InSinkErator Evolution 1 HP vs Waste King L-8000 (Legend Series, 1 HP)

Which should you buy? Our verdict on both, pulled from our full The Best Garbage Disposals: 4 Compared (and One to Skip) comparison.

The Evolution 1 HP is the disposal we'd put in our own kitchen: quiet, powerful, and built from materials that last. If its premium price stings, the Waste King L-8000 delivers nearly the same grinding muscle for less, as long as you can tolerate the extra noise.

InSinkErator Evolution 1 HP

Buy it

The quiet, do-everything workhorse that grinds tough scraps without waking the house.

  • 1 HP motor with four-stage MultiGrind handles tougher scraps than single-stage budget units
  • SoundSeal insulation, which InSinkErator lists as its quietest tier
  • Stainless steel grind components resist corrosion and hold up over years of daily use
  • 10-year in-home warranty listed by the maker
  • Tall, heavy body eats up under-sink cabinet space and can crowd plumbing
  • Premium price is hard to justify for a lightly used kitchen

Waste King L-8000 (Legend Series, 1 HP)

Buy it

A 1 HP disposal at a mid-range price with a 20-year limited warranty.

  • High-speed permanent-magnet motor spins up fast and clears typical food waste quickly
  • Stainless steel grind components and a pre-attached power cord make it a genuine value
  • Twist-and-lock EZ Mount is one of the easier disposals to install yourself
  • 20-year limited warranty is generous at this price
  • Insulated, but not at the level of the Evolution's quietest-tier SoundSeal, so expect more noise
  • Lightweight body (about 12 lb) with a reinforced polymer grind chamber rather than an all-metal one
