Which One Is Best?


If you are in the market for a new garbage disposal you will have plenty of different options to choose from. There are several different companies that make garbage disposals and each company has many different models. Two of the biggest names when it comes to garbage disposals are Waste King and InSinkErator.

Because these are the two biggest names in the market, we wanted to pit one against the other to see which company offers the superior product. Waste King vs InSinkErator… Let the battle begin.

Waste King vs Insinkerator

Whenever you shop for any kitchen appliance you need to keep your budget in mind. You might be able to find a garbage disposal for $65, but you might also want a professional grade item that will cost $350 or more. Waste King and InSinkErator both have models in the entry-level, mid-level, and high-end range.

We want to compare apples to apples so we are going to look at comparable garbage disposals from each of these manufacturers.

Let’s start with entry-level options. InSinkErator has an entry-level line of garbage disposals that go by the name “Badger.” During our research we learned that the badger line of disposals is getting a lot of negative feedback from customers.

The midrange and high-end disposals made by InSinkErator are getting outstanding reviews however. When looking at Waste King disposers, all of their different models were getting great reviews from customers, including the budget models that would be comparable to the Badger line of disposals.

So when it comes to entry-level, budget priced garbage disposals, Waste King would be the clear winner.

When we look at the mid-range and high-end disposers that these companies make, the customer reviews are outstanding for all of them. Prices are comparable and customer reviews are great for both companies, but there are a couple of areas where Waste King models have an advantage.

Here are two of the higher end 1 Hp models for both brands to look at. You will find that they are very much equal and you won’t go wrong with an of them. The Waste King is less expensive but the Insinkerator features whisper quiet technology and is a much quieter garbage disposal.

  1. Insinkerator Evolution
  2. Waste King L-8000

When comparing disposers with the same horsepower, the Waste King models typically operated at higher RPMs. If horsepower is equal, the motor that spins faster is the one most people would choose.

The other area where Waste King has an edge over InSinkErator is that the Waste King disposers have longer warranty periods than comparable InSinkErator models.

At this point in our Waste King versus InSinkErator battle, it looks like Waste King is pulling ahead is the clear winner when it comes to the smaller Hp models. It’s not all bad news for InSinkErator however.

When researching reviews for these garbage disposals, most customers talk about how easy it is to install the InSinkErator disposals.

If you are replacing an older InSinkErator with a new one, the installation will really be easy because the InSinkErator models come with a Quick Lock Sink Mount that is designed to make installation a simple remove and replace job.

In conclusion, when pitting Waste King vs InSinkErator, we would have to say that Waste King comes out as the winner. The budget priced InSinkErator models were getting poor reviews from customers while Waste King disposers are getting great reviews regardless of the price point of the models we looked at.

Waste King also has motors that operate at higher RPMs, longer warranty periods and even slightly lower prices when looking at comparable InSinkErator models. InSinkErator does make very high quality garbage disposals that are getting great reviews from customers, but after conducting our research we would have to give Waste King a bit of an edge.

    I would point out, as one youtube commenter did, that for the “very high end” ISE seem to get better reviews than the “high end” waste king (though lesser warranty). It almost feels as if waste king doesn’t really “have” a high end, since theirs are so much cheaper LOL.

    My only problem with Badger 5s is that the grind chamber corrodes and lets water into motor or right out the side walls into the cabinet, though this takes a number of years. The newer models, with more plastic, get less corrosion, but the bottom of the grind chamber is still steel, which will eventually perforate. I have a 20 year-old Sears disposal with a plastic and stainless steel chamber which has never leaked, so I’d look for these materials in a new one.
