Sharp Carousel SMC1585BS Convection

4.4

$549

Sharp's SMC1585BS is the largest-cavity convection microwave in this guide at 1.5 cu ft and the only model designed from the start to live equally well on a countertop or recessed into cabinetry via the matching trim kit. The 14.1-inch ceramic turntable, 900W microwave, and dedicated Auto Bake, Auto Roast, and Auto Broil presets make it a serious second-oven choice for baking households. The door latch and fingerprints are the friction points.

Strengths

— Built-in capable with optional Sharp RK94S30F (30-inch) or RK94S27F (27-inch) trim kits — the same unit serves countertop and built-in roles
— 1.5 cu ft cavity is the largest in this guide and accommodates a 9-by-13 baking pan with clearance
— 14.1-inch ceramic Carousel turntable spins large casseroles evenly without rim-on-cavity binding

Watch-outs

— Door latch design draws repeated owner complaints — Home Depot reviews flag that the latch button must be pressed firmly before the door will release
— MSRP $779.99 puts the unit in premium-microwave territory when not on sale
— Indicators of trim-kit installation difficulty appear in owner reviews — the 30-inch kit requires a precise cabinet cutout

Ranked #5 in Best Convection Microwaves

Toshiba EC042A5C-BS 1.5 cu ft Convection

4.3

$329

Toshiba's EC042A5C-BS delivers the 1.5 cu ft convection cavity and 1000W microwave at roughly half the price of the Sharp SMC1585BS, with a wider 170-425 degrees Fahrenheit convection range that supports yeast-dough proofing. Consumer Reports rated it 'very good' on heating and 'excellent' on defrost, and the Smart Sensor handles common reheat tasks without manual entry. Skip it only if you need dedicated air-fry — convection alone handles browning competently.

Strengths

— 1.5 cu ft cavity at half the price of competing 1.5 cu ft convection units — best capacity-per-dollar in the category
— Convection range from 170 to 425 degrees Fahrenheit covers proofing through full roasts
— 1000W microwave is competitive with mid-tier dedicated countertop microwaves

Watch-outs

— No dedicated air-fry mode — convection element handles browning but lacks the high-velocity airflow of dedicated air fryers
— Cooling fan runs after convection cycles, adding to ambient kitchen noise
— Stainless interior reflects light into the cavity in a way that makes visual monitoring of dark foods harder

Toshiba EC042A5C-BS 1.5 cu ft Convection

The EC042A5C-BS matches the Sharp SMC1585BS on cavity volume (1.5 cu ft) at roughly $220 less, and it pushes 100W more microwave power. It cannot match the Sharp's built-in trim-kit installability or the Panasonic NN-CD87KS's mode depth, but it covers the convection-and-microwave-in-one-box use case at the lowest price in this guide.
