How Much Does It Cost to Replace a Garbage Disposal in 2026?
The average cost to replace a garbage disposal is $200 to $500 installed. Here is what plumbers charge, the best disposals for the money, and how to install one yourself in under an hour.
Garbage disposals are one of the most replaceable appliances in a kitchen. The average cost to have one professionally installed runs $200 to $500, but this is also one of the most achievable DIY plumbing projects for a homeowner with basic skills.
Average Cost to Replace a Garbage Disposal in 2026
| Unit Type | Unit Cost | Installed Total |
|---|---|---|
| Basic (1/3 HP) | $70 to $120 | $200 to $320 |
| Mid-range (1/2 HP) | $120 to $200 | $270 to $420 |
| Premium (3/4 HP) | $180 to $300 | $330 to $550 |

The Best Disposal for Most Homes
For most households the sweet spot is a quality 1/2 HP unit. The InSinkErator disposal is the most trusted brand in the category for good reason. It handles everyday food waste reliably, runs quietly compared to budget units, and backs its products with strong warranties. InSinkErator units also use a standard mounting assembly that fits most existing sink setups, making replacement straightforward.
What You Are Actually Paying For
The unit itself costs $70 to $400 depending on motor size. Labor to remove the old unit and install the new one typically runs $100 to $200 for a plumber and takes about 30 to 45 minutes.
Two Tools Every DIYer Needs
When a disposal jams and stops working, the first fix to try is the disposal wrench key. This small hex wrench inserts into the hole on the bottom of the unit and manually rotates the grinding plate to free whatever is causing the jam. This tool fixes a surprising number of disposal failures for free in under two minutes. Most disposals ship with one, but they get lost easily and are worth having a spare.
When installing a new disposal, plumber's putty creates the watertight seal between the drain flange and the sink basin. Apply it under the flange before pressing it into the drain hole for a leak-free installation that lasts.
Should You DIY It?
Yes, if you are replacing an existing disposal. If the mounting assembly is already in place, swapping a disposal is a 30 to 45 minute job that requires no special tools beyond the wrench key and a screwdriver.
The basic steps are: disconnect power at the breaker, disconnect the drain line, twist and remove the old unit from the mount, attach the new unit, reconnect the drain, restore power, and test.
Verdict: Strong DIY candidate for a straight replacement. Save $100 to $200 in labor.
Signs Your Disposal Needs Replacing vs Repairing
Replace it when: it leaks from the bottom (internal seal failure), the motor hums but does not spin (burned out motor), or it is over 10 years old with repeated problems.
Repair it first when: it will not turn on at all (press the red reset button on the bottom first), or it is jammed (use the hex wrench key on the bottom).
Always try the reset button and manual unjam before assuming the unit needs replacement. These two steps fix the majority of disposal problems for free.
Bottom Line
Budget $250 to $400 for a quality mid-range disposal professionally installed. If you DIY it, you are looking at $120 to $200 for the unit plus 45 minutes of your time. Either way this is one of the more affordable and straightforward kitchen repairs you will face.
