Best Garbage Disposal for Farmhouse Sinks 

Farmhouse sinks are usually larger and more difficult to install than standard kitchen sinks. On top of that, these types of kitchen sinks can be quite heavy, especially if they are made up of fireclay. Due to these factors, not every type of garbage disposal will fit underneath your farmhouse sink.

For instance, if the garbage disposal is too tall, it may not fit underneath the farmhouse sink due to the limited space underneath the sink. And if the disposal unit is too heavy, it will add unnecessary stress to the farmhouse sink and the frame supporting it. 

With that in mind, the best garbage disposal for farmhouse sinks should be compact and light to fit perfectly underneath the cabinet without putting too much stress on the sink. But where do you get a garbage disposal that meets these requirements? 

Well, you’re on the right track! In this article, we’ve reviewed the X best garbage disposals for farmhouse sinks to help you find the perfect unit for your kitchen!

Best Garbage Disposal for Farmhouse Sinks Buyer’s Guide (Important Things to Consider)

• Available cabinet space  

The size of the kitchen cabinet is one of the most important factors to consider when buying a garbage disposal for your farmhouse sink. For that, it’s crucial to the space available under the farmhouse sink before you settle on any model. This will help you narrow down and determine the perfect garbage disposal size for the sink. 

Generally speaking, most countertops in the United States are about 36” or 3 ft high on average. On the other hand, a farmhouse sink can take up a space of about 12” or 1 ft in the kitchen cabinet. Assuming you include 6” to account for the space allowance above and below the sink, you’ll have about 18” of available cabinet space for the disposal. Therefore, the best garbage disposal for farmhouse sinks should not exceed a height of 18”. 

• Garbage Disposal size 

After determining the available cabinet space under your farmhouse sink, the next step is to find the right garbage disposal size for your home. Typically, compact-sized disposal units are recommended for homeowners with farmhouse sinks. This will help you use the space under the countertop efficiently and ensure the disposal fits perfectly under the farmhouse sink. 

• Grinding power 

The grinding power of a garbage disposal refers to the appliance’s power per pound. Unfortunately, this is not usually specified by the manufacturer as it goes beyond the unit’s HP. 

Instead, you need to put both the unit’s motor power and grinding chamber capacity into consideration. For instance, a 30 oz capacity disposal unit with a 1 HP motor has better grinding power than a 50 oz capacity with the same horsepower. 

• Noise reduction 

Grinding produces a lot of noise, which is not an exception with garbage disposals even though they’re hidden under the kitchen sink. For that, it’s important to look for a unit that is equipped with various noise-reducing mechanisms to minimize the amount of noise it produces while running. Good examples of garbage disposals for farmhouse sinks that produce the least amount of use in their operation are Evolution Excel and Evolution Compact. 

• Installation 

Most garbage disposals are relatively easy to install since they’re designed to fit in various types of kitchen sinks. Also, their topmost part easily connects to the sinkhole, eliminating the need for any drain hardware. 

Installing garbage disposals in farmhouse sinks is even easier since all sinkholes have the same cut. In most cases, it’s as easy as the pop-and-lock method. However, it’s important to check the manufacturer’s manual to determine how to properly connect your specific garbage disposal to the farmhouse sink. 

Also, you need to be careful when installing the garbage disposal to your farmhouse sink, especially if it’s made from fireclay. This is because fireclay sinks have a thicker bottom compared to other types of farmhouse sinks, making their installation difficult. 

For instance, the Insinkerator models we’ve listed are compatible with fireclay farmhouses with a thickness of between ½” and ¾”. So, if your sink is thicker than ¾”, you’ll certainly need a sink flange extender.
