1 of 2

The demand for small dishwashers significantly increased in the last decade, mostly among urban dwellers. Whether you have a narrow under-counter nook, are trying to save space or adding some convenience to your outdoor kitchen, you might find these narrower 18-inch dishwashers a great solution. Just as 24 inches is the standard width of full-sized dishwashers, 18 inches is standard for narrow dishwashers. The selection among models this size is not vast, but there are several well-known appliance brands that manufacture them (like Danby and Frigidaire). Here are a few things to know before you go out shopping for one:

  1. Price: These dishwashers are smaller, and therefore less expensive. Most 18-inch models cost below $500.
  2. Capacity: Narrow models have room for 6-8 five-piece place settings.
  3. Style: Expect to compromise style for convenience here. 18-inch models will most often have the controls on the front, not hidden. Also, only about half the models on the market have a stainless-steel finish.
  4. Features: Most 18-inch models offer just as many wash cycle options as full-sized dishwashers do. However, they hardly ever offer a sanitizing cycle option.
  5. Noise: Users report that smaller dishwashers are typically noisier than full-sized ones. The data backs this up, as the top 18-inch models average at around 55 decibels, while the average for full-sized models is 49.
  6. Energy: The majority of 18-inch models are Energy Star certified, just like their full-sized counterparts.

These dishwashers receive mixed reviews by users: while some get spectacular ratings, like the Sunpentown 18" Portable Dishwasher, others are just "meh"... or downright awful. Browse through user scores and opinions to find yourself a sure winner.
