Shop 18-Inch DishwashersWhat Is an 18” Dishwasher?
An 18-inch dishwasher is built specifically to fit 18 inches (≈45 cm) of cabinet width—ideal for narrow spaces that won’t accommodate standard 24” units. These models typically offer capacity for 8–10 place settings, which makes them excellent for singles, couples, or smaller kitchens where loads are lighter. They maintain standard depth and height (roughly 24″ deep × 35″ tall), so they integrate seamlessly with countertops and cabinetry. What they lose in width, they often make up for in smarter design—think third racks, fold-down tines, and advanced spray systems.
Importantly, despite their smaller size, many 18" dishwashers deliver high-end performance—matching full-size models in water and energy efficiency and offering features like sanitizing cycles, quiet operation, and stainless steel interiors. So if you were wondering whether an 18 in dishwasher could truly wash up to the task—the answer is a resounding yes, often with some clever engineering packed in.

18" Dishwasher FAQs
Absolutely! If space is tight, an 18" dishwasher offers full cleaning performance in a smaller footprint. You'll save water and energy while enjoying serious convenience. Smaller kitchens, apartments, and condos benefit most, and tech-heavy brands like Bosch and GE make no compromise on cleaning quality. Just plan for about 8-10 place setting loads.
Currently, LG does not offer an 18 inch dishwasher in their lineup. Their dishwashers are primarily standard 24” models. For 18-inch needs, consider brands like Bosch, GE, Samsung, Frigidaire, and Bertazzoni instead.
An 18 inch dishwasher typically holds 8–10 place settings for dinner plates, bowls, glasses, utensils, plus some pots and pans. Most units include a third rack for silverware and small items and adjustable racks for taller pieces. While you sacrifice a few plates compared to 24” models, clever rack design ensures you’re not sacrificing versatility.
Despite being smaller, 18 inch dishwashers often cost more due to their specialized engineering and lower production volumes. Compact units pack the same premium features—like stainless tubs, third racks, and smart sensors—into tighter frames, needing custom components. And with fewer models sold each year, economies of scale don’t offset costs.
