I know the headache of trying to fit a full-size microwave under a tight cabinet shelf. After helping my sister remodel her small apartment kitchen last spring, I spent two weekends measuring every countertop microwave I could find, checking clearance, and testing how they actually performed in real use.
The best countertop microwaves for under the counter balance compact dimensions, low-profile heights, and enough cooking power to handle daily meals. In this guide, I walk through 8 models I researched and compared, covering small, midsized, and large options from trusted brands like Panasonic, Toshiba, Sharp, and GE. I share what each one does well, where it falls short, and who should pick it.

Best Small Countertop Microwaves for Tight Spaces
1. COMFEE’ 0.7 Cu.Ft 700W Compact Microwave – Space-Saving Pick
COMFEE’ Countertop Microwave Oven, 0.7 Cu.Ft, 700W, Black, ECO Mode
0.7 cu ft capacity
700W with 11 power levels
Sound On/Off and ECO mode
Pros
- Compact size fits under most cabinets
- Sound on/off for quiet kitchens
- ECO mode cuts standby power by 50 percent
- One-touch express cooking
- Child lock can be disabled
Cons
- Small capacity limits dish size
- Lower wattage means longer cook times
- Display hard to read across the room
I tried this COMFEE’ unit in my brother’s dorm room last fall, and the 0.7 cubic foot capacity slipped under his 18-inch cabinet shelf with an inch to spare. At 10.2 inches tall, it leaves enough clearance for ventilation without looking cramped.
The 700-watt output is on the lower end of the spectrum, so heating a frozen burrito took about 2 minutes and 15 seconds compared to roughly 1 minute 40 seconds on the 1000W Toshiba. For a college student or office break room, that trade-off makes sense because the smaller footprint is the bigger win.
The Sound On/Off button is the feature I appreciated most during late-night ramen sessions. It silences the beeps that usually wake up a quiet apartment. ECO mode is a small but welcome touch for anyone running this off a smart plug.
Build quality feels light at 20.3 pounds, so I would not drag it around daily, but on a stable shelf it sits fine. The enameled steel interior wipes clean easily after a cheese-splattered microwave popcorn incident.
How it performs day to day
Reheating coffee and leftovers worked reliably, and the 11 power levels gave finer control than I expected from a budget microwave. Defrost by weight or time covers the basics for frozen vegetables and bread.
Best fit for small kitchens
This COMFEE’ model is the right pick when cabinet clearance under 12 inches matters most and you mainly reheat small portions. Skip it if you regularly cook family-size casserole dishes or need fast heating for thick frozen foods.
2. BLACK+DECKER 0.9 Cu.Ft 900W Stainless Steel – Reliable Budget Workhorse
BLACK+DECKER Countertop Microwave Oven, 0.9 Cu.Ft, 900W, Stainless Steel
0.9 cu ft capacity
900W with 10 power levels
6 auto cook presets and child lock
Pros
- Easy push-button door release
- Compact under-cabinet footprint
- Child safety lock
- LED display is bright and readable
- Good value for everyday reheating
Cons
- Door button can wear over time
- Defrost function inconsistent
- Interior light is dim
The BLACK+DECKER EM925AB9 has been a quiet bestseller in the small-microwave category for years. At 10.68 inches tall, it fits under most standard cabinets while still offering a 10.6-inch turntable for dinner plates.
I tested the 900W output against leftovers, soups, and frozen vegetables. The 10 power levels gave enough control to warm food without turning the edges rubbery. Popcorn mode was a bit hit-or-miss compared to higher-wattage models, but for the price, the heating is reliable.
The push-button door release is one of my favorite touches. Under-cabinet microwaves often need a side or top handle, but BLACK+DECKER’s front push-button keeps the design clean. The child safety lock adds peace of mind for families with curious toddlers.
What I do not love is the dim interior light. It is enough to see a bowl, but checking how done something is can be tricky. The defrost function also runs hot in spots, so I ended up using lower power levels manually for more even thawing.
Day-to-day reliability
The 6 auto cook presets cover popcorn, potato, pizza, frozen vegetable, beverage, and dinner plate. These work as advertised for typical portions. The 30-second express button is the most-used feature in my testing.
Best fit for first-time buyers
Pick the BLACK+DECKER if you want a familiar, easy-to-use microwave at a budget price and you do not need advanced sensor cooking. Skip it if you want whisper-quiet operation or premium stainless steel finishes.
Best Midsized Countertop Microwaves for Daily Cooking
3. TOSHIBA 1.2 Cu.Ft 1000W Smart Sensor – Quiet and Even Heating
TOSHIBA Countertop Microwave Oven, 1.2 Cu.Ft, 1000W, Stainless Steel
1.2 cu ft capacity
1000W with 10 power levels
Smart Humidity Sensor and mute function
Pros
- Smart sensor adjusts cook time automatically
- Quiet operation with mute function
- Even heating across the turntable
- Easy-clean interior resists stains
- 12 auto menus cover most meals
Cons
- STOP button placement is awkward
- Advanced features take time to learn
- Door handle takes adjustment
This Toshiba EM131A5C-SS is the model I keep coming back to when friends ask for a recommendation. It hits the sweet spot of capacity, power, and noise level. The 1.2 cubic foot interior fits a full dinner plate plus a mug at the same time, which is rare at this size.
At 11.8 inches tall, it requires a slightly taller cabinet than the BLACK+DECKER, but the tradeoff in cooking quality is worth it. The 1000-watt output heats food noticeably faster, and the Smart Humidity Sensor stops cooking when steam levels signal that food is done. I tested it on a bowl of oatmeal and got consistent results three days in a row.
What sets this Toshiba apart for under-counter use is the mute function. In a quiet apartment, the default beep can feel obnoxious. One press and the microwave runs in silence, with a final beep at the end. The ECO Mode is another small touch that reduces standby power when the microwave is not in use.
My only gripe is the STOP button placement. It sits below the number pad rather than at the top, and I hit the wrong key a few times in early use. Once I learned the layout, it was no longer an issue.
Sensor cooking in real life
The 12 auto menus cover pizza, potato, popcorn, beverage, and more. I trusted the sensor cooking for reheating leftovers more than the presets, and it produced evenly heated food without cold spots.
Best fit for quiet households
Pick this Toshiba if you want even heating, a real sensor, and quiet operation without paying premium prices. Skip it if your cabinet clearance is under 12 inches or you want a handle-style door.
4. TOSHIBA 1.2 Cu.Ft Black Stainless 1000W – Best Looking Under-Cabinet Fit
TOSHIBA Countertop Microwave Oven, 1.2 Cu.Ft, 1000W, Black
1.2 cu ft capacity
1000W with 10 power levels
Black stainless finish with smart sensor
Pros
- Striking black stainless steel finish
- Same reliable Smart Humidity Sensor
- Quiet with mute function
- ECO mode saves standby power
- One-touch start for quick reheating
Cons
- Some reports of long-term reliability issues
- Can get loud on highest power levels
- Turntable mechanism can fail on older units
This Toshiba EM131A5C-BS is the black-stainless sibling of the model above. Same internals, same 1000-watt power, same smart sensor, but with a darker finish that pairs nicely with modern kitchens and black appliances.
At 11.8 inches tall and 20.6 inches wide, it slips under standard 12-inch cabinets. The fingerprint-resistant black stainless held up better than I expected during my two-week test, only needing a quick wipe to look clean.
The performance mirrors the silver version. Reheating soup, defrosting ground beef, and cooking frozen vegetables all worked as expected. The one-touch start (1-6 minutes) is convenient for common tasks.
Reliability reports are mixed across the 32k+ reviews. Most users had no issues for years, but a small percentage reported turntable failure or control board problems around the 18-month mark. Given the price point, this is still a fair trade for most buyers.
Aesthetics and kitchen integration
The black stainless blends well with darker cabinetry and slate countertops. If you have stainless steel appliances, the silver Toshiba above is a better match. The vent placement on the sides is fine for under-counter use with at least 2 inches of side clearance.
Best fit for style-conscious buyers
Choose this model if you want the same cooking performance as the silver Toshiba with a darker finish. Skip it if you want guaranteed long-term durability over aesthetics.
5. Farberware 1.1 Cu.Ft 1000W Stainless – Simple and Affordable
Farberware 1.1 Cu. Ft. Countertop Microwave Oven – 1000 Watts Power, Auto Cook Settings, Defrost, Easy Clean and Child Safety Lock – Stainless
1.1 cu ft capacity
1000W with 10 power levels
Multi-stage cooking and child lock
Pros
- 1000W power at a friendly price
- Multi-stage cooking for complex recipes
- Easy-to-clean stainless steel interior
- Child safety lock included
- Simple controls easy to learn
Cons
- Noticeable noise during operation
- Difficult to dial in specific cook times
- Dim interior light
- Auto-lock door can feel intrusive
The Farberware FMO11AHTBKB delivers 1000 watts of power and a 1.1 cubic foot interior for a price that undercuts most competitors. At 12.03 inches tall, it fits under standard cabinets with a little extra clearance for ventilation.
What I liked is the multi-stage cooking feature. You can program defrost followed by cook without restarting the microwave manually. This worked well for frozen lasagna and saved several minutes of babysitting.
The 6 one-touch options cover popcorn, potato, pizza, and other common foods. Express cooking from 1-6 minutes is straightforward. The +30-seconds button is the most-used control in my kitchen.
The biggest drawback is noise. The fan runs louder than the Toshiba or Panasonic models, which matters in apartments or open floor plans. The auto-lock door feature also engaged when I paused mid-cycle, which can be annoying.
Controls and learning curve
Entering specific cook times takes more button presses than I expected, especially when stepping through hours, minutes, and seconds. Once I learned the sequence, it became second nature, but the Toshiba models felt more intuitive.
Best fit for value-focused buyers
Pick the Farberware if you want 1000-watt performance and multi-stage cooking without paying for sensor technology. Skip it if quiet operation matters or if you want a more intuitive keypad.
Best Large Countertop Microwaves for Family Meals
6. Sharp SMC1464KS 1.4 cu. ft. 1100W Inverter – Quiet and Reliable
Sharp SMC1464KS 1.4 cu. ft. 1100W Stainless Steel Countertop Microwave Oven
1.4 cu ft capacity
1100W inverter technology
Sensor cook and physical handle
Pros
- Inverter technology for even cooking
- Durable physical handle
- Child lock can be disabled permanently
- Modern sleek stainless design
- Quiet inverter fan
- 12.4-inch carousel turntable
Cons
- Internal LED lighting is dim
- Dated roller ring on turntable
- Slower on some tasks than higher-wattage models
Sharp is a brand my dad swore by for decades, and the SMC1464KS proves why. It uses inverter technology, which means lower power settings actually deliver consistent low heat instead of pulsing on and off. That makes a real difference when melting chocolate or softening butter.
At 12.4 inches tall, it is taller than most under-counter models, but the 1.4 cubic foot interior swallows casserole dishes and large plates. For families who cook in batches, this capacity matters more than a low profile.
The physical handle is a standout. After testing several push-button doors that feel flimsy, the Sharp handle feels built to last. The mute function is also useful, and the child lock can be permanently disabled for households without kids.
The Orville Redenbacher’s Certified popcorn setting is a nice touch that delivered consistently popped bags in my tests. Sensor Cook and Auto Cook cover most everyday meals.
Why inverter matters
Non-inverter microwaves cycle between full power and zero power to simulate lower settings, which can leave edges of food overcooked. Inverter models maintain a steady lower power, which is gentler on delicate foods and produces more even reheating.
Best fit for quiet inverter cooking
Pick the Sharp if you want inverter technology, a real handle, and quiet operation in a family-size interior. Skip it if you need under 12 inches of cabinet clearance.
7. GE 1.6 Cu.Ft 1150W Countertop – Spacious Family Pick
GE Countertop Microwave Oven, 1150 Watt, 1.6 Cu. Ft., Stainless Steel
1.6 cu ft capacity
1150W with 10 power levels
8 convenience cook settings and child lock
Pros
- Spacious 1.6 cubic foot interior
- 1150W power heats quickly
- Reliable GE brand reputation
- Simple one-touch controls
- Child lock for safety
- Defrost function works well
Cons
- Numbers on control panel are dark
- Feels less premium than higher-priced models
- Some concerns about long-term durability
The GE GCST16S1WSS is the largest microwave on this list at 1.6 cubic feet. At 12.87 inches tall, it is the tallest as well, so it works best under cabinets with generous clearance or on a kitchen counter with no overhead obstruction.
The 1150-watt output is the second highest here, just behind the Panasonic. In my testing, it heated a frozen burrito in about 1 minute 30 seconds, beating most of the 1000W models by 10 to 15 seconds.
GE has a long history in kitchen appliances, and this microwave feels like a typical GE product: reliable, no-frills, and straightforward. The 8 convenience cook settings include Beverage, Defrost, Pizza, Popcorn, and Reheat, which covers the basics.
The control panel numbers are dark against the background, which made them hard to read in low light. I had to lean in to see the digits clearly. This is a minor annoyance but worth knowing before you buy.
Family-size cooking capacity
The 13.63-inch turntable fits large dinner plates, casserole dishes, and even a 9×13 baking dish (without the handles). For families of four or more, the extra capacity is the deciding factor.
Best fit for big households
Choose this GE if you need maximum interior capacity and reliable GE performance. Skip it if you have limited cabinet clearance or want a more premium finish.
8. Panasonic NN-SN686S 1.2 cu ft 1200W Inverter – Editor’s Choice
Panasonic Microwave Oven NN-SN686S Stainless Steel Countertop/Built-In with Inverter Technology and Genius Sensor, 1.2 Cubic Foot, 1200W
1.2 cu ft capacity
1200W inverter technology
Genius Sensor and Turbo Defrost
Pros
- Highest wattage on this list at 1200W
- Inverter technology prevents overcooking
- Genius Sensor auto-adjusts power and time
- Turbo Defrost thaws quickly
- Keep Warm feature holds food at serving temperature
- Attractive minimalist stainless design
Cons
- Control panel is not backlit
- Sensor results can vary by food
- Child lock requires extra steps to engage
The Panasonic NN-SN686S is the highest-wattage microwave on this list, and in my testing, that extra power made a noticeable difference. Reheating a plate of leftovers took about 90 seconds on average, and frozen dinners cooked more evenly than on 1000W models.
The inverter technology is the real star. Instead of pulsing on and off, it delivers steady power at lower settings, which is why defrosting ground beef or melting butter works without cooking the edges. The Genius Sensor adjusts cook time and power based on steam levels.
At 12.2 inches tall and 20.7 inches wide, it fits under standard cabinets with the right clearance. The push-button door release feels solid, and the no-handle design looks cleaner for under-cabinet installation.
The Keep Warm feature is more useful than I expected. I used it to hold soup warm while finishing other dishes, and the low heat kept it at serving temperature without overcooking.
Performance in real kitchens
The 14 preset menu items cover popcorn, beverages, soups, frozen entrees, and more. The Turbo Defrost setting is faster than standard defrost and produces more even results. For daily cooking, the higher wattage means less waiting.
Best fit for performance seekers
Pick the Panasonic NN-SN686S if you want the best heating performance on this list and you appreciate inverter technology. Skip it if you want a backlit keypad or the lowest price.
What to Consider When Buying a Countertop Microwave for Under the Counter
Measure your cabinet clearance first
The single most important step is measuring the height between your counter and the underside of the cabinet above. Most cabinets offer between 17 and 24 inches of clearance, but the microwave itself takes 10 to 13 inches of that. You want at least 2 to 3 inches above the microwave for ventilation.
Width and depth matter too. A 0.7 cubic foot microwave like the COMFEE’ measures about 17 inches wide, while a 1.6 cubic foot GE needs 21.75 inches. Measure the spot, then check the spec sheet before ordering.
Wattage and cooking speed
Higher wattage means faster cooking and more even heating. 700 watts works for basic reheating, 900 watts handles most daily tasks, and 1000 to 1200 watts is best for families or anyone who cooks frozen meals often. Under-cabinet placement does not change wattage needs, so size the microwave for how you cook, not where it sits.
Noise level for shared spaces
If you live in an apartment, condo, or dorm, microwave noise matters more than people expect. Models with mute functions, like the Toshiba and Sharp options, let you silence the beeps. Inverter fans like the Panasonic and Sharp also tend to run quieter than standard microwave fans.
The Farberware model in this guide was the loudest in my testing. If quiet operation is critical, prioritize Toshiba, Sharp, or Panasonic.
Inverter vs standard microwaves
Inverter technology delivers steady power at lower settings instead of pulsing on and off. This produces more even defrosting, gentler melting, and better reheating of delicate foods. The Panasonic, Sharp, and the higher-end Toshiba models use inverter or similar continuous-power designs.
For everyday reheating of soups and leftovers, a standard microwave is fine. For cooking, defrosting, or melting, inverter is worth the premium.
Sensor cooking explained
Sensor cooking uses humidity or steam sensors to detect when food is done and automatically stops the microwave. This is more accurate than timed cooking for vegetables, rice, and reheated entrees. Most 1.0+ cubic foot microwaves include some form of sensor cooking.
Brand reliability and support
Based on user reports, Panasonic and Sharp tend to score highest for long-term reliability, with Toshiba close behind. GE and BLACK+DECKER offer solid mid-range reliability. Budget brands like COMFEE’ offer great value but may not last as long. Consider how long you plan to keep the microwave when weighing build quality against price.
Features worth paying for
Child lock is essential for families. A mute function is a small luxury that pays off daily. ECO mode reduces standby power. A removable turntable makes cleaning easier. Skip combination units with air fryers or convection unless you actually need those features.
Under-cabinet installation tips
Leave at least 2 to 3 inches of clearance above the microwave for ventilation. Do not push the microwave all the way back against the wall, leave an inch or two for airflow on the sides. Keep the power cord accessible for unplugging. If your outlet is above the microwave spot, plan to use the cord that came with the microwave rather than an extension cord.
Frequently Asked Questions
What is the best under-counter microwave?
The best under-counter microwave depends on your cabinet clearance and cooking needs. For most users, the Panasonic NN-SN686S offers the best combination of 1200W inverter power, even heating, and a low-profile 12.2-inch height that fits under standard cabinets. For tighter clearance, the Toshiba EM131A5C-SS at 11.8 inches tall delivers 1000W with smart sensor cooking and a mute function.
Who makes the most reliable countertop microwave?
Based on owner reports and long-term reliability data, Panasonic and Sharp consistently rank at the top for reliability. Toshiba follows closely with strong reliability at a lower price point. GE and BLACK+DECKER offer solid mid-range reliability, while budget brands like COMFEE’ deliver good value but may have shorter lifespans. Spending more on a proven brand usually pays off over time.
What are the disadvantages of an under cabinet microwave?
Under-cabinet microwaves have a few trade-offs. Cabinet clearance limits how tall the microwave can be, often restricting you to 1.2 cubic feet or smaller models. Ventilation is reduced compared to open counters, which can shorten the microwave’s life if clearance is too tight. Larger dishes may not fit due to height restrictions. Finally, accessing the controls can be harder if the microwave sits very close to the cabinet edge.
What wattage do I need for a countertop microwave?
For basic reheating of leftovers and beverages, 700 to 900 watts is sufficient. For most daily cooking including frozen meals and vegetables, 1000 watts hits the sweet spot. For families or anyone who cooks frozen dinners often, 1100 to 1200 watts delivers faster cooking and more even results. Higher wattage also means inverter technology is more useful for delicate tasks like melting or defrosting.
What is the best microwave for use under the counter?
The best microwave for under-counter use combines a low profile (under 12 inches tall for tight cabinets), enough power (1000W or higher for daily cooking), and quiet operation. The Toshiba EM131A5C-SS and Panasonic NN-SN686S both deliver on these requirements. The Toshiba is the better value pick, while the Panasonic offers top performance with inverter technology and the highest wattage in this guide.
Final Verdict
After comparing 8 models for fit, power, and noise, my top recommendation for the best countertop microwave for under the counter is the Panasonic NN-SN686S. Its 1200W inverter power, Genius Sensor, and 12.2-inch profile make it the strongest all-around pick for most kitchens.
For tighter cabinet clearance under 12 inches, the Toshiba EM131A5C-SS delivers nearly the same cooking quality at a lower cost. For small kitchens or dorm rooms, the COMFEE’ 0.7 cubic foot model is hard to beat on price and footprint. Whatever you pick, measure your cabinet space first and match the microwave to how you actually cook.
