Waste King vs InSinkerator: Battle Of The Top Garbage Disposals

The benefits of a garbage disposal are undeniable. These appliances do a great service in the kitchen by getting rid of food waste from cooking as well as from the dishwasher. The disposal does a dirty job, but one that is almost essential to running your kitchen.

The newest, most advanced disposals are loaded with features for anyone looking to install or upgrade their disposal system. When looking at disposals, the main question you will be asking yourself is likely whether you should get an InSinkErator disposal or a Waste King.

InSinkErator and Waste King have made it to the top of the disposal market and are the two biggest names in garbage disposals. These are the highest quality disposals available to residential users. While basically everybody recognizes the InSinkErator name, Waste King also produces some top line disposals. They are a division of Moen and produce not only residential and commercial disposals, but various other kitchen products under different names.

How do I choose?

The sheer number of different disposals that both Waste King and InSinkErator offer can be staggering. When you look solely at how many disposals each brand offers you will find that InSinkErator offers many options and has actually expanded beyond their classic Badger series to create the more advanced Evolution series.

Waste King offers nine variations of disposals for their Legend series. InSinkerator has three Badger series options and five Evolution series options. All three lines of disposals are very different from each other.

When looking at Waste King vs InSinkErator brand disposals you will notice that both the InSinkErator lines are sleek and modern in design, while the Waste King is larger and not as presentable. This may turn some people off from the Waste King, but you should remember that the disposal goes inside of the cabinet and does not technically have to look super modern.

At the very bottom of the price range for either brand of disposal you will find the Waste King L-111. It is a 1/3 horsepower model and can be purchased online for as little as $65. The lowest price for an InSinkErator 1/3 horsepower model is somewhere between $75 and $85.

While these two disposals are similar in features, the Waste King beats InSinkErator with a two-year warranty compared to the Badger's one-year we come to you warranty.

Are the warranties always so short?

The InSinkErator warranties can get as long as seven years for more expensive disposals with grinding parts guaranteed for life. On the other hand, Waste King also offers lifetime warranties on parts and a 10-year service warranty on their best disposals.

What other options are available?

When looking at Waste King vs InSinkErator in terms of available options, InSinkErator has the most upgrades available for disposals in their Evolution line. The Evolution disposals feature two or even three grinding stages to make short work of your food scraps. You can also get advanced safety features to eliminate the need for manually fixing jams in the disposal.

Both Waste King and InSinkErator offer models with up to one horsepower. These are the most powerful options and can be purchased in the Badger line of disposals as well.

Both manufacturers offer easy installation hardware for quick hook-up. InSinkErator models can be interchanged at the sink drain flange regardless of whether you are putting in a Badger or an Evolution.


There are considerable differences between Waste King and InSinkErator. Waste King may be a lesser known disposal in general, but their Legend disposals offer superior service warranties. InSinkErator doesn't skimp on warranties, but they do fall short when you look at Waste King vs InSinkErator.

While warranties are a huge consideration, Waste King also boasts being able to match power ratings with InSinkerator at a lower price point.

Power is only half of the equation when looking at disposals. InSinkErator has put a lot of effort into making sure their disposals are whisper quiet. InSinkErator also offers more grinding stages and advanced features in general. The Badger and Evolution disposals also have a polished, professional look, but honestly does it matter if it's under your sink?

You just have to know what you want most when you are buying a disposal.

I just installed a garbage disposal I bought from Costco. It does not “suck” the food down into the disposal as all other disposals I have had did. I replaced the splash guard, thinking this might be the problem but it wasn’t. Do you have any idea why this is happening? I am considering replacing it with a Waste King 8000 but don’t want to have the same problem.

    It may be underpowered. I have the Waste King 8000 and it works great.
