How Much Does It Cost to Install a Garbage Disposal in Phoenix?

November 13, 2020

Revamping your kitchen or just need to replace your outdated garbage disposal? We get it! Typically, installing a new garbage disposal costs Phoenix homeowners about $300-$1,200, with the average cost landing somewhere around $700.

We know that’s quite the price range, but that’s because the cost to install a garbage disposal depends on:

  1. The motor size
  2. Type of garbage disposal
  3. Steel type
  4. Plumber you hire

In the blog below, we’ll take a look at each of these cost factors, so you can get a better idea of how much your garbage disposal installation will cost and what will affect the price.

If you’d prefer to get an exact estimate from a professional, feel free to reach out to us. Or, if you’re not quite ready to schedule an estimate, you can learn more about our garbage disposal installation services here.

Cost Factor #1: The motor size

Garbage disposal motors are measured by how much horsepower they have, and the more horsepower, the more expensive the disposal will be.

Garbage disposal motors typically range in size from ⅓ horsepower or HP to 1 HP.

Common garbage disposal motor’s include:

  • ⅓ HP
  • ½ HP
  • ¾ HP
  • 1 HP

For most homeowners, we would recommend going with a ½-¾ HP disposal. Since ⅓ HP garbage disposals aren’t the most durable, they're best for homes where the disposal is rarely used. 1 HP disposals, on the other hand, are very durable and can dispose of hard materials like chicken bones or fruit rinds.

While you can get a 1HP disposal, most homeowners tend to go with ½ or ¾ HP disposals because they can adequately dispose of your kitchen waste but aren’t the most expensive or largest option.

Keep in mind, the more horsepower the motor has, the larger the disposal will typically be. For example, a 1HP disposal will be larger than a 1/3 disposal.

Cost Factor #2: Type of garbage disposal

There are two types of garbage disposals: continuous feed and batch feed. Both types dispose of food waste via a sewer/septic system, but do so differently.

  • Continuous feed garbage disposals are the more common type of disposal and are less expensive than batch feed disposals. Continuous feed disposals turn on and off via a switch. So, when the switch is turned on, the garbage disposal is on, and when the switch is turned off, the garbage disposal turns off. Owners may prefer a continuous feed garbage disposal because you're able to put food in the disposal while it's running making it easier to use. The biggest downfall to a continuous feed garbage disposal is that it's not very safe and uses more water and electricity than a batch feed disposal.
  • Batch feed disposals only run when a stopper is in place. Essentially, this disposal works by inserting a cork like cover over the entrance of the disposal to turn the disposal on. Batch feed disposals are safer to use, and use less electricity and water than continuous feed garbage disposals. The main downfall to batch feed disposals is that if you have a large amount of food to dispose of, you need to wait and dispose of it and batches rather than continuously feeding waist down the disposal.

Cost Factor #3: Steel type

When you choose a garbage disposal, it will likely be made with stainless steel or galvanized steel.

Stainless steel garbage disposals are more expensive than galvanized steel because they are more durable and less susceptible to corrosion.

However, while stainless steel is more corrosion resistant than galvanized steel, galvanized steel is still a very durable material and will typically last the lifetime of your disposal.

Plus, most disposals have thermoplastic polymer grind chambers, which help prevent rust and corrosion regardless of the type of steel your disposal is made of.

Cost Factor #4: Plumber you hire

Usually, the more qualified and/or experienced a plumber is, the more the installation will cost. However, when it comes to having your garbage disposal installed correctly, hiring a good plumber is a must.

To find a quality plumber to install your garbage disposal, you should look for someone who:

  • Has great reviews, on sites like Facebook, Google and the BBB.
  • Will provide you with a written estimate
  • Will guarantee their work
  • Has valid insurance and a valid license
