The Sharp R-22GTF brings 1200W of radiant heating and 11 power levels to a 0.7 cu ft stainless steel unit priced at $1,229, a striking premium for the cavity size. The wide 16-inch turntable and precision power control are genuine strengths, but the price makes this a hard sell outside of commercial applications.
Commercial or institutional kitchens where a durable, high-wattage compact unit with fine power-level control is needed and budget is secondary to reliability and throughput.

Anyone equipping a home kitchen or a small office break room, $1,229 for 0.7 cu ft is extremely difficult to justify when consumer microwaves with similar or greater capacity deliver comparable performance at a fraction of the cost.

Overview
The R-22GTF's standout specs are its 1200W output and 11 power levels. Higher wattage means faster heating, and 11 power increments give operators real flexibility for defrosting, reheating at reduced power, or holding food warm without overcooking. This is the kind of control spread typically found on serious commercial equipment.
The 16-inch turntable is unusually large for a 0.7 cu ft interior, it accommodates wide plates and containers that would not fit in similarly compact units. The silver color and radiant heating method indicate a unit built for reliability under sustained use.
The price of $1,229 at 0.7 cu ft is the core issue. The dimensions are 13.19 x 20.4 x 20.07 inches and it weighs a substantial 60 lb, this is a heavy, serious appliance that will stay put once installed. With a 3.5 rating across 5 reviews, buyer feedback is too sparse and mixed to be conclusive, which adds risk to a four-figure purchase.
Pros
1200W output heats quickly for the 0.7 cu ft cavity size
11 power levels allow precise control over heating intensity
16-inch turntable is notably large, fitting wide dishes
Radiant heating method is reliable for standard reheating tasks
Stainless steel finish suited to commercial environments
Cons
At $1,229 for 0.7 cu ft, the price-to-capacity ratio is very poor
Weighs 60 lb, not practical to move once positioned
Only 5 reviews with a 3.5 rating, limited buyer confidence
No smart or connected features at this price point

Performance notes
At 1200W, the R-22GTF heats faster than typical 700-900W consumer models. The radiant heating method and 11 power levels together make it well-suited for precision tasks like staged defrosting or low-power warming. Button controls are straightforward. The 16-inch turntable, combined with the 20.4-inch width, means the unit itself is not especially compact on the counter even though its cavity is only 0.7 cu ft. It operates on 120V, which is standard US wiring.
What buyers say
With a 3.5 rating across just 5 reviews, the feedback pool is too small to draw reliable conclusions. The mixed rating at this price level is worth noting, buyers at this tier have high expectations, and a 3.5 suggests some disappointment among early purchasers.
Radiant heating in a microwave context refers to the use of infrared or quartz elements in addition to or instead of standard magnetron-based microwave energy. It is commonly used in commercial units to brown or crisp food surfaces that standard microwave energy alone would leave soft.
Why does a 0.7 cu ft microwave cost $1,229?
The R-22GTF is priced as a commercial-grade unit built for sustained daily use in a food service context. Commercial microwaves are engineered for heavier duty cycles, higher wattage output, and longer service life than typical consumer models, which drives the price well above consumer alternatives.
Is the 16-inch turntable actually usable in a 0.7 cu ft cavity?
The turntable diameter is 16 inches but the interior cavity is 0.7 cu ft, so the turntable spans the full interior floor. It accommodates wide, flat items like standard dinner plates and some larger containers, which is a genuine practical advantage over smaller turntables in compact microwaves.
