How to choose a small dishwasher?

When it comes to choosing a dishwasher, the important features are mainly the same, whether you go with a small 18-inch or full-size design. Let’s take a look at what you’ll want to look for and the most important features you’ll want in a compact dishwasher.

Quietness

Quiet operation has quickly become an essential feature in any quality dishwasher. Usually, the dishwasher is installed in one of the most-used areas of the house. Loud operation can disrupt conversations and cause uncomfortable situations. So how do 18-inch compact models stack up with the quietest full-size designs?
Fortunately, they stack up pretty well. Recent models of 18-inch dishwashers are receiving quietness ratings comparable to some of the quietest full-size models available. But when you start getting into decibel levels with numbers and figures, it can be a bit confusing. So let’s take a look at some reference points you can use to understand just how quiet your dishwasher will be.

The best dishwashers on the market achieve quietness levels at around 45dB, which is roughly the volume of a quiet library. A normal conversation is about 60dB in volume, while the sound of light traffic outside your window is usually around 50dB. Designer Appliances recommends anything between 44-48dB, as this will be quiet enough to keep from interfering with your day-to-day activities around the appliance.

Water Softeners for Spotless Results

Designed to help combat water spots, built-in water softeners remove minerals from the water that can be hard on dishes overtime. If your neighborhood or area has hard water, you may want to consider a model with a built-in water softener.


ADA Height for Shorter Countertops

ADA stands for “Americans with Disabilities Act.” It signifies products and environments that are designed to be easy for disabled individuals to use and operate.

In the context of ADA compliant dishwashers, the certification says more about dishwasher height than anything. Raised floors or countertops that are not built with regular standards in mind pose a challenge for home owners for dishwasher fit. Fortunately, nearly all compact dishwashers are ADA compliant to help alleviate this problem.

ADA-Compliant

Since there are not as many 18-inch units (compared to their full size cousins) manufacturers pack more in them. Such as ADA compliance, so that they fit universally.


Pricing

Prices for compact dishwashers can range anywhere from $600 to $1,500. You can expect higher prices for high-end features like quietness, a flexible third rack, or water softener. If you’re looking for an ultra-quiet dishwasher, anything under 48dB, you can expect a price of $700 or more. Add a water softener and you’ll see prices rise to $750 and above, and you can add a panel-ready design to blend seamlessly with your kitchen for a bit higher price tag.

Considering how popular compact, 18 inch dishwashers have become, the market has become saturated with a wide range of brands, styles and designs. Fortunately, we’re here to help you wade through the many products to find the best options for you.
