What is the most powerful garbage disposal you can buy?

If you have ever filled up a kitchen sink so full of coffee grinds, egg shells, turkey bones, and greasy cheese that the drain clogged, you’ll know why garbage disposals were invented.

A garbage disposal is one of the most convenient, most under used plumbing appliances in your kitchen.

Garbage disposals are insanely convenient, and are usually operated with one push of a switch. Almost any food you can think of can go down the disposal, from vegetables and animal bones, to pasta and rice, to ice cream, leftover pizza, and even uncooked chicken parts.

As your food waste enters the garbage disposal it is guided by blades and rapidly ground into tiny particles. All this happens in between the pipes as your water is directed away through the drain.

The water from the faucet pushes your waste down the pipes and you are left with perfectly ground food waste, and a clean drain. As long as you take care to sweep food scraps from your sink into the garbage disposal, instead of letting it sit in your sink, you’ll never have to worry about clogged drains again.

Here are the most powerful and best commercial kitchen disposals you can buy.

Frequently Asked Questions (FAQ)

How do I know which garbage disposal to buy?

Garbage disposals are about as varied as the names they come with. They range from strong, powerful, and robust machines that effortlessly grind anything you throw at them to inefficient, weak, and relatively small disposals that run cheaply but can’t really crush down the more fibrous contents of your kitchen.

Easy-to-use and hardy disposals aren’t always the best in terms of quality either. While easy to set up and operate, often times they won’t tackle the more awkward items like corncobs or chicken, particularly if you live in a place that’s a little more metropolitan.

This means your garbage disposal is a very important investment and you should take your time in making sure that you’re getting the garbage disposal that fits your needs and quality of life the best.

How powerful of a garbage disposal do I need?

In almost every case, the most powerful garbage disposal you can find is the best option, but there are some exceptions. First, if you will always have free access to a plug, then the horsepower rating on your garbage disposal is less important. That is because the wattage rating is what determines how much power the unit has, and the horsepower is simply a measurement of its motor size. So if you have access to unlimited power, then you can use a smaller garbage disposal that will be quieter and more efficient.

Then there is the issue of what kind of food scraps you want to grind up and how much waste you want to grind up in a single session. If you only have small amounts of simple scraps to grind, then a small garbage disposal may work just fine. But if you will be grinding up lots of tough, fibrous waste, then a large garbage disposal may be a better choice.

What is the best garbage disposal on the market?

In our opinion, the Waste King legend series is one of the best options you can buy. It has a large capacity chamber, powerful motor with multiple settings, and a very durable build. However, if you want to save money, the InSinkErator Evolution Compact is another excellent option and is almost as powerful.

The second most important factor for a garbage disposal is a properly sized grinding chamber. If it is too small at about 8 gallons, then the 1/3 HP motor won't be able to grind it properly and the drain will still get clogged. Alternatively, if it is too large (like the 50+ gallons), then the unit will use more electricity to power the motor.

The last important factor is the grinding chamber material. Insinkerator units are almost exclusively made out of stainless steel, which is known for its durability. On the other hand, the Waste King Legend series has a heavy-duty plastic chamber that is equally good.

Which garbage disposal is the quietest?

In our opinion, the quietest garbage disposals out there are the Waste King Legend series. These models are also the only kind that we would recommend using with your sink because of their power and silence.

The main reason that other disposals make more noise is because they have fewer blades and the hole in the sink they are pouring into will likely be larger. The more blades you have on your disposal, the more force you use to chew through your food. This leads to lots of torque and that torque causes the garbage disposal to make more noise. But with fewer blades and the chance that the food will be going into a hole is smaller, your disposal will be quieter.


If you do a lot of cooking at home and hate to use a big industrial trash compactor to take care of all the leftovers, then a high-powered garbage disposal is your best friend. They’re not for everyone – not even every household – but for those who use them, their convenience and quickness are a blessing. We hope our reviews help you choose the best garbage disposal for your kitchen.
