The Top 5 Small Dishwashers for Tiny Kitchens (Tried & Tested)

If you have a small kitchen, you know the struggle: dirty dishes pile up fast, counter space is precious, and squeezing in a full-size dishwasher? Not happening.

That’s where compact dishwashers come in.

I’ve personally tested several mini dishwashers, from portable countertop models to built-in slimline options, and let me tell you – these little machines are game changers.

They clean just as well as full-size dishwashers while using way less water and energy.

In fact, ENERGY STAR certified dishwashers, including compact models, use less than half as much energy as washing dishes by hand and save 8,400 gallons of water each year.

Are Small Dishwashers Any Good?

Absolutely! A lot of people think smaller dishwashers don’t clean as well, but that’s not true. You just need to pick a good one (which I’ve done for you!).

I’ve found that slimline dishwashers (18 inches) and countertop dishwashers can handle daily loads just fine. Some even have extra perks—like fruit-washing programs, air drying, and baby bottle sanitization.

👉 In a hurry?

Here’s a short comparison table. Below you’ll find the pros and cons of each mini dishwasher.

Small Dishwasher Dimensions

Dishwashers come in a variety of dimensions – the standard full-size dishwasher size is 24 x 35 inches.

Small dishwashers are defined as smaller than 24 inches wide.

They can be built into cabinets, and attached to the sink via hoses, and there are countertop models (table dishwashers) as well.

Most Slimline dishwashers measure up to 18 inches in width.

The smallest dishwashers are 16-inch dishwashers.

You can also go for under-sink, in-sink, and single-drawer versions that come in varying dimensions.

The Top 5 Compact Dishwashers (Countertop/Slimline)

There are different types of compact dishwashers:

• Built-in (cabinets)
• Countertop (portable/table dishwashers)
• Under the sink
• Freestanding

We know how challenging it can be to find the right kitchenette dishwasher for small spaces.

The great news is:

We’ve done all the research for you (and us), and below you’ll find the 5 best space-saving dishwashers on the market.

1. HAVA Portable Dishwasher – Best Table Dishwasher

VIEW ON AMAZON $290

$269 AT HAVA

I was skeptical at first, but this little powerhouse surprised me.

Unlike most countertop dishwashers that need to be hooked up to the faucet (which is annoying), the HAVA has a built-in 5-litre water tank, so you can just fill it up and press start.

And if that’s not enough, the HAVA Countertop dishwasher is pretty enough to leave out on the counter or table (with its see-through door and blue LED light to watch the cleaning) and is big enough for 12-inch dinner plates!

This practical apartment-size dishwasher requires no assembly, and once you’ve filled up its 5-liter tank, you are ready to go.

Choose from 5 wash programs (Normal, Speed (40 minutes), Soft, Baby Care, and Fruit), and after 2 hours, your dishes come out fully clean and dry, without soap spots or leftover food.

And, this one is so quiet you’ll probably forget you turned it on for the first time.

The Babycare program sanitizes baby bottles using steam, and you also get a fruit basket to wash your fruit with the fruit wash program.

We tested the HAVA with the normal load program (which takes a little over 2 hours) and found that the silverware and other items were thoroughly cleaned with no residue from the detergent tablet, and even a very dirty plate came out perfectly clean. 

Pros

• Very quiet – won’t interrupt those important kitchen conversations 😉
• Doesn’t require a water source or hookup
• Sanitize option in the baby care program
• A leak protection mechanism that prevents water damage

Cons

• Requires filling it 3 times with a 1.8-liter pitcher (included), sometimes it’s hard not to miss the mark without some splashes
• You’ll need to run the exit hose to the sink below the dishwasher
• You still have to hand-wash your pots and pans – that won’t fit inside.

Available on Amazon ($269)

If you want a similar size dishwasher but with 6 wash programs (and an air freshener program to speed up drying), check out the Comfee Countertop Dishwasher instead.

2. Danby Compact Dishwasher – Best Countertop Mini Dishwasher

VIEW ON AMAZON $324

This one is perfect for small apartments. It fits right on the counter, holds more dishes than the HAVA, and is super easy to set up (it literally took me 5 minutes).

The Danby small countertop (& portable) dishwasher has a quick-connect assembly that is compatible with most kitchen faucets, and no tools are needed for assembly.

With the Danby compact dishwasher, you get everything from an impressive 6-place setting capacity to 6 different wash cycles.

It fits perfectly on the counter next to the sink, and it’s so effective that we didn’t need to wash anything for the second time for all dishwasher-safe dishes.

Pros

• Energy-efficient – uses only 3.1 gallons per cycle (way less than handwashing!)
• Simple setup – just connect it to your faucet.
• Quieter than expected – doesn’t make much noise.
• The controls are user-friendly.
• Does not require any extra tools for assembly
• Seamless digital display, just 4 small, white, in-keeping buttons

3. Frigidaire 18″ Built-In Dishwasher – Best Built-In 

VIEW ON AMAZON $657

If you’re looking for a permanent solution and have space for a built-in unit, this is hands-down one of the best slimline dishwashers.

It’s got a stainless steel interior, a heated drying system, and 8 place settings (great for small families!).

The Frigidaire offers 5 wash cycles, a 24-hour delay start, easy-to-use electronic controls, and a heated drying system, and is a highly efficient cleaner.

A powerful yet time and money-saving dishwasher from a well-known American brand.

Pros

• Super durable – the stainless steel tub won’t rust.
• Sanitize setting – great for deep cleaning.
• Adjustable racks – fit taller plates and cups.

Cons

• The hookup kit is not included (you’ll have to buy it separately).
• Louder than some others – 58 dB noise level.

Available on Amazon ($657)

4. Danby Portable Dishwasher – Best on Wheels

It uses up to 3.5 gallons of water per wash and offers 6 wash cycles, including intensive, economy, normal, glass, soak, and rapid.

Pros

• Big capacity – holds way more dishes than a countertop unit.
• Water-efficient – only uses 3.5 gallons per cycle.
• Easy to move – rolls into storage when not in use.
• Easy hookup, takes a few seconds to connect.

Cons

5. Edge Star Dishwasher  Most Energy Efficient

The Edge Star fits under most kitchen cabinets and most under-the-sink spaces as well, and comes with a drain hose that you would place in the sink for it to drain.

It requires no permanent setup (it comes with a quick-connect adapter that fits standard-sized kitchen faucets) and is super easy to operate.

The Edge Star includes essential accessories: a dish rack, cup shelf, and cutlery basket – all you need to organize your dishes and utensils optimally.

Pros

• Saves $$$ on water & electricity.
• Has a built-in rinse aid dispenser (no water spots!).
• It can reach 149°F to kill bacteria.
• Highly rated by Amazon buyers

Cons

• If you don’t screw the hoses on properly, it might leak (so be careful during setup!).

Available at Walmart ($299)

What is the Smallest Dishwasher You Can Find?

The smallest countertop dishwashers can be placed on your countertop next to your sink. They don’t require any plumbing installation and can be hooked up to your faucet with an adapter hose.

The smallest dishwasher on the market is the KAPAS Portable Countertop Dishwasher with 6 Programs and a 3-cup Water Tank (16″D x 16″ W x 17.5″ H).

VIEW ON AMAZON $288

The Kapas takes up minimal counter space and is lightweight (around 26.4 lbs), making it easy to move or store.

You can choose to fill the built-in 3-cup water tank or connect it directly to your faucet for continuous water flow.

It offers 5 wash cycles (Standard, Quick, Strong, ECO, Fruit) for different cleaning needs.

The high-temperature option can help sanitize dishes and eliminate bacteria, and the air-dry function helps dishes dry completely.

The second smallest dishwasher on the market is the HAVA R01 Compact Countertop Dishwasher, reviewed at the beginning of the post.

At 16.86” x 16.75” x 18.05” (L/W/H), the HAVA compact dishwasher is ideal for small kitchens or apartments with limited space, and we like the sleek and modern design.

How Do You Choose a Compact Dishwasher?

1. Size and Fit – Make sure the height of the countertop dishwasher fits between your countertop and upper cabinets.
Consider the width and depth to make sure it fits your kitchen.

2. Capacity – Look for the number of place settings the dishwasher can accommodate, typically ranging from 4 to 6 place settings.

3. Ensure the interior dimensions fit your typical dish sizes and quantities.

4. Performance and Features – check for features like energy efficiency, wash cycles, drying performance, and noise level.

5. Look for models with certifications like Energy Star to ensure energy and water savings.

6. Portability and Installation – Check if you need a freestanding, built-in, or portable countertop model based on your kitchen setup.

7. Consider if the dishwasher requires a water hookup or can operate with a self-contained water tank.

Which Dishwasher Uses the Least Amount of Water?

Here’s a comparison of the water usage of all 5 compact dishwashers on this list:

As you can see, the Faberware countertop dishwasher uses the least amount of water per cycle (only 1.3 gallons).

The Frigidaire 18-inch built-in dishwasher uses the most – 4.2 gallons per cycle.

Why Are 18-inch Dishwashers More Expensive?

You may expect to pay a little less for a smaller dishwasher, but feature-wise, they are in line with the standard-size ones, and you buy them to save space while having the same efficiency.

Also, slimline dishwashers are not as common as the standard 24-inch models, which means less competition in the market and higher prices because they are less produced.

Can You Put a Countertop Dishwasher in a Cabinet?

No, you cannot put a countertop dishwasher in a cabinet. It is not intended or designed to be fixed inside a cabinet or under the counter.

It can only be used and installed as instructed, mainly because the heat needs to be exhausted as it was designed.

In some cases, you can put it in a cabinet if there is enough clearance around the dishwasher for proper ventilation and the cabinet is strong enough to support its weight.

How Long Does a Small Dishwasher Take to Run?

The standard run time of dishwashers is up to 2 hours.

It can also sometimes be less, or more, according to the model type.

On some models of dishwashers, you can even see the timer display.

Is an 18-inch Dishwasher Too Small?

Although 18-inch dishwashers are relatively smaller, they can take care of all the functions that full-sized dishwashers can.

The only difference is that these dishwashers can take up fewer loads of dishes at a time while also taking up less space in the kitchen.

How Far Can a Dishwasher Be Away From the Sink?

Most dishwashers come with a drain hose around 6 feet long. Manufacturers typically allow for extensions to a maximum length of 10 to 12 feet.

Exceeding this can cause drainage issues.

Similar to the drain hose, standard dishwasher supply lines are around 6 feet long.

Extending these is also possible, but consult a plumber to ensure proper installation.

While you can extend these hoses, we recommend keeping the dishwasher close to the sink for convenience and to minimize the need for extensions.

In kitchen design, there’s a concept called the working triangle, which emphasizes efficiency by placing the refrigerator, stove, and sink close.

A dishwasher far from the sink can disrupt this workflow.

Overall, while there’s no hard and fast rule, keeping the dishwasher close to the sink is ideal for functionality and avoiding complex plumbing modifications.
