A garbage disposal in the kitchen will help you clean faster and cleaner, because not only does it get rid of the food waste, it also keeps the sink nice and clean. In Canada, the average overall cost of buying and installing a garbage disposal is between $400 and $500. Some installations can be very cheap, costing as little as $150, while the more complex installations could reach as high as $950. Disposal types, labour charges, and parts or plumbing changes will all affect the final cost.


Here is a cost guide in addition to what one should learn about the installation of home garbage disposals and their costs.




Cost of Garbage Disposal Unit


The unit itself can cost anywhere between $75 and $1,000, depending on size, features, and power. A typical house will do well with a mid-range unit costing around $150-$250.


Small models work for couples or small families that do not often cook. Larger families or households with frequent food preparation every day should opt for a more powerful unit with enhanced grinding capabilities.


Motor Power and Price


Motors are used by garbage disposals to grind food waste. Motor power is important. Motor power is measured in horsepower (HP). Here's the rundown:



  • 1/3 HP motors are appropriate for slight food waste in a small family. These range from $75 to $150.

  • 1/2 HP ones range from $100 to $200 and are appropriate for one or two individuals.

  • 3/4 HP ones are appropriate for most households with 3–6 individuals. These range from $100 to $250.

  • 1 HP motors provide robust power for heavy-duty households. These range from $200 to $500.

  • 2 HP motors are typically for commercial applications or households that generate a large amount of food waste. These machines range from $300 to $1,000.


Higher horsepower motors will last longer and dispose of more types of waste, but are also more expensive to purchase and install.


Continuous Feed vs. Batch Feed Disposals


You can have two basic types of garbage disposals:


Continuous Feed Disposals


These are switched on and operate continuously while water is flowing. You can introduce waste into the unit in operation. This is the most prevalent type. Continuous feed disposals are $75 to $500, although installation could be higher. They tend to require a nearby power outlet and perhaps wiring.


Batch Feed Disposals


These units are only activated when you seal the drain and turn on the unit. They batch grind waste. They are safer, particularly for households with children, as they only operate when covered. These units range from $200 to $650, and installation is generally simpler.


Disposal Material and Price


Disposals are composed of either stainless steel or aluminum. Aluminum Models cost less but do not last long. Stainless steel lasts longer and withstands corrosion, hence it is best for high-use kitchens. Aluminum ones range from $75 to $300, while stainless ones range from $400 to $1,100.


Select aluminum for light use and economy. Select stainless steel for a more durable, more dependable unit.


Accessories and Extra Features


Certain residents include accessories that enhance performance and safety. These additional items contribute to the overall price.


A baffle prevents silverware and debris from being ejected through the drain. It also minimizes noise. It ranges from $5 to $13.


Anti-jamming devices avoid clogging. Certain older versions require a key or wrench to unjam. The tools range from $7 to $10.


Dishwasher connectors help your dishwasher drain via the disposal. These devices are about $9 to $15.


A push-button system enables you to power the unit with a button rather than a switch. These units range from about $40.


If you include any of these, ensure your installer factors in the cost in the quote.


Electrical Work and Wiring


Most continuous feed disposals need electrical wiring. You need to hire an electrician when your kitchen doesn't have an outlet under the sink. Electricians charge $50 up to $120 per hour. Some disposals plug in, while others need to be hardwired.


Your kitchen must follow local building codes. Some cities may require a dedicated 15-amp circuit with safety features. This may increase your total cost.


Installers won't typically install new electrical parts. You might need to arrange for a licensed electrician ahead of time.


Kitchen Sink and Faucet Prices


It is not uncommon for homeowners to replace the sink or faucet at this time. If you wish to replace the faucet or sink in addition to installing the disposal, you can anticipate paying an additional $400 or more, along with the cost of replacement fixtures.


Contractors will sometimes give you a minor discount if you have it all done in one session. You might need new plumbing fixtures or fittings to go with new sinks, too, which you'll have to pay for.




What is the Cost of Garbage Disposal Installation?


Typically, installation of a unit ranges from $200 to $650 based on whether it's a replacement or installation. If you just need to replace a unit you already have, then the work should be less. A technician will just take out the old unit and install the new one using the existing fittings.


If it's your first garbage disposal, installation will be longer. The technician has to attach new plumbing and possibly perform electrical work. This adds to the cost, particularly if your kitchen isn't designed for a disposal.


One to two hours is the average time for installing a disposal. Labour charges range from $50 to $150 per hour, depending on your region and the experience of the installer. A licensed plumber usually costs more than a general handyman.




Cost to Fix a Garbage Disposal


If your garbage disposal is no longer working, you may not need to replace it. Small repairs run from $50 to $400, depending on the issue.


Some common problems are:



  • Jammed blades

  • Clogs

  • Leaks

  • Bad odors

  • Noisy noise


If your unit is still under warranty, the repair might cost nothing. Otherwise, you’ll pay for both parts and labour.




When is The Time To Replace The Garbage Disposal?


Replace it when the motor dies or the unit is ten years old or older. Most newer designs run considerably more efficiently and quietly.


Replacement fees are just like installation fees. You'll pay approximately $200 to $625 for the entire project. If your plumbing and sink are in proper condition, the project will be easy.


Disposal units leak, get clogged often, or produce unusual noises when they are old. If you notice all these, then it's high time you replaced the unit.




DIY vs. Hiring a Pro: Garbage Disposal Installation


If you know how to work with your hands and have plumbing experience, you can install a garbage disposal yourself. DIY installation costs zero except for tools and parts. Be sure to read the instructions and ask if the warranty demands professional installation.


DIY is simple if you are replacing an existing unit with an identical one. Initial installations or major upgrades must be performed by professionals. Those would prevent blunders, messes, and possible destruction.





Ways to Save Garbage Disposal Installation Cost


You can save money by selecting the correct unit and not having to do extra labour. Below are a few tips:



  • Replace with a unit of the same specs as your previous unit.

  • Select a mid-level disposal with a decent warranty.

  • Replace during a kitchen renovation and combine labour.

  • Purchase during sales or receive discounts from your contractor.

  • Take care of your disposal so you won't have to fix it.


A low-maintenance unit that suits your needs will cost you less now and in the future.




Garbage Disposal Maintenance Tips


To maintain your disposal in good working order, use it correctly. Use cold water when you grind food. Do not use grease or fibrous food items such as celery or corn husks. Clean the unit once a month with ice cubes, salt, and lemon rinds.


Never use chemical drain cleaners. They will ruin components and reduce the unit's life. If odours are present, wash the blades and splash guard. Good habits will make your disposal last longer.




What Do You Need to Budget?


A good garbage disposal with installation will set you back $400 to $500 for most Canadian homes. This means a mid-range unit with a decent motor and minimum features.


You can save money by doing it yourself or selecting a basic unit. You can also spend more if you install a new sink or require electrical work.


Get several quotes, and ensure that your installer follows safety regulations and the local building code.




Final Thoughts


Convenient removal of waste from homes is through garbage disposal. Prices for installations vary depending on the model, motor strength, type, labour, and accessories. Most homes will probably need an average-priced unit and will be installed by a professional.


Planning is essential, whether it is a replacement or purchasing a unit for the first time. Getting the right disposal type to meet the needs and budgeting for extra parts are some of the proactive planning steps. Finally, a befitting professional should be hired for the task. At the end of the day, you save effort by having a much cleaner and efficient kitchen and home.




Costs of various services and materials in this cost guide should be taken as estimates. These depend on location, preference and demands in the market.
