InSinkErator Evolution Compact (3/4 HP) Review

Please note that this page may contain affiliate links.

If you are willing to trade in some garbage disposal space for more cabinet space without compromising on function and power, then the InSinkErator Evolution Compact is the garbage disposal for you. It was created for smaller households and families who don’t cook as much. Yet with a 3/4 horsepower motor, the InSinkErator Evolution Compact will grind tough foods like potato peels and bones.

The InSinkErator Evolution Compact has the following features:

  • Two stages of grind allowing you to insert problematic food scraps such as bones.
  • About 40% quieter than a standard disposer.
  • Vibration-free when in operation.
  • 3/4 horsepower motor.
  • 34.6-oz. capacity chamber that is made of stainless steel for added durability.
  • 4-year in-home limited warranty. For the entire warranty period, you will receive free house calls (including parts and labor) when your InSinkErator needs to be installed, repaired, or replaced. InSinkErator boasts a network of 1500 professionally trained service agents.
  • A sink mount that allows for easy installation and replacement.
  • Wall switch activation making it easy to operate.
  • Made in the USA.

SoundSeal Technology

While not as quiet as the InSinkErator Evolution Essential, the Compact still features SoundSeal Technology to deliver a much quieter performance than the average garbage disposal. It is housed in some insulation and has an anti-vibration mount, anti-vibration tailpipe mount, and quiet collar sink baffle that don’t allow any vibration to transmit sound.

34.6 oz. Grind Chamber

This InSinkErator garbage disposal is about 10% smaller than standard disposals, making it perfect for people who’ve always wanted to get a powerful one but simply don’t have the space. Inside the chamber, there are two “layers” of grind so it can handle the same tough foods as other Evolution disposals and ensure there are less clogs and jams to deal with. Whichever disposal you use, though, we strongly advise against grinding large amounts at once. Always make sure you run the disposer with cold water.

What’s In The Box

  • Quick Lock sink mount.
  • Sink baffle.
  • Jam-Buster (Allen) wrench.
  • Anti-vibration tailpipe mount.
  • Clamp.
  • Stainless steel stopper.
  • Installation instructions.

InSinkErator Evolution Compact Customer Reviews

To find out how well the InSinkErator Evolution Compact actually works, we went through hundreds of customer reviews. This is a summary of those reviews. It will give you a full picture of what to expect when you purchase the Evolution Compact garbage disposal.

Easy Installation

If you are replacing an InSinkErator Badger with the InSinkErator Evolution Compact, it will be a piece of cake to install since the Compact is intended as an upgrade to the Badger. Most people like the Badger because of its size but now with the Compact, you can have power too. If you are installing this as a new unit, it’s just as easy. The instructions cover the steps well which makes it easy for people without prior plumbing experience. However, if you are replacing from another brand, you might have to do some extra work to refit the disposer. Also, the unit doesn’t come with a power cord so if you don’t have one from an old InSinkErator, you’ll need to purchase one unless you are hard wiring the disposal.

40% Quieter

If you are familiar with InSinkErator garbage disposals you will know that the company makes two main lines: Evolution and Badger. The Badger series focuses on affordability so it is very basic. They don’t do anything to to dampen the noise level. The Evolution series, on the contrary, features SoundSeal technology to insulate the noise level. Though not as whisper quiet as the quietest InSinkErator Evolution Excel, the Compact is 40% quieter than the Badger series. One customer said it was at least 80% quieter than a model he purchased 20 years ago. The anti-vibration mount is responsible for reducing the noise level even further as the garbage disposal is not allowed to rattle the counter tops.


Worried that a smaller machine is less powerful? Not with the InSinkErator Evolution Compact! As mentioned earlier the chamber holds 34.6 oz. of food waste but features a 3/4 horsepower motor that powers a unique two-stage grind to break down the toughest foods.

Overall Summary

It’s a small but mighty and reliable garbage disposal!

Should you buy the InSinkErator Evolution Compact?

We think the InSinkErator Evolution Compact is the perfect choice for those who want to upgrade from a InSinkErator Badger. After all, the Compact was designed for people who want the compact size of a Badger and the power of the Evolution series. It was made so you don’t have to re-fit the garbage disposal when doing the upgrade, so installation is easy. But since it’s a great product, it’s a great choice for anyone really, especially if these features are important to you: 3/4 horsepower motor (we don’t recommend getting anything less than 3/4), compact chamber for more kitchen cabinet space, easy installation, and quiet operation.


  1. I currently have a Sinkmaster Bonecrusher model 850 disposal. Can it be easily replaced with the Insinkerator Evolution Compact disposal?

    1. When replacing a garbage disposal, especially with a different brand, you may need to perform some extra adjustments like replacing the mount. If unsure, you can always call a handyman and they should be able to do it for you for about $50.
