Garbage Disposals
The best garbage disposals for deep sinks
Deep bowls are the default now, and they eat the space a disposal needs. Overall height is the specification that decides this, not horsepower.
Disclosure: we earn a commission if you buy through the Amazon links on this page, at no extra cost to you. Commission never decides a verdict or a ranking position — read our editorial policy and affiliate disclosure.
How we assessed these: we compared published manufacturer specifications for the named model numbers, read from each maker's own product page or specification sheet and linked at every figure. We have not installed or tested these disposals and we do not own them. No manufacturer publishes a comparable decibel rating for a domestic disposal and no independent laboratory measures them, so no noise figure appears anywhere on this page.
Short answer
For a deep sink, the InSinkErator Evolution .75HP is the unit to fit: at 12.25 inches overall it is only three-quarters of an inch taller than the shortest disposal InSinkErator makes, while still giving you 3/4 HP and three grind stages. If even that will not clear, the Badger 5 at 11-1/2 inches is the shortest option here.
Sink bowls have got deeper. Ten inches is now ordinary — the Kraus KHT300-33 publishes a 10-inch bowl, the Kraus Kore KWU110-30 the same — where a kitchen built twenty years ago had seven or eight. Every inch of that extra depth comes out of the cabinet below, and the cabinet below is where the disposal, the trap and the trap arm all have to coexist.

The sum that decides it
Work from the top down, in this order, and you will know the answer before you buy anything:
- Bowl depth, from the sink rim to the drain opening. Published by every sink maker.
- Disposal overall height, from the mounting flange to the bottom of the motor housing. Published by most disposal makers — but not all, which matters below.
- Discharge height, the distance from the sink rim down to the disposal's side outlet. This is where the waste leaves the unit and it must sit above the trap.
- Trap arm height, the center of the stub-out in the cabinet wall. This is fixed unless you open the wall, and it is the number that actually constrains you.
The disposal's discharge has to be high enough to drop into the P-trap and run downhill to the trap arm. A deep bowl pushes the whole stack down. A tall disposal pushes it down further. Put a 10-inch bowl and a 13-inch disposal over a high trap arm and the discharge ends up at or below the stub-out, which no amount of fittings fixes properly.

|---|---|---|---|---|
| InSinkErator Badger 5 | 11-1/2" | 1/2 HP, 1725 rpm | One | Not published |
| InSinkErator Evolution .75HP | 12.25" | 3/4 HP Dura-Drive | Three-stage MultiGrind | Not published |

Heights are each manufacturer's own published overall height, linked below. Waste King does not publish an overall height for the L-8000 on the specification sheet we read, so this table says so rather than estimating one - which is a genuine problem if clearance is tight, because you cannot plan around a figure that does not exist. No decibel rating appears here because no maker publishes a comparable one.

1. Best overall
InSinkErator Evolution .75HP
InSinkErator · Best for households of three to five
The disposal we would fit in most houses. Three-quarters of a horsepower with three-stage grinding and stainless grind components is the point on the range where fibrous waste stops being a gamble, and SoundSeal makes it noticeably quieter than a Badger. The nine-year in-home warranty is the longest of any InSinkErator continuous-feed unit we checked.
Published specifications
- Motor
- 3/4 HP Dura-Drive induction source
- Grind stages
- Three-stage MultiGrind source
- Grind components
- Stainless steel source
- Overall height
- 12.25" source
- Sound
- SoundSeal — quieter than a standard disposal source
- Septic
- Safe for properly maintained septic tanks source
- Warranty
- 9-year We Come to You limited service warranty source
What works
- Three grind stages and stainless components — the two specs that decide whether fibrous scraps jam
- Only three-quarters of an inch taller than a Badger 5, so it fits most cabinets that took one
- Nine-year in-home warranty, which is a real statement about expected service life
- EZ Connect cord and hardwire adapter in the box, so it suits either wiring situation
What does not
- InSinkErator publishes no decibel figure, and neither do we — SoundSeal is a comparison, not a measurement
- 3/4 HP still stalls on bones and fruit pits; no domestic disposal is a bone grinder
- Chamber capacity is not published for this model
Skip it if
Skip it if you are one or two people who scrape plates and little else — you would be paying for capability you will not use.

2. Shortest unit here
InSinkErator Badger 5
InSinkErator · Best for one or two people, tight cabinets
The baseline every other disposal is measured against, and an honest buy for a small household as long as you know what you are getting: half a horsepower, one grind stage, and galvanized steel grind components rather than stainless. It is short at 11-1/2", which is often the deciding factor in a shallow cabinet.
Published specifications
What works
- Shortest unit here at 11-1/2" — it fits cabinets a 1 HP unit cannot
- Cheapest route to a working disposal from the brand with the best parts availability
- Genuinely adequate for soft scraps: peelings, plate scrapings, coffee grounds
- In-home warranty service rather than ship-it-back
What does not
- Galvanized grind components, not stainless — this is the real difference between Badger and Evolution
- One grind stage, so fibrous waste like celery and corn husks is where it stalls
- No sound insulation of any kind, and the product page makes no noise claim
Skip it if
Skip it if you cook for four or more, or if anything fibrous goes down the drain. Buy 3/4 HP with three stages instead.

3. Lightest to lift into place
Waste King Legend L-8000
Waste King · Best for value 1 hp with a cord fitted
A different engineering answer to the same problem: a 2800 rpm permanent-magnet motor instead of a slower induction motor with more grind stages. High speed rather than high torque, in a lighter and narrower body, with a 20-year warranty and a factory-fitted power cord. This is the value 1 HP unit.
Published specifications
What works
- 2800 rpm is the highest motor speed here; speed does the work that extra grind stages do on an InSinkErator
- Under 12 lb, which makes a one-person overhead installation genuinely possible
- Power cord pre-attached — no separate cord kit, no wiring
- A 20-year limited warranty at this price is unusual
What does not
- High-speed permanent-magnet motors are louder in character than slow induction motors, and no party publishes a comparable decibel figure
- Single-stage grinding, so output fineness is not comparable to a three-stage MultiGrind
- Waste King's parts network is smaller than InSinkErator's
Skip it if
Skip it if grind fineness matters — on a septic system, for instance, where finer output is the whole point. Three stages beat high rpm there.

4. Most power, if you have the room
InSinkErator Evolution 1HP
InSinkErator · Best for large households, frequent jams
The full-horsepower option, and the only one here with a published jam-breaking mechanism: the Jam-Sensor circuit raises motor torque by 500% to clear a stall instead of tripping the reset. If you have a large household and a history of resetting a disposal weekly, this is what that problem costs to solve.
Published specifications
- Motor
- 1.0 HP, single phase, 120 V, 60 Hz, 1725 rpm source
- Grind stages
- Three-stage MultiGrind, against one on a standard disposal source
- Jam handling
- Jam-Sensor circuit increases motor torque 500% to break jams source
- Sound
- SoundSeal, plus the Quiet Collar sound-reducing baffle source
- Overall height
- 13" source
- Weight
- 23.0 lb shipping weight source
- Warranty
- 7-year parts and in-home service source
What works
- Jam-Sensor is the one published feature that addresses the most common disposal complaint
- The Quiet Collar baffle is included rather than sold separately, and the baffle is most of the perceived noise fix
- 1 HP with three stages handles the fibrous waste that stalls half-horsepower units
- InSinkErator publishes a full spec sheet including amperage and RPM
What does not
- 13 inches tall and 23 lb — the largest unit here, and the most likely to foul a shallow cabinet or a P-trap
- Seven-year warranty is shorter than the 3/4 HP Evolution's nine
- 1 HP does not make it a bone grinder; the failure point just moves
Skip it if
Skip it if your cabinet is shallow or your trap arm sits high — measure the 13-inch height before buying horsepower you cannot fit.

Why the shortest unit is not automatically the right one
The Badger 5 is the shortest disposal here and the obvious answer to a clearance problem, but it costs you something real. It is 1/2 HP with one grind stage and galvanized steel grind components with stainless swivel lugs — not the stainless grind components of the Evolution range. That is the actual difference between the two families, and it shows up on fibrous waste: celery, corn husks, artichoke, onion skins, where a single stage lets material bridge rather than break down.
Three-quarters of an inch is what the Evolution .75HP asks you for in exchange for three stages, stainless components, SoundSeal insulation and a nine-year in-home warranty against the Badger's five. If you have that three-quarters of an inch, take it. 1/2 HP vs 3/4 HP is the step argued out in full, and the garbage disposal horsepower guide is the scale.
The shallow-sink alternative
If you are buying the sink at the same time, you have a second lever, and it is often the better one. The Kraus KWT310-33/5.5 publishes a 5.5-inch bowl — ADA-compliant depth — in a 33 by 22 footprint, and it still carries a workstation ledge so the cutting board and drying rack recover the prep space the shallow bowl costs. A 5.5-inch bowl leaves four and a half inches more cabinet height than a 10-inch one, which converts a clearance problem into a non-problem.
The Kraus Premier KTM100-33 is the other route: 18-gauge, a 7-1/2 inch bowl, the depth older kitchens were plumbed around. How deep should a kitchen sink be sets out the depth trade-off, and sink sizes and cabinet fit does the cabinet arithmetic.
Weight, because somebody has to hold it up there
This is the specification nobody considers until they are lying in a cabinet. Fitting a disposal means holding the unit overhead with one hand and turning a mounting ring with the other. The Waste King L-8000 publishes 11.94 lb; InSinkErator publishes 23.0 lb shipping weight for the Evolution 1HP. That is close to double, and in a deep cabinet under a deep sink it is the difference between a one-person job and a two-person one.
The Waste King also arrives with its power cord fitted, which removes a wiring step. How to install a garbage disposal is the full procedure, and do garbage disposals come with a power cord covers which do and which do not.
Which one to buy
- Buy the Evolution .75HP if you have 12.25 inches of clearance. It is the best combination of short, capable and warranted here.
- Buy the Badger 5 if you have 11-1/2 inches and no more. One grind stage and galvanized components are the price, and it is an honest buy for a small household.
- Buy the Waste King L-8000 if the lift is the problem — under 12 lb with the cord fitted — accepting that Waste King does not publish an overall height.
- Buy the Evolution 1HP only if you have measured 13 inches plus trap clearance. Jam-Sensor is the best jam-handling specification here, and the body is the largest.
- Avoid the Cover Control in a tight cabinet. At 14.95 inches it is the tallest unit in this registry.
What to take away
- Overall height, not horsepower, is the specification that decides a disposal in a deep-sink cabinet.
- The real constraint is the trap arm stub-out, which is fixed unless you open the wall.
- Published heights here run from 11-1/2 inches to 14.95 inches - a three-and-a-half-inch spread.
- Waste King does not publish an overall height for the L-8000, which is a planning problem in a tight cabinet.
- A shallower sink frees more clearance than any disposal choice can.
- Weight matters because you fit a disposal overhead, one-handed - 11.94 lb against 23 lb is a real difference.

Common questions
- What is the best garbage disposal for a deep sink?
- The InSinkErator Evolution .75HP, on published specifications: 12.25 inches overall, which is three-quarters of an inch taller than the shortest unit InSinkErator makes, with 3/4 HP, three grind stages and a nine-year in-home warranty. Where even that will not clear, the Badger 5 at 11-1/2 inches is the shortest here.
- How much space do you need under a sink for a garbage disposal?
- Enough for the unit's published overall height plus room for the P-trap below its discharge, measured down from the sink rim and against the height of the trap arm in the cabinet wall. Published heights in this registry run from 11-1/2 to 14.95 inches, so the answer depends entirely on the unit.
- Will a garbage disposal fit under a 10-inch deep sink?
- Usually, but it depends on your trap arm height rather than the sink. A 10-inch bowl plus a 13-inch disposal pushes the discharge low, and it has to stay above the stub-out to drain. Measure from the rim to the stub-out before choosing a unit.
- Is a shorter garbage disposal less powerful?
- In this registry, yes - the shortest unit is also the 1/2 HP single-stage one with galvanized grind components. The 3/4 HP three-stage Evolution is only three-quarters of an inch taller, so the trade is much smaller than the price difference suggests.
