Factors Affecting the Cost of Garbage Disposal Replacement

The cost of garbage disposal replacement can be influenced by several factors, including the type of unit, motor size, material, labor fees, and brand.

Garbage disposal unit type

There are different kinds of garbage disposal units. The type you choose affects the cost of replacement. One common kind is a continuous feed unit. This is often used because it works as long as power is on and the cover is open.

These types can range from $90 to $450 in price, based on brand and grinding strength. There’s also another type called batch feed unit that only works when its cover closes. It costs more but offers more safety than the first one.

Motor size

The size of the motor in a garbage disposal can affect its cost. Garbage disposals typically come in different motor sizes, ranging from 1/3 horsepower to 1 horsepower. The larger the motor size, the more powerful and efficient it is at grinding food waste.

However, a bigger motor usually comes with a higher price tag. On average, a garbage disposal with a 1/2 horsepower motor can cost between $100 and $250, while one with a 1 horsepower motor can range from $200 to $450.

It’s important to consider your specific needs when determining which motor size is right for you and your budget.


The material of the garbage disposal unit can affect the cost. There are different types of materials used, such as stainless steel and plastic. Stainless steel units tend to be more durable and long-lasting, but they can also be more expensive.

Plastic units are generally cheaper, but they may not last as long. The material you choose will depend on your budget and how important durability is to you. It’s important to consider both the initial cost and the potential future costs of repairs or replacements when making your decision.


Labor is an important factor to consider when replacing a garbage disposal. If you’re doing it yourself, there’s no cost for labor since you’ll be providing your own. However, if you decide to hire a professional, the cost can vary depending on the complexity of the installation and any additional services required.

On average, hiring a professional to replace a garbage disposal can add around $200 to $300 to the total cost. Keep in mind that this amount may change based on factors such as where you live and the specific plumber or handyman you choose.


The brand of the garbage disposal can also affect the cost of replacement. Different brands have different price ranges and quality levels. Some popular brands may be more expensive, but they often come with better warranties and customer support.

On the other hand, lesser-known brands may offer cheaper options, but their quality and durability might not be as good. It’s important to research different brands and read reviews to find one that fits your budget and meets your needs.

Cost Breakdown for Garbage Disposal Replacement

The cost of garbage disposal replacement can vary depending on factors such as the strength of the unit, additional costs like electrical wiring or removal/disposal of the existing unit, and any warranties included.

Cost by garbage disposal strength

The cost of a garbage disposal can vary depending on its strength or grinding power. Typically, a new continuous feed garbage disposal with lower to medium grinding strength will range from $90 to $250.

If you’re looking for a more powerful unit with higher grinding strength, the price can go up to $450. Remember that these prices are just for the garbage disposal itself and do not include installation or any additional services.

Additional costs to consider (electrical wiring, removal/disposal of existing unit, warranties)

Replacing a garbage disposal involves more than just buying a new unit. Here are some additional costs you should consider as a DIYer:

  1. Electrical wiring: If your current electrical setup is not compatible with the new garbage disposal, you may need to hire an electrician to make the necessary adjustments. This can cost anywhere from $50 to $200, depending on the complexity of the job.
  2. Removal and disposal of the existing unit: If you’re replacing an old garbage disposal, you’ll need to remove it first. If you’re not comfortable doing this yourself, you can hire a professional plumber for around $75 to $150.
  3. Warranties: Some garbage disposals come with extended warranties that offer additional coverage beyond the standard manufacturer’s warranty. These warranties typically range from $20 to $100, depending on the length and terms of coverage.

DIY vs. Professional Installation

Replacing a garbage disposal yourself can save you money, with an average cost of around $100 to $400 for the new unit. Hiring a professional, on the other hand, can cost between $250 and $500 including labor and materials.

Cost to replace a garbage disposal yourself

If you’re a homeowner who likes to tackle DIY projects, you may be wondering about the cost to replace a garbage disposal yourself. The good news is that if you have the skills and tools needed, you can save some money by doing it yourself.

On average, replacing a garbage disposal on your own can cost around $150. However, the total cost will depend on factors such as the type of disposal unit you choose and any additional materials or services required for installation.

It’s important to carefully follow instructions and make sure to turn off power before starting the replacement process. With some patience and know-how, you can successfully replace your garbage disposal without breaking the bank.

Cost to hire a professional

Hiring a professional to replace your garbage disposal can cost more than doing it yourself. On average, the cost for professional installation ranges from $300 to $950. However, this price can vary depending on factors like additional services needed and the complexity of the installation.

It’s important to note that while hiring a professional may be more expensive, it ensures that the job is done correctly and efficiently.

How to Save Money When Replacing Your Garbage Disposal

To save money when replacing your garbage disposal, start by getting estimates from multiple installers to compare prices. Ask about any additional fees or hidden costs that may be involved in the installation process.

Additionally, consider asking installers if they offer any discounts or promotions. You can also save money by purchasing a garbage disposal unit with a lower motor size or opting for a more affordable brand without compromising on quality.

Finally, consider doing the installation yourself if you have experience and feel confident in your abilities, as hiring a professional can add extra costs to the overall price.

Getting estimates from installers

Before replacing your garbage disposal, it’s a good idea to get estimates from installers. This will help you understand the potential costs involved and make an informed decision.

When getting estimates, be sure to provide details about the type of garbage disposal you want, any additional services needed (such as electrical wiring or removal of the old unit), and ask if warranties are included.

By comparing multiple estimates, you can find a reputable installer who offers competitive pricing for your garbage disposal replacement project.
