For a small kitchen space, a compact or slimline dishwasher (18 inches) is the best way to get your dishes done for you while saving on your electricity and water bills.

Small (apartment-size) dishwashers save space, are energy efficient, and use less water – when taking care of those mountains of dirty plates after mealtimes.

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. Farberware Portable Dishwasher – Best Table Dishwasher

While most apartment-sized dishwashers require hooking up to a faucet (which means you can’t use the sink for hours) and others are complicated to install, the Faberware portable 17″ dishwasher has a built-in five-liter tank and doesn’t require a water source or a hookup.

(But it still offers this option if you want)

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

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.

The Faberware maxes out at about 2 glasses, 8 pieces of flatware, and one storage container – it won’t be enough for a household with more than 2 people.

We tested it with the normal load program (which takes s 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 – a true table dishwasher
• Sanitize option in baby care program
• Leak protection mechanism that prevents water damage

Cons

• requires filling it 3 times with a 1.8-liter pitcher (included), sometimes it’s hard to not 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 ($422)

👉 Farberware Alternative

Consider the Comfee Countertop Dishwasher, which is the same size and capacity and also doesn’t require hookup but has 6 programs (with an air freshener program to speed up drying).

However, it is a bit noisier (58 dB) than the Faberware (51 dB).

2. hOmeLabs Compact Dishwasher – Best Countertop Mini Dishwasher

The hOmeLabs small countertop (& portable) dishwasher is great for small kitchens or office spaces.

This lightweight dishwasher has a six-place setting rack, and no tools are needed for assembly – thanks to the quick connect assembly with accessories included.

Cons

5. Edge Star Dishwasher  Most Energy Efficient

It 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 (comes with a quick-connect adapter that fits standard-sized kitchen faucets) and is super easy to operate.

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 water usage of all 5 compact dishwashers in 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 featurewise, 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 on 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.

What is a Portable Dishwasher?

A countertop or portable dishwasher has a hose that can temporarily attach to your kitchen sink’s faucet.

However, this will only work if the sink faucet contains a threaded faucet spout.

For instance, faucets that contain built-in sprayers do not possess threaded faucet spouts.

These dishwashers are an excellent choice if you wash small loads of dishes daily.

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.
