What You Should Know About 18 Inch Dishwashers - ESPECIALLY IF YOU'RE A FIRST-TIME BUYER!

These dishwashers are smaller, but they're usually not cheaper than a standard 24" wide model. Most are around $700 and up. Mainstream brands like Electrolux, GE Appliances, Whirlpool, and Frigidaire make them, as well as smaller brands like Danby and Summit.

The external height of an 18-inch dishwasher is also slightly shorter on average than for a 24-inch model. A full-size built-in dishwasher is usually about 33.9" tall, while many 18" dishwashers are between 32-33" tall. This is convenient for issues like shorter countertops or raised sub-floors that limit the vertical space for installation. However, with tall countertops, you may see a gap between the dishwasher and the floor if the kickplate isn't tall enough to conceal it.

Rack spacing can be an issue with these smaller models, both between racks and within them. If you have "chunky" earthenware or stoneware plates and bowls, tine spacing and angles are of particular concern. You'll also want to consider the diameter of your full-sized plates and whether they'll fit in the lower rack without catching on the upper wash arm.

Cycle times for dishwashers have gotten longer as they have become more energy efficient. You can expect a typical wash cycle to last about 2 hours, just like with a standard-size dishwasher. This can be inconvenient if you have a lot of dishes to wash.

They work best for small households of 1-3 people, or people with light dishwashing needs. Many 18" dishwashers claim to have an 8-10 place setting capacity*, while a full size dishwasher will usually fit 12-14. Whether you can actually fully utilize the claimed capacity will vary because cups, bowls, etc are not standard in size and thickness. If you have smaller cup diameters and porcelain plates and bowls, you'll have better luck.

*You might be asking: What the heck is a place setting? One "place setting" equals:

  • 1 dinner plate

  • 1 smaller snack plate

  • 1 saucer

  • 1 bowl

  • 1 coffee cup

  • 1 drinking glass

  • 1 knife

  • 2 teaspoons

  • 2 forks

5. Frigidaire FFBD1831US - 52 db - $799

Last but not least in our reviews of the best 18-inch dishwasher models is the Frigidaire FFBD1831US, a front control model with a pocket handle available at $799 in stainless steel and at $749 in black or in white. While it's not as quiet as the other models in this post, with its 52-decibel operation, it's still quieter than older dishwashers. It's also ADA compliant.

For its price, you get multiple cleaning cycle options you're familiar with, like Heavy Wash, Quick Wash, and Rinse Only. This model is Energy Star rated and has an Energy Saver program. It also features the NSF-certified Sanitize option that eliminates 99.9% of common household bacteria and the heated drying system helps dry your dishes more quickly. For a thorough clean, you can rely on its dual spray arm system. Cycle status indicators let you know when the dishwasher is in delay, wash, dry, and clean mode.

There are many positive customer reviews. One of the complaints people have had with this model are that it doesn't dry well despite the heated drying, and some people also had issues with the model leaking. Although the happy reviews outweigh the unhappy ones, we think the other models on our list are worth a second look.
