What to Know Before Purchasing an 18-Inch Dishwasher

Just because you have a small kitchen doesn’t mean you should have to go without the convenience of a dishwasher. This is where the best 18-inch dishwasher comes in since it has a slim build and can fit into tiny spaces while being capable of washing many dishes.

If you are in a home by yourself or with another person, this kind of dishwasher works well since it won’t take as long to fill up so you can run it. This might lead to doing fewer dishes by hand if you worry about wasting energy and water.

On the other hand, large families with big kitchens may find a larger model is a better choice. But as someone with little space or a small household, the 18-inch dishwasher can be a game-changer. If you think an 18-inch dishwasher is the right choice for you, the information below might help you find the right one for your needs.

The Different Types of 18-Inch Dishwashers

As soon as you start searching for these smaller dishwashers, you’ll find that there are two main types that you can choose from, including built-in dishwashers and portable dishwashers. Both have pros and cons, which we’ll go over below.

Built-In Dishwashers

When you choose an integrated dishwasher, it is designed to fit under the counter to better integrate into your kitchen. These are going to look similar to full-size dishwashers other than being a bit smaller. You may also want to know that these dishwashers tend to be quieter than a portable model and can really add extra style into the space they are installed.

A built-in dishwasher is the best option for many if you have a built-in space already available and are replacing another 18-inch appliance. It can also work well in situations where you are remodeling a kitchen or building an entirely new one.

If the space isn’t available already, the installation of a built-in can take more time and effort. That doesn’t mean you shouldn’t choose this option, but you want to think about the extra challenges it will bring. Many people are still interested in this dishwasher type since it fits into the space rather than being separate and in the way.

Portable Dishwashers

With a portable dishwasher, the machine cannot be built into or stored under your counters, which means you need another space to place it. Even though an 18-inch dishwasher is smaller than a traditional model, it can still take up a good amount of space. Purchasing one that is in the way and a hassle to use is just going to make you frustrated with the option you chose.

You need to be sure there is plenty of floor space for a portable dishwasher. For those with tiny kitchens, this may mean you need to store it elsewhere and bring it out only when needed. You will want to think about whether you are open to putting all that effort in every time you do your dishes.

Another benefit of a portable machine is that if you are renting and don’t want to leave it behind when you move, you can take it wherever you go next. If your rental space doesn’t have a dishwasher, this can be an excellent option to avoid regularly hand washing your plates and cups.

Essential Factors to Consider When Buying an 18-Inch Dishwasher

There are many different considerations you should keep in mind when you are comparing 18-inch dishwashers for purchase. When choosing a dishwasher, as with any electronic appliance, there is the potential for malfunctions if it isn’t made well or maintained over its life. Since you likely want one that lasts for many years, going with the right brand and getting the best features is a must.

Whether you simply want to upgrade your old dishwasher, need to replace a broken appliance, or are remodeling your kitchen, the factors below should go into your final decision of which to buy.


While the size of the dishwasher is essential, the actual capacity or amount of dishes that the device can hold is also significant. You are going to want to think about both how many dishes will fit into the machine as well as what types of dishes will fit. Those who rarely cook may only need a dishwasher that fits a few plates, glasses, and silverware, while those who often cook might want something that will accommodate large pots and pans.

Every person is going to be different in terms of the right dishwasher capacity. Consider what dishes you use the most often and then take a look at rack layouts for the dishwasher you might choose to buy. If it doesn’t fit all the dishes you need, you’ll end up doing hand washing, which can take up extra time and energy.

Adjustability and Rack Size

This is related to capacity but well worth its own category. The racks in your dishwasher will determine how you can use it and which dishes will fit into it. Adjustable shelves and tines that bend down offer additional flexibility based on your needs. If the racks aren’t suited for the dishes you use, it can cause frustration and require you to do more washing by hand.

Are you planning to purchase your dishwasher online? If so, take a look at pictures of the rack set up for various models and look at reviews in terms of how hard it is to fit individual dishes. With an 18-inch dishwasher, it’s going to be smaller than average, so you should have racks that let you get the most out of the space available. Some manufacturers will do better with this than others.


While the 18-inch dishwasher is going to take up less space than a full-size machine, it is still going to be large enough that you want it to look beautiful in your kitchen. This is especially true if you are choosing a built-in dishwasher, which is going to be permanent for several years. While there are limited aesthetics available with smaller dishwashers, there are several colors, finishes, and styles that you can choose from based on the look of your kitchen.


Cost is always going to be critical with a significant purchase like a dishwasher, but thankfully, 18-inch dishwashers tend to be less expensive than traditional ones. That means you’ll save money by default, but there also can be various costs based on what you need the machine to do for you.

One factor that really breaks down prices is whether you are choosing a portable dishwasher or one that is built-in. If you choose the premium top of the line portable dishwasher, it could cost more than a built-in with fewer features. However, in most cases, built-in dishwashers are going to cost more than portable machines are.

Prices can vary with either type of dishwasher, so you’ll want to explore your budget and what options are in that category. Whether you use a built-in or a portable machine, those from top manufacturers are often more expensive. However, these are also the dishwashers that tend to use quality products and might offer extra features like additional wash settings and adjustable racks.

Cycle Settings

You might think that the number of wash settings available isn’t significant, but it gives you more control each time you use the machine. For instance, those who want to save water will want a setting for that. If you want different settings for delicate dishes compared to tough to clean dishes, that’s another thing to take into consideration.

Most of the best dishwashers will have settings similar to full-size machines, so don’t feel like you need to give up things you want to get the size you prefer. The best thing you can do is browse your options and come up with an idea of what your needs and preferences are for your new dishwasher. Then you can choose a machine that has the settings you are most likely to use regularly.

Energy Efficiency

Are you going from an older dishwasher to a more modern one? If you are, you’re going to find new machines use less energy than older ones do. In addition to that, 18-inch dishwashers are going to use less energy than a full-sized machine is going to.

However, keep in mind that some models are going to be more efficient than others. To be sure you choose an energy-efficient dishwasher, consider purchasing an Energy Star machine. These dishwashers are about 12% more efficient and will use approximately 1/3 the water of dishwashers that do not have an Energy Star rating.


The basic premise behind choosing the 18-inch dishwasher is that it will get your dishes shiny and clean every time without you having to scrub or soak the pots and pans. If pre-cleaning is required before using the dishwasher, there’s no real reason to have a dishwasher. Make sure to look at the dishwasher specifications and read reviews to get an idea of how well the machine functions.

Functionality is going to be one of the most important factors to think about when choosing a new dishwasher. This also includes the number of settings the dishwasher has since that can create better functionality in various situations. Selecting the perfect settings will ensure your dishes come out clean and ready to go every time you use the dishwasher.

Noise Level

Have you ever had a dishwasher that is so loud that it sounds like a plane flying overhead? Most of us have, and it’s not something most of us want to deal with. If you hate noisy appliances, you don’t want a dishwasher that is so loud you can’t hear the television or engage in a conversation with friends or family members.

If a quiet dishwasher that is only mild background sound is a priority to you, make sure that’s something your chosen dishwasher provides. You’ll notice some brands mention how quiet their machines are, but you can also peruse reviews to see what past buyers have to say about the level of noise you can expect.


Are you already set on a dishwasher that is 18-inches? If so, size isn’t something you need to think about much at this point. However, you also want to make sure the other dimensions of the dishwasher will work with the space where you plan to install it.

Measure out the space you have before you choose the dishwasher that you want to buy. You should measure height, depth, and length to determine whether it is going to fit. You also want to be sure it won’t take up so much space that you can move around the kitchen the way you would like.


Everyone is in a different space and has specific needs when choosing the best 18-inch dishwasher, which means a bit of research can go a long way. With several options on the market, knowing which features to watch for can ensure you select a machine that works well with your lifestyle. For some, that might be a built-in dishwasher, while others might prefer a portable dishwasher.

While an 18-inch dishwasher can do all the things a full-size model can do, it also takes up less space and will fit a smaller amount of dishes. Don’t feel as if you can’t enjoy the convenience of a dishwasher just because you are in a smaller space. Take a look at the dishwashers above to find the one that meets your needs and fits your budget.
