Commercial Microwave Buying Guide: Power, Flatbed vs Turntable and Grill Models
Quick answerA commercial microwave differs from a domestic one in build and controls: stronger door hinges and cavity, programmable buttons so every portion gets the same time, and a design that handles repeated use through service. For reheating portions in a café or takeaway, a programmable 1000W flatbed model is the workhorse. If you also want to brown and crisp, a combination microwave with grill adds a finish a plain microwave can't.
The microwave is the most-used appliance in many small kitchens, and a domestic one rarely survives a year of commercial use. Here's what to look for, and which type suits your menu.
Commercial vs domestic microwaves
A domestic microwave is designed for a few short uses a day. In a café it may run dozens of cycles an hour, with the door opened and slammed each time. Commercial models are built for that duty: tougher doors and hinges, stronger cavities and simple, repeatable controls. Many manufacturers also exclude commercial use from domestic warranties, so a cheap home microwave can be a false economy.
The specs that matter
- Output power (watts). Higher power heats faster. 1000W is the common commercial baseline; higher outputs suit busier kitchens.
- Flatbed vs turntable. A flatbed has no rotating plate to break, chip or misalign, takes square containers, and is quicker to wipe clean.
- Programmable buttons. Save your most-used times once, and anyone on shift gets the same result from one button press.
- Capacity. 25 litres takes a dinner plate or standard container; 38 litres takes larger plates and dishes.
- Grill or combination functions. A grill adds browning and crisping to toppings, gratins and pastries.

Getting consistent results
- Standardise portions and containers. The same weight in the same container heats the same way. Then programme the button.
- Stir or rest. Microwaves heat unevenly. Stir halfway, or allow a short standing time, then probe the thickest part.
- Reheat until piping hot. Food must be thoroughly reheated before serving or hot holding. Check with a probe thermometer and follow your food safety management system.
- Keep the cavity clean. Food splashes absorb energy, slow heating and can damage the cavity over time. Wipe down daily.
- Never run it empty. Running without food can damage the magnetron.
Frequently asked questions
Can I use a domestic microwave in a commercial kitchen?
You can, but domestic models aren't designed for constant use and many warranties exclude commercial use. A commercial microwave is built for repeated cycles and gives programmable, repeatable results.
What wattage microwave do I need for a café?
1000W is a solid baseline for reheating portions. Busier kitchens or larger portions benefit from higher outputs.
What is a flatbed microwave?
A microwave with no turntable. Energy is distributed from below the floor of the cavity, so square containers fit and there is no glass plate to break or clean.
Is a microwave with grill worth it?
If you serve anything that should be browned or crisp, such as melts, gratins and pastries, yes. A plain microwave leaves them pale and soft.
Can I use metal containers in a commercial microwave?
Not unless the manufacturer specifically allows it. Use microwave-safe containers and follow the manual.
