Microwaves mounted below a cabinet offer a clean, space-saving solution that frees up valuable countertop real estate. The core challenge is picking a unit that fits your specific kitchen depth, delivers even heating, and offers the right door or drawer mechanism for your workflow.
I’m Min — the co-founder and writer behind Gadgets Feed. My approach focuses on analyzing real-world installation fit, cavity dimensions, and power consistency across hundreds of customer reviews to separate the genuinely well-designed models from the frustrating ones.
Whether you need a budget-friendly replacement or a premium built-in drawer, this guide to the best below cabinet microwave will help you find the perfect fit for your kitchen.
How To Choose The Best Below Cabinet Microwave
Picking the right microwave for below-cabinet placement requires more than just checking wattage. You need to consider the mounting method, available depth, and whether a drawer or a traditional door works with your kitchen layout.
Measure Your Cabinet Opening and Depth First
The single biggest mistake buyers make is assuming a standard 24-inch-wide cabinet fits any microwave. Countertop models with optional hanging kits typically need a specific rear and side clearance (often 1 inch rear, 3 inches sides) to vent properly. Drawer microwaves, however, are built to slide into a precise cutout, so you must measure the exact width, height, and depth of your cabinet space before purchasing. A 30-inch drawer unit will not fit a 24-inch opening.
Decide Between a Countertop Hanging Kit and a Built-In Drawer
If you already have a standard countertop microwave and want an affordable upgrade, look for models that explicitly ship with or offer an optional hanging trim kit. These units are typically inexpensive but may lack the seamless look of a purpose-built drawer. Dedicated below-cabinet drawers, from brands like Sharp or Midea, offer a flush installation, easier access from a seated or lower position, and often include sensor cooking and child-lock features. Drawer models cost significantly more but provide a premium integrated appearance.
Wattage and Capacity: Match Them to Your Cooking Habits
Compact 700W models under 0.8 cubic feet work fine for reheating coffee, melting butter, or small portions. They struggle with dense items like frozen casseroles or large plates. For a family kitchen, a 1.0 cubic foot or larger cavity with 900W to 1000W ensures faster, more even cooking. Drawer microwaves typically start at 950W for 1.2 cubic foot cavities, which is the sweet spot for most households.

In‑Depth Reviews
1. Sharp SMD2479JS Smart Microwave Drawer
Sharp’s 24-inch drawer microwave delivers the strongest feature set for a below-cabinet install. The 950W output in a 1.2 cubic foot cavity is efficient for most reheat tasks, and the Easy Wave Open gesture control means you can open the drawer without touching it — a genuine convenience when your hands are full. The concealed glass touch panel sits at a 45-degree viewing angle, making it easy to read even when mounted lower in a cabinet.
Smart home integration with Alexa allows over 35 voice commands, and the Sharp Kitchen app provides recipe-guided cooking that automatically adjusts power. The sensor cooking mode handles popcorn and frozen entrees reliably without guesswork. Installation supports both proud and flush mount without extra trim kits, though the unit must fit a standard 24-inch opening.
Reviews highlight the quiet operation and the automatic drawer closing as standout features. A few users reported Wi-Fi connectivity issues, and one noted a burning smell, but Sharp service replaced the unit under warranty. This is the most feature-rich drawer microwave available today.
Why it’s great
- Touchless Easy Wave Open and close
- Alexa voice control with 35+ commands
- Sensor cooking delivers consistent results
Good to know
- Wi-Fi setup may require service visit for some
- Does not support auto-close via Alexa
2. Zephyr 30-inch Built In Drawer Microwave
The Zephyr drawer microwave offers a 1000W power output in a 1.2 cubic foot cavity designed for 30-inch wide cabinet openings. The LCD touch controls provide sensor cook and sensor reheat options that adjust time and power based on humidity levels. This model is built for either standard or flush-mount installation, creating a seamless front with your cabinetry.
Touch open/close operation glides the drawer smoothly, and the 10 power levels give you granular control for delicate tasks like melting chocolate or softening butter. The expanded interior can accommodate a 9×13 baking dish, which is rare for a drawer-style unit. The easy-clean stainless steel coating on the interior makes wiping down spills quick.
User feedback confirms it fits perfectly as a replacement for older 30-inch Sharp drawer models. A few owners note the fan is audible during operation, but the sensor cooking accuracy and flush appearance outweigh the noise for most. The mute function helps minimize sound.
Why it’s great
- Flush mount design integrates cleanly with cabinets
- Sensor cooking adjusts automatically for even results
- Expanded 1.2 cu ft fits a 9×13 baking dish
Good to know
- Fan noise is noticeable during long cycles
- Requires a 30-inch cabinet opening
3. Samsung 1.9 cu ft Countertop Microwave MS19DG8500SRAA
Samsung’s largest countertop microwave offers a 1.9 cubic foot cavity with a scratch-resistant ceramic enamel interior that is easier to clean than traditional paint. Sensor cooking automatically adjusts time and power for items like soup or frozen dinners, while the preset menu covers popcorn, pizza, and beverages. The optional trim kit (sold separately) allows for a built-in look when installed in a cabinet cutout.
At 23.63 inches wide and 18.44 inches deep, this is a substantial unit suited for larger kitchens where counter space permits under-cabinet placement with the trim kit. The 1000W power level (estimated from cavity size) handles dense casseroles and large plates evenly. The door auto-lock feature is designed for safety but can be disabled through the settings menu.
Reviews praise the large interior and ceramic lining for resisting stains. Some owners reported a frustrating auto-lock mechanism that requires disabling, and the first unit shipped damaged for a few buyers. Once set up, however, the heating consistency and sensor accuracy stand out in this capacity class.
Why it’s great
- 1.9 cu ft capacity fits large platters and casseroles
- Ceramic interior resists scratches and stains
- Sensor cooking delivers even results on frozen meals
Good to know
- Door auto-lock can be annoying and needs manual disable
- Trim kit is sold separately for built-in look
4. Midea MM12S2ASZ 1.2 cu ft Drawer Microwave
Midea’s entry into the drawer microwave space offers a 1000W power output in a 1.2 cubic foot cavity designed for 24-inch cabinet openings. The Touch & Go one-touch start control panel simplifies operation, and the auto-menus handle defrost, melt, soften, and reheat tasks automatically. The child-lock function disables the control panel, providing peace of mind in family kitchens.
This drawer-style unit is larger than it appears externally: it measures 25.2 inches deep, so you need a cabinet depth of at least 24 inches. The stainless steel interior and easy-clean design make maintenance straightforward. The 11 power levels allow you to dial in settings for precise cooking needs, from delicate defrosting on low to rapid reheating on high.
Customer reports note quick heating and smooth drawer operation. A few users reported button labels peeling after a few months, and the touch buttons can be hard to see in low light. Despite these cosmetic concerns, the Midea drawer offers the most affordable path to a built-in drawer experience for standard 24-inch openings.
Why it’s great
- 1000W provides fast, even cooking for its class
- One-touch start simplifies daily use
- Child lock adds safety for households
Good to know
- Button labels may peel within a few months
- Requires 25.2 inches cabinet depth
5. GE Spacemaker Countertop JVM6175
The GE Spacemaker is a compact 0.7 cubic foot microwave that ships with the option to install a hanging kit (sold separately) for under-cabinet mounting. At 700W, it runs at a lower power level than full-size units, which means longer cook times for dense items but still effective for typical reheating tasks. The removable glass turntable rotates for even heating and is easy to clean.
Controls include Instant On express cooking buttons, a kitchen timer, child lock, and cooking complete alarms. The auto and manual defrost options give flexibility for thawing meat or vegetables. The stainless steel and black glass design fits well in smaller kitchens, dorms, or RVs. Clearance requirements are minimal — 1 inch at the rear and 3 inches on each side.
Long-term reviews are mixed: some units last years without issues, while a few reports of arcing and failure after 18 months suggest this is best suited for light-to-moderate use. The beeping can be silenced completely, a feature many users appreciate. For the price, it remains the most common entry-level choice for under-cabinet mounting.
Why it’s great
- Small footprint fits tight under-cabinet spaces
- Beep can be fully silenced
- Compatible with an optional hanging kit
Good to know
- 700W requires longer cook times
- Some units report durability issues after 18 months
6. GE Countertop 0.7 cu ft Microwave
This GE countertop model shares the same compact 0.7 cubic foot, 700W profile as the Spacemaker but adds a two-step child lock as a standard safety feature. The glass turntable rotates for even cooking, and the six auto cooking settings include beverage, defrost, pizza, popcorn, and reheat presets. The optional hanging kit (sold separately) enables under-cabinet installation.
The keypad interface includes Instant On express cooking and a kitchen timer. Defrost can be handled automatically by time or manually by setting power levels. This model is ideal for small apartments, dorms, or as a secondary microwave in a home office. The stainless steel and black glass exterior matches the Spacemaker design closely.
Reviews highlight its reliability for light use, with several users reporting it works perfectly after a year. However, a few units failed within a month, suggesting quality control inconsistency. The white version is available if you prefer a different finish. This is a solid backup plan if the Spacemaker is out of stock.
Why it’s great
- Two-step child lock adds safety for families
- Compact 0.7 cu ft fits tight spaces
- Six auto cooking presets simplify daily use
Good to know
- Some units reported early failure after a month
- Hanging kit is sold separately
7. RecPro RV Microwave 1.0 cu ft with Trim Kit
The RecPro 1.0 cubic foot microwave is designed as a direct replacement for Greystone and High Pointe RV units, but it also works well as a built-in microwave for standard 24-inch kitchen cabinets. It includes a picture frame trim kit for a finished look, eliminating the need for an extra purchase. The 900W power output is mid-range, offering faster cooking than 700W models without drawing the full 1500W of larger units.
The touch pad controls offer eight express cook options: popcorn, potato, pizza, beverage, soup, dinner plate, fresh vegetable, and frozen vegetable. The 30-second instant start button is present on the control panel. A child safety lock protects against unintended use, and the defrost function works by weight or time. The stainless steel exterior matches most kitchen appliances.
Reviews confirm it is an easy 10-minute replacement for RV owners, and many home users install it in 24-inch cutouts. A few customers note the lack of a dedicated 30-second button on some batches, and the plastic trim feels slightly less premium than the original. Overall, it is a reliable drop-in option for tight spaces.
Why it’s great
- Includes trim kit for a built-in appearance
- Direct replacement for Greystone/High Pointe RV units
- Eight express cook options cover common foods
Good to know
- Some batches may not include a 30-second button
- Plastic face feels less premium than stainless drawers
8. RecPro RV Convection Microwave 1.1 cu ft
This RecPro model adds convection and grill functions to a standard microwave, offering true baking and browning capability in a compact 1.1 cubic foot package. The 1500W energy consumption (microwave output is lower) powers nine express cook options including roast chicken and cake presets. The touch pad controls and 4-digit LED display are clear and easy to navigate.
The included trim kit measures 24 inches wide by 16.75 inches tall, making it a direct fit for RV and standard 24-inch cabinet cutouts. The child lock and auto-cook menus add convenience, and the stainless steel interior is more durable than painted cavities. Installation is straightforward for existing High Pointe or Greystone owners — it slides in and screws into place.
User reports are divided: some praise the easy replacement and decent microwave performance, while others find the convection function underpowered for baking tasks like browning bread. The microwave alone works well for standard reheating. Expect longer convection cycles than a full-size oven, and ensure proper packaging from the seller to avoid damage.
Why it’s great
- Convection function enables baking and roasting
- Direct replacement with included trim kit
- Nine presets cover roast chicken and cake
Good to know
- Convection mode is slower and less powerful than intended
- Packaging may result in minor damage during shipping
9. Haven Coll 30-inch Drawer Microwave
The Haven Coll (by COSMO) 30-inch drawer microwave offers premium features at a lower entry point than the Sharp or Zephyr. The 1000W output in a 1.2 cubic foot cavity is matched by 10 power levels for precise cooking control. The four automatic cooking options cover melt, soften, popcorn, and beverage — standard presets that handle the most common tasks.
Smart defrosting includes both weight and timed options, and a defrosting rack is included for drip-free thawing. The exterior dimensions of 29.9 inches wide by 23.2 inches deep by 16 inches high fit standard 30-inch cabinet openings. The touch control panel is clean and responsive, though the sensor cook presets require referencing the manual to understand which number corresponds to which food.
Reviews praise the quiet operation and easy cleaning, with several users noting the handleless design fits contemporary kitchens. The control labels are a bit obscure — you will need the sticker or manual to navigate sensor modes. For the price, it offers the same 1000W power and 1.2 cu ft capacity as the Sharp but without smart features or gesture control.
Why it’s great
- 30-inch wide design fits large cabinet openings
- Quiet operation with a mute option
- Defrosting rack included for convenient thawing
Good to know
- Sensor cook presets are not labeled clearly on the panel
- No smart home or app connectivity
