Limited space under the kitchen sink can make choosing a garbage disposal surprisingly difficult. A full-size unit may interfere with plumbing, storage or other under-sink equipment, particularly in apartments and smaller kitchens.
Fortunately, you don’t necessarily have to sacrifice performance to save space. Several compact garbage disposals combine smaller dimensions with enough power for everyday household food waste.
In this guide, we’ve compared 7 of the smallest garbage disposals to help you find a model that suits your available space, household size and typical kitchen use. If you’re still comparing overall performance, features and value, our guide to the Best Garbage Disposals can help you narrow down the strongest options beyond compact size alone.
Before choosing one, remember that height isn’t the only measurement that matters. Motor power, width, mounting system, noise and the position of your existing plumbing should all be considered.

What counts as a small garbage disposal?
There isn’t an official size that defines a “compact” garbage disposal. For this guide, we’re primarily looking at models designed to take up less under-sink space than larger or heavily insulated disposals.
Compact models commonly have:
- A shorter overall height
- A relatively narrow body
- Motors around ⅓ HP to ¾ HP
- Less bulky sound insulation
- Designs intended for apartments, small households or tight cabinets
However, height alone doesn’t determine whether a disposal will fit. You also need enough room for the drain connection, plumbing and dishwasher connection (if applicable).
Before purchasing any disposal, measure your available under-sink space and compare it with the manufacturer’s current dimensions.
What Size Disposal Do You Need?
Compact doesn’t necessarily mean underpowered. The right horsepower depends more on how many people use the kitchen and how much food waste you process than the physical size of your cabinet.
As a general guide:
⅓ HP: Best suited to very light or occasional use.
½ HP: A practical starting point for smaller households and everyday food scraps.
¾ HP: Offers additional grinding power for households that use their disposal more frequently.
1 HP and above: Better suited to heavier use, although these units are often physically larger.
If cabinet space is extremely limited, finding the right balance between motor power and physical dimensions becomes particularly important.

Our compact pick: If under-sink height is your biggest concern, the KitchenAid KCDB250G and InSinkErator Badger series stand out for their short profiles. However, dimensions aren’t the only consideration. Motor power, width, plumbing position and installation requirements should also influence your choice.
InSinkErator Badger 1 — Best for Very Light Use
If keeping the disposal as compact as possible is your main priority, the InSinkErator Badger 1 is one of the smallest options in the Badger range.
At approximately 11½ inches high with a ⅓ HP motor, it takes up considerably less vertical space than many larger, more powerful garbage disposals. That can make it particularly useful in small kitchens, apartments or cabinets where plumbing and storage leave little room to work with.
The trade-off is power. A ⅓ HP motor is better suited to light and occasional use rather than households that regularly send larger amounts of food waste through the disposal.
Key Specs
- Motor: ⅓ HP
- Height: approximately 11½ inches
- Feed type: Continuous feed
- Best for: Small households and light use
- Main advantage: Compact dimensions
Pros- Very compact 11½-inch height
- Simple design
- Suitable for light household use
- Doesn’t require the extra vertical space of larger models
Cons
- Only ⅓ HP
- Not my pick for frequent/heavier use
- Fewer premium features than more expensive models
Things to Consider
The Badger 1 makes sense if space and basic functionality matter more than grinding power. However, if you use your disposal frequently, stepping up to a ½ HP model such as the Badger 5 may provide a better balance between size and everyday performance.
Verdict: A good choice for very light use where under-sink space is particularly limited.
InSinkErator Badger 5 — Best Compact All-Rounder
For many smaller households, the InSinkErator Badger 5 offers a better balance between compact dimensions and everyday grinding power.
Like the Badger 1, it’s approximately 11½ inches high, but its ½ HP motor gives it additional capacity for regular household use without requiring significantly more vertical space.
That combination makes the Badger 5 particularly appealing if you’re working with a small cabinet but don’t want to drop all the way down to a ⅓ HP disposal.
Key Specs
- Motor: ½ HP
- Height: approximately 11½ inches
- Feed type: Continuous feed
- Best for: Small households and everyday use
- Main advantage: Compact size with more usable power
Pros
- Compact 11½-inch height
- ½ HP motor offers a good balance of size and everyday performance
- Suitable for most small households
- Simple, straightforward design
- More capable for regular use than the ⅓ HP Badger 1
Cons
- Not as powerful as ¾ HP models
- Limited premium noise-reduction features
- May not be ideal for larger households or frequent/heavy use
Things to Consider
Although the Badger 5 is compact, it’s still an entry-level disposal rather than a premium, heavily insulated model. If noise reduction or handling more frequent food waste is important, you may prefer a more powerful option.
Verdict: One of the strongest choices for shoppers who want a small garbage disposal without sacrificing too much everyday performance.
InSinkErator Badger 5XP — Best for More Grinding Power
Need more power but still don’t want a huge unit underneath the sink? The InSinkErator Badger 5XP is worth considering.
Its ¾ HP motor provides more grinding power than the Badger 1 and Badger 5, while its approximately 12⅝-inch height keeps it relatively compact compared with many larger-capacity disposals.
That makes it particularly useful for households that use their disposal frequently but still have limited cabinet space.

- Suitable for households that use their disposal regularly
Cons
- Slightly taller than the Badger 1 and Badger 5
- Takes up more under-sink space than the smaller Badger models
- Lacks some of the premium sound-reduction features found in higher-end disposals
Things to Consider
The extra power comes with a slightly larger footprint than the Badger 1 and Badger 5. If every inch of under-sink height matters, one of the shorter ½ HP models may be a better fit.
Before purchasing, always compare the complete manufacturer dimensions with your available cabinet space rather than relying on height alone.
Verdict: A strong option if you want ¾ HP performance without moving to an especially bulky garbage disposal.
KitchenAid KCDB250G — Best for Tight Under-Sink Spaces
The KitchenAid KCDB250G is a particularly interesting option for kitchens where vertical space underneath the sink is limited.
At approximately 11⅜ inches high, it’s one of the shortest models in our comparison. Despite its compact dimensions, it has a ½ HP motor, giving it a useful balance between space-saving design and everyday grinding performance.
That makes it a good option for smaller kitchens, apartments or cabinets where plumbing, water filters or storage already compete for space.
Key Specs
- Motor: ½ HP

The KitchenAid KCDB250G is one of the strongest choices in this comparison if under-sink height is your main concern. Its combination of an approximately 11⅜-inch body and ½ HP motor makes it particularly appealing for compact kitchens without dropping to a lower-powered ⅓ HP disposal.
Moen GXP50C — Best Lightweight Compact Option
The Moen GXP50C is a good option for shoppers who want a relatively lightweight garbage disposal with enough power for normal everyday kitchen use.
It uses a ½ HP motor and has an overall height of approximately 13⅛ inches. While that makes it taller than the Badger and KitchenAid models above, its relatively narrow and lightweight design can still make it useful where overall under-sink space is limited.
The GXP50C is therefore less about being the absolute shortest disposal and more about providing a compact, lightweight alternative for smaller households.
Key Specs
- Motor: ½ HP
- Height: approximately 13⅛ inches
- Feed type: Continuous feed
- Best for: Everyday use in smaller households
- Main advantage: lightweight, compact design
Pros
- ½ HP motor suitable for everyday household use

- Designed more for normal household use than frequent heavy-duty grinding
Verdict
The Moen GXP50C is worth considering if you want a lightweight, relatively narrow ½ HP disposal and have enough vertical clearance beneath your sink. If height is your biggest concern, however, the shorter KitchenAid KCDB250G or InSinkErator Badger models may be a better fit.
Moen GX50C — Best for Everyday Use
The Moen GX50C is another ½ HP option designed for everyday household food waste. At approximately 13⅜ inches high, it isn’t the shortest disposal in this comparison, but it provides a practical combination of moderate grinding power and a relatively compact design.
For a small household that uses a garbage disposal regularly but doesn’t need the additional power of a ¾ HP model, the GX50C can provide a sensible middle ground.
At approximately 13⅜ inches high, the GX50C is reasonably compact vertically, but it has a wider body than the slimmer Moen GXP50C. That makes it particularly important to measure both the height and width available beneath your sink before buying. If overall cabinet space is very tight, the narrower GXP50C or one of the shorter Badger or KitchenAid models may be a better fit.
Key Specs
- Motor: ½ HP
- Height: approximately 13⅜ inches
- Feed type: Continuous feed
- Best for: Regular everyday household use
- Main advantage: Everyday ½ HP performance with SoundSHIELD sound insulation
Pros
- ½ HP motor suitable for everyday food scraps
- SoundSHIELD insulation helps reduce operating noise

Its 2600 RPM motor also makes it stand out from some of the other compact options on this list. For smaller households wanting a straightforward disposal for regular food scraps, the L-2600 provides a useful combination of speed, power and manageable dimensions.
Key Specs
- Motor: ½ HP
- Motor speed: 2600 RPM
- Height: approximately 13½ inches
- Width: approximately 6¾ inches
- Feed type: Continuous feed
- Best for: Small-to-medium households
- Main advantage: Relatively narrow body with DIY-friendly EZ Mount installation
Pros
- Fast 2600 RPM motor
- ½ HP suitable for normal everyday use
- Relatively narrow 7-inch body
- Continuous-feed operation
- Pre-installed power cord can simplify compatible installations

How to Choose a Compact Garbage Disposal
Finding the smallest garbage disposal isn’t simply about choosing the shortest model. The right unit needs to fit comfortably beneath your sink while still providing enough power for your household.
Here are the main factors to consider before buying.
1. Measure Your Under-Sink Space
Before comparing models, measure the available height, width and depth beneath your sink.
Remember to account for:
- Drain pipes
- Dishwasher connections
- Water filtration systems
- Cabinet shelving
- Any storage you want to retain
A disposal that looks compact on paper may still interfere with your existing plumbing, so always compare your measurements with the manufacturer’s current specifications before purchasing.
2. Choose the Right Horsepower
Compact garbage disposals are available with different motor sizes.
A ⅓ HP disposal can work for very light use, while ½ HP provides a better balance for many smaller households. A ¾ HP model offers additional grinding power for households that use their disposal more frequently.
The goal isn’t necessarily to buy the most powerful unit. It’s to find enough power for your needs without unnecessarily sacrificing under-sink space.
3. Consider More Than Height
Height is important, but don’t overlook width and overall shape.
A slightly taller but narrower disposal may work better around existing plumbing than a shorter, wider model.
The location of the waste outlet also matters because it needs to align appropriately with your drain configuration.
4. Think About Noise
Compact disposals don’t always have the same level of sound insulation as larger premium models.
If your kitchen is open-plan or noise is particularly important to you, compare the manufacturer’s sound-reduction features rather than choosing purely by dimensions.
5. Check the Installation Requirements
If you’re replacing an existing disposal, check whether the new model is compatible with your current mounting and electrical setup. Our How to Replace a Garbage Disposal guide walks through the process step by step.
Changing brands or mounting systems may require additional installation work.
If you’re unsure about the electrical or plumbing requirements, professional installation may be the safer option.
6. Compare the Warranty
Warranty coverage varies considerably between garbage disposal models.
Don’t assume a longer warranty automatically means a better disposal, but it’s worth considering alongside price, motor power and expected usage.
Warranty length can also vary significantly between manufacturers, so it’s worth comparing the Best Garbage Disposal Brands before choosing a model based on size alone.
FAQs
What is the smallest garbage disposal?
There isn’t one universal “smallest” garbage disposal because models differ in height, width and overall shape. In our comparison, some of the shortest options are around 11–12 inches high. The best compact model for your kitchen ultimately depends on the space available around your plumbing.
Is a ⅓ HP garbage disposal powerful enough?
A ⅓ HP disposal can be suitable for very light or occasional use, particularly in a small household. For more regular everyday use, a ½ HP model will generally provide additional grinding capability without necessarily requiring a much larger unit.
Are compact garbage disposals less powerful?
Not necessarily. Some compact models offer ½ HP or even ¾ HP motors. However, higher-powered disposals can sometimes require more physical space, particularly when additional sound insulation is included.
Can I install a compact garbage disposal myself?
Some homeowners can replace an existing disposal themselves, particularly when the new model is compatible with the existing mounting and electrical setup.
However, plumbing or electrical modifications can make installation more complicated. If you’re uncomfortable working with either, consider using a qualified professional.
How much space do I need beneath my sink?
There’s no single minimum because every disposal and plumbing configuration is different.
Measure the available height, width and depth and leave adequate room for the drain connection, plumbing and any dishwasher connection. Always check the manufacturer’s installation dimensions before buying.
Final Verdict
The best compact garbage disposal isn’t necessarily the model with the smallest dimensions. The goal is to find a unit that fits your available under-sink space while still providing enough grinding power for your household.
For very limited spaces and light use, a smaller ⅓ HP model may be sufficient. For many households, a compact ½ HP disposal offers a useful balance between size and everyday performance, while ¾ HP models provide additional power for more frequent use.
Before making your final decision, measure your cabinet carefully and consider the disposal’s height, width, horsepower, installation requirements and warranty.
Choosing based on your actual kitchen setup rather than dimensions alone will give you a much better chance of finding a disposal that fits properly and performs well for years to come.
Once you’ve found a compact model that fits your space, don’t forget to factor installation into your budget. Our Garbage Disposal Installation Cost guide explains what you can expect to pay for DIY and professional installation.
