The Best Garbage Disposals: 4 Compared (and One to Skip)

RBE top pick

InSinkErator Evolution 1 HP

Check price on Amazon See why it wins Compare all

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.

A garbage disposal is one of those appliances you only think about when it jams, stinks, or rattles the whole cabinet. We weighed maker specifications and owner reports across continuous-feed and batch-feed units to sort the genuinely good buys from the ones you'll regret. The result is two easy recommendations, one that's only right for specific households, and one classic builder-grade model we think most people should skip.

RBE top pick

InSinkErator

InSinkErator Evolution 1 HP

Buy it

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

Best for: Busy family kitchens that cook from scratch and want the quietest, most capable continuous-feed unit.

$$$ · premium

Why we like it

• 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

Know before buying

• 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

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.

Best for: Value-focused buyers and DIY installers who want strong grinding and can accept a bit more noise.

$$ · mid-range

Why we like it

• 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

Know before buying

• 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

Moen

Moen GX Series GXB75C (Batch Feed, 3/4 HP)

It depends

A batch-feed unit that runs only with its cover in place, built around galvanized grind parts.

Best for: Households with kids or safety-conscious cooks who want a batch-feed unit and accept a slower workflow and galvanized grind parts.

$$ · mid-range

Why we like it

• Batch feed with the batch cover as the on/off control, so it cannot run with an open drain
• No wall switch needed, which simplifies installs in kitchens without existing switched power
• 2700 RPM permanent-magnet motor, SoundSHIELD insulation and a pre-installed power cord
• Universal Xpress Mount fits most existing 3-bolt mounts, including InSinkErator's, per Moen
• 10-year limited warranty with in-home service

Know before buying

• Batch workflow is slower: you load, cap, and grind in stages rather than feeding continuously
• Galvanized steel grind components, where the two buy picks use stainless
• The cover is the switch, so a misplaced cover stops the disposal

We'd skip it

InSinkErator

InSinkErator Badger 5 (1/2 HP)

Skip it

The builder-grade default that most owners outgrow within a couple of years.

Best for: Light, occasional users or landlords furnishing a rental on the tightest possible budget.

$ · budget

Why we like it

• Cheap and compact, so it fits tight cabinets and tight budgets
• Simple, widely stocked, and easy to find a like-for-like replacement

Know before buying

• Galvanized (not stainless) grind components are prone to corrosion and rust over time
• Single-stage 1/2 HP motor jams on fibrous or hard waste that stronger units shrug off
• Standard sound level, without the SoundSeal insulation of the Evolution 1 HP
• Owner reports point to a shorter service life

How we judged the field

We don’t run our own appliance lab. Instead, we work from maker specifications and the patterns that show up across owner reports, then weigh them against what actually matters day to day in a kitchen. For garbage disposals, five things separate a keeper from a regret: grinding power (enough motor and enough grind stages to avoid jams), noise (insulated bodies are dramatically more livable), build materials (stainless grind components outlast galvanized ones), safety and feed type (continuous vs. batch), and long-term durability as reflected in warranties and repeat-owner feedback. We deliberately included both continuous-feed and batch-feed designs, and we kept one budget favorite in the mix specifically to explain why we’d steer most people away from it.

This is the unit we’d fit in our own kitchen. The 1 HP motor paired with four-stage MultiGrind handles the tougher scraps that stall cheaper single-stage disposals, such as fibrous vegetable peels. Just as important, it uses SoundSeal insulation, which InSinkErator lists as its quietest tier. Stainless steel grind components resist corrosion, and the 10-year in-home warranty signals a build meant to last. The catch is size and price: it’s a tall, heavy body that crowds an under-sink cabinet, and it costs a clear premium. For a household that cooks daily, that premium buys quiet and longevity, and it’s worth it.

The L-8000 is the value counterpunch. Its high-speed permanent-magnet motor spins up fast and clears everyday food waste with genuine 1 HP authority, and it uses stainless grind components rather than galvanized parts. A pre-attached power cord and a twist-and-lock EZ Mount make it one of the more DIY-friendly installs, and the 20-year limited warranty is generous for a mid-range unit. The trade-off is noise: its insulation is lighter-duty than the Evolution’s quietest-tier SoundSeal, so expect it to run louder. If a bit more noise doesn’t bother you, this is a lot of disposal for the money.

This is the batch-feed option, and whether it’s right for you comes down to safety. Moen lists the batch cover as its on/off control, so it only grinds with the cover in the drain and cannot spin with an open, hand-accessible chamber. That makes it a reassuring choice for homes with young kids, and because there’s no wall switch to activate, it can simplify installs in kitchens that never had switched power for a disposal. Moen pairs a 3/4 HP, 2700 RPM permanent-magnet motor with SoundSHIELD insulation, a pre-installed cord, a mount that fits most existing 3-bolt assemblies, and a 10-year limited warranty with in-home service. Two trade-offs keep it at “depends”: you load, cap, and grind in batches, which is slower, and Moen lists the grind components as galvanized steel, the material this review counts against the Badger 5. Buy it for the safety model, and accept that it gives up the stainless parts of the two buy picks.

The Badger 5 is the disposal you’ll find pre-installed in countless homes and stacked by the pallet at the hardware store, and that ubiquity is exactly the trap. It isn’t unsafe - it’s just built down to a price. Its grind components are galvanized rather than stainless, so they corrode sooner; the 1/2 HP single-stage motor jams more readily on fibrous or hard waste than a 1 HP multi-stage unit; and it lacks the SoundSeal insulation of the Evolution 1 HP. Owner reports describe a shorter service life. It’s fine for a rental or a kitchen that rarely sees real cooking. For everyone else, the modest upfront saving tends to evaporate into an early replacement.

InSinkErator Evolution 1 HP vs. Waste King L-8000: which should you buy?

These two are the real decision for most shoppers, and they split along a single axis: quiet-and-refined versus loud-and-affordable. Both have 1 HP motors and stainless grind components, so raw capability is close. The Evolution wins on livability - its SoundSeal insulation is the quietest tier InSinkErator lists, and its four-stage grind is built for tougher scraps. The Waste King wins on value - you get comparable grinding muscle, an easier DIY mount, and a 20-year limited warranty for less money, with noise as the price of admission. If your kitchen is open-plan or you simply hate appliance racket, pay up for the Evolution. If you want the most grinding power per dollar and the noise is a non-issue, the L-8000 is the smart buy.

What to look for

• Match horsepower to how you cook: 3/4 HP to 1 HP handles most households; 1/2 HP suits light, occasional use.
• Prefer stainless grind components: they resist corrosion and outlast the galvanized parts found in budget units.
• Prioritize sound insulation if your kitchen is open to living spaces - it makes a big quality-of-life difference.
• Pick your feed type deliberately: continuous feed is faster and more common; batch feed is safer and needs no wall switch.
• Check the mount and the cord: twist-and-lock mounts and pre-attached cords make DIY installation far easier, especially as a like-for-like swap.
• Read the warranty as a durability signal: longer coverage usually tracks with better internals.

Our final take

Most people should buy the InSinkErator Evolution 1 HP: it’s quiet, powerful, and built to last, and it’s the disposal you’ll forget you own - which is exactly what you want. Budget-minded buyers who don’t mind noise get nearly the same grinding for less with the Waste King L-8000, our runner-up. Choose the batch-feed Moen GXB75C only if safety or a switch-free install outranks workflow speed for your home. And whatever you do, resist defaulting to the Badger 5 just because it’s cheap and everywhere - its galvanized parts, weak motor, and short life make it the classic false economy of this category.
