Best Built in Microwave with Trim Kit

We'd steer most kitchens with an existing built-in cutout toward this one. It offers 2.2 cu. ft. of cooking space, sensors that set power level and cook time on their own, and trim kits in both 27 and 30 inch widths (sold separately), so a single microwave can serve either opening. The cutout it asks for is 24 3/4 inches wide, 20 inches deep and 16 3/4 inches high, so check the cabinet depth before anything else.

Owners report that it runs quieter than the older microwave it replaced, that the interior light is a cleaner white, and that it lines up well with the cabinet opening. Replacement installs bring one practical note: the support rails may need to be moved to match the new feet, and the door can rub the trim until the lower trim screws are set first. A common complaint is the locking system, since the door needs an unlock press after every use, and the controls draw mixed reactions because there is no automatic vegetable button. A reported failure is sparking inside the cavity shortly after the one-year warranty ended, which is worth weighing before you buy.

This is the one to look at when the cabinet opening is already cut and you want a single box to settle compatibility. The trim kit ships with the microwave, built for 24 inch wide openings, and the unit is rated for a cutout 15 3/4 inches high, 22 1/2 inches wide and 18 1/4 inches deep. That depth is shallower than the 20 inch cutout the Frigidaire Gallery Built-in Microwave 2.2 Cu Ft asks for, which matters in older kitchens with shallow cabinets. It runs at 1000 watts, with popcorn, pizza and beverage presets, weight or time defrost, multistage programming and a child lock, and its front-venting design lets it sit above or below the counter or over a wall oven.

Owners report quiet running, quick cooking, a clean built-in look from the stainless finish and trim, and straightforward installs. The limitations they name are a visible gap around the trim on the sides, a Start button that doubles as the 30-second add-on instead of having its own key, and a green clock display that some find off-color next to white-lit appliances. A reported failure is the unit losing all power during use.

It asks for the same cutout as the Frigidaire Gallery Built-in Microwave 2.2 Cu Ft, 24 3/4 inches wide, 20 inches deep and 16 3/4 inches high, with the unit itself a touch narrower at 24 3/8 inches. Where that model offers a choice of kits, this one names a single 30 inch built-in trim kit, sold separately, so it suits kitchens that already know their frame width. The 2.2 cu. ft. interior and sensor cooking are the draw.

Owners report a spacious interior and units that run without trouble. A common complaint is that the door needs an unlock press before it opens, that the lock function gets in the way, and that the popcorn button is close to useless. Reports of units that do not work at all and of quality-control lapses are the main reason we rank it as an alternative rather than a lead pick. Size draws both praise for the interior room and criticism that the unit is too big.

Aimed squarely at RV kitchens, this is the smallest oven in the lineup at 0.9 cu. ft., with a stainless steel finish and an included trim kit that gives a factory-installed look. Multiple power levels, preset cooking functions and an electronic touchpad with a digital display keep operation simple, and the built-in design frees counter space. Its body measures 15.5 × 21.5 × 12 inches and weighs 28 pounds.

Next to the Brama Built-In Microwave Oven 2.2 Cu.Ft., which offers far more interior, this one is sized for leftovers, frozen meals, snacks and warm drinks, so it is a poor match for large dishes. For a road kitchen where space is the constraint, that smaller interior is the point.

Against the Summit Appliance 24 Inch Built-in Microwave, which is rated at 1000 watts, this one runs at 1200 watts and offers a 2.2 cu. ft. interior, and it also ships with a trim kit meant for hassle-free built-in use. It can sit on a counter or be installed as a built-in, which gives flexibility if your plans change after you buy.

The control set is the broadest on the page: 10 adjustable power levels, express cook, a memory function, preset menus, defrost options, a silent mode, a timer and a touchscreen panel. Sensor technology reads moisture in the food to avoid overheating, a glass turntable rotates for even cooking, and a child lock is built in. Its footprint of 19.6 × 24.4 × 13.6 inches is close to the Frigidaire units, but confirm the cutout needed for this model before ordering. A one-year limited warranty is included.

This is a built-in, not an under-cabinet model, made as a direct replacement for Greystone and High Point units. It has 1.0 cu. ft. of space, a 10.5 inch turntable, 10 power levels, instant 30-second start and eight express cook options (popcorn, potato, pizza, beverage, soup, dinner plate, fresh vegetable and frozen vegetable), plus an included stainless picture frame trim kit. It is also offered in black.

Beside the Rugged Trail Products InVision RV Microwave, it adds a touch more capacity, 1.0 cu. ft. against 0.9, and it is aimed at a specific swap rather than general RV use. Owners report that it slid into an existing cabinet with little effort and that the trim lined up with the old screw holes. With a 900 watt output, a common observation is that it cooks a little slower than a home microwave. A reported limitation is that the outer frame can run narrower than advertised, so measure the opening before ordering.

This is the odd one out, a countertop model that can also be installed under a cabinet with an optional hanging kit sold separately. It offers 1.1 cu. ft., 800 watts, sensor cooking, one-touch express settings, 10 power levels and a child lock. The smart side is unusual here: Wi-Fi connectivity works with Alexa and Google Assistant, and scan-to-cook adjusts settings from a package barcode. It measures 12.88 × 24 × 11.87 inches and weighs 35 pounds.

At 800 watts it is lower-powered than the Brama Built-In Microwave Oven 2.2 Cu.Ft. at 1200 watts, so expect to add time to familiar recipes. Owners report very quiet operation, a good-looking finish and a clean fit as a replacement for an older Profile when paired with the matching trim kit; it also accommodates a 24 inch opening, even with the door open. The complaints are a door that sticks or needs a hard push to close, dimensions that were off and needed redrilled holes, and a keypad that is low in contrast and unlit, which makes it hard to read in dim light.
