Replacing a sink might seem straightforward, but hidden complexities—like plumbing rerouting, material choices, or unexpected leaks—can quickly turn it into a costly project. If you’re asking, “How much does a plumber charge to replace a sink?”, you’re not alone. Many U.S. homeowners face this exact question when upgrading their kitchen or bathroom. In this guide, we’ll break down real-world costs, explain what affects pricing, and help you avoid overpaying—all based on 2025 industry data and expert insights.
What’s the Average Cost to Replace a Sink in 2025?
According to HomeAdvisor and Angi (formerly Angie’s List), the national average cost for a professional sink replacement in the U.S. ranges from $330 to $1,150, with most homeowners paying around $650.
This includes:
- Labor (typically $45–$150/hour)
- New sink (if not supplied by homeowner)
- Removal and disposal of the old sink
- Basic plumbing adjustments
💡 Note: Costs vary significantly by location, sink type, and whether you’re replacing just the basin or the entire countertop unit.
What Factors Affect the Cost of Sink Replacement?
Several variables influence how much a plumber charges to replace a sink. Understanding these can help you budget accurately and spot potential red flags in quotes.
1. Type of Sink
- Drop-in (top-mount): Easiest to install → $150–$400 labor
- Undermount: Requires secure mounting beneath countertop → $250–$600
- Farmhouse (apron-front): Often needs cabinet modifications → $400–$900+
- Vessel sinks: Stylish but may need special faucets and drain setups → $300–$700
2. Material Matters
Common sink materials and their average installed costs:
| Stainless Steel | $200 – $500 |
| Porcelain | $250 – $600 |
| Granite Composite | $400 – $900 |
| Copper | $600 – $1,500+ |
3. Location: Kitchen vs. Bathroom
- Kitchen sink replacement: $400–$1,200 (larger, dual basins, garbage disposal)
- Bathroom sink: $250–$700 (smaller, simpler plumbing)
4. Plumbing Complexity
If your existing pipes are corroded, misaligned, or require rerouting, labor costs can jump by $100–$300. Older homes (pre-1980s) often need additional work due to outdated plumbing systems.
5. Geographic Location
Labor rates differ by region:
- Midwest: $45–$85/hour
- West Coast: $80–$150/hour
- Northeast: $75–$140/hour

DIY vs. Hiring a Professional: Which Saves More?
While YouTube tutorials make sink replacement look easy, plumbing mistakes can lead to water damage, mold, or code violations. Here’s a quick comparison:
| Cost | $100–$400 (materials only) | $330–$1,150 (full service) |
| Time Required | 3–8 hours | 1–3 hours |
| Risk of Leaks | High (if inexperienced) | Very low |
| Warranty | None | Often 1-year labor warranty |
| Resale Value Impact | May void home inspection | Adds documented improvement |
🛠️ Expert Tip: The Plumbing-Heating-Cooling Contractors Association (PHCC) recommends hiring a licensed plumber for any job involving water supply lines or drain connections. A small leak behind a cabinet can cause $2,000+ in water damage—far exceeding the cost of professional installation.

Step-by-Step: What Happens During a Professional Sink Replacement?
If you hire a plumber, here’s what to expect:
- Shut off water supply (hot and cold lines).
- Disconnect supply lines and drain pipes using adjustable wrenches.
- Remove old sink—cut sealant, detach mounting clips (for undermount), or loosen brackets.
- Inspect plumbing and countertop for damage or rot.
- Install new sink:
- Apply plumber’s putty or silicone sealant.
- Secure with mounting hardware (torque to manufacturer specs).
- Reconnect water lines and drain assembly (use Teflon tape on threads).
- Test for leaks at 60 PSI for 10 minutes.
- Clean up and dispose of old materials.
Most pros complete this in under 2 hours for standard drop-in sinks.
How to Save Money on Sink Replacement
You don’t have to sacrifice quality to stay on budget. Try these proven strategies:
- Supply your own sink: Buy during sales (e.g., Home Depot’s spring promotions).
- Bundle services: Replace faucet or garbage disposal at the same time for labor discounts.
- Get 3+ quotes: Use platforms like Angi or HomeAdvisor to compare local rates.
- Avoid weekends/holidays: Emergency or after-hours rates can be 1.5x higher.
- Check for rebates: Some municipalities offer eco-upgrade incentives for water-efficient sinks.
FAQ: Common Questions About Sink Replacement Costs
Q: Does replacing a sink increase home value?
A: Yes—especially in kitchens. A modern, functional sink improves aesthetics and functionality. According to the National Association of Realtors, kitchen updates yield ~70% ROI at resale.
Q: How long does a sink replacement take?
A: Most jobs take 1–3 hours. Complex installs (e.g., farmhouse sinks in existing cabinets) may take half a day.
Q: Can I reuse my old faucet with a new sink?
A: Sometimes—but only if the mounting holes align and the faucet isn’t corroded. Mismatched holes can compromise the seal. Most plumbers recommend upgrading both.
Q: Are plumbing permits required to replace a sink?
A: Generally no for like-for-like replacements. But if you’re moving plumbing lines or altering drainage, a permit may be needed (check local codes).
Q: What’s included in a plumber’s quote?
A: Reputable quotes should list: labor hours, materials (if provided), disposal fees, and any potential extra charges (e.g., for pipe repair).
Q: How do I know if my plumber is licensed and insured?
A: Always ask for their license number and verify it with your state’s contractor board. Insurance protects you if they cause damage during the job.
Final Thoughts: Get It Right the First Time
Knowing how much a plumber charges to replace a sink isn’t just about price—it’s about value, safety, and peace of mind.
