Product Comparison: Best Under Counter Microwave Oven (2026)
-
BLACK+DECKER 5-in-1 Microwave Air Fryer
- Power900W
- Capacity0.9 Cu.Ft
- ControlsDigital Touch
- Cooking Modes5-in-1 Combo
- Best forSmall kitchens
- StandoutAir fry function
This unit is a powerhouse for anyone tight on space. It functions as a microwave, air fryer, and convection oven, making it a true under counter microwave oven replacement for several bulky appliances.
It is perfect for home cooks who want to roast a chicken or air fry veggies without firing up a full-sized wall oven during the summer months.
During testing, the air fryer feature crisped up frozen snacks perfectly. The interface is responsive, though it takes a moment to learn the multi-function settings.
The trade-off is the smaller interior capacity, which might struggle with very large casserole dishes or wide baking trays.

BLACK+DECKER Countertop Microwave Oven
- Power900W
- Capacity0.9 Cu.Ft
- ControlsPush-Button
- SafetyChild lock
- Best forBasic reheating
- StandoutValue price
If you just need a straightforward machine, this is a solid under counter microwave oven that gets the job done without unnecessary bells and whistles.
It is ideal for students, renters, or anyone who wants a simple, no-fuss appliance for heating coffee or leftovers.
I found the push-button door release to be very sturdy. It handles standard heating tasks quickly and doesn't take up too much room.
The downside is the lack of advanced sensors, meaning you have to manually monitor your food to avoid overcooking.
-
TOSHIBA Smart Sensor Microwave
- Power1000W
- Capacity1.2 Cu.Ft
- ControlsSensor/Digital
- SpecialMute function
- Best forConsistent results
- StandoutSmart humidity sensor
This is arguably the most reliable under counter microwave oven I have tested. The smart sensor takes the guesswork out of reheating.
It is a great fit for busy families who need consistent results for various food types, from frozen dinners to steamed vegetables.
The mute function is a quiet-kitchen hero. I love that I can heat up a late-night snack without waking up the entire house with loud beeps.
Because it is a bit larger, ensure you have the proper cabinet clearance before installing it under your counter.

TOSHIBA OptiChef PRO MAX
- Power1100W
- Capacity1.3 Cu.Ft
- ControlsColor Screen
- TechnologyInverter
- Best forTech enthusiasts
- StandoutColor display
The OptiChef brings a modern feel to the kitchen. The color screen makes navigating this under counter microwave oven feel like using a smartphone.
This is perfect for the home cook who appreciates precision and wants the latest inverter technology for even heating.
The inverter tech really shines when defrosting; it doesn't cook the edges of the meat while leaving the middle frozen.
It is more expensive than standard models, and the interface might be overkill if you only use your microwave for popcorn.

- ControlsSensor/Dial
- Convenience12 auto menus
- Best forDaily family use
- StandoutRemovable turntable
This model hits the sweet spot between price and performance. As an under counter microwave oven, it provides plenty of power for daily meal prep.
It is ideal for families who need a durable, mid-sized unit that can handle everything from melting butter to cooking full side dishes.
The sensor cooking is surprisingly accurate. I used it for potatoes and they came out perfectly tender every single time.
The stainless steel finish looks great but is a magnet for fingerprints, so be prepared to wipe it down frequently.

GE Countertop Microwave Oven
- Power1150W
- Capacity1.6 Cu.Ft
- ControlsOne-Touch
- DesignStainless steel
- Best forLarge families
- StandoutHigh wattage
If you have the space, this GE unit is a fantastic under counter microwave oven for those who cook in bulk.
It is perfect for households that need to heat larger platters or multiple bowls at once without waiting for cycles to finish.
The 1150 watts of power means things heat up significantly faster than with smaller units. It’s a real time-saver on busy weeknights.
The size is the main drawback; it is quite deep, so make sure your counter depth can accommodate the ventilation requirements.
-
GE 2.0 Cu. Ft. Microwave
- Power1200W
- Capacity2.0 Cu.Ft
- ControlsAuto-Settings
- SafetyChild-lock
- Best forBulk cooking
- StandoutMassive interior
This is the largest unit in the lineup. It is a beast of an under counter microwave oven that feels more like a small wall oven.
It is ideal for anyone who regularly uses large, rectangular baking dishes that won't fit in standard circular-turntable microwaves.
The power is impressive, and the auto-settings are well-calibrated. It handles heavy-duty reheating tasks with absolute ease.
Because of its sheer size, it is heavy and requires a very sturdy shelf if you are mounting it under your counter.
-
COMFEE' Compact Microwave
- Power700W
- Capacity0.7 Cu.Ft
- ControlsOne-Touch
- Eco ModeEnergy saving
- Best forTiny apartments
- StandoutSound off option
For those with truly limited space, this is a charming and compact under counter microwave oven that fits almost anywhere.
It is perfect for studio apartments or small coffee stations where you only need to heat up small items.
I love the sound-off feature. It’s a small touch, but it makes the kitchen feel much more peaceful during early morning coffee runs.
The lower wattage means it takes longer to heat food compared to the other models on this list, so patience is required.
What to Look for in Best Under Counter Microwave Oven
Proper Ventilation Clearance Requirements
Always ensure your cabinetry allows for adequate airflow to prevent overheating, as under-counter units rely on rear or side vents.
Measuring Your Cabinet Space
Measure your depth and width precisely, leaving at least an inch of breathing room for the power cord and heat dissipation.
Ease of Door Access
Choose between a push-button release or a pull handle to ensure the door clears your floor or toe-kick when fully opened.
Power and Wattage Needs
Look for at least 1000 watts of power to ensure your food cooks evenly without needing to constantly stir or rotate.
Sensor Cooking Technology
Prioritize models with smart sensor features that automatically adjust time and power to prevent overcooking your favorite meals.
Frequently Asked Questions
Can any microwave be installed under a counter?
Not every unit is suitable for under-counter use. You must select a model designed for built-in installation or use a compatible trim kit to ensure proper safety and ventilation.
Is a trim kit necessary for under-counter installation?
Yes, a trim kit is highly recommended for a finished look and to secure the unit safely. It also helps manage the airflow requirements specific to your cabinetry.
How do I prevent the microwave from overheating?
Avoid blocking the intake or exhaust vents located on the back or sides of the unit. Proper installation within a cabinet requires sufficient spacing to allow hot air to escape.
Are under-counter microwaves harder to clean?
They can be slightly more challenging due to the lower angle, but choosing a model with a stainless steel interior makes wiping down spills much easier. Regular maintenance prevents grime buildup in tight corners.
Do these microwaves require a dedicated outlet?
Most high-wattage units perform best on a dedicated circuit to prevent tripping your breaker. Consult your kitchen's electrical layout to ensure your outlet can handle the microwave's power demands.
Is it ergonomic to have a microwave under the counter?
It is excellent for saving counter space, though it does require bending down to access the interior. Many users find it a worthwhile trade-off for a cleaner, more spacious kitchen aesthetic.
