Replacing or installing a new bathroom vanity can instantly refresh your space—but it often comes with plumbing work you can’t DIY. If you’re asking, “How much does a plumber charge to install a vanity?”, you’re not alone. Many homeowners are surprised by hidden costs or unclear quotes. In this guide, we’ll break down exactly what to expect in 2025, including average costs, what affects pricing, and how to avoid overpaying—all based on real data and expert insights.
What’s the Average Cost to Install a Vanity?
According to HomeAdvisor’s 2025 Cost Guide, the national average for a plumber to install a bathroom vanity ranges from $200 to $650, with most homeowners paying around $400. This includes labor, minor plumbing adjustments, and connecting the sink, faucet, and drain.
However, your actual cost depends on several key factors:
- Type of vanity (pre-assembled vs. custom)
- Plumbing complexity (moving pipes vs. same-location install)
- Geographic location (urban vs. rural labor rates)
- Additional services (removing old vanity, fixing leaks, etc.)
💡 Pro Tip: If your new vanity matches the footprint of the old one and uses the same plumbing layout, you’ll save 30–50% on labor.
What Factors Affect Vanity Installation Costs?
1. Vanity Type and Size
- Pre-assembled vanities: Easiest and cheapest to install ($200–$400).
- Custom or floating vanities: Require precise leveling and wall mounting—costs jump to $500–$900.
- Double-sink vanities: Often need new supply lines and drain rerouting, adding $150–$300.
2. Plumbing Modifications
If your new vanity doesn’t align with existing pipes, the plumber may need to:
- Reroute water supply lines
- Adjust the P-trap or drainpipe
- Install new shut-off valves
These modifications can add $100–$300 to your bill.
3. Removal of Old Vanity
Most plumbers charge $50–$150 to remove and dispose of your old unit—especially if it’s glued, tiled-in, or connected to cabinetry.
4. Location Matters
Labor rates vary widely by region:
| Midwest | $65–$85/hr | $250–$450 |
| West Coast | $90–$120/hr | $400–$700 |
| Northeast | $85–$110/hr | $350–$650 |
| South | $60–$80/hr | $200–$400 |

Step-by-Step: What Happens During a Vanity Installation?
Even if you’re not doing it yourself, understanding the process helps you spot fair pricing and avoid scams. Here’s what a professional plumber typically does:
- Shut off water supply (usually under the sink or at the main valve).
- Disconnect old plumbing—faucet, supply lines, and P-trap.
- Remove existing vanity (if applicable), taking care not to damage flooring or walls.
- Prepare the new space: Level the floor, patch holes, or install backing for wall-mounted units.
- Assemble the new vanity (if not pre-built) and position it precisely.
- Reconnect plumbing: Attach new or existing supply lines, install faucet, and connect drain.
- Test for leaks by turning water back on and running the faucet for 5–10 minutes.
- Clean up and confirm everything functions smoothly.
⚠️ Warning: Skipping leak testing is a red flag. Always insist on a full water test before paying.
DIY vs. Hiring a Plumber: Is It Worth It?
Many homeowners consider DIY to save money—but plumbing mistakes can cost thousands in water damage.
| Cost | $0–$100 (tools only) | $200–$650 |
| Time | 3–6 hours (for beginners) | 1–2 hours |
| Risk | High (leaks, misalignment) | Low (licensed & insured) |
| Warranty | None | Usually 30–90 days |
According to the National Kitchen and Bath Association (NKBA), 68% of DIY plumbing projects in bathrooms require professional correction within a year.
📌 When to DIY: Only if you’re replacing a drop-in sink in the exact same spot with no pipe changes—and you own basic tools like basin wrenches and pipe tape.
For anything else, hire a licensed plumber. You can verify credentials via your state’s contractor licensing board or Wikipedia’s overview of plumbing regulations .
How to Save Money on Vanity Installation
You don’t have to overpay. Try these expert-backed strategies:
- Bundle services: Ask if your plumber offers discounts for installing multiple fixtures (e.g., vanity + toilet).
- Schedule off-peak: Avoid weekends or holidays—many plumbers charge 20–30% more for emergency or weekend rates.
- Buy your own vanity: Some plumbers mark up materials by 15–25%. Purchase from a retailer and only pay for labor.
- Get 3+ quotes: Compare not just price, but scope of work. One quote might include disposal; another might not.
FAQ: Your Top Questions Answered
Q1: Does vanity installation include faucet installation?
A: Usually, yes—but confirm upfront. Most plumbers include faucet mounting and supply line connection in their quote. If you’re reusing an old faucet, labor may be slightly less.
Q2: How long does it take a plumber to install a vanity?
A: For a standard same-location install: 1 to 2 hours. If pipes need rerouting or the floor requires leveling, it may take 3–4 hours.
Q3: Can a handyman install a vanity instead of a plumber?
A: In many states, no—if plumbing lines are altered, a licensed plumber is legally required. Handymen can assemble cabinets but often can’t legally connect water lines. Check local codes first.
Q4: What’s NOT included in a standard vanity install quote?
A: Common exclusions:
- Tile or drywall repair
- New shut-off valves (if old ones are corroded)
- Upgrading to braided stainless supply lines
- Hauling away old vanity (unless specified)
Q5: Should I tip my plumber?
A: Tipping isn’t expected but appreciated for excellent service—$20–$50 is common for jobs under $500. Better yet: leave a 5-star review!
Q6: How do I know if I’m being overcharged?
A: Compare your quote to national averages (see above). If a plumber charges more than $120/hour without justification (e.g., emergency service), get a second opinion.
Final Thoughts
Knowing how much a plumber charges to install a vanity empowers you to budget wisely, avoid surprises, and choose the right professional. On average, expect to pay $200–$650, but smart planning—like matching your new vanity to your old layout or scheduling during weekdays—can keep costs on the lower end.
A well-installed vanity not only looks great but prevents costly leaks and adds value to your home. So don’t rush the decision—invest in quality work the first time.
