9 Best 18 Inch Dishwashers 2025 in the United States

The EdgeStar BIDW1802 is a compact 18-inch built-in dishwasher that effectively caters to small kitchens or space-constrained areas, accommodating up to eight place settings. Its sleek stainless steel design and Energy Star certification make it an appealing choice for eco-conscious users. Notably, it operates quietly at 52 decibels, which is a significant advantage for maintaining a peaceful home environment during use.

One of the standout features is its versatility, offering six wash cycles including Heavy, Normal, ECO, Glass, Rapid, and Rinse, along with options for sanitizing and heated drying, allowing for customized cleaning based on your specific needs. The inclusion of a leakage sensor is a wise safety feature, automatically cutting off water flow if a leak is detected, which helps prevent water damage.

There are some considerations to keep in mind. While the 8 place setting capacity is suitable for smaller households, it may not meet the needs of larger families or those who often entertain guests. Additionally, some users might find that the drying performance can vary, especially with plastic items, which may require additional drying time or manual drying afterward. The compact dimensions (17.75 inches wide) make it a great choice for replacing older appliances like trash compactors, but potential buyers should ensure their kitchen setup can accommodate these specific measurements.

It features a dual spray arm system that ensures thorough cleaning for every load. The inclusion of a National Sanitation Foundation Certified Sanitize Cycle adds an extra layer of cleanliness, making it great for those who prioritize hygiene.

The heated drying system effectively dries dishes, reducing the need for manual drying. The dishwasher's stainless steel interior is durable and resists stains and odors, while the compact design makes it an excellent space-saving option for tighter kitchens. Additionally, the energy efficiency of this appliance is commendable, as it is ENERGY STAR certified, which can help reduce electricity bills over time. The sound reduction system ensures that it operates quietly, which is a significant advantage for open-concept living spaces.

However, the limited capacity might be a drawback for larger families or for those who entertain frequently. The six wash cycle options, including Energy Saver and Heavy Wash, offer versatility, but some users might find the choices somewhat limited compared to other models that offer more specialized settings. The bundled garbage disposal unit, with its powerful grinding system, is a useful addition, helping manage food waste efficiently. It comes with BIOSHIELD antimicrobial odor protection, which prevents unpleasant smells. This bundle is a practical choice for those looking to maximize kitchen efficiency in a compact space, but it may not suffice for bigger households with more extensive dishwashing needs.

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.
