Kitchen Garbage Disposal Buying Guide

There are two types of kitchen garbage disposals: batch-feed and continuous feed garbage disposals. Let’s take a look at each feed type, and see which one is ideal for your home.

With batch-feed garbage disposals, you have to put a batch of food scraps into a chamber, turn the cold water on, and put a magnetic stopper in place to activate the grinder. This type of garbage disposal is ideal for homeowners who don’t want the hassle of adding an electrical switch near the sink or if it’s impossible to modify the electrical setup in your sink. The only downside is that batch-feed garbage disposals are pricier than their continuous-feed counterparts.

Now, let’s take a look at continuous-feed models. With this type of garbage disposal, you have to activate the grinder first, push the food scraps into the chamber, and run the cold water to help the garbage disposal grind the scraps. These units are often more affordable than batch-feed models.

These garbage disposals, however, need to be attached to a wall or sink-top switch and power outlet. Installation can be a bit of a challenge, especially if you’re new to the world of DIYing.

Garbage Disposal Motor Size

A garbage disposal’s motor size is measured in horsepower, and it is the most crucial factor when it comes to shopping for the best garbage disposal for your home. Let’s take a look at the different motor sizes available, starting from the highest to the lowest.

  • 1 HP and Beyond

If you cook multiple times every day or you have a lot of food scraps to process, then it’s best to get a sink garbage disposal that is powered by a 1 HP motor. Built for busy kitchens, the chambers and impellers of these garbage disposals are made of corrosion-resistant stainless steel. Their chambers are considerably larger, allowing the user to process more food scraps than is usual. 

Garbage disposals with 1 HP motors are pricier, so get ready to spend upwards of $120. They can get quite bulky, too, so make sure that there’s sufficient room under your kitchen sink before installation.

  • 3/4 HP

If your household comprises 2 to 4 people or you have a large family but you cook only occasionally during the week, then a garbage disposal with a 3/4 HP motor is ideal for your home. The unit’s chamber is large enough to process a lot of the food scraps that a mid-sized household produces. 

The chamber and the impeller are typically made of rugged stainless steel, and they operate more smoothly and quietly than their 1/2 HP and 1/3 HP counterparts. But make sure that you have a lot of space underneath your kitchen sink as these are relatively large garbage disposals. Plus, they can be a bit more expensive because of their solid steel construction and high-quality parts.  

  • 1/2 HP

Garbage disposals with 1/2 HP motors are ideal for most homes in the country. They can pulverize soft foods, fruit peels, fish bones, cooked meat, and other smaller, softer leftovers. They can also grind vegetable scraps, but make sure not to overdo them to prevent jams.

They are more affordable, and their price point makes them ideal for smaller households. But they can be noisier than 3/4 HP and 1 HP garbage disposals. If you must get a 1/2 HP garbage disposal, then it’s best to get one with stainless steel components to ensure that it will last a long time.

  • 1/3 HP

Garbage disposals with 1/3 HP are ideal for smaller households. Their components are cheaper, and this makes them the most affordable options in the market. If you’re rarely going to use the garbage disposal, then this might be the best option for you.

Other Factors to Consider When Buying a Kitchen Garbage Disposal


Garbage disposals can be pretty loud and distracting. If you’re bothered by the noise, then check if the unit you’re planning to buy comes with noise and vibration-muffling features. These include rubber sound baffles, insulated mounting baffles, and more.

Internal components

Look for garbage disposals with impellers, grind chambers, and other internal components that are made of stainless steel. Stainless steel resists corrosion better than other types of metal, thereby prolonging the life of your garbage disposal.

Power Cord

Most sink garbage disposals already have a power cord pre-installed. All you need to do is mount the unit, plug the power cord into an outlet, and you’re good to go. 

Some units, on the other hand, do not include a power cord. If that’s the case, you can purchase a separate power cord or reuse an old but compatible power cord from an old unit. 

Ease of Installation

Look for garbage disposal with standard EZ-Mount or Quick-mount features for easier installation.
