To find the best built-in microwaves, you’ll need to consider the size, heating method, wattage, and control panels. You’ll want a microwave with dimensions that are compatible with your cabinets and allows for proper ventilation. Likewise, you’ll want to think about the interior capacity and the wattage as this can impact how quickly foods are cooked and whether you can fit more than dinner plates and small dishes inside of them. Serious cooks should prioritize convection or inverter-based models while casual users should be fine with intermittent or variable wattage models. And also consider whether you want a microwave with intuitive auto-cook presets and functionality or if you’re fine with a model that has minimal features.

After conducting thorough research through thousands of reviews, we nominated the Panasonic NN-SN686S built-in microwave as our Top Pick. Keep reading to learn more about our selection criteria and to review our recommendations for the best microwaves.

While you can use it as a countertop microwave, with the purchase of a trim kit, you can quickly create an upscale effect in your kitchen. The Panasonic microwave has external dimensions that measure 20.69 inches long, 15.81 inches deep, and 12.25 inches tall. It also has a 13.4-inch turntable which is good for most dinner plates.

Award: HONORABLE MENTION

WHY WE LIKE IT: The best built-in microwave with a trim kit that can be purchased separately with a compact 1.2 cubic feet of interior space and 1,200 watts of power that relies on inverter technology with 16 sensor cook settings.

  • 1200 watts for faster cooking
Cons
  • May not be ideal for larger families

Keeping with the idea of more compact built-in microwaves, we have the Panasonic NN-SN67KS. We think this is one of the best built-in microwaves with a trim kit that can be purchased separately — which is fairly standard for built-in microwaves from most brands. We like that this is another inverter technology based microwave that offers a powerful 1,200 watts for cooking and 1.2 cubic feet of interior capacity. This model measures 20.7 inches wide, 15.8 inches deep, and 12.2 inches tall with a turntable that has a 13.4-inch diameter.

 #3  Panasonic NN-SD372S Built In Microwave

Award: BEST QUALITY

WHY WE LIKE IT: The best microwave that relies on powerful inverter technology and intuitive features such as nine auto-cook presets and 950 watts of cooking power — all at an affordable price for budget shoppers.

Pros
  • Best on a budget
  • Comes with 9 auto cook options
  • Inverter powered for even temperature regulation
Cons
  • 0.8 cu. ft. interior may be too small for families

Typically, inverter and convection-powered microwaves are more expensive. But the Panasonic NN-SD372S is a great option for budget-focused shoppers. In addition to being our Best Quality, it’s also our Best on a Budget pick because we think it’s the best microwave where you get a variety of premium features along with inverter technology at an affordable price. The NN-SD372S is one of the smallest inverter microwaves that we’ve seen with an interior capacity of 0.8 cubic feet. We don’t think this would be a great pick for a large family, but it could work for a single person, or as a go-to solution in an office break room. The external dimensions measure 19.2 inches long, 14.81 inches deep, and 11 inches tall with a glass turntable that measures 11.25 inches in diameter.

Compared to other Panasonic models, this one comes in at just 950 watts. While this is still well above the recommended minimum of 700 watts, power microwave users may find this to be a deal-breaker. Still, this microwave comes with plenty of functionality. This countertop microwave can be reconfigured as a built-in if you opt to upgrade it by buying additional trim kits. Other important features with this pick include nine preset cooking options, Turbo Defrost, Keep Warm, and a Quick Minute for fast reheating. It’s a good option if you’re looking for the best microwaves for seniors.

If you’re all about aesthetics, then the Samsung MG14H3020CM microwave is going to be a smart choice. We like that the exterior features a sleek mirror finish that will look perfect as a built-in microwave. Keep in mind that you’ll need to buy the trim kit separately. We like the space-saving design of this countertop microwave that has 950 watts of cooking power and an internal capacity of 1.4 cubic feet. The external dimensions measure 21.9 inches wide, 18.1 inches deep, and 12.3 inches tall, which is perfect for most standard-width cabinets.

  • 1.2 cu. ft. and 1,000 watts
  • Sleek hidden control panel
Cons
  • May be a tight fit for cabinets 24” wide

When most people think about built-in microwaves, they think about installing the microwave in the upper cabinets. But some people like the idea of a more discreet placement, such as in the lower counters. We’re including the Sharp SMD2470AS because it’s one of the few under counter options we discovered in our research. This is why we think it’s the best built-in microwave for under the counter placement. As is standard, you’ll need to purchase the trim kit separately. We like that this model offers 1,000 watts, which puts it in the median range for power, and 1.2 cubic feet of interior capacity. The external dimensions measure 23.88 inches wide, 26.19 inches deep and 15.41 inches tall. So this may be a tight fit for standard cabinets that are 24 inches wide.

We also think this is a great pick because it features an easy touch automatic drawer that smoothly opens the interior. This mechanism also allows for hands-free closing. You’ll also get a discreetly hidden control panel that can be operated at a 45-degree angle. Note that this pick lacks a turntable but is rated as having enough interior space to support a four-quart casserole dish and is tall enough to hold a 20-ounce beverage cup. While this model does come with some presets, the options aren’t as robust as many of the other built-in microwaves that we reviewed in this guide.

It also features Genius Sensor technology and a large 15-inch turntable that can accommodate dinner plates as well as many cooking dishes. You also get common Panasonic features such as Turbo, Keep Warm, Sensor Reheat, and Quick 30. Choose from three finishes including stainless steel, black, and white.

Still, you’ll also get express start buttons for one to six minutes of quick cook time and a digital display control panel.

It’s a great built-in microwave convection oven that offers 1,100 watts of power and two cubic feet of interior capacity.

This microwave comes with a ceramic enamel interior that can easily be cleaned by simply wiping it with a damp cloth. You’ll get 1.9 cubic feet of interior capacity and 950 watts of power.

How We Decided

Built-in microwaves are a great solution for a kitchen appliance when you’re either trying to maximize counter space or want your microwave to seamlessly integrate into the rest of your kitchen decor. To create our guide, we focused on the following key features — size, heating method, wattage, and control panels.

Likewise, we include a range of wattage ratings but kept them between 950 and 1,250 watts. If you rely on a microwave as an oven replacement, then looking for models with ratings of 1,000 watts or higher is a smart choice. Whereas casual users will be fine with a 950-watt microwave.

Next, we considered the heating method. You’ll find that many of our recommendations are inverters. While inverter and convection microwave ovens tend to be more expensive than variable or intermittent pulse models, it is possible to find budget-friendly inverter models.

In terms of size, your biggest constraint is going to be the installation location. Since most cabinets are designed to be 24, 27, or 30 inches wide, you’ll need to keep that in mind as you shop for a built-in microwave. However, you can also use the internal capacity — which is listed in cubic feet — as a guide. You’ll note that in our guide, sizing ranged from as small as 0.8 cubic feet to as large as 2.2 feet.

And finally, we considered the control panel and overall functionality. All of our guides featured control panels with a digital timer display. But we did include models that relied on rotary dial and buttons as opposed to a touchpad. You’ll also want to think about whether or not you need auto-cook presets, or a wider array of power levels.

Best Built-in Microwave Buyer’s Guide

The Most Important Factors to Consider

  1. Size
    You can determine a microwave’s size by looking for the cubic footage. The interior capacity is always referenced with this figure, and based on the size, you can usually confirm that the exterior dimensions are going to be in proportion to the interior capacity. Microwaves range from as small as 0.6 cubic feet to as large as 2.2 or more cubic feet. You’ll need to think about where you plan on installing your built-in microwave and measure the dimensions of that space. You want to be sure that your microwave is compatible with those dimensions and that there’s enough clearance — especially in the back and sides — for hot air to be properly ventilated.
  2. Heating Method
    Convection and inverter microwaves are usually the most efficient methods since they result in more even cooking and less hot or cold spots. However, these models tend to be more expensive and are usually ideal for people who are using microwaves as oven replacements. But if you’re shopping on a budget, microwaves that rely on an intermittent pulse are usually more affordable, but less efficient.
  3. Wattage
    A microwave’s wattage is a sign of how powerful it is and how quickly it can cook foods. If you’re looking to use a microwave as an oven replacement, then you’ll want to look for a built-in microwave with a higher wattage. If you’re a casual user, then a model that’s at least 700 watts should be sufficient. Keep in mind that higher wattage microwaves are usually more expensive.
  4. Trim Kit
    To properly install a built-in microwave, you’re going to need a trim kit. Trim kits help to create a seamless appearance as if your microwave was always part of your cabinets or kitchen wall. They can come in a variety of finishes and often a brand will provide more than one trim kit for a microwave that can be configured as a built-in model. Usually, trim kits must be purchased separately.
  5. Control Panel
    The control panel will determine how easy or difficult it is to use your microwave. If you’re a power user, you’re going to want to focus on things like power levels, sensor cooking technology, or even additional features like grilling and auto-cook presets. If you’re looking for something easy to use, you can choose between the rotary dial, buttons, or touch controls.

Built-in Microwaves FAQs

Which is the best built-in microwave?

This is going to depend on your needs and the size constraints of wherever you plan on storing your microwave. But a good built-in microwave should come from a brand that offers a variety of trim kits so you can create a seamless look. Likewise, you’ll want to make sure that your microwave’s external dimensions are compatible with wherever you’re storing it and that the controls are robust and easy enough for you to use.

Are built in microwaves a standard size?

Most built-in microwaves are designed to fit cabinets that are a standard width. Since most standard cabinets are 24, 27, and 30 inches wide, you’ll want to look for a built-in with these width dimensions. Likewise, pay attention to the cabinet height as most built-in microwaves are also between 19 to 22 inches tall.

Does a built in microwave need ventilation?

Yes, they do. If you’re going to install a microwave into a wall or cabinet, then you need to make sure that there’s enough space around the microwave unit to allow for proper airflow. Failing to do so can encourage fire hazards.

How do I choose a built in microwave?

First, you need to measure the dimensions of the space where you plan to install your built-in microwave. Pay attention to the depth, width, and height as this will dictate how large your microwave can be. Keep in mind that you need to allow for enough clearance so that hot air coming out of the back or sides of your microwave can be properly ventilated. Consider the style of the microwave, as well as any features that you feel are essential. Then you’ll usually need to select a trim kit that is provided but the brand but must be purchased separately.
