12 Best 18-Inch Dishwashers: Less Space, Same Cleaning Luxury

An 18-inch dishwasher is a perfect choice for those who live in somewhat smaller apartments. They take up less floor space but still provide amazing features just like larger models do.

Keep reading my post to find out which of the 12 top-rated models is the perfect fit for you.

The Rundown

What Is An 18-Inch Dishwasher?

This is a compact dishwasher that is 18 inches wide, 24 inches deep, and 35 inches high. The 6 inches difference between that and the standard 24-inch big model, reduces the capacity to 8 or 10 place settings, while standard models can hold up to 16 place settings at the same time.

Is This Size Considered To Be Small?

Not really. It is smaller than a full-size model, but it is still big enough for standard-sized kitchens and the needs of a larger family and big household. The 3 main sizes of classic dishwashers are 18, 22, and 24 inches.

Narrow Design

What is great about 18-inch models is that they all feature a bit narrow design. This makes them an exceptional choice for smaller kitchens that simply don’t have enough floor space to fit larger models.

2 Model Options: Built-In & Freestanding

So built-in dishwashers are the first option and freestanding ones are the second option. Here are a few more details on each of the models.

• A built-in dishwasher with an 18-inch big unit is designed to fit the already existing cabinetry. It can have a control panel placed at the top of the door or at the front. Such a model doesn’t have finished back and top sides so they can be easier to build in.
• A freestanding dishwasher is, unlike a built-in one, finished on all sides so it can just be positioned next to the countertop or some other space that has available plumbing. Such a model can also come with wheels at its bottoms so it can be portable, easy to move, and store, as well as used only when it is needed.

Can I Get An 18-Inch Big Panel Ready Dishwasher?

Absolutely. This model allows you to install a custom panel on the face front of the dishwasher that matches the rest of your cabinetry.

Are These Dishwashers Available In Smaller Sizes?

Yes. Countertop models feature a unit that is between 14 and 18 inches big. Such a dishwasher is placed at the top of the countertop as it comes in such a small apartmant-size design. Also, there are manual models that are usually between 2 and 8 inches big.

Does This Model Use Less Water?

No. You buy this model to save space, not to save water. These dishwashers use the same amount of water and energy as full-sized dishwashers do. However, you can get a model that is Energy Start certificated. Here are the details.

• Such models use only 3 gallons of water per load. Stanard dishwashers that don’t have such a certificate use between 10 and 15 gallons of water per load.
• In the terms of energy, certificated dishwashers use only 0.87 kWh of energy per load. Standard models use 1.59 kWh.

How Much Do These 18-Inch Models Cost?

These dishwashers are usually priced between $600 and $1,200. This is a classic price range for standard 24-inch units too.

Best Brand Options

A couple of brands stand out with their production of 18-inch big dishwashers. Those are Bosch, GE, Miele, Frigidaire, Danby, EdgeStar, and SPT.

What Are Some Special Features Of A Dishwasher With 18-Inch Unit?

Before we get into all the classic functions and specifications this model comes with, here are a couple of benefits on which you can count on by buying this type of dishwasher.

Smart Soil Sensor Technology

This feature has the ability to automatically adjust the energy-consuming aspects of a wash cycle. Such a function is based on the soil load of the dishes. For example, if the dishwasher senses a relatively clean load, it can adjust the cycle that uses less energy and/or water.

Additional Smart Features

Besides the mentioned sensors, these models can also come with WiFi connectivity so you can control your dishwasher with a smartphone. They can have a time projector and interior LED lights. Such features can be quite convenient.

Third Rack

This feature is also quite convenient in a dishwasher. It provides you with additional space suitable for large utensils and silverware.

Here Are The 18-Inch Dishwasher’s Functions & Specifications

Now, let’s talk about the specs and functions that will ensure impeccable cleaning and drying performance.

Great Construction

Dishwashers with an 18-inch big unit usually have a stainless steel construction. This material of the making is the strongest and most durable material you can get. Besides, it emits minimal noise outside of the dishwasher, is resistant to corrosion, and ensures great drying results.

Can I Customize The Dishwasher’s Interior?

If the dishwasher comes with adjustable racks, then yes. This feature allows you to customize the interior by rearranging racks, baskets, and compartments so the dishwasher is suitable for awkwardly-shaped dishes and cookware too.

Multiple Cycles & Options

Most of these models come with about 4 standard cleaning cycles. The ones that are usually included are normal, light, heavy, and quick washes. Some other cycles you can also get are ECO mode, delicate, rinse only, glasses only, top-rack only, and many more, depending on the model you go for.

Powerful Drying Cycle: 2 Options

These 18-inch kitchen appliances can have 2 different types of drying. Here are the details on each of the options.

• Heated drying uses a heated element or a fan. It uses forced hot air to turn moisture on dishes into steam. Then, the air fans push the steam through exhaust vents. This is a really energy-consuming process so manufacturers are phasing it out more and more.
• Air drying use room temperature air to help dry your dishes. Unlike heated drying, this option is more efficient and easier on the dishwasher. It is considered to be an eco-friendly option too.

Can These Models Be Quiet?

Absolutely. These dishwashers can feature a noise level between 44 and 52 decibels. Bear in mind that the lower the decibel level, the quieter your machine will be. On the other hand, the quieter it is, the higher the price will be.
