Best Undercabinet Microwave Reviews and Ratings
An undercabinet microwave is one of the most space-saving upgrades a home cook can make, and it’s quickly becoming a staple in modern kitchens of all sizes. For anyone juggling limited counter space, busy mornings, or a desire to keep things tidy, this compact appliance delivers serious convenience without sacrificing functionality. In this roundup of the top 10 undercabinet microwave options, we’ve tested performance, build quality, and real-world usability so you can find the best fit for your cooking style and budget. Whether you’re reheating leftovers, popping popcorn, or defrosting dinner, these picks cover every need and price point.
1. BLACK+DECKER 0.7 Cu.Ft. Stainless Steel Microwave
Reheating leftovers without tying up the stove should be simple, and the BLACK+DECKER 0.7 Cu.Ft. Stainless Steel Microwave makes that routine less of a chore. Its 700-watt power suits quick lunches, drinks, frozen snacks, and small portions, while the compact footprint works well on a busy counter or a narrow shelf.
The stainless-steel exterior gives the appliance a clean, durable-looking finish that coordinates easily with common kitchen appliances. Straightforward daily operation is useful for anyone who does not want to navigate a dense display, and the roomy door area makes checking and removing food more convenient. It is a practical choice for an office break room, apartment, or second kitchen.
Because capacity is modest, it is best suited to smaller plates and individual dishes rather than large casseroles. Users wanting to free up counter space can place it on a shelf with adequate ventilation, but measurements should be checked first. Overall, it delivers the core functions of a basic microwave in a relatively compact package.
- Compact 0.7-cu.-ft. capacity
- 700 watts for everyday reheating
- Stainless-steel finish coordinates easily
- Suitable for apartments and offices
- Straightforward cooking interface
- Limited room for larger dishes
- Installation space must allow proper ventilation

2. TOSHIBA 1.2 Cu.Ft. Stainless Steel Microwave Oven
The TOSHIBA 1.2 Cu.Ft. Stainless Steel Microwave Oven is ideal for busy households that want more room than a mini microwave without moving up to a bulky full-size model. Its 1000-watt rating and generous capacity should suit everyday family portions, from reheating dinner plates to preparing drinks, popcorn, and frozen foods.
The larger interior makes it more practical for square dishes, serving bowls, and moderately sized casseroles than many compact models. Its stainless-steel construction gives it a modern, durable appearance that can blend into an updated kitchen. The countertop format also means it can fit a conventional work surface rather than requiring a dedicated built-in opening.
For families, this model offers a useful balance between cooking capability and appliance size. It should handle repeated daily use better than a very small personal microwave, while remaining easier to reposition than a large built-in unit. As with any countertop appliance, leave the required clearance around the cabinet and verify dimensions before ordering.
- Spacious 1.2-cu.-ft. interior
- Powerful 1000-watt rating
- Supports larger everyday dishes
- Attractive stainless-steel exterior
- No built-in installation required
- Bulkier than a compact microwave
- Ventilation clearance is required

3. TOSHIBA Smart Sensor Microwave 1.3 Cu.Ft. Oven
The single standout feature is Sensor Reheat, which gives the TOSHIBA Smart Sensor Microwave 1.3 Cu.Ft. Oven a more hands-off approach to uneven leftovers. Rather than relying only on a guessed time or power level, the sensor is designed to evaluate the food as it heats, helping reduce overcooking, drying, and interrupted meal preparation.
Its 1100-watt power rating provides ample performance for quick breakfasts, frozen foods, reheated meals, and family-size portions. The 1.3-cu.-ft. interior is large enough for useful dish clearance without appearing oversized on a standard counter. This combination is valuable for cooks who frequently bring home leftovers or prepare different foods with varying moisture levels.
Sensor functions are especially helpful when reheating rice, vegetables, casseroles, and plates with mixed hot and cold areas. Although no setting will be perfect for every recipe, automation can make the microwave more approachable for less experienced users. The extra capacity and strong power also make it suitable for families that do not want to heat one small dish at a time.
- Sensor Reheat automates cooking adjustments
- Large 1.3-cu.-ft. capacity
- Powerful 1100-watt rating
- Useful for mixed or uneven foods
- Roomy enough for family portions
- Larger countertop footprint
- Sensor results vary by food and serving

4. KoolMore 1.2 Cu.Ft. Wall-Mounted Microwave Drawer
Unlike a conventional drop-down microwave, which can leave one hand occupied holding its door, the KoolMore 1.2 Cu.Ft. Wall-Mounted Microwave Drawer pulls straight out like a drawer. That horizontal loading style makes it easier to reach into a high or low cabinet placement and keeps the opening clear while food is retrieved.
Ten custom cooking levels provide finer control for people who prepare foods beyond a standard reheating routine. Memory functions can reduce repetitive programming, while the timer adds another layer of everyday convenience. Together, these details are useful in a kitchen where several household members use the microwave and want their preferred settings close at hand.
The 1000-watt power and 1.2-cu.-ft. capacity should handle typical meals without requiring a large over-the-range appliance. A flat-bottom interior also creates a more level place to set down mugs, shallow bowls, and square plates. Since this is a wall-mounted 24-inch unit, cabinet dimensions, support requirements, electrical access, and ventilation must be verified carefully. (See Also:Best Microwave With Buttons Reviews)
- Easy-to-reach drawer loading design
- Ten customizable cooking levels
- Useful memory and timer functions
- Flat-bottom loading surface
- Frees countertop workspace
- Requires careful cabinet planning
- Professional installation may be necessary

5. Sharp SMD2470ASY 1.2 Cu.Ft. Built-In Microwave Drawer
Picture building a coffee station into a kitchen island, with a server opening drawers beneath the counter. The Sharp SMD2470ASY 1.2 Cu.Ft. Built-In Microwave Drawer fits that scenario well because its front-access loading allows users to place and remove tall mugs, bowls, or plates without bending over a traditional countertop microwave or swinging a side-hinged door.
Its 1.2-cu.-ft. interior provides useful room for everyday reheating and beverage preparation, while the built-in format keeps the surrounding cabinetry uncluttered. The drawer presentation also feels natural in contemporary kitchens where appliance doors, warming drawers, and other storage components are aligned beneath counters or in tall cabinetry sections.
Because the microwave is designed for a dedicated cabinet opening, the main consideration is planning rather than day-to-day portability. Homeowners should measure the cavity, confirm the required ventilation clearances, and ensure an appropriate electrical circuit is available. When installed as intended, it is a neat solution for adding full-size microwave capacity without visually interrupting the cabinetry.
- Convenient front-access loading
- Roomy 1.2-cu.-ft. interior
- Seamless built-in cabinetry appearance
- Good for tall mugs and dishes
- Maintains uncluttered countertops
- Requires a properly sized cabinet opening
- Installation needs ventilation and electrical planning

6. GE Compatible Under-Cabinet Microwave Mounting Kit
For the money, the GE Compatible Under-Cabinet Microwave Mounting Kit offers a focused solution: supporting a compatible microwave beneath a cabinet rather than surrendering valuable counter space. It is especially useful when temporary countertop placement would crowd a small kitchen, office pantry, or recreational vehicle, although the included components must match the cabinet and microwave.
A clean installation can make an otherwise inexpensive appliance look purposeful and integrated into the room. Moving the microwave upward keeps the work surface open while placing the appliance within comfortable reach, and it can be useful near a food-preparation area where repeatedly carrying dishes across the kitchen would be inconvenient. The kit gives existing equipment a second placement option.
Compatibility is the decisive concern, not the bracket type or cabinet finish. Buyers should compare the installation instructions with the exact microwave model number, cabinet material, and required mounting surface before purchase. Ceiling strength, electrical routing, and manufacturer-recommended clearances should also be checked. A dedicated mounting kit is still a good value when those conditions align.
- Affordable way to free counter space
- Can reposition a compatible microwave
- Keeps the appliance within easy reach
- Useful in kitchens, offices, and RVs
- Brings a built-in look without buying an oven
- Compatibility depends on exact models
- Safe mounting surface must be verified

7. Summit 24-Inch Built-In Stainless Steel Microwave
A microwave can make an under-cabinet setup look unfinished when the cabinet cutout, wall, or surrounding trim is not framed neatly. The Summit 24-Inch Built-In Stainless Steel Microwave addresses that visual frustration with a coordinated stainless finish and matching trim kit, creating a more intentional built-in appearance than an appliance simply sitting beneath a cabinet.
Installing the trim helps bridge the gap between the microwave and the surrounding surface, so gaps and basic construction are less likely to dominate the area. The stainless finish is a versatile option for modern kitchens and works well with gray, black, or stainless cabinet hardware. This makes the package a practical choice for homeowners upgrading a dated installation.
The 24-inch size should fit many common cabinet openings, but it is not universal. Measurements must cover both the microwave and trim, and installers need to account for ventilation and service access. A microwave alone cannot always compensate for poor cabinet construction, but a well-selected unit and properly fitted trim can make the finished installation look considerably more polished.
- Coordinated stainless-steel appearance
- Matching trim improves visual integration
- Designed for a 24-inch installation
- Neutral finish suits many kitchens
- Potentially cheaper than a larger built-in model
- Cutout dimensions must be measured
- Ventilation and service access remain necessary

8. GE Profile 1.2 Cu.Ft. Low-Profile Over-the-Range Microwave
The GE Profile 1.2 Cu.Ft. Low-Profile Over-the-Range Microwave is ideal for renovators who want a microwave, range hood, and task lighting in one appliance without a deeply projecting hood blocking views across the stove. Its 1.2-cu.-ft. interior remains useful for family reheating, while the slim profile preserves more visual openness in a compact or frequently used kitchen.
The 400 CFM fan is designed to provide smoke and odor ventilation beneath the cabinetry, and the LED lighting helps illuminate the cooktop without adding separate fixtures. Auto Defrost is another practical daily feature, reducing the need to manually estimate how long frozen food needs to thaw. Together, these functions make the unit more than a simple microwave cabinet.
White styling gives the appliance a clean look that can blend into light cabinetry, though those who prefer dark or stainless kitchens may prefer a different finish. The 1000-watt rating and 1.2-cu.-ft. capacity should suit most standard dishes. Installation is the main limitation: this is an over-the-range model, so adequate overhead clearance, ducting, and proper electrical support are essential.
- Microwave, ventilation, and lighting combined
- Low-profile design reduces visual obstruction
- 400 CFM fan handles everyday cooking odors
- LED task lighting improves visibility
- Auto Defrost adds cooking convenience
- Requires a suitable overhead cabinet or wall
- White finish may not suit every kitchen

9. Sharp SMD2420MS 1.2 Cu.Ft. Sensor Drawer Microwave
The standout feature is Sensor Cook Technology, which makes the Sharp SMD2420MS 1.2 Cu.Ft. Sensor Drawer Microwave more adaptable to foods of different sizes and densities. Combined with under-counter drawer access, it aims to simplify both installation and daily use, especially in a kitchen where a swing door would be inconvenient or difficult to reach.
Rather than depending entirely on a manual time setting, the sensor can evaluate the cooking process and adjust as needed. That is particularly useful for frozen entrees, vegetables, reheated plates, and portions whose exact cooking time is difficult to predict. The 1.2-cu.-ft. interior still provides enough space for common dinnerware without taking up a full work surface.
The drawer design also makes loading mugs, bowls, and taller dishes more natural than squeezing them through a side-hinged door. A touch-control panel gives the front a clean, contemporary appearance and keeps controls organized when the unit is installed. Homeowners should nevertheless measure the cabinet cavity, account for ventilation, and confirm electrical requirements before committing to this under-counter configuration.
- Sensor cooking adjusts for changing conditions
- Front-access drawer simplifies loading
- Spacious 1.2-cu.-ft. interior
- Touch controls provide a clean appearance
- Installed design preserves counter space
- Sensor results can vary by food
- Built-in installation requires careful planning

10. GE 0.9 Cu.Ft. Black Countertop Microwave Oven
Unlike many compact microwaves that make a tight kitchen feel even tighter, the GE 0.9 Cu.Ft. Black Countertop Microwave Oven offers a restrained footprint without giving up the 900 watts needed for common reheating and cooking tasks. It is a sensible alternative to oversized units when a useful but space-conscious appliance is the priority.
The 0.9-cu.-ft. capacity is large enough for typical dinner plates, shallow bowls, and everyday leftovers, making it more versatile than a very small personal microwave. Its black finish provides a neutral appearance that can coordinate with dark appliances and modern cabinet hardware, while the standard countertop format keeps placement flexible.
This model is especially useful in apartments, offices, guest suites, and kitchens where an over-the-range or built-in installation is impractical. It can be moved when counter space changes, which is not an option with fixed built-in appliances. Shoppers should still measure the available depth and height, maintain ventilation space, and confirm that a 900-watt level fits their usual menu.
- Compact 0.9-cu.-ft. capacity
- Useful 900-watt cooking power
- Black finish coordinates with modern appliances
- Portable countertop placement
- Good for common plates and leftovers
- Smaller than full-size models
- Counter ventilation clearance is required

Buyer Guide for Undercabinet Microwave
1. What Is a undercabinet microwave?
An undercabinet microwave is a compact cooking appliance designed to fit beneath wall-mounted cabinets, freeing up valuable counter space while keeping the unit conveniently accessible. These microwaves are typically smaller than traditional over-the-range or countertop models, making them ideal for apartments, galley kitchens, dorm rooms, and RVs. They’re most useful for reheating leftovers, defrosting ingredients, and preparing quick meals, and they appeal to anyone who values tidy surfaces and efficient workflows. Buyers who live in tight spaces or who prefer a minimalist aesthetic often find this style of microwave to be a practical compromise between functionality and form.
2. Key Features That Actually Matter
Not every specification on a microwave matters once it’s installed under your cabinet, so focusing on the right features can save you time and money. Here’s what to prioritize when shopping.
- Performance in everyday scenarios: Look for consistent heating, even defrosting, and a turntable or inverter technology that handles common tasks like reheating leftovers and popping popcorn without hotspots.
- Build quality/durability: A sturdy exterior, secure door latch, and reliable keypad indicate a unit built to handle regular daily use without frequent breakdowns.
- Ease of setup and maintenance: Simple installation instructions, accessible filters, and dishwasher-safe components make daily use and long-term care more manageable.
- Size/capacity/fit: Measure your available space carefully and choose a capacity that matches your household’s typical portion sizes to avoid wasting cabinet real estate.
- Value at different budgets: Higher price doesn’t always mean better performance; set a realistic budget and compare features to ensure you’re paying for what you’ll actually use.
- Brand reliability/warranty: Established brands often offer longer warranties and better customer support, which can be worth the extra cost if repairs become necessary.
- Compatibility with existing setups: Confirm that ventilation, electrical outlets, and cabinet cutouts align with your kitchen’s layout before committing to a purchase.
3. How to Choose the Right undercabinet microwave
Start by evaluating how often you cook and what tasks you rely on most, then match that usage pattern to your budget and available space. Frequent cooks may benefit from higher wattage and advanced sensor settings, while occasional users can often get by with simpler, lower-cost options. Consider your household size and typical portion loads, since a cramped interior can slow down meal prep even when the microwave itself performs well. Finally, read through the top 10 list with your priorities in mind, and don’t feel pressured to choose the most expensive option just because it has more bells and whistles.
4. Common Buyer Mistakes to Avoid
Measuring incorrectly is a frequent error that leads to a microwave that won’t fit under existing cabinets; always double-check width, depth, and height before purchasing. Ignoring ventilation requirements can result in poor airflow and lingering odors, so verify that your setup supports the unit’s ventilation needs. Overlooking wattage and capacity often causes longer cook times and uneven heating, leaving users frustrated with results that don’t match expectations. Skipping warranty and support research means you may be on your own if something breaks, so check return policies and customer service reputation before buying. Finally, assuming all features are essential can lead to overspending on functions you rarely use, so focus on the capabilities that genuinely matter to your daily routine.

Common Questions About Undercabinet Microwave
Can I install an undercabinet microwave myself?
Most undercabinet microwaves are designed for relatively straightforward installation, but it helps to have basic tools and a clear understanding of your cabinet’s dimensions. Follow the manufacturer’s guidelines carefully, and consider enlisting a second pair of hands to hold the unit steady while you secure it in place.
Do undercabinet microwaves vent outside?
Ventilation depends on the model and your kitchen’s existing setup. Some units recirculate air through filters, while others can be connected to external ducting if your cabinets and layout allow it. Check your installation requirements before purchasing.
What capacity do I need for daily use?
For most households, a capacity between one and one and a half cubic feet covers reheating leftovers, defrosting ingredients, and preparing single or small-batch meals. Larger families may prefer a roomier interior to accommodate bigger dishes and platters.
Are undercabinet microwaves as powerful as full-size models?
Many compact units deliver comparable wattage to standard microwaves, though some budget options may run on lower power settings. Higher wattage generally means faster, more even heating, so prioritize power if speed matters in your kitchen.
How often should I replace the air filter?
If your microwave uses a recirculating ventilation system, replacing the filter every three to six months keeps airflow strong and prevents odors from lingering. Always follow the manufacturer’s recommended replacement schedule for best results.
Will an undercabinet microwave fit my existing cabinets?
Fit depends entirely on your cabinet’s dimensions, so measure the width, depth, and height before buying. Many units come with adjustable mounting hardware, but significant discrepancies may require modifications to the cabinet itself.
Do these microwaves come with a warranty?
Most reputable brands include at least a one-year limited warranty, and some extend coverage on parts and labor. Reviewing the warranty terms before purchase can give you added peace of mind and protection against unexpected repair costs.
Final Verdict
Selecting the right undercabinet microwave comes down to balancing your cooking habits, available space, and budget. By focusing on real-world performance, build quality, and proper fit, you can find a unit that streamlines your kitchen workflow without compromising on reliability. Take the time to measure your space, compare the essential features, and read through user feedback to ensure your investment will serve you well for years to come.
