The list in brief
Which pick fits you?

- For drawer installation: A drawer mounts below the counter or in an island and slides out for access. The Sharp drawer gives you a 30 inch width with a 1.2 cu ft cavity. See pick 7
- For built-in cabinetry: If you are fitting a 30 inch built-in opening, the ZLINE convection model adds speed and sensor cooking in the same trim width. See pick 9

Why these made the list
The pool contains 34 30-inch microwaves from the catalogue after 64 priced listings were folded for near-duplicates. Only new models from established makers were kept, then grouped by mounting style: over-the-range, drawer, and built-in. Each pick was compared on stated width, cooking wattage, interior capacity, vent airflow, and features such as sensor cooking, convection, and smart controls. Missing seller data is marked as not stated. Prices are read live from each listing at the time of writing, and the page refreshes them automatically. No unit was tested for this guide, so all comparisons rest on published specifications and maker information.
Things to weigh before buying
Over-the-range, drawer, or built-in
The first decision is the mounting style. Over-the-range microwaves sit above the cooktop and usually include a vent fan, which is the most common 30 inch type. Drawer microwaves slide out from under the counter or an island, which can be easier to reach and keeps counter space clear. Built-in microwaves fit into a dedicated cabinet opening and often come with a trim kit. Measure your opening and check whether you need venting to decide which style will work.
Cooking wattage
Microwave wattage typically ranges from around 700W to 1500W in the models listed here. Higher wattage usually means faster reheating and cooking, but the actual speed depends on the food and the cavity size. If the seller lists a wattage, use it as a rough comparison. Some 30 inch models, especially drawer and built-in units, do not state wattage in the catalogue, so check the maker's specification sheet before ordering if that number is important to you.
Interior capacity
Capacity in these 30 inch models runs from about 1.0 cu ft to 2.1 cu ft. Over-the-range models often have 1.5 to 1.9 cu ft interiors, while drawer and built-in models frequently stay around 1.2 to 1.7 cu ft. A larger cavity helps with casserole dishes, large plates, and taller containers. If the listing does not state capacity, look for a dimensional drawing or the maker's manual to confirm that your dishes will fit.
Convection, sensor, and smart features
Convection models add a heating element and fan to circulate hot air, so they can brown and bake more like a small oven. Sensor cooking uses a humidity or temperature sensor to adjust time automatically, which can make reheating more consistent. Smart models connect to your phone or voice assistant, letting you start, stop, or monitor cooking remotely. These features are useful, but they add complexity; a basic model may be all you need.
Ventilation and trim kits
Over-the-range models usually include a vent fan with a stated airflow number in CFM. A higher CFM can move more smoke and steam, but actual performance depends on ducting and installation. Drawer and built-in models typically do not include vent fans, so plan for a separate range hood if you need ventilation. For built-in models, check whether the appliance ships with a trim kit or whether the trim is sold separately, because that affects how flush the unit will sit in the cabinet.
Questions
What is a 30 inch microwave?
A 30 inch microwave is an appliance designed to fit a 30 inch wide opening. The width is the outer dimension of the unit or trim, depending on the style. This size is common for over-the-range and built-in microwaves because many standard kitchen cabinets and range hoods are 30 inches wide. Drawer microwaves also use 30 inch widths to match the same cabinet footprint.
Can I use a 30 inch over-the-range microwave without outside ducting?
Many over-the-range microwaves can be installed in either vented or recirculating mode. Vented mode sends air outside through ductwork, while recirculating mode passes the air through a charcoal filter back into the kitchen. Your specific model may include a recirculating kit or require one as an accessory. Check the installation instructions or the maker's manual for the exact requirements for your setup.
Do drawer microwaves require special wiring?
Most drawer microwaves operate on a standard 120V household circuit, but you should confirm before installation. Some built-in models, such as a 240V speed-cook unit, need a dedicated 240V line. Always review the maker's installation specifications to ensure your electrical service matches. If you are replacing an older model, check the existing outlet location as well because drawers often plug in at the back of the cabinet.
How should I clean a 30 inch microwave?
Wipe the interior with a soft cloth, warm water, and a mild detergent after each use. Avoid abrasive pads that can scratch the finish. For splatters, heat a bowl of water for a few minutes so the steam loosens food, then wipe it clean. The FDA also advises covering food, stirring, and rotating during cooking to promote even heating and to help reduce the risk of cold spots.
Is a convection microwave worth it?
A convection microwave can bake, roast, and crisp in addition to heating food quickly. It is useful if you want one appliance that handles both microwave reheating and some oven tasks, especially in a kitchen without a full range. The trade-off is usually more controls and a higher price. If you mostly heat leftovers and cook with a separate oven, a standard model is likely enough.
