That awful grinding noise from your kitchen sink has gone silent-or worse, your garbage disposal won’t turn on at all. The problem is clear, but now you have another question: how much does it cost to replace a garbage disposal in Spokane?
Similarly, addressing underlying water quality issues can protect your entire plumbing system. Hard water, for example, can lead to mineral buildup that damages pipes and appliances. Installing Water Softeners is a common solution to prevent this kind of long-term wear and tear.
The fear of being overcharged or surprised by hidden fees can make a frustrating situation even worse. That’s why Division One Plumbing believes in transparent, upfront pricing and honest service. This 2026 guide breaks down the complete cost of garbage disposal replacement-including the unit, professional labor, and the factors that affect your total price.
By the end, you’ll know what a fair price looks like, how to budget, and why hiring a licensed plumber is the easiest, most reliable option.
Average Garbage Disposal Replacement Cost in Spokane
Across the U.S., homeowners typically spend between $250 and $650 for a complete garbage disposal replacement, including both the unit and professional installation. Locally, prices in Spokane, WA, tend to fall right within that range.
Your total cost depends on the disposal model and the complexity of the installation. Here’s a simple breakdown:
| Cost Component | Average National Price Range |
|---|---|
| New Garbage Disposal Unit | $100 – $400 |
| Professional Labor | $150 – $250 |
| Total Average Cost | $250 – $650 |
If you’re installing a disposal for the first time (rather than replacing an old one), your plumber may need to add new plumbing or wiring, which can increase the final price.
Garbage Disposal Units and Prices
The type and power of your disposal play the biggest role in the final cost. Units are categorized by horsepower (HP), with more powerful models able to grind food waste more quietly and efficiently.
-
1/3 to 1/2 HP: Best for small households and light use. ($100 – $180)
-
3/4 HP: A great mid-range option for average families. ($180 – $280)
-
1 HP or more: Ideal for large families or those who cook frequently. ($280 – $400+)
You also have two main types:
Continuous feed disposals operate with a switch and run continuously while adding waste.
Batch feed disposals only run with a stopper in place, offering added safety.
Both options work well-the difference comes down to budget, usage habits, and household preferences.

5 Key Factors That Affect Garbage Disposal Replacement Cost
Every kitchen and plumbing setup is different. Here are the five main things that affect your total price for a garbage disposal replacement in Spokane:
1. Garbage Disposal Type & Power
Higher-horsepower models cost more but can handle larger food scraps and operate more quietly. Investing in a higher-quality unit can save money in the long run by reducing clogs and breakdowns.
2. Condition of Existing Plumbing & Electrical
If your existing connections are in good shape, the job is quick and easy. But if your plumbing is corroded, leaking, or your electrical outlet isn’t properly grounded, additional repairs or modifications may be required.
While you’re already addressing the plumbing, it can be a good time to think about other kitchen updates. For inspiration on how cabinet refinishing can refresh the entire look of your kitchen, you can visit Cabinet Painting Denver to see examples of their work.
3. Licensed Plumber vs. Handyman
While a handyman might offer a slightly lower hourly rate, only a licensed and insured plumber can guarantee safety, code compliance, and warranty coverage. A poor installation can lead to leaks or electrical hazards that end up costing more to fix later.
4. Geographic and Local Labor Rates
Labor costs vary across regions. Spokane homeowners are lucky-our local rates for professional plumbing services are among the most competitive in Washington state.
DIY vs. Professional Garbage Disposal Replacement
One of the biggest questions homeowners ask is whether they can replace their garbage disposal themselves. While DIY installation might seem like an easy way to save on labor, it’s not always the best long-term choice.
The Hidden Costs of DIY Work
A proper installation requires specialized tools-wrenches, fittings, plumber’s putty-and a good understanding of how plumbing and electrical systems interact. What takes a trained plumber an hour or two can take a homeowner half a day or more, especially if something unexpected arises.
Why Professional Installation Is Worth It
A professional plumber ensures everything is properly sealed, grounded, and leak-free. Division One Plumbing also tests your system before leaving, giving you total peace of mind that your disposal will work flawlessly for years to come.
Save yourself the headache. Schedule a professional installation.

Frequently Asked Questions
How long does it take to replace a garbage disposal?
A professional plumber typically completes the job in about 1-2 hours, including removal, installation, testing, and cleanup.
Can a garbage disposal be repaired instead of replaced?
Sometimes! If your disposal has a jam or reset issue, it can often be fixed. But if the motor is dead or the casing is cracked, replacement is the smarter and safer choice.
What are the signs that I need a new disposal?
Common signs include loud grinding or humming noises, bad odors that won’t go away, leaks from the unit, frequent jams, or a motor that won’t start.
Do plumbers provide the garbage disposal, or should I buy it myself?
Yes. Division One Plumbing can supply a high-quality unit that fits your kitchen’s needs-or we’ll install one you’ve already purchased.
How long should a new garbage disposal last?
A quality, professionally installed disposal typically lasts 8 to 15 years, depending on frequency of use and maintenance.
Is it more expensive to add a disposal for the first time?
Yes. First-time installations usually require additional wiring or plumbing adjustments. Our plumbers always provide a clear, up-front estimate before any work begins.
