Most garbage disposal installation costs range between $185 to $379. That price may or may not include the warranty and any replacement parts needed for your garbage disposal if it malfunctions within the warranty period. If your unit comes with a limited warranty, it will likely be active for two to five years. Make sure to check, so there are no surprises.
The cost to replace garbage disposal units is nearly identical to the cost of installing a new unit. There may be a small additional charge to remove the old unit, anywhere from $26 to $37. Expect to pay $85 to $200 for a new disposal plus another $80 to $200 for installation.
Don’t be too quick to assume your garbage disposal needs to replacing if it stops working – all is not lost! A few common troubleshooting methods, like unplugging the unit or removing any clogs, could save you from replacing the entire unit. That said, if the blades are dull and not processing waste properly, it’s likely time for a new disposal. Sharpening the blades isn’t worth the cost of removing and replacing them — it’s more cost-effective to replace the motor and the rest of the parts at the same time by installing a new unit.
When you replace your old garbage disposal, you may need to add a new electrical outlet or rewire a plug. If that’s the case, budget an extra $145 to $175.
If you hire a handyman to install your new garbage disposal, labor costs range between $35 and $80 per hour. Plumbers charge more for labor, with costs ranging between $45 and $100 per hour. On average, labor costs to install a garbage disposal range between $80 and $200, depending on your location, if there are any other issues (such as wiring/electrical), and who you hire.
The cost to replace a garbage disposal is likely to be between $85 and $200. Costs vary based on the material your garbage disposal is made of, the feed type, and, most importantly, the size of the motor.
In this case, bigger isn’t necessarily better. Large motors cost more and tend to burn out faster, so make sure you use the correct size. A household of six people will likely need a medium motor with ½ to ¾ horsepower. Large motors, from ¾ to 1 horsepower, are best for large families or restaurants. Below is a list of price ranges based on the size of motor you choose:
There are two main styles of garbage disposals: continuous feed and batch feed. Continuous feed disposals cost $216 on average, and batch feed units cost approximately $335 on average.
Continuous feed garbage disposals are likely the type you’re most used to seeing. You flip the switch on the wall, and the disposal roars into action and stays on until you flip the switch off. They’re great for residential and commercial use and cost between $80 and $332, based on the size and brand.
Batch feed garbage disposals are safer because you put waste into the disposal while it’s off, put a cover over the entry hole, then turn the disposal on. On average, this type is also more expensive than continuous feed, coming in between $166 and $259.
The Cost to install garbage disposals will vary based on the material your disposal is made of. Stainless steel garbage disposals can cost as little as $100 but will go up based on the brand and motor size you choose. Below are the particulars of each type of material to help you choose the best one for you.
Aluminum garbage disposals are less expensive than their stainless steel counterparts, averaging $60 to $150, however, they will rust over time and aren’t as durable overall as stainless steel. Things like chicken bones shouldn’t go down aluminum garbage disposals because they can damage the blades.
Stainless steel is the best option for durability and longevity if you plan to use your garbage disposal regularly. For a small price increase, you’ll get a rust- and corrosion-resistant unit that lasts longer even with frequent use.
The average garbage disposal cost, including installation, is $1,080. The actual price for your installation could be lower, around $600, or on the higher end, at $1,550, depending on the model and size you choose. Installing a kitchen is generally between $65 and $85 for labor. Below is an example of what your cost breakdown will look like for installing a garbage disposal and kitchen sink:
In addition to the cost of the unit itself and labor charges, there are other upgrades and extra parts that may add to your total cost. These extras could be required, or they may be a matter of personal preference. Keep these costs in mind when you get estimates, and be sure to mention that you'd like them added when you have the new garbage disposal installed:
Many homeowners considering a new garbage disposal are worried about unpleasant odors. Bad smells can happen if you don’t properly clean your disposal with a specialized product. These are easy to pick up at home improvement stores or online for approximately $10 per bottle and will help prolong the life of your garbage disposal while keeping it odor-free. You can take an extra step to prevent odors by purchasing a sink flange for about $30 that covers the top of the disposal.
When it comes to saving money on garbage disposal replacement costs, taking this on as a DIY project is a great way to go. Replacing an old unit is easier than installing a disposal on a sink that doesn’t have one, as you’ll be able to see how the old unit was connected and follow suit. This can save you money on labor, but it does require some tools and DIY know-how.
If you aren’t comfortable with your plumbing or electrical skills, it’s best to leave this job to the pros. Likewise, if you’re planning on installing a new garbage disposal instead of replacing an old one, you’ll need an electrician to wire the switch. A handyperson can tackle some parts of the installation but won’t be able to do the same electrical work that an electrician is licensed to do.
Consult a plumber before purchasing a new garbage disposal, especially if you’re on septic. Septic systems have specific requirements, like a garbage disposal that can grind food very finely so it doesn’t clog the system or flow to the wrong places.
