How Much Does a Garbage Disposal Cost?

Of all the home improvement projects you can take on, nobody gives a second thought to replacing or upgrading the garbage disposal. Many people won't think about it until it's too late and they are left with a nightmare in the sink.

When it comes to garbage disposals, you get what you pay for. Although you may see a broad range of prices, keep in mind that each price point coincides with different levels of performance and other optional features. Here are a few things to consider when choosing a garbage disposal.

Horsepower:  Your garbage disposal's horsepower will account for most of the difference in price.

Continuous vs. Batch Fed:  Continuous fed garbage disposals are generally cheaper and more popular than batch fed disposals. A continuous fed disposal is one in which you manually turn on and off. Batch fed disposals will operate when a certain level of waste has entered the receptacle.

Waste Disposal Methods:  Garbage disposals are also designed depending on your waste disposal method. City sewage doesn't require food waste to be as finely ground up as you would need for a septic tank. Therefore, you will have various disposals for each method, and garbage disposals designed for septic tanks will generally be more expensive.

Other Features:  There are other features to consider on your garbage disposal such as noise reduction, receptacle capacity, reverse modes designed to clear up jams and stainless steel chambers.

Price Ranges

The cost of your waste disposal will depend on these features. Here is a general idea of what to expect when comparing prices.


These garbage disposals tend to be 1/3 to 1/2 horsepower and are continuous fed disposals designed for city sewage. They usually don't have noise reduction features or come with a reverse mode. Their low power cannot handle much food waste at one time without jamming up. Usually, these disposals will come with a one year warranty.

My Budget Pick:

These disposals will be 1/2 to 3/4 horsepower. They will have a bigger receptacle to handle larger jobs and will grind up food waste into smaller pieces. Most models in this price range will still be continuous fed models but may have other features such as noise reduction and a reverse mode and stainless steel grinding chambers.

Also, many models in this range are the batch fed models and will work automatically without you having to turn them on and off. The power also ranges from 3/4 to 1 horsepower. These garbage disposals will come with extended warranties with some even having lifetime warranties.

If you are still unsure about which garbage disposal is right for you then be sure to ask your local hardware stores for help.

They also know which models are the most popular and most reliable and which garbage disposals will be the better value for your needs. Also, it never hurts to do some internet research or check with your friends and neighbors to find out which models are the most reliable.
