If you’ve ever had a kitchen sink clogged, you know why having a good disposal is a smart idea.

Residents of high density apartment buildings love them for good reason — they’re the only way to ensure the plumbing doesn’t get backed up in a block of toilets, sinks and showers. It’s the biggest, smelliest problem a building can have.

If you have children, you know that disaster can strike at any moment. If you toss diapers into your toilet, you know exactly what I’m talking about.

When it’s not Spring Break in your bathroom, you don’t have to suffer through that nightmare.

A disposal is the only way to get rid of that gunk without having to temporarily connect the sink to your bathtub.

And, if you’re living in a tiny home without a laundry machine, a disposal is a great way to handle those kitchen scraps.

The reality is, most of us don’t have the bedroom space to have a dedicated garbage. If you don’t, check this article about thirteen ways to hide a small garbage bin in your kitchen.

But, that smell is the biggest problem in tiny home kitchens.

The Badger 5 Series can break down food scraps somewhat better than the Badger 1 Series, but the difference isn’t major. The Badger 5 grinds more quietly than other disposals on our list and doesn’t vibrate as much, but it’s not as powerful as some and can’t grind large bones.

Frequently Asked Questions (FAQ)

What is the best garbage disposal for the money?

We've tried to focus on the best models, rather than just the cheapest models. While price is important, features, value, and performance are just as important when choosing a good model.

Garbage disposals can be used to grind up almost any food waste that ends up in your kitchen sink, so it's a great alternative to sending that food down the drain and causing a clog. But there's more to a garbage disposal than just grinding food, so the best models also have additional features like easy switch access, continuous feed, and grinding batches. While these features are not designed to get food more thoroughly chopped, they are used to make using the disposer more convenient.

How do I know which garbage disposal to buy?

Garbage disposals for home kitchens can be found in a number of different capacities. Typically, home size garbage disposals will come in one, or at the maximum, two horsepower capacity. We recommend that you stick with one horsepower. Anything more than two horsepower is overkill for a home kitchen. Plus, the larger models typically require more space under your sink before you can install them.

You'll also want to look for a garbage disposal with a reversed water flow. This feature works great for getting stubborn grease, food, or other debris off of the blades and helps keep your disposal last longer. Most garbage disposal units come with this feature built-in, but some of the cheaper models do not.

As for features, a lot of garbage disposals will come with a quiet button which switches the sound output from a loud humming sound to a quiet grinding sound. We recommend that you stay away from units with this feature as they often don't last very long.

Why is my garbage disposal leaking under the sink?

Any time you have a leak under a sink cabinet, you have a problem. The purpose of cabinets is to keep water from getting into their contents. This is doubly true when you have cabinets underneath the kitchen sink. This is why virtually all garbage disposals have splash guards built into them; it's to prevent the very problem you're dealing with. So before you panic, make sure the hole in your splash guard is plugged, otherwise you're going to end up with pretty much the same thing as if you had no splash guard at all.

Does your garbage disposal make a loud or unusual noise?

If your disposal is making an unusual rattling sound make sure that the sink stopper plug is sitting on top of the sink drain, not lodged somewhere down in the drain. Next, check the drain to make sure there are no large hard scraps around the drain grinding against the trap. These can clog up the drain and cause a lot of rattling.

Do garbage disposals fit all sinks?

Garbage disposals might not be the most glamorous features in your kitchen, but they are extremely handy to have and certainly worthwhile additions to your sink. By removing food waste, you are also clearing out space in your cabinets and refrigerator. Plus, your family can avoid another smelly trip to the dumpster.

However, just any garbage disposal isn’t always the best option for your sink. It’s important to ensure that the mounting plate for your unit will fit properly into your sink drain. If you have an unusually shaped sink (such as a large, deep sink), then you may want to consider a specially designed sink disposal instead.


If you’ve ever tried to scrounge through the clutter underneath your sink, you’ve no doubt felt the frustration in trying to locate a simple item like a wrench. One thing that will help is to more clearly label what’s in each basket. I don’t have a large family, but there are times when I wish I did, just so I could burn off energy using the dishwasher! Because there are so many dishes to wash, you want to work carefully and quickly to keep the process moving along.
