Garbage disposal installation is one of the more straightforward plumbing jobs -- but it still requires proper wiring and drain connection. Here's the realistic cost breakdown.
Total cost including labor
A plumber or handyman typically charges $100-$200 labor to install a disposal. The unit itself runs $75-$350 depending on motor size and brand. Total installed cost: $175-$550. Mid-range units (½ to ¾ horsepower) are adequate for most households.
Choosing the right disposal
1/3 HP units ($75-$100) work for light use. ½ HP ($100-$150) handles most households. ¾ HP ($150-$200) is ideal for heavy cooking or larger families. 1 HP+ ($200-$350) is for high-volume use. Stainless grinding components last longer than galvanized.
What adds cost
No existing disposal (first-time install): may need an outlet added under the sink, adding $100-$200. Septic system homes need a disposal rated for septic use -- not all units qualify. Hard-wired vs. plug-in units: most modern disposals use a standard outlet, making DIY easier.
Lifespan and replacement
Quality disposals last 8-12 years. Signs it's time to replace: frequent resets needed, persistent odors despite cleaning, grinding noise, or leaking from the bottom. Bottom leaks mean internal seal failure -- always replace rather than repair.
Bottom line
A new garbage disposal installed professionally runs $200-$400 for most homes. It's a one-morning job that most plumbers can schedule quickly.
