5 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 EdgeStar BIDW1802WH is a built-in dishwasher designed for tight spaces with its slim 17.75-inch width, making it ideal for kitchens where space is limited or when replacing a trash compactor. It handles up to eight place settings, which is suitable for small households or couples. Energy-wise, it has an Energy Star rating, but its annual energy use of 234 kWh is on the moderate side compared to some more efficient models. The dishwasher operates quietly at 52 dB, so it won’t be disruptive in your home.

You’ll find six wash cycles including Heavy, Normal, ECO, Glass, Rapid, and Rinse, along with options like Sanitize and Heated Dry, giving good flexibility for different cleaning needs. Drying performance is enhanced by the heated dry option, which helps dishes come out ready to use. Inside, it features stainless steel racks and interior, which is a plus for durability and resisting odors. Installation is straightforward for a built-in model with standard dimensions, but be sure to measure your space carefully due to its compact footprint.

One thoughtful safety feature is the leakage sensor that stops water flow if a leak is detected, protecting your kitchen. The dishwasher uses push-button controls that might feel a bit basic, and with a depth of over 22 inches, it’s important to verify fit in smaller cabinets. While it is not the most energy-efficient option available, it offers a balance of capacity, quiet operation, and useful wash cycles, making it a solid choice for someone needing a space-saving dishwasher without many complex features.

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. Its noise level is rated at 52 decibels, which is moderately quiet but might still be noticeable in very quiet environments. The interior is stainless steel, which is durable and helps with better drying and resisting stains.

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.
