Single Drawer vs Double Drawer Dishwashers

Capacity: How Many Dishes Fit

The biggest difference between single and double drawer dishwashers is how many place settings they hold. ENERGY STAR classifies dishwashers as standard capacity if they hold more than eight place settings and six serving pieces, and compact if they hold less than that. A single drawer dishwasher is almost always a compact model, while a double drawer unit can hold more total dishes across its two drawers, but each drawer individually may still fall in the compact range.

If you need to wash a full dinner service for a family, a double drawer may give you the extra space, but you must check the manufacturer's place setting rating for each drawer. Remember that place settings are not the same as cubic feet; they refer to the number of standard dishes the manufacturer claims the dishwasher can hold. Learn more about how place settings are measured in our guide to dishwasher place settings.

Loading Flexibility: One Drawer or Two

A single drawer opens like a drawer, so you load everything at one level. That is easy to reach, but you only have one space to organize. A double drawer gives you two separate loading zones. You can run one drawer on a heavy cycle with pots and pans while the other drawer uses a delicate cycle for glasses. You can also load one drawer while the other is running, so you don't have to wait to start a load if the other drawer is full.

This flexibility is useful for small daily loads. If you only have a few dishes after breakfast, you can run just one drawer instead of filling a whole standard dishwasher. That can save water, but keep in mind that compact models may use more energy over time when compared with standard models, as ENERGY STAR notes. Running a single drawer frequently for small loads might be more efficient than running a large built-in with the same number of dishes.

For households that entertain often, a double drawer allows you to handle a large load by running both drawers together. However, you need to plan the loading carefully so that each drawer is packed properly. Refer to our loading guide for tips on arranging upper and lower racks, though drawer loading is somewhat different because there is no vertical stacking.

Kitchen Fit and Installation

Drawer dishwashers are designed to fit in a standard under-counter opening, typically 24 inches wide. A single drawer is a single box that slides in, while a double drawer is one unit with two slide-out racks. Both require a dedicated water supply, drain, and electrical connection. You should measure the height, width, and depth of your cabinet space before choosing, and leave room for the door to open fully. Our guides on standard dishwasher dimensions and how to measure for a dishwasher explain the steps.

Because the drawer pulls straight out, you may need less clearance in front of the unit compared with a traditional swinging door. This can be a benefit in a narrow kitchen aisle. However, you still need to make sure the drawer doesn't hit a cabinet or wall when fully extended. Also consider the height of the drawer front: some models allow you to attach a custom panel to match your cabinetry, which can affect the overall fit.

Energy and Water Efficiency

ENERGY STAR sets separate criteria for standard and compact dishwashers. Standard models must use no more than 240 kWh per year and 3.2 gallons per cycle, while compact models must use no more than 155 kWh per year and 2.0 gallons per cycle. A single drawer dishwasher is often compact, so it uses less water per cycle. Running a double drawer with only one drawer will still use that drawer's water, but a full double load across both drawers will add up.

ENERGY STAR also notes that due to their smaller capacity, compact models may use more energy than standard models over time. So if you constantly run two cycles to handle the same load a standard dishwasher would handle in one, a double drawer might not be the most efficient choice. Look for the ENERGY STAR label when comparing models, and check the yellow EnergyGuide label to estimate annual operating costs. For more on reading that label, see our EnergyGuide label article.

Drawer Dishwasher Benefits and Drawbacks

Drawer dishwashers offer ergonomic loading because the drawer slides out at a comfortable height, reducing the need to bend down to load a lower rack. This can be a major advantage for people with back problems or mobility issues. They also tend to have a shorter depth than some built-ins, which might help in tight kitchens.

On the downside, drawer models typically have a smaller total capacity than a full-size built-in dishwasher, even in double-drawer configurations. They may also be more expensive for the same place setting capacity. Before you choose, think about how many dishes you actually produce in a typical day. A double drawer might be overkill for a single person, while a single drawer might be insufficient for a family of four.

Which Should You Choose?

Choose a single drawer dishwasher if you live alone, have a small kitchen, or rarely need to wash more than a few place settings at once. It takes up less space and can be a good fit for a galley kitchen or apartment. For a larger household, or if you want to run two separate loads at the same time, a double drawer gives you more flexibility and total capacity.

What to pick for your use

Questions

Can a double drawer dishwasher run both drawers at the same time?

Yes, most double drawer models allow you to run each drawer independently or simultaneously, but check the manufacturer's instructions for your specific model. Each drawer has its own control panel and wash cycle.

How many place settings does a drawer dishwasher hold?

A single drawer is typically a compact model holding fewer than eight place settings. A double drawer holds more total, but each drawer may still be under eight. Check the spec sheet for the exact place setting rating.

Are drawer dishwashers as quiet as standard built-ins?

Noise levels vary by model. Look for the decibel rating to compare. You can see the range in our decibel level comparison. Drawer models often have two motors, so check the noise rating for each drawer.

Do drawer dishwashers clean as well as full-size dishwashers?

Drawer models use similar wash arms and filters, but the cleaning performance depends on the design and cycle options. Compare spray arm coverage and wash cycles before buying. Some drawer models have soil sensors and adjustable racks.

Can I install a single drawer dishwasher under a counter?

Yes, drawer dishwashers are designed for under-counter installation, but you must verify dimensions and clearance. Make sure the drawer can open fully without hitting the counter above or a handle on the adjacent cabinet.

What is the difference between a single drawer and a double drawer in terms of water use?

A single drawer uses less water per cycle because it has a smaller tub. A double drawer will use water based on which drawers you run. Running only one drawer uses about the same as a single drawer, but running both will use more.

Are drawer dishwashers good for small kitchens?

Yes, a single drawer is a good space-saving choice. Even a double drawer fits in a 24-inch opening but offers more capacity. Consider the total kitchen layout and how much counter space you have for loading.

Do drawer dishwashers require special installation?

Standard installation is similar to other built-ins: you need a water supply, drain line, and electrical outlet. Some models may require a different electrical connection, so check the specs. Our electrical connection guide provides details.
