An 18-inch dishwasher is the perfect solution for those who are tired of washing dishes by hand but don’t have too much space in the kitchen. These compact dishwashers are highly convenient for small kitchens and some of them are even portable. With a slim build, these appliances are designed to fit into a small space and still do the job of washing a decent number of dishes. For homes with just one or two people, they make more sense than larger dishwashers since you don’t have to wait as long for the dishwasher to fill up before you run it – no more doing dishes by hand because you don’t feel like the dishwasher’s full enough to run without wasting water or energy.
Why Choose an 18-Inch Dishwasher?
No one wants the Sisyphean task of hand-washing dishes day in and day out. But if you don’t have a ton of room in your kitchen or you don’t end up with that many dirty dishes on a daily basis, it may not seem worth it to have a full-sized dishwasher. If that sounds like you, an 18-inch model may be a good option. Standard dishwashers measure 24 inches in width and can fit 10 to 16 place settings. These machines dominate the market and make up the bulk of the dishwashers that Consumer Reports tests, and most kitchens are designed to accommodate this dishwasher size. But a number of manufacturers also make dishwashers that are 18 inches wide. These slim designs typically fit eight to 10 place settings. With a little less room for dishes but a lot of the same offerings as standard dishwashers, they can be a great option for smaller households that are short on space in the kitchen.
Key Benefits of 18-Inch Dishwashers
- Space-saving design ideal for apartments, tiny homes, or small kitchens.
- Typically accommodates 8-10 place settings, suitable for small households.
- Energy-efficient, often Energy Star-certified, reducing water and energy costs.
- Available in built-in or portable models to suit different kitchen layouts.

Testing Scenarios and Performance
To evaluate the cleaning performance of the steady stream of new dishwashers we have coming and going in the Good Housekeeping Institute Home Care and Cleaning Lab, we meticulously soil multiple place settings of plates, bowls, cups and saucers, glassware and cookware with our standard greasy, starchy messes and make sure everything we’ve applied is dry and baked on (and yes, we skip the pre-rinse!). In our labs, we put each dishwasher through around 30 hours of tough trials to evaluate its performance on both counts. The best dishwashers can get dishes squeaky clean and almost completely dry while using minimal water and energy and running quietly enough that you forget they’re running at all.
Simulated Test Data
- Bosch SPX68B55UC: Cleaned 95% of baked-on food, dried 90% of dishes, including plastics, in a 2-hour cycle.
- Frigidaire FFBD1831US: Removed 90% of grease and stains, dried 85% of load, slightly wet plastics, in a 1.5-hour cycle.
- Samsung DW50T6060US: Achieved 93% cleaning efficiency, dried 88% of dishes, performed well with large pots.
Buying Guide for 18-Inch Dishwashers
Just because you have a small kitchen, doesn’t mean you can’t enjoy the convenience of a dishwasher. Here are key factors to consider when choosing the best 18-inch dishwasher for your home.
1. Size and Installation
Most 18 inch dishwashers measure 18 inches in width, 35 inches in height, and 24 inches deep. It is recommended to leave at least two inches of space between the wall or cabinet and the side of the open door. It is better to have at least 27 inches in front of the dishwasher for easy loading and unloading. Built-in dishwashers are designed to go underneath a countertop, and they are the most widely used dishwasher type in homes. If you don’t already have a space available in your kitchen where an 18” dishwasher would fit, then installing one becomes a much bigger and more costly job.
2. Capacity
The capacity of an 18-inch dishwasher is essential because these compact models offer a limited space. You can expect to be able to wash nine to ten place settings at a time, which should work well for small households. The number and types of racks differ from one dishwasher to another, and you should choose a model that works for the way you intend to use them. For example, if you want the dishwasher that can accommodate your stir fry wok or your large pots, you should opt for a model that has flexible racking.
3. Noise Level
Dishwashers can get pretty loud, so if you want an appliance that doesn’t drown your conversations, you should look for a model with a reputation for being quiet. Even though many brands advertise their dishwashers being particularly quiet, it’s important to have a look at customer reviews and see what other users have to say about the level of noise of the appliance. Models range from quiet (36 dB) to moderately quiet (55 dB), and you can also find appliances with overnight cycles, which means that you can set the dishes to wash without disturbing anyone’s sleep.
4. Energy Efficiency
According to the Environmental Protection Agency, Energy Star-certified dishwashers cost about $50 per year to operate and can save approximately 5,800 gallons of water over their lifetime. These machines use modern features like soil sensors, improved filtration, efficient jets, and optimized rack designs to reduce water and energy consumption. You’ll know a product is certified if it has a blue, square label. The EPA recommends choosing a dishwasher with multiple wash cycle options.
5. Features to Look For
- Adjustable Racks: For accommodating larger items like pots and pans.
- Sanitize Cycle: Eliminates 99% of bacteria for hygienic cleaning.
- Smart Connectivity: Allows remote monitoring and control via apps.
- Quiet Operation: Models under 48 dB are ideal for small spaces.
