Most pro-style ranges come in standard widths of 30, 36, 48, and 60 inches. Larger widths mean more burners or other cooktop options, such as griddles and grills, and more oven space, too. The ovens in a 36-inch unit can handle catering trays; 48- and 60-inch models can fit two ovens.
How much do they cost?
You can pay anywhere from $3,500 to $20,000 for a pro-style range, depending on the size, features, and model.
What if it breaks?
Expect to get at least 20 years out of your investment, but features like electronic burner ignitions can be extremely costly to replace when they fail, and finding companies to service some lesser-known brands can be difficult.
Gas or electric?
While pro-style burners are always gas, they can be paired with a gas or an electric oven (the latter option is known as "dual fuel"). Electric ovens offer more cooking modes and more even heat but can add as much as $2,000 to the cost. Some cooks prefer gas ovens for their moister heat. Most pro-style gas ovens don't self-clean, and those that do cost at least $1,000 more.
