What to Consider When Choosing the Best Built-In Microwave

Unlike countertop microwaves, built-in microwaves need to be the right fit for a kitchen. Among the many features to consider, the most important may be the installation space, cooking needs, microwave design, cooking settings, and size specifications when choosing the best built-in microwave for a kitchen.


There are a few different types of microwaves to consider: conventional, convection, and oven-microwave combos.

  • Conventional microwaves are the most common type of microwave. They work by heating up the water molecules in food via electromagnetic radiation. They are ideal for reheating, cooking, and thawing food, but these microwaves cannot brown or bake recipes.
  • Convection microwaves offer convection cooking that works similarly to baking or roasting in an oven. Beyond the typical microwave settings like simple reheating and cooking, these microwaves can roast, bake, brown, and crisp foods. Their convection feature has a heating element and a fan to circulate hot air. This operation works similarly to an oven to brown, crisp, and bake instead of only heating up the water molecules in food.
  • Oven-microwave combos combine a standard-size oven and microwave into one handy appliance, often with the microwave stacked on top of the oven. This allows for a uniform look and the full functionality of the two separate appliances.


A higher wattage typically means higher cooking power, as well as faster and more even heating. A microwave that has more than 800 watts is usually adequate heating power for most needs. Lower-wattage microwaves tend to be slower and may not heat evenly. If it has more than 1,000 watts, it is more powerful and has faster cooking times. However, higher wattage can come with a higher price tag, but these models usually have a higher wattage, too. Some run at around 1,200 watts for consistent and even cooking and heating.

Depending on their wattage and power consumption, some built-in microwaves require their own dedicated circuit. Sharing the same circuit as another major kitchen appliance can affect performance. Consult the user guide or a professional installer to check if this is the case with a chosen model.

Size and Capacity

A microwave size refers to the entire dimension of the unit, while the capacity describes the interior cooking space. Ensuring the right size is very important when choosing a built-in microwave. It needs to fit into the cabinet space with enough ventilation space for safe operation.

Many built-in microwaves come in 24-, 27-, or 30-inch widths to align with standard cabinet widths. Depth and height vary. Many range from 17 to 22 inches high and 20 to 25 inches deep. Microwave size can vary widely depending on the capacity.

Microwave capacities range from 0.5 cubic feet to 2 cubic feet, though some extra-large-capacity microwaves offer more than 2 cubic feet. The right size for a kitchen depends on the available space and intended use. For heating occasional leftovers, a smaller-capacity microwave might do the trick. For casseroles or larger dishes, home chefs may prefer a large-capacity model.

Before choosing a built-in microwave, be sure to measure the intended space and ventilation space. The required ventilation space will depend on the microwave model. Check the user guide for recommended cabinet dimensions to ensure the microwave will fit safely into the designated space.


Built-in microwaves serve many of the same functions as countertop microwaves: reheat, cook, bake, broil, roast, crisp, or thaw food. They can include a range of settings to make them easier to use.

While all microwaves will have manual timed cook settings, most also have a range of convenient shortcut buttons. These settings can prepare popcorn, potatoes, frozen dinners, and more at the touch of a button.

Smart microwaves can connect to Wi-Fi, allowing control from apps and smart-home voice devices. These microwaves can fit in nicely with an existing smart kitchen or smart-home system.


Built-in microwaves can include a variety of settings and control options. All built-in microwaves will have manual timed cook controls so the cooking time can be set. They also can have a range of preprogrammed settings and shortcut buttons, which will vary from model to model.

Common controls include automatic settings and preprogrammed buttons. Automatic defrost settings allow users to set food type and weight, and the microwave can automatically set the ideal settings. Preprogrammed shortcuts can include settings for cooking popcorn or heating pizza. These programs often use sensors to help heat or cook food. Sensor cooking settings assess the moisture level in food to adjust cooking power and time.

Smart microwaves enable users to control cooking settings and turn on the microwave through a smart device or voice commands, a convenient feature for those with smart-home systems.


Built-in microwaves should blend right in with the kitchen cabinets or walls. They can live in upper or lower cabinets, or in a drawer configuration.

The ideal pick may sit flush with kitchen surfaces so it doesn’t stick out. An unobtrusive built-in microwave frees up counter cooking space and doesn’t look clunky or add to cluttered kitchen surfaces.

For a cohesive look, consider a built-in microwave that matches the other appliances in the kitchen, whether stainless steel, black, or white. Most built-in microwaves come in neutral colors, like gray, black, and white. For a more high-end look, some models feature a drop-down door.

Additional Features

Some microwaves combine the functions of other kitchen appliances. For example, a convection microwave can roast and bake like a conventional oven. Microwave ovens may also include broiler and air-fryer features to crisp and fry foods.

Microwaves with additional features may include extra trays, like grill racks and air-fryer baskets. Tiered racks allow heating of multiple plates at once. In homes with children, buyers may want to consider a microwave with a child safety lock, which prevents accidental use by locking the control keypad. Users must enter a code to unlock the keypad.


Unlike countertop models, a built-in microwave requires installation. Depending on the model, some options require professional installation. Before buying a built-in microwave, it’s best to check the user guide to ensure you have a suitable outlet. Some models require the outlet to be in a certain location in relation to the microwave, like in the top right or left corner. In these cases, the ideal outlet area can be found in the microwave’s installation guide.

To ensure the microwave is safe, it needs to be properly bracketed into the wall or cupboard. When installing, it is important to ensure that the microwave has adequate ventilation space. Built-in microwave trim kits allow for a more seamless look, covering any gaps while also allowing ventilation. Once installed, the microwave location is permanent and will need to be uninstalled to be moved or repaired.

Some countertop microwaves can convert to built-in microwaves. Check the manufacturer’s directions on safe conversion for suitable placement and ventilation requirements. These options can be easier to install, and they usually just need a built-in microwave trim kit and an outlet.
