Garbage Disposal Cost by Motor Size
The motor size of garbage disposal determines how much food waste it can process at once. Larger, more powerful motors come with a higher price tag, so it’s essential to select the appropriate motor size for your household to avoid spending more than necessary.

Larger households of five to eight people will need a 1-horsepower motor, typically priced between $240 and $440.

Labor Cost to Replace a Garbage Disposal
Replacing an old garbage disposal is generally a simple job that should take about an hour for an SD Appliance Repair technician to complete. Installation typically costs $90 to $140 per hour. The process involves leveling the unit, making a few basic connections, securing the exterior, and testing it. Most professionals will include the removal of the old disposal in their quote, as they’re already dismantling it to install the new one. They’re also familiar with local disposal centers for faulty units. However, if there are issues like a rusted or hard-to-remove disposal, additional charges of $90 to $140 may apply to cover the extra time needed for removal.
Additional Garbage Disposal Replacement Cost Factors
The cost of replacing garbage disposal typically ranges from $240 to $665, with an average of around $590. If you’re experienced with DIY projects, you might spend as little as $115 for a new unit and the necessary tools for installation. Prices vary depending on the unit’s type, motor size, and labor fees.
Feed Type
In the realm of garbage disposals, there are two main types to consider: continuous feed and batch feed. Continuous feed models typically range from $115 to $1,040, while batch feed models are priced between $115 and $340. Continuous feed units are usually more expensive because they allow for ongoing operation without having to pause or cover the unit. On the other hand, batch feed disposals are better suited for homes with children, as the cover prevents accidental activation.

Material
Garbage disposals are typically made from either aluminum or stainless steel. Aluminum units are more affordable and commonly used, ranging from $115 to $340 depending on size and power. However, aluminum disposals are more susceptible to leaks and rust, with a lifespan typically under 10 years. Stainless steel disposals, priced between $440 and $1,140, are more durable and resistant to corrosion and leaks. These models are often preferred in busy households and commercial settings due to their strength and longevity.
Warranties
When you purchase a new garbage disposal, it typically includes a manufacturer’s warranty, and sometimes an additional one from the installer. Be sure to review the details when buying or hiring a plumber to understand what is covered. Warranties can last anywhere from one to ten years, depending on the brand and model. These are limited warranties that cover defects in materials or workmanship, but you’ll still need to use the disposal carefully to avoid costly issues.
Electrical Upgrades
The electrical requirements for your garbage disposal vary based on its model and local building regulations. Some units can be easily plugged into a standard 120-volt outlet and use five to ten amps, while other codes may call for a dedicated 15-amp circuit with GFCI (ground fault circuit interrupter) and AFCI (arc fault circuit interrupter) protection. These safety features ensure the breaker will trip if necessary to prevent hazards. If you’re unsure about the electrical needs for your disposal or need new wiring, it’s best to consult a licensed electrician.
