Garbage disposal replacement cost in 2026

Garbage disposal replacement is one of the clearest DIY-savings jobs in the kitchen. Here's the full cost breakdown.

What you're paying for

Component	Typical range	Notes
½ HP disposal (InSinkErator Badger 5)	$100–$140	Entry-level, 1–2 person household
¾ HP disposal (InSinkErator Evolution Compact)	$160–$220	Best value for family kitchens
1 HP premium (InSinkErator Evolution Excel)	$250–$320	Septic systems / heavy use
Labor	$120–$220	45-minute job, often at 2-hour minimum
Plumber's putty / silicone	$5–$10	Always replaced
Haul-away	$0–$50	Usually included

Typical all-in prices

Scenario	½ HP	¾ HP	1 HP premium
DIY, you supply everything	$85–$150	$160–$230	$250–$330
Hired, you supply disposal	$230–$340	$290–$420	$380–$530
Hired, plumber supplies disposal	$280–$400	$350–$500	$450–$600

Plumber-supplied adds 20–30% markup over retail. For a $150 ½ HP unit, that's $30–$45 extra. Not huge, but real.

Regional variation

Region	Standard install (hired)	Median
Northeast	$280–$480	$380
West Coast	$260–$450	$350
Midwest	$220–$380	$300
South	$200–$350	$280

Published-source medians. Individual metro variation can be larger.

What you shouldn't pay more than

$500+ for a like-for-like disposal replacement without specific issues is overpriced. The job is 45 minutes of work.

$230–$400 is fair for a like-for-like hired install with a mid-range disposal. $500+ needs specific justification: new mounting ring for a different brand, plumbing rework around the sink, converting from hardwired to plug-in or vice versa. $600+ is almost always overpriced unless the installer is also replacing the sink drain, P-trap, or air gap.

Red flags:

• Separate "electrical fee" for what is a 10-minute wire-nut connection.
• Separate "disposal-specialty tools" fee — there are none.
• "Haul-away fee" as a separate line item (should be bundled).
• "Emergency rate" on a scheduled appointment.

When the quote is legitimately higher

Converting from hardwired to plug-in — requires a new outlet installation (electrician territory). Add $150–$400 for the electrical work if a dedicated outlet doesn't exist.

Replacing the dishwasher-drain tie-in — if the disposal drain routing is complicated (e.g., the old unit had a non-standard Y-fitting that needs updating). Add $50–$150.

Upgrading the mounting ring — if your old unit uses a non-InSinkErator mount and the new unit requires a different ring, that's included with most new units but adds 15 minutes of labor. Usually not a separate charge.

DIY math

A ½ HP InSinkErator Badger 5 from Home Depot: $125. Plumber's putty: $6. Total DIY cost: $131. Time: 60–75 minutes including trips to the garage for tools.

Hired install with the same unit: $280–$340. DIY savings: $150–$210 on an hour of work.

This is one of the highest-savings DIY jobs in the kitchen. See the DIY or Hire verdict and repair vs replace guide.

Choosing a disposal

For most US households, the sweet spot is ¾ HP. Quieter than ½ HP, handles more food waste, lasts longer. Best value brands:

• InSinkErator Evolution Compact (~$180): most recommended, largest service network, best warranty.
• Moen GX75C (~$200): comparable quality, slightly quieter.
• Waste King L-8000 (~$165): better value per HP, slightly louder.

Skip:

• Off-brand disposals under $100. Short motor life.
• 1/3 HP units. Struggle with normal use, fail fast.
• "Quiet" marketing claims that aren't backed by dB ratings. Every manufacturer claims "quiet operation."

Important compatibility note

Modern InSinkErator, Moen, Waste King, and most major brands use the same three-bolt mounting ring. If your existing disposal is one of these, the new unit can mount to the existing ring in many cases. If you're switching brands and the mounting ring doesn't match, most new units include a compatible ring in the box.

The one exception: very old (20+ years) installations with proprietary mounting hardware. In that rare case, you might need to buy a mount-adapter kit separately ($15–$25).
