How to Find the Ideal Dishwasher Opening

Share your love

The standard dishwasher opening is 24″ wide and 18.5″ high. This standard size has been used for many years, but as people’s kitchen remodeling needs change, the formal dishwasher opening may not be compatible with your layout. Luckily, you can do a few things to make sure you find the right fit for your kitchen!

Standard Sizes

There are three different kinds: space-saver, regular, and enormous. Some minor variations in width, height, or depth may exist among these models. The dishwasher’s rough opening, on the other hand, can accommodate some minor changes; therefore, if you’re replacing an old dishwasher with a new one, it will most likely fit the area.

Measuring Your Opening

The standard size for most dishwashers is the same as the opening created in most cabinetry. However, there may be variations, such as a cabinet built around a particular model with unusual dimensions. To determine your opening’s width, depth, and height, measure from the inside edge of the hole to the inside edge of the door.

Remove any trim or decorative overlays that may have been included; these are sometimes used to fill up the extra space if the aperture is too big or the dishwasher is too small, and they can be removed as needed.

Standard Dishwashers

With adjustable feet, most undercounter dishwashers are approximately 24 inches wide, 24 inches deep, and 35 inches tall. This implies that your cabinets’ rough opening must be a minimum of 24 by 24 by 35 inches.

The dishwasher’s dimensions are around 23.5 inches wide, 23.5 inches deep, and 34 inches high. Some wiggle room is required to place and connect the dishwasher; a slightly loose fit is preferable to a tight one. If your rough opening is shorter than this measurement, consider getting a space-saver dishwasher with decorative trim to conceal the sides.

Space-Saver Dishwashers

Space-saver dishwashers are designed to work in small kitchens, apartment kitchens and renovate existing kitchen space with a dishwasher for the first time. They have the same depth and height criteria as a regular-sized dishwasher (24 inches deep by 35 inches tall), but they are usually about 18 (or 17 5/8) inches wide.

They can fit into any hole at least 18 inches wide, so they may be stowed anywhere a 20-inch or 22-inch dishwasher used to be. They can also frequently be accommodated in a series of cabinets after they have been put in place.

Oversized Dishwashers

Oversized dishwashers are a relatively new invention. They’re used in big kitchens, modern kitchens, and large family kitchens. They need the same 24-inch depth and 35-inch height opening as a regular dishwasher, but they take up considerably more space.

The most frequent dishwasher size is 30 inches, although they are available in sizes up to 42 inches. However, an oversized dishwasher must be chosen at the time of cabinet installation to accommodate the extra breadth in the design.
