Most people assume a microwave is just a box that makes popcorn, but the built-in variety functions more like a precision kitchen appliance. Choosing the wrong unit can leave you with a massive gap in your cabinetry or a door that refuses to clear your countertops.
Getting the right fit is arguably more difficult than deciding between brands. We have gathered the best rated built in Microwaves to simplify the process for you. Read on to see which models actually belong in your kitchen.
Key Takeaways
- Measure your existing cabinet cutout dimensions three times before purchasing any trim kit or unit.
- Verify whether the model requires a dedicated trim kit as these are often sold separately and can be surprisingly expensive.
- Prioritize units with 1000 watts of power if you want to avoid long, uneven cooking times for dense meals.
- Consider a drop-down door design if you need easier access for sliding heavy dishes into the cavity.
- Confirm your electrical requirements early, especially if you are replacing a unit that plugs into a standard wall outlet.

It is a straightforward workhorse that avoids unnecessary bells and whistles. Just keep in mind that the capacity is modest, so it might not be the best pick for large holiday turkeys or massive casserole dishes.

The Gallery series aesthetic is quite sharp, though you should remember that the trim kit is a separate purchase. You will need to account for that extra step during your installation planning.

GE 30-Inch Over-the-Range Microwave
Sometimes you need to save counter space, and this unit tackles that problem by living right above your stove. It acts as both a powerful exhaust fan and a reliable microwave, which saves you from installing a separate hood.
The 1,000 watts of power is plenty for everyday chores. It is a bit more industrial in its footprint, so make sure your kitchen layout can support a unit that sits permanently over your cooktop.

It features a flat bottom design that makes sliding heavy containers in and out a breeze. The only drawback is the installation complexity, as you will need a specific cabinet space designed to house a sliding drawer mechanism.

- Unit Width:24 inches
- Power Wattage:1000W
- Material Finish:Stainless steel

Designed with the compact lifestyle in mind, this unit is a favorite for those living in RVs or tiny homes. It provides a convection cooking mode, which basically means it functions like a small secondary oven for baking and roasting.
It is quite rugged for its size, but don't expect it to replace a full-sized wall oven. It is best suited for snacks, small bakes, and quick meals on the road.
- Brand Name:RecPro

It offers a massive cavity for large dishes. Just remember that it requires a trim kit, which you will need to buy separately to get that finished look in your kitchen.

Summit 24-Inch Over-the-Range Microwave
If you need an over-the-range unit but have a tight cabinet width, this is a rare find. Most overhead units are 30 inches, but this one trims things down to 24 inches to accommodate smaller kitchens or older homes.
It handles the basics well and keeps your counters clear. Because of its smaller size, the internal capacity is tighter than a standard microwave, so it might struggle with very large dinner plates.
- Brand Name:Summit
- Model Type:Over-the-range
- Capacity Volume:0.9 cubic feet
- Unit Width:24 inches
- Material Finish:Stainless steel
- Additional Feature:Integrated exhaust fan

Frequently Asked Questions
Can I install a countertop microwave in a cabinet?
You should only do this if the manufacturer explicitly states it is safe for built in installation. Most countertop units need specific air gaps on all sides to prevent fires. If you want the built in look, buy a model that supports a factory trim kit. This ensures proper ventilation and keeps your warranty intact.
What is the difference between a built in microwave and an over the range model?
An over the range microwave doubles as a ventilation hood for your cooktop. It is designed to capture smoke and steam from your stove. A true built in microwave is meant to sit flush with your cabinets, often in a wall or an island. They do not have the exhaust fans needed to clear a stovetop.
How much space do I need for a trim kit?
You need to account for the outer dimensions of the trim frame, not just the microwave itself. Check the installation guide for the required minimum overlap on your cabinetry. Double check your surrounding drawers and cabinet doors. You want to make sure the trim does not block them from opening fully.
Do I need a dedicated electrical circuit?
Many high wattage built in microwaves require a dedicated 120V outlet on its own circuit. This prevents the microwave from tripping your breaker when you turn on other appliances. Check your home's electrical panel and the amperage requirements listed on the microwave. If you are unsure, calling a licensed electrician is the safest path forward.
How long should a built in microwave last?
You can expect a quality unit to provide 8 to 10 years of service with regular maintenance. Keeping the interior clean and preventing food splatter buildup helps the internal components last longer. If you hear grinding noises or notice the turntable motor struggling, it may be time for a repair or a replacement. Simple fixes are sometimes possible, but often the cost of parts makes a new unit more economical.
