9 Best Inbuilt Microwave | Inbuilt Microwave Guide

Choosing an inbuilt microwave means committing to a permanent fixture that should match your cabinetry, cooking habits, and counter space constraints for years. The difference between a seamless installation and a frustrating retrofit often comes down to trim kit compatibility and cutout dimensions measured in fractions of an inch.

I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I’ve spent years analyzing built-in kitchen appliance specifications, comparing wattage outputs, cavity sizes, and installation requirements so you can make a confident purchase the first time.

A well-researched inbuilt microwave delivers consistent reheating, saves valuable counter space, and integrates flush with your kitchen design — no exposed cords, no crowded surfaces.

How To Choose The Best Inbuilt Microwave

Built-in microwaves are not one-size-fits-all. The wrong dimension or trim kit can turn a simple install into a costly cabinet modification. Focus on cutout size, intended location (under cabinet, over wall oven, or drawer under counter), and whether you need extra functions like convection or air frying.

Cutout Dimensions and Trim Kit Compatibility

Every inbuilt microwave requires precise cabinet opening dimensions. A 27-inch wide trim kit fits a different opening than a 30-inch trim kit. Always measure your existing cutout height, width, and depth before browsing. Trim kits cover raw edges but cannot bridge gaps larger than a fraction of an inch.

Convection, Broil, or Standard Microwave

Standard inbuilt microwaves handle reheating and defrosting reliably. Convection models add a fan-forced heating element that browns, bakes, and roasts. Some units also offer broil or integrated air fryer functionality. Decide whether you need a dedicated microwave or a multi-cook hybrid that can replace secondary appliances.

Drawer-Style vs. Door-Style Installation

Drawer microwaves pull out like a drawer, eliminating the need to reach over hot cooktops or bend down low. They fit under countertops or below wall ovens and offer easy access for children and users with mobility concerns. Door-style built-in units usually install above counter height or in a wall cavity — choose based on your kitchen ergonomics and cabinet layout.

Best Overall

1. Frigidaire Gallery Series GMBS3068BF

2.2 cu.ft.Trim kit sold separately

Frigidaire’s Gallery Series GMBS3068BF delivers a generous 2.2 cubic foot cavity that fits large platters and casserole dishes without turning the turntable into a bottleneck. The interior height accommodates taller containers that smaller built-in units simply cannot hold, making this a strong choice for families who reheat full-size meals regularly.

The 1,200-watt output ensures rapid heating and even results across multiple power levels. Installation requires purchasing a separate trim kit to match your cabinet finish, so factor that into your total budget. The stainless steel exterior resists fingerprints better than raw stainless, maintaining a clean look in high-traffic kitchens.

Sensor cooking and reheat functions automatically adjust time and power based on humidity levels inside the cavity. This reduces the guesswork of reheating leftovers or defrosting meats. The control panel layout is straightforward with clearly labeled presets for popcorn, pizza, and beverages.

Why it’s great

  • Roomiest cavity in this roundup at 2.2 cu.ft.
  • 1,200W heating power for fast results
  • Fingerprint-resistant stainless steel finish

Good to know

  • Trim kit must be purchased separately
  • No convection or broil functionality

2. Summit Built-in Microwave with Trim Kit SMBI27TK27

Includes trim kit27-inch fit

The Summit SMBI27TK27 ships with a stainless steel trim kit designed to fit 27-inch wide cabinet openings, eliminating the hassle of sourcing a separate trim piece. The unit itself is sized at 24 3/8 inches wide, and the included trim bridges the gap cleanly up to 26 7/8 inches. This makes it a plug-and-play solution for standard 27-inch cutout spaces.

With 1,200 watts and a 2.2 cubic foot capacity, this microwave rivals countertop units in power while integrating flush into your cabinetry. The multiple power levels include dedicated presets for popcorn, pizza, and beverages, plus defrost by weight or time. Multistage cooking lets you program defrost followed by cook in a single sequence.

The installation flexibility stands out — it can be mounted above or below the counter, or over a wall oven. A child lock prevents unintended use. At 75 pounds total weight including the trim kit, professional installation or an extra set of hands is recommended when positioning into the cabinet opening.

Why it’s great

  • Trim kit included — no extra purchase needed
  • 1200W power with 2.2 cu.ft. interior
  • Multistage cooking sequences

Good to know

  • Heavy unit requires careful installation
  • No convection or sensor cooking
Convection Hybrid

3. Gasland 24 Inch Built-in Microwave and Convection Oven Combination

1.6 cu.ft.Soft-close door

Gasland combines a 1,000-watt microwave with a convection oven in a 24-inch wide chassis, making it ideal for compact kitchens that still want baking capability. The 3D convection system circulates hot air evenly through the 1.6 cubic foot cavity, reducing cold spots and cooking time for items like roasted vegetables or frozen pizzas that benefit from dry heat.

Eight auto cook programs cover popcorn, pizza, beverage, sensor cook, sensor reheat, auto defrost, frozen foods, and an auto menu. The soft-close door mechanism prevents loud slams and reduces wear on the hinges over time. Cool Door technology uses a triple-layer tempered glass panel that stays safe to touch on the outside even during extended convection cycles.

The stainless steel exterior and LCD touch control panel present a modern aesthetic. Note that the control panel ships with a protective film that should be peeled off after installation. This unit requires a dedicated 120V circuit and professional installation to ensure proper ventilation alignment.

Why it’s great

  • Microwave and convection in one 24-inch unit
  • Soft-close door with triple-layer glass
  • 8 one-touch auto cook programs

Good to know

  • Installation requires precise 24-inch cutout
  • No dedicated air fryer function
Broil Ready

4. KoolMore 24 Inch Built-in Convection Oven and Microwave Combination KM-CWO24-SS

Supports broiling66-lb door rating

KoolMore’s KM-CWO24-SS adds broil capability alongside convection and standard microwave modes, giving you the ability to brown casseroles and melt cheese without transferring dishes to a separate oven. The top and bottom heating elements paired with a fan distribute heat for even baking through the 1.5 cubic foot cavity.

A reinforced door hinge supports up to 66 pounds resting on the open door, which is useful when sliding heavy roasters or pans in and out. Cool Door technology uses double-layered glass to keep the exterior surface safe. The soft-close mechanism reduces noise and protects fingers during everyday use.

Pre-set cooking timers handle common foods like frozen entrees and potatoes automatically. The stainless steel interior resists staining and simplifies cleaning. This unit fits a standard 24-inch cabinet opening but always measure your exact cutout depth — the product dimensions are 22.3 inches deep, which may exceed shallow cabinets.

Why it’s great

  • Broil, convection, and microwave in one
  • Door supports up to 66 lbs when open
  • Double-layered cool-touch exterior glass

Good to know

  • 1.5 cu.ft. cavity smaller than some competitors
  • Depth may be tight for shallow cabinets
Air Fry Combo

5. KoolMore 30 in. Built-in Microwave with Convection Oven and Air Fryer KM-CWO30-SS

30-inch fitAir fryer function

KoolMore’s 30-inch KM-CWO30-SS integrates air fryer capability directly into the built-in microwave platform, allowing you to crisp french fries, chicken wings, and vegetables using circulated hot air rather than deep frying. The 1,000-watt microwave mode handles standard reheating while the convection fan and heating element manage air frying and baking tasks.

The 1.6 cubic foot interior provides ample space for a whole chicken or a large baking sheet. The button control interface is straightforward, though it lacks the touchscreen precision found on higher-end drawer units. Manual defrost requires setting time and power level yourself rather than relying on an auto-sensor.

Built-in installation integrates seamlessly into standard 30-inch wide cabinet openings. The stainless steel interior and exterior make cleanup simple after greasy air fryer sessions. This unit is UL listed for safety compliance. If you want a single appliance that replaces a countertop microwave and a separate air fryer, this hybrid delivers that consolidation.

Why it’s great

  • Built-in microwave with integrated air fryer
  • 1.6 cu.ft. capacity for large dishes
  • UL listed for safety

Good to know

  • Manual defrost only — no auto sensor
  • Button controls instead of touchscreen
Drawer Premium

6. COSMO COS-MWD3012NHSS Haven Collection Drawer Microwave

Drawer styleEco mode

The COSMO Haven Collection COS-MWD3012NHSS brings drawer-style convenience to a 30-inch built-in platform. The pull-out drawer eliminates the need to reach over hot stove tops or bend down low, making it accessible for users of all heights. The 1.2 cubic foot cavity accommodates a 9×13 baking dish without rotating interference.

Ten power levels provide precise control, and the 1,000-watt output handles everything from gentle melting to rapid reheating. Four automatic presets cover melt, soften, popcorn, and beverage functions. The defrost rack included with the unit makes thawing meats and fish more effective by elevating them above collected moisture.

An Eco mode reduces standby power consumption when the microwave is not in use. The exterior dimensions of 29.9 inches wide require a precise 30-inch cabinet opening for flush installation. The one-year limited warranty is backed by a US-based support team, which adds peace of mind for a built-in appliance that must last years.

Why it’s great

  • Drawer-style pull-out for easy access
  • Includes defrost rack for elevated thawing
  • Eco mode reduces standby power draw

Good to know

  • 1.2 cu.ft. cavity is smaller than door-style units
  • No convection or air fryer functionality
Sleek Drawer

7. COSMO COS-MWD3012GSS Haven Collection Drawer Microwave

Handleless designQuiet operation

The COS-MWD3012GSS is nearly identical to the NHSS model but replaces the front handle with a push-to-open interface, giving it a seamless, handleless appearance that suits modern minimalist cabinetry. The drawer glides open smoothly with a touch, and the lack of a protruding handle saves clearance space if your microwave sits next to a door or appliance.

Real user feedback highlights the quiet operation — the unit runs with minimal mechanical noise and includes a mute option to silence beeps entirely. This is a genuine advantage in open-plan kitchens where microwave sounds carry into living areas. The 1,000-watt output and ten power levels deliver performance on par with the NHSS variant.

Sensor reheat and sensor cook programs simplify reheating, though some users noted that the control panel codes (1 = pasta, 2 = pizza) require referencing the manual initially. The stainless steel finish and easy-clean interior are consistent with the Haven Collection line. Installation requires the same 30-inch cabinet opening as the NHSS model.

Why it’s great

  • Handleless push-to-open drawer design
  • Quiet operation with mute option
  • Sensor cooking for hands-off reheating

Good to know

  • Sensor program codes not labeled on panel
  • No convection or air fryer
Smart Drawer

8. Zephyr 30 Inch Built In Drawer Microwave

Touch open/closeSensor cooking

Zephyr’s 30-inch drawer microwave focuses on intuitive interactions with an electronic LCD touch control panel that handles open/close, mute functions, sensor cooking, sensor reheating, control lock, and defrost. The touch open/close feature lets you activate the drawer with a light tap, which is especially convenient when your hands are full with hot dishes.

The 1,000-watt output across ten power levels gives you fine-grained control over cooking intensity. Sensor cook and sensor reheat measure steam and humidity inside the cavity to automatically adjust time and power, reducing the risk of dried-out leftovers. The 1.2 cubic foot cavity is large enough for a 9×13 baking dish, a key requirement for family-sized casseroles.

This unit supports both standard and flush-mount installations for a clean, integrated look in your cabinetry. The stainless steel interior is easy to wipe down, and the included installation kit covers the basic hardware. For a premium drawer experience with touch activation and sensor precision, this Zephyr model competes directly with the higher-end Sharp offering.

Why it’s great

  • Touch-activated drawer open and close
  • Sensor cook and reheat for precise results
  • Fits 9×13 baking dish comfortably

Good to know

  • No convection or air fryer functionality
  • Requires 30-inch cabinet cutout exactly
Angled Control

9. Sharp SMD3070ASY Microwave Drawer Oven

Concealed touch panel950W

Sharp’s SMD3070ASY pioneered the drawer microwave concept and remains a benchmark for this form factor. The concealed angled touch control panel sits at a 45-degree tilt, making it readable and reachable without bending down. When not in use, the panel tucks away behind the drawer front for a clean facade.

The easy-touch automatic drawer system opens smoothly at a press and enables hands-free closing — a useful feature when carrying heavy plates or hot liquids. The 1.2 cubic foot interior fits a 4-quart casserole dish or a 20-ounce beverage container comfortably. At 950 watts, the power output is slightly lower than competing drawer units, but the even distribution and reliable Sharp magnetron maintain consistent heating.

This unit is best for those who prioritize sleek design and drawer ergonomics over maximum wattage or multi-function extras like convection. The stainless steel finish resists smudges and integrates well with professional-grade kitchen suites. Installation requires a 30-inch wide cutout with proper depth clearance of 23 inches.

Why it’s great

  • Concealed 45-degree angled touch panel
  • Hands-free close feature on drawer
  • Trusted Sharp magnetron for even heating

Good to know

  • 950W output is lower than 1000W+ competitors
  • No convection, broil, or air fryer modes

FAQ

Can I install an inbuilt microwave in an existing cabinet space without cutting the opening?
Only if the existing cutout matches the microwave’s installation dimensions exactly. Most built-in microwaves require specific height, width, and depth clearances for proper ventilation. You may need to modify cabinet framing or order a custom trim kit to bridge dimensional gaps.
What is the difference between a drawer microwave and a standard built-in door microwave?
A drawer microwave pulls out like a drawer, allowing you to place food on the turntable without bending or reaching over a hot cooktop. Door-style built-in microwaves open on a hinge and are typically installed above counter height. Drawer units generally have smaller cavities (around 1.2 cu.ft.) compared to door models (up to 2.2 cu.ft.).
Do all inbuilt microwaves require professional installation?
Professional installation is strongly recommended due to the precise cutout requirements, electrical wiring, and venting needs. Some models include detailed installation templates, but errors in alignment can lead to poor fit, overheating, or voided warranties. If you are replacing an existing built-in unit of the same size, installation is more straightforward.
Can a built-in microwave be placed over a gas or electric range?
Some built-in microwaves are rated for installation over a range (over-the-range models) and include integrated ventilation fans. Standard built-in units not designed for over-the-range placement should not be installed above a cooktop. Always check the manufacturer’s installation guidelines for clearance above heat sources.

Final Thoughts: The Verdict

For most users, the inbuilt microwave winner is the Frigidaire Gallery GMBS3068BF because it offers the largest 2.2 cubic foot cavity at 1,200 watts, fitting family-sized dishes without compromising heating speed. If you want a complete kit with trim included for a 27-inch opening, grab the Summit SMBI27TK27. And for under-counter drawer convenience with touch open/close, nothing beats the Zephyr 30 Inch Drawer Microwave.
