Small Dishwasher Dimensions: Will It Fit in Your Kitchen?

What is Considered a Small Dishwasher?

A small dishwasher is generally defined as any model narrower than the standard 24-inch width of a built-in unit. Most 18-inch dishwashers fall into this category, offering a space-saving solution without compromising cleaning efficiency. Ultra-compact options—like countertop dishwashers or in-sink models—take up even less space and are ideal for tiny kitchens, dorms, and RVs.

Standard Small Dishwasher Dimensions

Most small dishwashers fall into the 18-inch category, but dimensions may vary depending on the type and design. Here’s a quick breakdown of standard small dishwasher dimensions to help you plan your kitchen layout:

Types of Small Dishwashers

Not all compact dishwashers are built the same. Depending on your kitchen layout and lifestyle, different styles offer unique benefits:

Built-in Compact Dishwashers (18-inch wide)

Built-in compact dishwashers are the scaled-down version of standard built-ins, typically measuring about 18 inches wide. They’re installed under the countertop and connected directly to your plumbing, providing full-size performance in a smaller frame. Ideal for condos and galley kitchens, they can usually handle 6 to 8 place settings per load.

In-Sink Dishwashers

These dual-purpose units combine a sink, produce washer, and dishwasher into one efficient appliance. Installed directly into your countertop, FOTILE’s 2-in-1 and 3-in-1 in-sink models feature High-Pressure HydroJet Technology and convection drying, a perfect fit for small kitchens, RVs, and multi-use spaces.

Portable Dishwashers

These freestanding units can be wheeled into place when needed and stored away when not in use. They connect to a standard faucet, providing flexibility for renters or homes without dedicated dishwasher hookups. Though larger than countertop models, they save space and don’t require permanent installation.

Countertop Dishwashers

These compact units sit right on your kitchen counter and connect to the sink with a quick hookup. Countertop dishwashers are ideal for anyone working with limited kitchen space. Most can handle a few place settings per cycle, offering a convenient, water-saving alternative to handwashing.

Single and Double Drawer Dishwashers

Drawer dishwashers are installed into your cabinetry and open like a drawer. Single drawers are perfect for smaller households, while double-drawer models allow you to run two separate loads at once—ideal for multitasking or separating delicate items. With sleek design and easy access, these models are a popular choice for modern kitchens.

How to Measure Your Kitchen for a Small Dishwasher

Finding the right small dishwasher for your kitchen starts with taking proper measurements:

• Measure the width of the available cabinet or countertop opening. Most small dishwashers need at least 18 inches, but some models may need more surface area.
• Measure the depth from the front of your cabinets to the back wall. Standard depths range from 20 to 24 inches, depending on the model.
• Measure the height from the floor to the bottom of your countertop. Most small dishwashers require 32 to 34 inches of vertical space/
• Account for the clearance needed to open the door fully, especially in tight spaces or near corners.
• Consider surrounding fixtures like drawers, cabinet doors, and nearby appliances to make sure nothing will block operation or access.

Capacity: How Many Dishes Can Small Dishwashers Hold?

Don’t let their size fool you—small dishwashers can handle more dishes than you’d think:

• Built-in Compact Dishwashers (18-inch): Typically hold 6 to 8 place settings—enough for a family of two or three.
• In-Sink Dishwashers: Ideal for small households, these models can handle 2 to 4 place settings.
• Portable Dishwashers: Usually fit 8 to 10 place settings.
• Countertop Dishwashers: Designed for 2 to 6 place settings.

Ideal Kitchens For Small Dishwashers

Compact dishwashers offer high-powered cleaning with space-saving designs for compact kitchens:

• Apartments and condos
• Tiny homes and micro-apartments
• RVs and mobile homes
• Secondary or guest kitchenettes
• Studio apartments
• Older homes with limited plumbing access

Energy and Water Efficiency of Small Dishwashers

Small dishwashers consume less water and electricity per load than standard units—an eco-conscious choice for modern households. Many models, including FOTILE’s compact designs, carry ENERGY STAR® certifications and feature quick wash modes that reduce cycle time and resource use without sacrificing performance.
