Upgrading your kitchen with a new faucet or garbage disposal can boost both functionality and value—but how much will it actually cost to have a plumber do the job? If you’re asking, “What’s the cost to have plumber install kitchen faucet and garbage disposal?”, you’re not alone. Many U.S. homeowners face this exact question when planning kitchen updates or repairs. The good news? With the right information, you can avoid surprise bills and make smart, budget-friendly choices.
What’s the Average Cost to Install a Kitchen Faucet and Garbage Disposal?
On average, U.S. homeowners pay between $400 and $1,200 to have a licensed plumber install both a kitchen faucet and a garbage disposal. However, the final price depends heavily on several factors—your location, the complexity of the job, and whether you’re replacing existing fixtures or starting from scratch.
According to HomeAdvisor’s 2024 data:
- Faucet-only installation: $150–$350
- Garbage disposal-only installation: $200–$500
- Combined installation: $400–$1,200
“Most homeowners underestimate labor costs,” says Maria Lopez, a master plumber with over 15 years of experience in Chicago. “If your sink isn’t pre-plumbed for a disposal or you need new shutoff valves, that adds time—and money.”
What Factors Affect Installation Costs?
1. Type of Faucet and Disposal Unit
- Faucets: Basic models start at $50, while premium touchless or pull-down faucets can exceed $300. Higher-end models often require additional mounting hardware or electrical work (for sensor faucets).
- Garbage Disposals: Standard ½ HP units cost $75–$150; heavy-duty 1 HP models range from $150–$300. Some require new electrical outlets or hardwiring.
2. Existing Plumbing Setup
If your kitchen already has:
- A dishwasher air gap
- A disposal-ready drain
- Accessible shutoff valves
…installation will be faster and cheaper. But if you need new pipes, electrical outlets, or cabinet modifications, expect to pay 20–40% more.
3. Labor Rates by Region
Plumbers in rural areas may charge $45–$75/hour, while major cities like New York or San Francisco often see $100–$150/hour. Most installations take 2–4 hours, so labor alone can range from $100 to $600.
4. Permits and Inspections
In some municipalities (e.g., parts of California or Florida), installing a garbage disposal may require a minor plumbing permit ($25–$100). Always check local codes—your plumber should handle this, but it adds to the timeline and cost.
Step-by-Step: What Happens During Installation?
Faucet Installation (Typical Process)
- Shut off water supply under the sink (or main valve if no shutoffs exist).
- Remove old faucet—usually secured with mounting nuts or clips.
- Clean sink surface and install new gasket or sealant.
- Mount new faucet, connect supply lines (use Teflon tape on threads).
- Turn water back on, check for leaks, and test spray function (if applicable).
⏱️ Time required: 45–90 minutes for standard models.
Garbage Disposal Installation
- Disconnect dishwasher drain (if connected).
- Remove old disposal or prepare drain for first-time install.
- Mount new disposal using the mounting assembly (most use a 3-bolt flange system).
- Connect to drain pipe and dishwasher hose (if applicable).
- Wire the unit—either plug-in (requires GFCI outlet) or hardwired (requires electrician in some states).
- Test operation with water running to ensure proper drainage and no vibrations.
⚠️ Safety note: Always verify local electrical codes. In some states (e.g., Massachusetts), only licensed electricians can make hardwired connections.

Cost Comparison: DIY vs. Hiring a Pro
| Factor | DIY | Professional Plumber |
|---|---|---|
| Cost | $100–$400 (parts only) | $400–$1,200 (parts + labor) |
| Time | 3–6 hours (plus learning curve) | 2–4 hours |
| Tools Needed | Basin wrench, plumber’s putty, wire nuts, etc. | Provided by plumber |
| Risk of Leaks | Moderate to high (if inexperienced) | Very low (licensed pros offer warranties) |
| Warranty | None (unless parts covered) | Often 1-year labor warranty |
Verdict: If you’re comfortable with basic plumbing and your setup is straightforward, DIY can save money. But if you lack tools, time, or confidence—or if electrical work is involved—hiring a pro is safer and often more cost-effective long-term.
How to Save Money Without Sacrificing Quality
- Bundle services: Ask if your plumber offers discounts for installing both fixtures at once.
- Buy your own fixtures: Retailers like Home Depot or Lowe’s often have better prices than contractor markups.
- Schedule off-peak: Avoid weekends or holidays when emergency rates apply.
- Get 3 quotes: Use platforms like Angi, Thumbtack, or local referrals to compare fair pricing.
- Check for rebates: Some utility companies offer rebates for energy-efficient disposals (e.g., InSinkErator Evolution models).
FAQ Section
Q1: Does installing a garbage disposal require an electrician?
A: It depends. If you have a GFCI outlet under the sink, most plumbers can plug it in. But if you need new wiring or a dedicated circuit, many states require a licensed electrician. Always confirm local regulations.
Q2: Can a plumber install a faucet and disposal on the same day?
A: Yes—most combined jobs are completed in one visit (2–4 hours). Just ensure the fixtures are on-site before the plumber arrives.
Q3: How long do kitchen faucets and disposals last?
A:
- Faucets: 10–15 years (with ceramic disc valves)
- Garbage disposals: 8–12 years (with proper use and maintenance)
Regular cleaning and avoiding grease or fibrous foods can extend disposal life.
Q4: What’s included in a typical installation quote?
A: Most quotes include:
- Removal and disposal of old units
- Installation of new faucet and disposal
- Connection to water, drain, and power
- Basic leak and function testing
Always ask if parts, permits, or disposal fees are extra.
Q5: Will my homeowner’s insurance cover installation errors?
A: No—insurance covers damage (like a burst pipe), not faulty workmanship. That’s why hiring a licensed, insured plumber with a labor warranty is critical.
Q6: Can I install a disposal if I have a septic system?
A: Yes, but use a septic-safe model (e.g., InSinkErator Septic Assist) and limit usage. According to the EPA, moderate disposal use doesn’t harm well-maintained septic tanks—but always consult your septic provider first.
