How Much Does Garbage Disposal Installation Cost?
Estimate garbage disposal purchase and installation cost — with the free calculator and what affects the price.
A garbage disposal grinds food waste and keeps your kitchen drain clear. The price depends on the unit's horsepower, brand and labor. This guide covers the installed cost and a calculator.
THE SHORT ANSWER
The short answer
Garbage disposal installation runs $200–$625 total; the unit itself costs $80–$500. Labor runs $50–$100 per hour. Direct replacement on an existing mount is the cheapest install — most projects total $250–$500.
Disposal types and prices
Budget units (1/3 HP) run $80-$150 and handle light use. Standard units (1/2 HP) cost $150-$250 and suit most kitchens. Premium models (3/4-1 HP) run $250-$500, grind faster and are quieter. Labor adds $150-$300.
- Budget (1/3 HP): $80–$150
- Standard (1/2 HP): $150–$250
- Premium (3/4-1 HP): $250–$500
- Installation labor: $150–$300
What affects labor cost
Direct replacement on an existing mount is cheapest at $150-$200. Adding a new circuit or outlet costs $200-$400 more. If there's no disposal at all, the sink drain and under-sink plumbing may need changes.
Do I need both trades?
Wiring the switch is electrical work; mounting and drain connection is plumbing. Many plumbers handle both in one visit. Confirm the quote includes the outlet/switch, not just the unit.
