Small Dishwasher Dimensions

Dishwashers come in a variety of dimensions. The standard dishwasher size is 24 x 35 inches. Small dishwashers are defined as smaller than 24 inches wide. They can be built into cabinets, 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.

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

faberware small portable countertop dishwasher
Faberware portable dishwasher – no hookup necessary – view on Amazon
  • Size: 17.3 x 16.5 x 17.3 inches
  • Wash Cycles: 5 wash cycles – normal/rapid/babycare/fruit wash/glass)

While most condo-size 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.

And if that’s not enough, the Faberware 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!

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/rapid – 40 minutes/ baby care/glass/fruit wash), 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.

The only con we’ve found is that you still have to hand wash your pots and pans – that won’t fit inside. It maxes out at about 2 glasses, 8 pieces of flatware, and one storage container. It won’t fit a household with more than 2 people.

👉 Faberware Portable Dishwasher 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 babycare program
  • Leak protection mechanism that prevents water damage


  • requires filling it 3 times 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

👉 Faberware Alternative

Compact Dishwasher FAQ

Can You Put a Countertop Dishwasher in a Cabinet?

No, you cannot. A countertop dishwasher 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 to.

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 in case 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 in size, 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.
