Buying Guide – Best garbage disposal for undermount sink

Here are three factors to consider when purchasing a garbage disposal to make the best decision for your needs.


The size of your garbage disposal is essential for more than just space considerations. A larger model might have more power, but it also might not fit in the cabinet under your sink.

If you’re looking for a compact garbage disposal that will still get the job done, you might have to sacrifice some power for the smaller size.


The power of garbage disposal is essential when considering what types of food it can grind. Disposal with horsepower can grind more laborious particles, such as melon rinds.

On the other hand, a removal with less power is better for softer food, such as meat trimmings.


Regarding residential garbage disposals, there are two main grinding chambers: stainless steel and galvanized steel. While stainless steel is more expensive, it is also more resistant to corrosion and rust.

We recommend opting for a stainless steel chamber if you can afford the extra cost. Galvanized steel has a rust-resistant coating that protects it from corrosion.

However, this coating can be damaged, and the steel will start to rust when it is. Plastic grinding chambers are more affordable and also resistant to corrosion. However, plastic is not as durable as steel and can crack over time.

Noise Level

There are a few things to consider when purchasing a garbage disposal unit, one of which is the noise factor.

Some units can be pretty loud, so if noise is a sensitivity for you, look for a team with an excellent grinding chamber that will prevent jamming and help to deaden the noise if you’re looking for a way to reduce the noise coming from your unit, look for one with sound-seal technology.

This insulation helps to deaden the sound so you can enjoy a quieter living space.


The motor at your disposal is essential for two reasons. First, a powerful engine can grind up leftovers and scraps ideally and in less time.

Second, a powerful motor can handle an enormous volume of trash. So if you have a large family, get a disposal with a 2 HP motor. We recommend getting disposal with a ½ or ⅓ HP motor for regular light use.


What are garbage disposals like in the eyes of the plumber?

Plumbers do not take garbage disposal units lightly. Garbage disposals are used by professional plumbers to help treat kitchen waste from fats, oils and grease.

With a garbage disposal unit you can easily grind them up into little bits before disposing into the sink so that you don’t have any unpleasant odors or bugs coming with it when you dispose later.

Is a garbage disposal with a higher HP better?

There are several things you should take into account when purchasing a garbage disposal. The horsepower, the effectiveness of the grinding, and the noise level are a few of these.

Furthermore, more horsepower is preferable in this case. Fewer jams, finer food waste pulverization, and fewer clogged drains are all benefits of increased horsepower.

However, a model with more horsepower typically requires more room than other models. So before investing in one, make sure you have enough under-sink space for it.

Are lemons safe to put in the garbage disposal?

Lemons and limes are very useful for cleaning the disposal of your garbage disposal. These citrus fruits contain citric acid, which helps to remove any built-up slime and grime that may be clogging up your drain.

Lemons and limes can also help to freshen up your sink or shower by rubbing their rinds directly onto metal surfaces (such as taps or bath panel) to remove harsh chemical smells, as well as leaving a fresh scent behind.
