How does it feel to you that you are done cooking your dinner and your sink is full of scraps, and instead of scraping the plates into the trash can, you can simply flip a switch? Within a few seconds, everything is clean and whisked away by an appliance. That’s what garbage disposal does. But before enjoying this, you must know how it actually costs.
This is the most asked question by the homeowners, and the answer isn’t one flat fee. The costs depend on multiple factors like the type of unit you buy, who will install it, the labor cost in your neighborhood, and even the complexity of your plumbing or electrical setup.
This detailed blog will help you cover all the aspects you need to know about the installation costs, from average to hidden expenses, and even tips on how to save money. By the end, you’ll know not only what to budget but also how to choose the right disposal, when to hire a plumber, and how to avoid common pitfalls.
Why Install a Garbage Disposal?
Before diving into costs, you should know why so many households opt for garbage disposals in the first place. A garbage disposal (or garbage disposer, as it’s called in Canada) is a device installed under your kitchen sink that grinds food scraps into tiny particles. These particles are then washed away through your plumbing system.
The benefits are pretty clear:
- Less kitchen waste going into your trash can
- Fewer odors and pests caused by food scraps
- Faster cleanup after meals
- Reduced chances of clogged drains when used correctly
For busy families, it’s almost a kitchen essential. But just like any home improvement, the cost depends on the specifics of your situation.
The Average Cost of Garbage Disposal Installation
So let’s get straight to numbers.
On average, garbage disposal installation costs between $150 and $450. This includes both the price of the unit and professional labor.
Here’s a quick breakdown:
Cost Factor | Low End | High End |
Basic Garbage Disposal (unit only) | $70 | $150 |
Mid-Range Disposal | $150 | $250 |
High-End Disposal | $300 | $500+ |
Labor Cost | $80 | $250 |
Average Total Installation | $150 | $450+ |
Pro Tip: If you’re replacing an existing garbage disposal with a similar model, installation is usually cheaper because the plumbing and electrical connections are already in place.
New Garbage Disposal vs Replacement: Cost Comparison
One of the biggest cost factors is whether you’re installing a brand-new disposal or replacing an old one.
- New Garbage Disposal Installation: $250 to $500+ (requires new wiring, plumbing adjustments, sometimes even sink modifications).
- Replacement of Old Disposal: $120 to $300 (quicker process since the connections are already set up).
Labor Costs
Most homeowners hire a plumber or handyman for garbage disposal installation. Labor costs typically fall between $80 and $250, depending on:
- Your Location: Larger cities (like Los Angeles or New York) have higher rates.
- Complexity: If your sink doesn’t already have a disposal, expect higher costs.
- Experience of Installer: Licensed plumbers may charge more than general handymen.
For example
- In Los Angeles, the plumber cost to replace a garbage disposal may be closer to $200–$250.
- In smaller towns, the labor cost to replace a garbage disposal might drop closer to $100–$150.
DIY vs Hiring a Professional
If you’re handy with plumbing, DIY installation can save you $100–$200. But for most homeowners, hiring a pro is safer. Incorrect installation risks leaks, electrical issues, or voided warranties.
That’s where Best Choice Plumber comes in our team handles everything from setup to safe wiring, so you don’t have to stress.
Additional Costs to Consider
If you think that buying and the installation of a disposal are the only costs, then you need to read this because this might change your view. In some cases you might need a power outlet under the sink that usually costs around $100 to $200 and this isn’t it, sometimes even small parts like sink flange or stopper aren’t included, that may cost you and additional another $20 to $50.
If you’re replacing an old unit, some plumbers also charge $30 to $50 for removal and disposal. And if you want peace of mind, extended warranties are often offered for around $20 to $50 more. These aren’t huge add-ons, but they’re worth keeping in mind when budgeting. These aren’t huge add-ons, but Best Choice Plumber always explains them upfront so you’re never surprised by hidden fees.
How Long Does Installation Take?
If you hire a plumber, installation typically takes 1–2 hours for a replacement and 2–3 hours for a new installation. The time impacts the labor cost, especially if your installer charges by the hour instead of a flat rate.
Choosing the Right Garbage Disposal Unit
One question many homeowners have is: What size garbage disposal do I need?
Disposals are measured by horsepower (HP). Here’s a quick guide:
- 1/3 HP – Small households with light usage.
- 1/2 HP – Average family use.
- 3/4 HP – Quieter and stronger, good for frequent cooking.
- 1 HP or more – Large families, heavy use, or small commercial kitchens.
Garbage Disposal Repair vs Replacement
Sometimes you don’t need a brand-new unit, just a repair
- Garbage Disposal Repair Cost: $70 to $150 (depending on the issue).
- Plumber for Garbage Disposal Repair: Around $80–$120 per visit.
- Garburator Repair in Canada: Similar pricing but may vary by province.
If the unit is more than 10 years old, replacement is usually more cost-effective.
Cleaning and Maintenance
To get the most out of your disposal, regular cleaning is key. Here’s how to clean your garbage disposal safely:
- Run cold water during and after use.
- Grind ice cubes to sharpen blades.
- Use citrus peels for freshness.
- Avoid putting grease, bones, or fibrous foods inside.
Simple maintenance can extend the life of your disposal and delay replacement costs.
Commercial Garbage Disposal Costs
For restaurants or larger kitchens, commercial garbage disposal units are significantly more powerful and costly. They can range from $500 to $2,500, with installation costs often starting at $300. These units handle larger volumes and are built for heavy use.
Best Choice Plumber helps you here as they install heavy-duty commercial units built for daily, large-volume use.
Who Installs Garbage Disposals?
If you’re not doing it yourself, you’ll need to hire:
- A licensed plumber (most common)
- A handyman service (for straightforward replacements)
- Some kitchen remodeling contractors also include disposal installation in their services
When hiring, always ask:
- Are they licensed and insured?
- Do they charge a flat rate or hourly fees?
- Do they include the removal of the old unit?
Final Thoughts
A garbage disposal is not a necessity for your kitchen, but believe me, it is no less than that, it’s one of the most practical upgrades your kitchen would need. Just by spending a few hundred dollars, you can do your work very efficiently, reduce the waste, and make the kitchen clean in no time.
The cost of disposal is quite manageable financially for most of the families, and if taken proper care, it can last up to 8-12 years.
If you’re on a budget, consider an affordable unit paired with an installation. If you’re focused on long-term performance, consider investing in a higher-end model and hiring a licensed plumber. Either way, this small upgrade delivers a big improvement in daily life.
