6 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.

The Frigidaire FFBD1831US 18-inch dishwasher and garbage disposal bundle offers a compact and efficient solution for smaller kitchens. With a capacity to clean up to 8 place settings in one cycle, this dishwasher is ideal for small households or apartment living. 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.

It also includes a heated drying system, which can effectively dry dishes after a wash cycle. Additionally, users have six cleaning cycle options including Energy Saver and Heavy Wash, providing versatility for different cleaning needs. The dishwasher is Energy Star certified, offering energy efficiency and cost savings over time.

Moreover, the NSF Certified Sanitize Cycle is a noteworthy feature for hygiene-conscious users, removing 99.9% of common household germs. The ADA compliance makes it accessible for users with disabilities, which could be an important consideration for some buyers. However, the interior material is plastic, which might not be as durable as stainless steel alternatives.
