The cost to replace a garbage disposal in 2025 depends on the quality of the unit and the condition of your plumbing. On the low end, a basic model may cost around $500 installed. Higher-end disposers with stainless steel parts and longer warranties can run $800 to $1,000 or more.
We’ve replaced many of these over the years. And we always remind customers that the price depends on more than just the unit itself. Labor, drain adjustments, and even small changes under the sink can all raise the final cost.
Comparing Garbage Disposal Options
What Does a Basic Model Cost?
You can find builder-grade or “cheapy” disposals at the hardware store for as little as $100. These are often:
- Noisy during use
- Made of parts that rust after a few years
- Covered by short warranties (one year or less)
Even though the unit is cheap, the cost to install it professionally will still bring your total to around $500.
Why High-Quality Disposers Cost More
If you want something that lasts and works quietly, a high-end model is worth it. These models often include:
- Stainless steel interiors that resist rust
- Higher horsepower for better grinding
- Longer warranties (7–10 years)
Installation of a quality unit like this usually costs between $800 and $1,000, but it often lasts 10 years or more.
Key Takeaway: A better disposer costs more up front, but you won’t need to replace it again anytime soon.

What Else Can Affect the Price?
Even with a new disposer, there are other parts under the sink that may need to be updated.
Old or Damaged Drain Lines
If the P-trap or drain lines are old and corroded, they can crumble when we remove the old disposer. In that case, we’ll need to replace those pipes, which adds parts and labor.
Sink or Drain Changes
If you’ve installed a deeper sink, the new disposer may sit too low. We might need to rework the drain line to connect it properly. That can add a few hundred dollars, depending on how much piping we need to adjust.
Pro Tip: If you’re replacing the sink too, let us know before we install the disposer. It may save you time and money on added plumbing changes.
Want an Air Switch Instead of a Wall Switch?
Some people choose to add an air switch instead of using a wall switch. This switch fits into a hole in the sink or counter and makes it easier to turn the disposer on and off with wet hands. Installing an air switch adds to the overall cost but offers convenience and safety.
Does the Size of the Disposer Matter?
Make Room for Larger Units
Some high-power disposers are wider or taller than basic models. If you have shelving under the sink, we may need to trim or remove part of it to fit the new unit. This is usually a small extra charge, but it’s something to keep in mind when selecting your unit.
Key Takeaway: Always check the space under the sink before buying a large disposer. It can prevent surprises during installation.
Final Thoughts: Is a Better Garbage Disposal Worth It?
The cost to replace a garbage disposal depends on the quality of the unit and your plumbing setup. Basic models start around $500 installed, but you’ll likely be replacing them again soon. A higher-end model may cost $800–$1,000 but can last 10 years or more.
When you choose a better disposer and have it installed the right way, it’s one less thing to worry about. And if there’s ever a problem, we’re here to help.
