- Existing plumbing condition (corrosion, outdated pipes, accessibility)
- Whether it’s a like-for-like swap or a full redesign
- Unexpected issues (stripped screws, hidden leaks, incompatible fittings)
According to a 2024 survey by HomeAdvisor, 78% of plumbers complete a straightforward faucet replacement in under 90 minutes. Complex jobs—like switching from a 3-hole to a single-hole setup—can stretch to 2–3 hours due to extra cutting, sealing, or pipe adjustments.
💡 Pro Tip: If you’re replacing an old faucet yourself first, don’t disconnect supply lines until the new one is confirmed compatible. Mismatched connections are a top cause of delays.
What Factors Affect Replacement Time?
Let’s dive into the variables that can speed up—or slow down—the job.
1. Faucet Configuration Matters
| Faucet Type | Avg. Installation Time | Notes |
|---|---|---|
| Centerset (4″) | 30–60 min | Most common in older homes; easy swap |
| Widespread (8″+) | 45–90 min | Requires precise alignment of handles & spout |
| Single-Hole | 30–75 min | Sleek but may need deck plate for old holes |
| Wall-Mounted | 2–4 hours | Involves opening walls; often needs permits |

2. Age and Condition of Your Plumbing
Homes built before 1980 often have galvanized steel pipes, which corrode over time. If your shutoff valves are frozen or supply lines are brittle, the plumber may need to replace those too—adding 30–60 minutes.
“I’ve seen jobs double in time because the valve snapped when turned,” says Marcus Lee, master plumber with 15 years of experience in Chicago. “Always test your shutoffs before calling a pro.”
3. Access Under the Sink
Cramped cabinets, stored cleaning supplies, or poor lighting can slow work. Plumbers appreciate a clear workspace—so empty the vanity cabinet the night before to save time (and money).
Step-by-Step: What Happens During a Faucet Replacement?
Here’s exactly what a licensed plumber does—so you know what you’re paying for:
- Shut Off Water Supply
- Closes hot and cold shutoff valves under the sink.
- Opens faucet to drain residual water.
- Disconnect Supply Lines
- Uses adjustable wrenches to detach flexible hoses (typically 3/8″ compression fittings).
- If lines are corroded, may cut and replace with new braided stainless steel lines (~$10–$20 each).
- Remove Old Faucet
- Unscrews mounting nuts (often 1–2 located beneath the sink deck).
- Lifts out faucet assembly. May require penetrating oil if rusted.
- Clean & Prep Surface
- Removes old plumber’s putty or silicone sealant.
- Wipes area dry—critical for leak-free resealing.
- Install New Faucet
- Applies new sealant (silicone for stone/marble; putty for porcelain).
- Inserts faucet through deck holes, secures with mounting hardware.
- Tightens nuts evenly to avoid cracking sink.
- Reconnect & Test
- Attaches new supply lines (hand-tight + 1/4 turn with wrench).
- Turns water back on slowly.
- Checks for leaks at connections and spout for 5–10 minutes.
⚠️ Never overtighten fittings—this is the #1 cause of cracked valves and leaks. A snug fit is enough.

DIY vs Hiring a Plumber: Time & Risk Comparison
Thinking of doing it yourself? Here’s a reality check:
| Factor | DIY Attempt | Professional Plumber |
|---|---|---|
| Time Required | 2–4 hours (first-timers) | 30–120 minutes |
| Tools Needed | Basin wrench, torch (sometimes) | Full kit + diagnostic tools |
| Risk of Leaks | High (if inexperienced) | Very low (<2% callback rate) |
| Warranty | None | Often 1-year labor warranty |
| Cost (2026 avg.) | $50–$150 (faucet only) | $150–$350 (full service) |
While DIY saves money upfront, HomeServe reports that 34% of DIY plumbing fixes lead to secondary damage—like water stains, mold, or ruined cabinetry—costing 3x more to repair.
How to Prepare for Your Plumber’s Visit (Save Time & Money)
Maximize efficiency with these prep steps:
✅ Clear the area – Remove everything from under the sink.
✅ Take photos – Snap pics of current faucet and connections for reference.
✅ Know your faucet model – Check manufacturer name on base or handle.
✅ Have access ready – Ensure parking and entry aren’t blocked.
✅ Ask about disposal – Some plumbers haul away old fixtures for free.
Most reputable companies offer same-day or next-day appointments for simple jobs like this—especially if booked online before noon.
FAQ Section
Q1: Can a plumber replace a bathroom faucet the same day?
Yes! Most local plumbing services offer same-day faucet replacement if scheduled early. Simple swaps often take less than an hour, making them ideal for quick service calls.
Q2: How much does it cost to replace a bathroom faucet professionally?
In 2026, average costs range from $150 to $350, including labor and mid-tier faucet ($80–$200). High-end designer faucets (e.g., Moen Align, Delta Trinsic) may push total cost to $500+.
Q3: Do I need to turn off the main water supply?
Usually not. Bathroom sinks have individual shutoff valves under the vanity. Only if those are broken or missing will the plumber shut off the main line—adding ~15 minutes to the job.
Q4: How long should a new faucet last?
A quality faucet lasts 10–15 years with proper maintenance. Ceramic disc cartridges (standard in modern faucets) outperform older rubber washers by reducing leaks and wear.
Q5: Can I reuse my old supply lines?
Not recommended. Flexible supply lines degrade over time. The Uniform Plumbing Code advises replacing them every 5–8 years. Most plumbers include new lines in their service.
Q6: What if my sink has three holes but I bought a single-hole faucet?
You’ll need a deck plate (escutcheon)—a metal cover that hides unused holes. Most single-hole faucets include one, but verify before purchase.
Conclusion
So, how long for a plumber to replace a bathroom faucet? Typically under two hours—often closer to one—if everything goes smoothly. By understanding the variables (faucet type, plumbing age, access), you can set realistic expectations and even speed up the process with smart prep.
A professional replacement isn’t just about convenience—it’s about preventing costly water damage and ensuring your new fixture performs flawlessly for years. Plus, many plumbers offer warranties, giving you peace of mind no YouTube tutorial can match.
