Buyer’s Guide

Small homes are a big trend right now. This is being driven by a variety of factors, such as Baby Boomers hitting retirement age, younger generations being squeezed financially, and general concern about the environment.

But having a small home doesn’t have to mean foregoing a comfortable lifestyle with modern amenities. In fact, the opposite truth is another driving force in this trend: Modern technology makes it possible to fit a full and comfortable life into fewer square feet.

A small kitchen may need more tech to make it bearable, not less. But that tech needs to fit within the allotted footprint.


The smallest motors start at 1/3 Horsepower (HP). This is for a one or two-person household that doesn’t put a lot of wear and tear on the unit. Think of a household that eats out a lot and doesn’t do a lot of entertaining.

The 1/2 HP motors are for a one-to-three-person household. They can handle a bit more capacity. Think of a household with one to two people that does more home cooking and entertaining or a three-person household that eats out a lot and doesn’t entertain much.

The largest motors on compact models are 1 HP. They can easily handle a household of four people. Alternatively, they can handle a household of one to three people who entertain somewhat regularly.


If space is at a premium, make sure to get the measurements of any models that interest you. Then check to see if it works in your kitchen.

Compact models will easily fit standard-sized cabinets and should fit smaller cabinets. But it’s a lot of hassle to purchase something, try to install it and then realize it doesn’t fit. So always check the measurements when designing a small space.

Most Compact Units Are Fairly Basic

You mostly won’t find a lot of bells and whistles with compact units. Some boast extra features like soundproofing, but you aren’t likely to find a 2-stage grinding mechanism or other fancy technology.

The general assumption is that you will not be using it that much. If you want a lot of bells and whistles, you probably need to make sure you can afford to devote the space to a larger unit.

There are still some differences between units. Don’t forget that you can elect to install an air switch to improve safety and convenience even in a small space.

If You Are On A Septic System

Generally speaking, garbage disposals are not compatible with septic tanks. If you are off-grid and using a septic system, think twice before installing a garbage disposal.

The use of a garbage disposal with a septic system will tend to drive up maintenance costs for the septic system. Septic systems are not intended to be receptacles for food waste, no matter how finely ground it may be.

This is a sales tactic when you see garbage disposals claiming they work well with a septic system. It is not actually a good idea to combine a disposal with a septic system.

Our Best Choice

We really like number 1. InSinkErator Garbage Disposal, Badger 5, 1/2 HP Continuous Feed. For the majority of small households, this will be the sweet spot for performance.

In most cases, a 1/3 HP motor will be inadequate. However, a 1 HP motor will tend to be overkill. A 1/2 HP will be just right. Plus, InSinkErator has a lot going for it, so it is the most popular brand in the US.
