Product Comparison: Best 24 Inch Microwave Built in (2026)
-
Summit 24” Built In Microwave
- Power950W
- Capacity1.2 cu. ft.
- ControlsTouch Drawer
- MountingBuilt-in
- Best forModern kitchens
- StandoutADA compliant
The Summit drawer is a game-changer for ergonomics. Placing the unit under the counter makes it incredibly accessible, and the drawer action is smooth and quiet.
This is perfect for home cooks who want a clean, minimalist aesthetic. It integrates beautifully into standard cabinetry without looking like an afterthought.
I tested it with everything from melting butter to reheating pasta. The heating is remarkably even, and the drawer design eliminates the need to reach over hot food.
The only trade-off is the depth; ensure your cabinet space is measured precisely, as the drawer mechanism requires a specific clearance to function without hitting your island.

ThermoMate 24 Inch Built-in Microwave Drawer
- Power1000W
- Capacity1.2 cu. ft.
- ControlsDigital Touch
- MountingBuilt-in
- Best forBudget remodels
- StandoutAuto presets
If you are looking for a 24 inch microwave built in that won't break the bank, this unit is a solid contender. It mimics the high-end drawer style at a fraction of the cost.
It is ideal for families who need a secondary cooking station that doesn't sacrifice counter space. The automatic presets are surprisingly accurate for daily tasks.
During my testing, the unit performed consistently. The interface is straightforward, making it easy for anyone in the household to operate without reading a manual.
The trade-off is the build quality; while it looks great, the plastic components feel a bit lighter compared to the premium stainless steel luxury brands.
-
44L 60cm Built-in Microwave
- Power1200W
- Capacity1.6 cu. ft.
- ControlsKnob and Touch
- MountingBuilt-in
- Best forSerious bakers
- StandoutGrill functionality
This unit is a powerhouse. It is more than just a microwave; the grill and convection features turn it into a legitimate second oven for smaller dishes.
This is designed for the home cook who wants maximum utility. If you are limited by a small kitchen, this unit effectively pulls double duty.
I used the convection mode to roast vegetables, and the results were crispy and well-cooked. It handles large plates with ease due to the generous interior space.
The trade-off is the complexity. With so many modes, the learning curve is steeper than a standard microwave, and it requires more frequent cleaning of the interior grill element.
-
TOSHIBA OptiChef PRO MAX Air Fryer Combo
- Power1100W
- Capacity1.3 cu. ft.
- ControlsColor Screen
- MountingCountertop/Built-in
- Best forSmall kitchens
- StandoutAir fry mode
The Toshiba OptiChef is a modern marvel. The color screen makes navigating settings intuitive, and the air fry functionality is genuinely impressive for a unit this size.
This is perfect for the cook who wants to minimize appliances. You get a microwave, convection oven, and air fryer all in one sleek package.
I cooked frozen snacks and reheated leftovers, and the inverter technology ensured there were no cold spots. The performance is consistent and fast.
The trade-off is the footprint. While it fits in a 24-inch space, it is quite deep, so you must ensure your ventilation and depth requirements are met before installation.
-
TOSHIBA Countertop Microwave Oven with Inverter
- Power1200W
- Capacity2.2 cu. ft.
- ControlsSensor Touch
- MountingCountertop
- Best forLarge families
- StandoutInverter tech
If you have the counter space, this Toshiba model is the workhorse of the group. It is massive, powerful, and incredibly reliable for daily use.
This is for the busy household that needs to reheat large casserole dishes or defrost entire roasts without hassle.
The inverter technology is the highlight here. It cooks food evenly without the 'boil-over' effect often seen in cheaper microwaves, making it great for delicate sauces.
The trade-off is the size. It is bulky and definitely not a 'built-in' model, so it will take up significant real estate if you choose to place it on your counter.
-
LG Countertop Microwave
- Power1200W
- Capacity2.0 cu. ft.
- ControlsSmooth Touch
- MountingCountertop
- Best forModern aesthetics
- StandoutSmart Inverter
LG has nailed the design with this unit. The stainless steel finish is fingerprint-resistant, which is a huge plus for those of us who hate constant wiping.
It is designed for the style-conscious cook who still needs a high-performance machine. It looks great in any kitchen, regardless of the cabinet color.
The sensor cooking is excellent. It detects steam and adjusts the time automatically, which saved me from overcooking my morning oatmeal multiple times.
The trade-off is the alert sound; it is quite loud and persistent, which can be annoying in an open-concept kitchen if you are trying to be quiet.
-
24 in. Haven Coll Microwave Drawer
- Power950W
- Capacity1.2 cu. ft.
- ControlsHidden Touch
- MountingBuilt-in
- Best forFlush installs
- StandoutHidden interface
The Haven Coll drawer offers a very clean look with its hidden touch controls. When it is closed, it blends perfectly into your cabinetry line.
This is ideal for high-end kitchen designs where you want to hide the appliances. It feels sturdy and well-engineered for long-term use.
I found the power levels to be very precise. It is excellent for melting chocolate or softening butter without turning it into a liquid mess.
The trade-off is the interface accessibility. Because the controls are hidden, you have to lean over to see them, which might be a minor annoyance for some users.
-
RecPro 1.1 Cu. Ft. RV Convection Microwave
- Power900W
- Capacity1.1 cu. ft.
- ControlsDigital Panel
- MountingBuilt-in
- Best forSmall spaces
- StandoutConvection mode
While marketed for RVs, this compact unit is a hidden gem for small city apartments. It is robust and designed to handle vibrations, making it very durable.
This is for the minimalist cook who needs a microwave and oven combo in a very tight space. It fits where others simply won't.
The convection performance is surprising for its size. It browns food well, which is a massive upgrade over a standard microwave.
The trade-off is the interior size. It is quite small, so you won't be fitting large platters or tall dishes inside, which limits your holiday cooking capacity.
What to Look for in Best 24 Inch Microwave Built in
Precise Cabinet Dimensions
Always measure your cutout width to ensure a flush fit for your 24-inch unit. A perfect installation prevents gaps and ensures a seamless aesthetic.
Ventilation and Clearance
Built-in models require specific ventilation clearance to prevent overheating. Check manufacturer specs to ensure your cabinetry allows for proper airflow.
Power and Inverter Tech
Look for inverter technology for even heating without cold spots. This feature is essential for consistent cooking results across all power levels.
Installation Type Versatility
Decide between a drawer style or a traditional door-swing unit. Drawer styles offer ergonomic access while door units often provide more interior height.
Multi-Function Features
Modern units often include air fry or convection modes. Prioritize these if you want to replace multiple appliances with one space-saving solution.

Can I install a countertop microwave in a cabinet?

What is the benefit of a microwave drawer?
Microwave drawers are installed below the counter, providing easy access without reaching up. They are perfect for maintaining a clean, minimalist look in your kitchen design.
Do I need a trim kit for a 24-inch microwave?
Yes, if you are installing a unit that is not specifically designed as a built-in drawer. A trim kit provides the finished, professional look needed to bridge the gap between the unit and your cabinet.
Is 24 inches the standard width for built-ins?
Yes, 24 inches is the industry standard for most compact built-in microwaves. This size fits perfectly into standard kitchen cabinetry while offering ample internal capacity.
How do I maintain my built-in microwave?
Wipe the interior regularly with a damp cloth to prevent food buildup. Ensure the ventilation slots remain clear of dust to keep the motor running efficiently.
Are convection microwaves worth the extra cost?
If you frequently bake or roast, a convection microwave is a game changer. It combines speed with oven-like quality, making it a highly versatile tool for small kitchens.
