How Much Does Garbage Disposal Installation Cost?
Garbage Disposal installation cost depends on one thing: whether your kitchen already has the plumbing and electrical in place.
- DIY with a corded disposal (existing outlet): $70–$200 (unit cost only)
- Simple replacement (matching mount, existing outlet): $190–$380
- Modified replacement (drain adjustments needed): $280–$580
- First-time installation (new electrical + plumbing): $750–$1,400+
This guide shows you exactly what you’ll pay, what drives costs up or down, and how to avoid the expensive surprises that catch most people off guard.
Average Garbage Disposal Installation Cost Breakdown
| Cost Category | Simple Replacement | First-Time Install |
|---|---|---|
| Disposal Unit | $70–$500 | $70–$500 |
| Plumber Labor (1–2 hrs) | $80–$200 | $300–$600 |
| Electrician (New Circuit) | Not needed | $570–$1,000 |
| GFCI Outlet Upgrade | Not needed | $75–$150 |
| Switch Installation | Not needed | $50–$200 |
| Total | $190–$580 | $750–$1,400+ |
The electrical work is what makes first-time installations expensive. If your kitchen already has a GFCI outlet under the sink, you skip $700-$1,300 in electrical costs.
What Affects Garbage Disposal Installation Cost?
2 main factors determine what you’ll actually pay. Understanding these helps you budget accurately and avoid sticker shock.
1. Disposal Unit Costs by HP
| HP | Best For | Unit Price | Examples |
|---|---|---|---|
| 1/3 HP | 1–2 people, light use | $45–$120 | Waste King L-111, Badger 1 |
| 1/2 HP | 2–3 people, regular cooking | $80–$150 | Waste King L-2600, Badger 5 |
| 3/4 HP | 3–5 people, daily cooking | $120–$250 | Moen EX75C, Evolution Compact |
| 1 HP | 4+ people, heavy use | $100–$400+ | Waste King L-8000, Evolution Advanced |
2. Labor Costs by Region
| Area | Plumber Hourly Rate | Typical Total Install |
|---|---|---|
| Metro (NYC, SF, Seattle) | $150–$200/hr | 30–50% above average |
| Mid-size (Chicago, Dallas, Denver) | $80–$130/hr | Near national average |
| Small towns / rural | $60–$90/hr | 20–30% below average |
How to Save Money on Garbage Disposal Installation
- DIY the replacement — If you have an existing outlet and matching mount type, install it yourself and save $100-$400 in labor. Models with pre-installed power cords and EZ Mount (most Waste King models) install in 15-30 minutes. See our installation guide.
- Buy mid-range — The jump from $50 to $120 buys stainless steel components, longer warranties, and quieter operation. Budget models need replacing sooner, costing more long-term.
- Schedule weekday appointments — Weekend and emergency rates run 1.5x to 2x normal pricing.
- Bundle with other plumbing work — Adding disposal installation to an existing plumbing visit saves on trip charges.
- Shop sales — Home Depot, Lowe’s, and Amazon discount disposals of $50-$100 during Black Friday, Memorial Day, and Labor Day.
Conclusion
For most homeowners, replacing an existing disposal costs $190-$580, including the unit and labor. DIY replacement with a corded disposal costs just $70-$200. First-time installations jump to $750-$1,400+ due to electrical work. The best value: a mid-range 3/4 HP disposal ($120-$250) with professional installation, lasting 10+ years.
