You’ve picked out the perfect new faucet—sleek, modern, and just right for your kitchen or bathroom. But now you’re wondering: Will a plumber install a faucet I bought? The short answer is yes, most licensed plumbers will happily install a faucet you’ve purchased yourself. In fact, many homeowners choose this route to save money or get exactly the fixture they want. But before you call a pro, there are a few key things you should know to avoid delays, extra fees, or installation headaches.
Do Plumbers Install Customer-Supplied Faucets?
Yes—most professional plumbers will install a faucet you’ve already purchased. However, policies can vary by company or independent contractor. Some plumbers prefer to supply their own fixtures to ensure compatibility, warranty coverage, and quality control. Others are happy to work with your choice, especially if it’s from a reputable brand like Moen, Delta, or Kohler.
💡 Pro Tip: Always confirm the plumber’s policy before buying your faucet. A quick call or email can save you time and potential return fees.
According to a 2023 survey by HomeAdvisor, 72% of plumbers reported that they regularly install customer-supplied fixtures, though nearly half (48%) charge a small surcharge for handling non-standard or complex models.
What to Check Before Buying Your Faucet
Not all faucets are created equal—and not all will fit your existing sink or plumbing setup. To avoid costly mistakes, verify the following before you click “Buy Now”:
- Mounting Configuration:
- Is your sink a single-hole, 3-hole, or 4-hole setup?
- Does your faucet require a deck plate (escutcheon)?
- Valve Type:
- Compression, ball, cartridge, or ceramic disc? Most modern faucets use ceramic disc valves for durability.
- Water Supply Lines:
- Are your existing supply lines compatible with the new faucet’s connections? Many new faucets use 3/8″ compression fittings.
- Clearance & Spout Reach:
- Measure from the center of your sink to the back wall or backsplash. Ensure the spout won’t hit anything when turned on.
- Finish & Style:
- While aesthetic, mismatched finishes (e.g., brushed nickel vs. chrome) can look jarring if you have other fixtures nearby.

Pros and Cons: Buying Your Own Faucet vs. Letting the Plumber Supply It
| Cost Control | ✅ You choose budget & brand | ❌ Often marked up 20–50% |
| Warranty | ❌ You handle manufacturer claims | ✅ Plumber may cover labor + parts |
| Compatibility | ❌ Risk of mismatch or return | ✅ Guaranteed fit & function |
| Convenience | ❌ You shop, transport, store | ✅ One-stop service |
| Installation Speed | ❌ May delay if wrong model | ✅ Faster, no waiting |
Bottom line: If you’re confident in your selection and have time to research, buying your own faucet can save $50–$150. But if you value peace of mind and speed, letting the plumber supply it might be worth the premium.
How Much Does It Cost to Have a Plumber Install a Faucet You Bought?
The average cost to install a faucet in the U.S. ranges from $150 to $350, depending on location, fixture complexity, and labor rates.
- Basic kitchen or bathroom faucet: $150–$225
- Pull-down kitchen faucet with sprayer: $225–$300
- Wall-mounted or specialty faucet: $300–$450+
⚠️ Note: Some plumbers charge a “customer-supplied fixture fee” of $25–$75 to cover liability and extra handling. Always ask for a written quote that includes this detail.
According to Angi (formerly Angie’s List), homeowners who supplied their own faucet saved an average of $85 compared to those who used the plumber’s inventory—but 12% had to pay for a second visit due to fit issues.
Step-by-Step: What Happens During a Professional Faucet Installation
If you’ve hired a plumber to install your purchased faucet, here’s what to expect:
- Pre-Installation Inspection
The plumber will shut off water supply valves (usually under the sink), drain residual water, and inspect your existing pipes, shutoff valves, and sink deck.
- Remove Old Faucet
Using basin wrenches and adjustable pliers, they’ll disconnect supply lines and remove mounting nuts. Old caulk or putty is cleaned thoroughly. - Prepare for New Installation
If needed, they’ll install new supply lines (recommended for fixtures over 5 years old). They may also replace worn shutoff valves—a smart $30–$60 upgrade that prevents future leaks. - Mount New Faucet
The new faucet is inserted through the sink holes, secured with mounting hardware, and connected to supply lines. Teflon tape is used on threaded connections to prevent leaks. - Test for Leaks & Function
Water is turned back on slowly. The plumber checks for drips at connections and ensures hot/cold flow correctly. They’ll also verify sprayer function (if applicable). - Clean Up & Walkthrough
Tools are removed, debris is cleaned, and the plumber shows you how to operate your new faucet.
Most installations take 1–2 hours for standard models. Complex setups (e.g., adding a soap dispenser or switching from 3-hole to single-hole) may take longer.
What to Ask Your Plumber Before Hiring
To ensure a smooth experience, ask these 5 questions:
- “Do you install customer-supplied faucets?”
- “Is there an extra fee for using my faucet?”
- “Will you inspect my shutoff valves and supply lines?”
- “What’s your labor warranty?” (Most offer 30–90 days)
- “Can you provide a written estimate before starting?”
A trustworthy plumber will welcome these questions—and answer them clearly.
FAQ Section
Q: Will a plumber install any faucet I buy online?
A: Most will, but they may refuse if the faucet is extremely cheap, non-UL-listed, or lacks proper certification. Stick to reputable brands sold by authorized retailers (e.g., Home Depot, Ferguson, or the manufacturer’s website).
Q: Can I return the faucet if the plumber says it won’t fit?
A: It depends on the retailer’s return policy. Big-box stores like Lowe’s or Home Depot usually allow returns within 90 days with a receipt—even if opened—as long as it’s not damaged. Always keep packaging until installation is complete.
Q: Should I buy a faucet with a lifetime warranty?
A: Yes! Brands like Delta and Moen offer limited lifetime warranties on finish and function for the original owner. This covers defects—not installation errors—so proper installation is key.
Q: How long does a faucet installation take?
A: Typically 60–90 minutes for a standard replacement. Allow 2–3 hours if valves or pipes need upgrading.
Q: Can I install it myself to save money?
A: If you’re handy and have basic tools (basin wrench, adjustable pliers, Teflon tape), DIY is possible. But if you damage pipes or cause a leak, repair costs can exceed $300. When in doubt, hire a pro.
Q: Does the plumber need to be licensed?
A: Yes. Always hire a licensed, insured plumber. Unlicensed handymen may void your home insurance if a leak causes water damage. Verify license status via your state’s contractor board.
Conclusion
So, will a plumber install a faucet you bought? Absolutely—most will, and many appreciate your initiative! By choosing your own fixture, you gain control over style, features, and upfront cost. Just be sure to:
✅ Confirm compatibility with your sink
