7 Best 18 Inch Dishwashers 2025 in the United States

The Honeywell 18 Inch Dishwasher is a compact and efficient option for those with limited kitchen space, offering a suitable capacity of 8 place settings. This makes it a great choice for smaller households or apartments. One of its notable strengths is the stainless steel tub, which enhances its durability and performance. The Energy Star rating indicates it operates efficiently, helping to keep energy costs down.

With 6 wash cycles including options for heavy, eco, and rapid cleaning, this dishwasher provides versatility to meet various cleaning needs, making it user-friendly for different types of loads. The 42 dB noise level is relatively quiet, allowing it to run without causing much disturbance in the home.

There are some drawbacks to consider. While the 8 place settings are adequate for small families, larger households might find it limiting. The built-in style means it needs to be installed under the counter, which may not suit every kitchen layout. Additionally, while the controls are straightforward, some users may prefer more advanced features or smart technology, which this model lacks. The 24-hour delay timer adds convenience for scheduling washes, though it may not be essential for everyone. This dishwasher is a solid choice for individuals or small families looking for an energy-efficient, space-saving unit that can handle everyday dishwashing tasks without much fuss.

The Frigidaire 18-inch ADA Compact Dishwasher is a solid choice for those needing a smaller built-in dishwasher without sacrificing key features.

The dishwasher is Energy Star certified, which means it uses electricity efficiently and helps reduce utility bills. Its noise level is 52 dB, quiet enough to operate comfortably even if you're in the same room. The dual spray arm system cleans dishes thoroughly, and the NSF certified sanitize cycle adds extra cleanliness for health-conscious users.

You get six wash cycle options including Energy Saver and Heavy Wash, providing flexibility for different dishwashing needs. The stainless steel interior is durable and helps with better drying, which is supported by the heated drying system to reduce leftover moisture. The compact dimensions (18"D x 22.5"W x 35"H) make it easy to fit into tight spaces, and it meets ADA standards, so it's designed to be accessible for users with disabilities.

The 8-place setting capacity might be limiting for larger households or frequent heavy use. While the noise is relatively low, it isn’t the quietest on the market when compared with premium models. Controls are basic front buttons with no advanced digital display, which can be simpler but less customizable. This dishwasher achieves a balance of efficiency, space-saving design, and performance, making it a practical option for compact kitchens or anyone needing an ADA-compliant appliance.

The KoolMore KM-DW1852-PR is a well-designed 18-inch dishwasher suited for smaller kitchens or households needing a compact yet efficient appliance. It offers a respectable capacity with 8 place settings and 4.3 cubic feet of interior space, which is quite good for its size. The dishwasher is Energy Star certified, meaning it uses power efficiently to help save on electricity bills.

It features six wash cycles including Auto, Normal, Heavy, Delicate, and Rinse, giving enough flexibility for various dishwashing needs, though it’s not as extensive as some higher-end models. The dishwasher has practical elements like slide-out racks with pop-up holders for better loading options and a removable utensil basket for convenience. Another highlight is its panel-ready front, allowing the dishwasher to blend seamlessly into your kitchen cabinetry for a clean look. Installation is versatile as it can be freestanding or built-in, fitting standard countertop heights.

On the downside, while 52 dB is decent, quieter dishwashers around 44-48 dB are available if silent operation is a priority. Also, the control type is push-button rather than a more modern touch interface, which might feel a bit basic to some. This dishwasher is a strong choice for anyone needing a compact, energy-efficient, and customizable dishwasher, especially where space is limited and a clean kitchen aesthetic is desired.
