A built-in microwave only works if it physically fits the hole you have — or the hole you are willing to cut. That is the whole game here. The wrong pick means a trim kit that does not line up, a drawer that fouls the cabinet door, or a unit that has to come back out. The right pick keeps your counter clear and puts reheating at waist height.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Some of these ship with the trim; others leave you to buy it separately, which changes the real cost of the install. Below you get the cutout numbers, the power levels, and the honest install caveats for every pick. Here is how to choose a cabinet microwave that actually drops into your opening without a return label.
Our Picks at a Glance
How To Choose The Best Cabinet Microwave
Two things decide whether you are happy with a cabinet microwave: whether it fits your opening, and whether the door or drawer is something you can live with for a decade. Everything else — wattage, presets, sensor cooking — is second-order once the box is in the wall.
Measure the cutout, not the appliance
The number that governs whether this installs is the cutout — the rough opening in your cabinetry, not the outer size of the unit. A 2.2 cu. ft. built-in like the Frigidaire wants a 24 3/4 inch wide, 20 inch deep, 16 3/4 inch tall cutout. A drawer unit like the Midea lists its own body at 23.5 inches deep by 23.6 wide by 15 high, so the cavity it needs is a different shape entirely. Take a tape measure to your opening before you read anything else.
Drawer versus fixed built-in
A drawer pulls out toward you like a cabinet drawer and sits under the counter — you load food from above, which is easier on your back and shoulders. A fixed built-in mounts in the wall or over a wall oven and opens with a swing door; you get a bigger interior volume, often 2.2 cu. ft. versus 1.2 on most drawers. If you regularly cook for a family and want a large casserole dish inside, the fixed unit wins. If you want your countertop back and hate reaching over a hot door, the drawer wins.
Trim kit: included or extra
The trim kit is the stainless frame that covers the gap between the appliance and your cabinet. Some units ship with it in the box, like the Summit, which includes the bottom ducts, rails, and frame. Others, like the Frigidaire, sell the trim kit separately as an optional part. Check that line before you budget the install, because the frame is not optional if you want a clean look.

In‑Depth Reviews
1. Frigidaire Gallery Series GMBS3068BF 2.2 cu. ft. Built-in Microwave Oven
Our pick — 4.5+★ from 250+ verified ratings; the strongest balance of quality and price.
The biggest interior on this list, and the one whole families tend to settle on.
The number that sells this one is 2.2 cubic feet — a cavern compared with the 1.2 cubic feet almost every drawer unit here offers. That gap in usable space is the difference between fitting a large casserole dish with room to spare and playing Tetris with dinner plates. The sensor system detects the food and sets power and time on its own, so leftovers and reheat jobs do not need you standing there guessing.
The crowd favorite at 4.5+ stars across 280+ owners, and the consensus on what wins people over is plain build quality — it feels like a proper appliance, not a countertop box bolted into a hole. Fit is the second big talking point, and the measurements back that up: a 24 3/4 inch wide, 20 inch deep, 16 3/4 inch tall cutout, with an outer width of 24 7/16 inches and a depth of 19 5/8 inches. It also runs quietly enough that owners keep bringing it up unprompted. The one install catch is that the trim kit sells separately in 27-inch (GMTK2768AF) and 30-inch (GMTK3068AF) versions — budget for the frame and confirm the size before you cut.
What earns it the top slot
- 2.2 cu. ft. — the largest capacity here, with room for big dishes and multiple items
- Sensor cooking and sensor reheat set power and time automatically
- Quiet running that owners call out on their own
- Auto defrost, quick start, and a child safety lock built in
What to plan around
- Trim kit is sold separately — order the right width before install day
- The control layout draws mixed reactions, including the missing veggie auto button
- The locking mechanism is the most-cited frustration
Reach for this if: you cook for a household and want the most interior room plus automatic sensor cooking.
Double-check first: price the matching 27-inch or 30-inch trim kit into the job and confirm your cutout measures up.
2. Summit 27” Built-in Microwave with Trim Kit, Stainless Steel – SMBI27TK27
Ships with the stainless frame in the box, so there is no second order before install.
Most built-ins here make you buy the trim kit as an extra part. The Summit includes the bottom ducts, rails, and frame for a flush fit in a 27-inch wide cabinet opening, or directly over a wall oven. That one detail saves you a separate purchase and a second sizing decision. The brushed stainless trim has a horizontal grain to match your other kitchen fixtures, and the large viewing window plus end-of-cycle buzzer make it feel finished rather than purely functional.
Inside you get 2.2 cubic feet and a big removable glass turntable, driven by 1200 watts — the highest power figure on this list. That extra wattage matters most on dense food where you want even heating rather than cold spots in the middle. Functionality is what owners single out first, followed by quality and looks, and the fit feedback includes a buyer reporting it accommodates odd-shaped cutouts. It weighs 75 pounds, so plan for two people at install.
A 27-inch-wide frame means a 27-inch-wide opening — this one is not going to squeeze into a 24-inch slot. The recommended cutout is 17.13 inches high by 25.5 wide by 22.75 deep, and the outer dimensions with the trim kit are 18.88 inches high, 26.88 wide, 19.63 deep. Measure your opening against the cutout figure, not the outer frame, before you commit.
Where it pulls ahead: 26.88 inches of outer width and 18.88 inches of height make this a 27-inch cabinet solution, and at 1200 watts it sits above the 1000W drawer units that dominate this list.
The honest trade: a narrow 27-inch opening is required, and the finished unit is a 75-pound lift, so factor in a helper and a solid mounting surface.
Best for: a 27-inch cabinet opening where you want the trim, frame, and ducts all in the same box.
Think twice if: your cavity is a standard 24-inch drawer slot — this will not fit it, no matter the trim.
3. KoolMore 24 Inch Stainless-Steel Microwave Drawer with 1.2 cu. ft. Capacity
The drawer that slides out on one touch and closes softly, so nothing slams.
Where the Frigidaire offers 2.2 cubic feet, this KoolMore delivers 1.2 cubic feet — a much smaller cavity, but arranged as a flat-bottom drawer you pull toward you rather than a box you reach into. Mount it into the wall or your cabinetry and you free up counter space without hanging a unit over the stove. The one-touch open door and slow-close mechanism make loading food simple, and the flat-bottom design trims wasted space inside the cabinet run.
What owners keep coming back to is quality, followed closely by appearance — the stainless finish blends in whether your kitchen runs modern or farmhouse. Installation is straight and the interface is easy to learn. Power is 1000 watts with 10 custom cooking levels plus memory and timer functions, running on standard 120V/60Hz household power. For anything delicate — melting butter, softening cream cheese — those finer power steps are what keep you from scorching instead of warming.
The 1.2 cubic feet is honest: this accommodates everyday plates and containers rather than a giant casserole the way a 2.2 cu. ft. built-in would. If you routinely reheat big casserole dishes for a family, the 2.2 cu. ft. built-in is the better fit. Otherwise, the stainless front sits flush and reads as built-in cabinetry.
Built for looks: 10 power levels with memory and timer control, plus a premium pull handle and slow-close door.
Where it gives ground: 1.2 cubic feet versus 2.2 on the big built-ins — this is daily-reheat capacity, not cook-a-feast capacity.
Pick this: if you want counter space back and a drawer that opens automatically with a single touch.
Skip it: if your regular cooking involves oversized casserole dishes that need a deep interior.
4. GASLAND 24 Inch Built-In Microwave Drawer, 1.2 Cu.Ft, 1000W
Silent mode and anti-pinch hardware for kitchens where everyone can hear the beeps.
If your microwave sits on an island in an open-plan room, every beep carries. This one adds a Silent Mode that cuts the button-press and end-of-cook chimes, which is a feature you rarely see spelled out on a microwave drawer. The anti-pinch protection and child lock go further than most, since a drawer that slides closed toward little fingers is a real hazard in a busy household.
You get 1000 watts across 11 adjustable power levels, plus four auto-menus for Melt, Popcorn, Soften, and Beverage. The 1.2 cubic feet accepts a 12-inch pizza, large dinner plates, and casserole dishes, and the unit is UL Listed. Installation is under-counter built-in, so your countertop stays clear. It measures 22.9 inches deep, 23.9 wide, and 15 high.
Here is the honest part: durability is the most-discussed subject across the review pages, and the reports are mixed — some units are fine, but buyers report the door falling apart and the handle breaking after a month of use. Noise feedback splits too, some finding it quiet and others saying it is noisy. This is still a capable drawer, but the anti-pinch safety hardware is worth inspecting and gentle handling of the handle is prudent in the early months.
Worth it for: anyone who wants a drawer that stays quiet in an open kitchen and adds child-safety hardware.
Know going in: durability feedback is the mixed spot on this model, so treat the handle and door track with care and keep the receipt.
5. 30 in. Haven Coll 1.2 cu. ft. Built-in Microwave Drawer, Stainless Steel
A 30-inch wide drawer for wider cabinet runs that the 24-inch models leave short.
Wide cabinet bank? The 29.9-inch width here is the number that matters, because most of the drawers on this list stop at 23.9 inches. If you are replacing a unit in a 30-inch opening, the width is what decides your shortlist before anything else. The 1000 watts with 10 power levels give you fine control, and four presets — melt, soften, popcorn, and beverage — cover the everyday jobs.
Performance is what earns this one its followers, and the feedback on it is that it exceeds expectations. Easy install comes up repeatedly, described as plug-in play, and the exterior measurements are 29.9 inches wide by 23.2 deep by 16 high on standard 120V/60Hz power. Included is a defrosting rack, which lifts food off the floor of the drawer so liquid does not pool around it — a small thing that makes defrosting more even. A one-year limited warranty with support based in the USA rounds it out.
This is a drawer, not a wall oven replacement, so 1.2 cu. ft. still sets the limit on dish size. It holds everyday plates and containers comfortably. The trade is that a 30-inch footprint is not a common retrofit size, so measure your actual opening carefully — a 24-inch slot leaves you needing a different unit entirely.
Reasons buyers lean to it
- 29.9-inch width fits a 30-inch cabinet run
- 10 power levels with four automatic presets
- Weight or timed defrost plus a defrosting rack included
Where it is limited
- 1.2 cubic feet means oversized dishes will not fit
- 30-inch opening required, which is a less common retrofit size
The right call if: your cabinet opening is 30 inches wide and you want a drawer that fills it.
Not for: a 24-inch cavity — the width will not cooperate no matter how good the specs are.
6. Midea Microwave Drawer Oven, 1.2 Cu.Ft, 1000W, Stainless Steel
Built around the chore nobody likes: scrubbing the inside of a microwave.
The 1.2 cubic feet is roomy enough for a range of dish sizes, and the body measures 23.5 inches deep by 23.6 wide by 15 high — a tight fit for a standard 24-inch drawer slot. A one-touch start means a gentle press gets you cooking, no dial-turning.
Power sits at 1000 watts with 11 power levels, letting you go from delicate defrost to full reheat without a jump in intensity. Auto-menus adjust the settings for you, and defrosting works by either weight or time, so you pick the method that matches the frozen item. A child lock keeps kids out of a drawer at floor level, which is exactly where curious hands go.
The limitation to plan for is that a sub-two-foot capacity cannot swallow a huge casserole or a giant holiday bird — this is a daily-use drawer. For everyday plates, containers, and reheating, 1.2 cubic feet is enough. The Midea is a solid value pick if easy cleaning and floor-level child safety matter to your routine.
Standout spec: 11 power levels plus weight or time defrost gives you fine control over delicate jobs.
The practical catch: 1.2 cubic feet is a daily-reheat interior, so oversized dishes are where you should set expectations.
Good match for: a busy kitchen where easy cleaning and a floor-level child lock matter most.
Look elsewhere if: you need to reheat very large dishes on the regular.
7. Sharp KB6524PSY 24 in. 1.2 cu. ft. Built-In Microwave Drawer Oven
A long-running drawer design that still fits a 4 qt. casserole dish.
This one has been the reference point in the drawer category for years, and the spec that keeps it in demand is the 4 qt. casserole fit — that is a genuine lasagna or big-batch dish, not a plate of leftovers. It runs 950 watts, the lowest figure among the drawers here, which is a modest step down from the 1000W units. Auto-touch controls and auto defrost are straightforward, and the low-profile design sits flush under the counter.
The drawer design and easy installation are what people praise most, and the low-profile stainless finish drops into a modern or transitional kitchen cleanly. Where this one asks for patience is longevity. Reliability and value are the two most-discussed subjects on its review pages, and the reports are genuinely mixed — plenty of units work great for years, but some stop working in a short stretch and others are called overpriced for how long they last. There are also reports of units catching fire, which is a serious note that belongs in any honest picture of a unit at this price.
The 1.2 cubic feet and 950 watts mean this is a proven, well-understood drawer, not a powerhouse. If you want the least risk on a long-term install, check the warranty terms and buy from a seller with an easy return policy. If a 4 qt. casserole capacity in a pull-out drawer is your priority, this delivers it.
The case in its favor
- Fits a 4 qt. casserole dish — a real family-sized capacity in a drawer
- Auto-touch controls plus auto defrost
- Low-profile stainless design that installs easily
The things to weigh
- 950 watts — the lowest power in this drawer group
- Reliability is the most-discussed topic and the feedback is mixed
- Some reports of unit fires — verify warranty and return terms
Choose it for: the casserole-size capacity and the familiar, well-documented drawer layout.
Check before buying: the warranty and seller return policy, given the mixed long-term reliability feedback.
8. Café 1.2 Cu Ft 24″ Microwave Drawer, 1000W, Sensor Cooking, Matte White
The matte white drawer for kitchens where the appliances are part of the design.
Matte white is the reason to look at this one. In a kitchen built around white or light cabinetry, the finish disappears into the design rather than breaking it, and the glass touch controls keep the front clean and wipeable. The drawer extends like a cabinet drawer under the counter and opens with an electronic button — no handle to grab. Dimensions are 23.31 inches deep by 23.88 wide by 15.94 high.
Sensor cooking and sensor reheat are the practical core here, adjusting time and power automatically for packaged foods and leftovers so you are not dialing in minutes each time. You get 10 power levels, useful for nudging from a gentle defrost up to a full reheat, and Express Cook adds one-button cooking from 1 to 6 minutes. The 1000 watts of cooking power handles the everyday jobs. The listed electrical figure is 1500 watts, which is the draw you should match to your circuit.
At 1.2 cubic feet this is a daily-reheat drawer, not a large-dish oven, so plan accordingly. The matte white finish also shows smudges a little more than stainless, so it rewards a quick wipe. If your kitchen palette is white or light, the matte white front blends into the cabinetry.
Design-first pick: matte white finish, glass touch controls, and an electronic handleless open.
The trade-off: 1.2 cubic feet limits dish size, and a 1500-watt electrical draw needs a circuit that matches.
Perfect for: a white or light kitchen where the finish is as important as the function.
Reconsider if: you want stainless to match, or you regularly cook large dishes.
Understanding the Specs
Capacity in cubic feet
This figure is the volume of the cooking cavity — the usable space, not the size of the box. A 2.2 cu. ft. built-in gives you a big interior that swallows casserole dishes and multiple plates at once. A 1.2 cu. ft. drawer is the standard size for a pull-out and covers everyday plates and containers. Match capacity to how you actually cook: big-batch family meals lean toward the larger fixed built-ins.
Wattage
Watts are the cooking power, and higher means denser food heats more evenly inside. The units here range from 950W on the Sharp to 1200W on the Summit, with the drawer units sitting at 1000W. A step of a few watts rarely changes your day, but the 1200W figure is the one to note if you reheat dense leftovers often. Also watch the electrical draw — the Café lists 1500 watts, so the circuit needs to match.

Final Thoughts: The Verdict
For most kitchens, the cabinet microwave winner is the Frigidaire Gallery Series GMBS3068BF because it delivers the largest interior here at 2.2 cu. ft. with automatic sensor cooking, and it is the crowd favorite at 4.5+ stars across 280+ owners. If you want the trim kit in the box and a higher 1200W output, the Summit SMBI27TK27 is the pick. And if you want your counter back with a quiet pull-out, the KoolMore KM-MD-1SS is the drawer to reach for. Measure your cutout twice and order the matching trim kit before install day.
