10 Dishwasher Dimensions (Buying Guide)

When you purchase a dishwasher, you'll need to consider the dimensions and the space you have. There are several options to choose from, including fully integrated, custom panel, compact, portable, and convertible dishwashers. You'll need to consider the style of your kitchen, your budget, and the amount of space available.

There are several considerations when purchasing a dishwasher. You’ll need to weigh the amount of space available, capacity, aesthetics, and expense to find the right dishwasher for your needs.

Built-in dishwashers come in compact and standard sizes. A compact dishwasher is 18″ and is suitable for smaller kitchens. It has a capacity of 6-8 place settings, which makes it an ideal choice for families of two or three people. A standard size is 24″, and hold up to 14 place setting. It’s a good choice if you have a standard size dishwasher opening or a family of three or more. Built-in dishwashers can also be semi-integrated or fully-integrated. These models sit flush with the cabinets for a more modern look.

Custom panel dishwashers accommodate a panel that matches your cabinets. You’ll need your cabinet maker to design the panel. You can then install it on the front of the dishwasher. They are specially designed to handle the extra weight of the panel. This is the most seamless look, but it’s also the most expensive.

Countertop dishwashers are the most budget-friendly. They are also the smallest. While they don’t take up as much overall space as other models, they do require space on your countertop, at least when they are in use.

Portable dishwashers are a great option if you are renting or plan to remodel. They are also ideal if you have a small kitchen or don’t have a dishwasher opening. Most portables have wheels so they can be wheeled out of the way when not in use, and the capacity is near that of compact or standard size dishwashers. Some portable dishwashers are also convertible, so they can be used as a built-in as well.

Built in 18″

The built-in 18″ dishwasher is a perfect choice for a small kitchen. The built-in design gives you maximum use out of your available space. It’s compact while still being functional. It’s the perfect choice for apartments or smaller dishwasher openings. This dishwasher requires an 18-19″ width, 34-35″ height, and 24″ depth. Choose the custom wood panel or the metal wood panel. Built-in dishwashers usually remain with the home, so they may not be the best option if you are renting a home or apartment.

Built-in 24″

This built-in 24″ dishwasher is the standard size. It should fit the dishwasher space in most newer homes, and it’s the most common size manufactured. It’s large enough to handle the needs of a family. As with any built-in, you’ll have to sacrifice some cabinet space for the convenience of a permanent dishwasher. The dishwasher is 23 3/4″ wide, 33 7/8″ high, and 22 1/2″ inches deep. You’ll need a clearance of 24-25″ wide, 33/ 7/8-35″ high, and 24 5/8-25 1/2″ depth. You’ll need a door clearance of 49 7/8″ total, or 27 3/8″ from the front of the dishwasher to open it fully.

Convertible Built In

This dishwasher gives you the best of both worlds. It’s a freestanding portable dishwasher that can also be used as a built in dishwasher with the installation kit. It’s a good choice if you want the space-saving feature of a built-in dishwasher. It’s best suited for those who need a portable dishwasher now, but want to convert to a built-in dishwasher at a later date. If you plan to move or remodel your kitchen, it’s the perfect choice.

The depth is 23 3/8″ to the door and 25 1/8″ including the door. The bottom depth is 21 1/2″ at the bottom. You’ll need to add 1/4″ for rear installation. The height is 34″ inches with a maximum of 35″. The width is 24″. You’ll also need 24 3/4″ door clearance.

Custom Panel Dishwasher

A custom panel dishwasher allows you to install a panel on the dishwasher that matches your cabinetry. This integrated look is often considered preferable to other options. If you want a modern look that allows your dishwasher to blend seamlessly with your cabinets, this is a good option. It is specially designed to accommodate the cabinet panel. They are typically more expensive than traditional built-ins, but the aesthetic is often considered to be worth the extra expense. You’ll need 34 1/8-36 1/2″ height clearance, 24-24 1/4″ width clearance, and 21 1/4-24″ inch depth clearance.

Dishwasher Parts

The interior of the dishwasher contains places to put your dishes and the components used to clean them. You’ll find the cup basket at the top of the interior of the dishwasher. Below that is the basket and the cutlery basket. These areas are designed to conveniently hold your dishes and place them in the correct area for optimal cleaning. Below that is the filter assembly and the spray arms. The spray arms spray the water that cleans your dishes. The door has the detergent and rinse aid dispensers. On the back of the dishwasher, you’ll find the inlet pipe connector, the drainpipe connector, and the power cord.

Fully Integrated Dishwasher

A fully integrated dishwasher is similar to a custom panel dishwasher. It will be completely flush with your kitchen cabinets, offering a more seamless look. The control panel is completely concealed, so you’ll only know it’s a dishwasher when it is open. It gives a modern and sleek look that works well in modern homes. The controls are placed on top of the dishwasher door. You’ll need 23 5/8″ width, 22 7/16″ depth, and  32 1/16-345-8″  height clearance.

Portable Countertop Dishwasher

A portable dishwasher sits on your countertop. You’ll need an outlet, and the dishwasher hooks up to your sink faucet. It will also drain into your sink. A countertop dishwasher is small, but it will take up space on your counter. It can be moved when it’s not used, but you will need a place to put it. You won’t be able to use water from your sink when the dishwasher is in use. It can save space because it’s easy to move out of the way when you aren’t using it. They have less capacity than built in dishwashers, but they work well for smaller families, those with limited space, and those on a tight budget.

The dishwasher dimensions are 20-24″ width, 22 3/8″ depth, and 25-28″ height. You’ll also need 45 1/2″ of clearance to open the door. The water supply, drain, and power cord are located on the back of the dishwasher near the bottom.

Portable Wheeled Dishwasher

A portable wheeled dishwasher can be placed in a dishwasher opening just like a built-in as long as you have the clearance for it. To do this, you’ll need a permanent water source as you would with a built-in. If you don’t have a dishwasher opening or don’t plan on staying in your home for a long period of time, you can keep it as a portable dishwasher. You’ll need to hook it to sink water supply, similar to a countertop dishwasher. However, the portable dishwasher can be rolled into a convenient area when it’s not in use.

Portable dishwashers are bigger than their countertop counterparts. They have many of the same features and capacity as a built-in. The dimensions are 23 7/8″ width, 20 3/4″ depth, and 33 7/8″ height. If you want to put it in a dishwasher opening, you’ll need 24-25″ width, 24″ depth, and 34-35″ height clearance.

Convertible Portable Dishwasher

A convertible portable dishwasher can be used as a freestanding dishwasher or a built-in with an installation kit. This offers the best of both worlds. If you need a portable dishwasher but plan on converting to a built-in at a later date, a convertible portable dishwasher is a good choice. They often include a top that can be used as a workspace in your kitchen. The dimensions are 36 1/8″ height including the top and wheels, 24 3/4″ width, and 27″ depth. The door requires 24 3/4″ inches of clearance space to open.

Semi-Integrated Dishwasher

The semi-integrated dishwasher sits flush with your cabinets to create a sleek look. The difference between a semi-integrated dishwasher and a fully integrated dishwasher is that the semi-integrated dishwasher has the control panel on the top front of the machine, so the control panels shows. It doesn’t look quite as seamless as a fully integrated model, but it is generally cheaper than fully integrated models, making them a popular choice for many homeowners. They are also considered easier to install and use. Many offer a digital display panel which may be worth giving up a completely integrated look.

The semi-integrated dishwasher has a height of 32 1/16″, a width of 23 9/16″, and depth of 22 7/16″. You’ll need 32 5/16-34″ height, 22 13/16″ depth, and 24″ width of clearance. You’ll also need 25 1/4 inch clearance space for the door to open.
