Replacing or installing a new sink and faucet might seem like a weekend DIY project—until you’re knee-deep in leaks, mismatched fittings, or worse, water damage. If you’re asking, “How much is a plumber to install sink and faucet?”, you’re not alone. Homeowners across the U.S. face this exact question every year, especially during kitchen or bathroom renovations. The good news? Hiring a licensed plumber ensures the job is done right the first time—saving you time, stress, and costly repairs down the road.
What’s the Average Cost to Hire a Plumber for Sink and Faucet Installation?
According to HomeAdvisor’s 2025 True Cost Report, the average cost to install a sink and faucet ranges from $220 to $550, with most homeowners paying around $370. This includes labor, basic materials, and minor adjustments like reconnecting supply lines or mounting hardware.
However, prices can swing dramatically based on:
- Type of sink (drop-in, undermount, farmhouse)
- Faucet complexity (single-handle vs. smart touchless models)
- Existing plumbing condition
- Geographic location (urban vs. rural rates)
💡 Pro Tip: Labor typically accounts for 60–70% of the total cost. In high-cost areas like New York City or San Francisco, hourly rates can exceed $120/hour, compared to $60–$85 in the Midwest.
What Factors Affect the Total Installation Cost?
Understanding what drives pricing helps you budget wisely and avoid surprise fees. Here are the top cost influencers:
1. Type of Sink
| Sink Type | Avg. Installation Cost | Notes |
|---|---|---|
| Drop-in (top-mount) | $150–$300 | Easiest to install; minimal plumbing changes |
| Undermount | $250–$450 | Requires precise countertop cutouts and strong support |
| Farmhouse (apron-front) | $300–$600+ | Heavy; may need cabinet reinforcement |
2. Faucet Features
Basic single-handle faucets cost less to install than:
- Pull-down sprayers
- Touchless or smart faucets (may require electrical work)
- Wall-mounted models (need rerouting of pipes)
3. Plumbing Modifications
If your existing setup needs upgrades—like replacing old shutoff valves, adding a garbage disposal, or rerouting drain lines—expect $100–$300 extra.
4. Location & Accessibility
Installing a sink in a finished basement or tight powder room costs more due to limited workspace. Conversely, open-concept kitchens often allow faster, cheaper installs.

DIY vs. Hiring a Pro: Which Saves More?
Many homeowners consider DIY to cut costs—but is it worth the risk?
✅ DIY Pros:
- Save $150–$300 on labor
- Full control over timeline
- Sense of accomplishment
❌ DIY Cons:
- Risk of leaks, flooding, or code violations
- Voided appliance warranties (some brands require pro installation)
- Time-consuming troubleshooting (average DIYer spends 4–8 hours)
📊 Stat Alert: A 2024 Angi survey found that 32% of DIY plumbing attempts required a professional fix within 6 months—costing users 2x more than hiring upfront.
Unless you’re experienced with pipe threading, P-traps, and water pressure testing, hiring a licensed plumber is the smarter long-term investment.
Step-by-Step: What Happens During Professional Installation?
Curious what you’re paying for? Here’s exactly how a pro handles your sink and faucet install:
- Shut Off Water Supply
Turn off hot/cold valves under the sink. Open faucet to drain residual water. - Remove Old Fixture
Disconnect supply lines, loosen mounting clips, and carefully lift out the old sink. - Inspect & Prep Area
Check for mold, rot, or corroded pipes. Replace damaged components if needed. - Install New Sink
- For drop-in: Apply silicone sealant, set sink, tighten clips from below.
- For undermount: Use epoxy brackets and secure from beneath the counter.
- Mount Faucet
Insert through pre-drilled holes, attach mounting nuts, connect supply lines (use Teflon tape on threads). - Reconnect Drain & Test
Reattach P-trap, turn water back on, and check for leaks at 20–30 PSI (standard home pressure). - Final Cleanup & Demo
Wipe surfaces, dispose of old parts, and show you how to operate new features.
Most jobs take 2–4 hours when no complications arise.
How to Save Money Without Sacrificing Quality
You don’t need to overspend. Try these vetted strategies:
- Bundle Services: Need a disposal installed too? Ask for a package rate.
- Buy Fixtures Yourself: Plumbers often mark up materials by 20–30%. Purchase your own sink/faucet from retailers like Home Depot or Ferguson.
- Schedule Off-Peak: Avoid weekends or holidays—many pros offer 10–15% weekday discounts.
- Get 3 Quotes: Compare not just price, but warranty terms and licensing status.
🔍 Always verify: Your plumber should have a valid state license, liability insurance, and at least 2 years of local experience.
