When comparing the InSinkErator Badger 500 vs Badger 900, it’s important to look at a variety of features. While they may seem similar at first glance, a closer look reveals distinct differences.

Some of the most important differences are performance, dimensions, construction, warranty, and the installation process. 

Each of these features plays a crucial role in the overall functionality and longevity of the disposal unit. Understanding these differences can greatly assist potential buyers in making an informed decision, ensuring they select a unit that best fits their specific needs and preferences.


In terms of performance, both models feature Dura-Drive induction motors, renowned for their reliable service.

The Badger 500 operates on a 1/2 HP motor, making it a suitable choice for smaller households with moderate disposal needs. It handles routine kitchen scraps efficiently, ensuring a cleaner kitchen and reduced waste disposal hassle.

The Badger 900 on the other hand, is equipped with a more powerful 3/4 HP motor. The extra power offers enhanced grinding and waste disposal performance, making it ideal for larger households or those with a high volume of kitchen waste.

The superior horsepower enables the Badger 900 to handle tougher food scraps and significantly reduces the chances of jams or clogs, leading to a smoother operation.


When it comes to size, the Badger 900 is slightly larger than the Badger 500. This is mainly due to its bigger motor and grinding chamber, designed to handle a higher volume of waste.

While both are compact and designed for easy fit under most sinks, those with particularly tight under-sink spaces might find the smaller Badger 500 a more convenient fit.

However, it’s worth noting that in most scenarios, the size difference is marginal and might not be a significant factor in the buying decision.

The dimension of the unit is an important consideration, but it should be weighed against other critical factors such as performance, build quality, and disposal needs.


The construction of the unit has a direct impact on its durability and lifespan.

The Badger 500, made of galvanized steel, is designed for durability. The solid construction ensures the unit can withstand the wear and tear of daily use, providing reliable service.

The Badger 900, however, takes durability to a new level with its stainless steel construction. This material choice not only enhances the unit’s robustness but also offers superior resistance to corrosion.

So, while both models are built to last, the Badger 900 offers an edge in terms of longevity and corrosion resistance, making it a more sound long-term investment for many households.


Warranty periods offer insight into the manufacturer’s confidence in their product. The Badger 500 comes with a 3-year warranty, which is pretty standard for garbage disposals in this range. It covers any potential manufacturing defects, offering peace of mind to the user.

On the other hand, the Badger 900 offers a generous 6-year warranty. This longer warranty period is a testament to its superior build quality and the manufacturer’s confidence in the product’s durability.

It provides users with extended protection against potential defects, adding value to the initial investment.


Both models from InSinkErator feature a 3-bolt mounting design, contributing to a straightforward installation process.

Being continuous feed type disposers, they allow users to add waste while the unit is running, increasing convenience and efficiency in disposing of kitchen waste.

Yet, it’s always advisable to check the compatibility of your existing plumbing and under-sink space before upgrading or changing your disposal unit.

While the Badger 500 and Badger 900 have similar installation processes, due to the larger size and the more powerful motor of the Badger 900, there could be potential issues to consider. Issues such as having enough under-sink space and the handling capacity of your existing plumbing system.

Can You Replace an InSinkErator Badger 500 With a Badger 900?

Swapping out a Badger 500 for a Badger 900 is indeed possible given their similar installation systems. Nonetheless, it’s essential to factor in the larger size and more powerful motor of the Badger 900. 

If your kitchen has a larger under-sink area and your existing plumbing can handle the increased load, then the Badger 900 would be a suitable upgrade.

It’s always recommended to consult with a professional installer to ensure a smooth transition from one model to another.

InSinkErator Badger 500 Vs Badger 900 Which One is Best?

Determining the “best” model between the Badger 500 and Badger 900 ultimately depends on your specific disposal needs, space availability, and budget.

The Badger 500, with its more compact size and less powerful motor, is more suited for smaller households with less frequent usage. It offers a more economical option for those on a tight budget without compromising on the basic functionality of a garbage disposal unit.

The Badger 900, with its higher power rating, larger size, and superior build quality, is designed to handle tougher and more frequent disposal needs.

It comes with a higher price tag but offers more durability and a longer warranty, providing more value in the long run for those willing to invest in a higher-end model.


In conclusion, both the InSinkErator Badger 500 and Badger 900 have their strengths and are designed to cater to different usage patterns and budget ranges.

The Badger 500 is ideal for smaller households or those on a tight budget, while the Badger 900 caters to larger households with more demanding disposal needs. 

Your final choice should hinge on your household’s specific needs, the volume of waste you generate, available under-sink space, and your budget.
