Bottom line

The 36-inch Thermador SGSX365FS might be a bit on the pricey side, but expert reviews indicate that you get what you pay for. Cooking performance is great in most respects, with high-heat performance approaching that of induction cooktops. The star-shaped burners look great, but whether they actually do a better job of delivering heat more evenly to a pan is open to debate.

Breaking it down


A top-rated gas cooktop. The 36-inch Thermador Masterpiece SGSX365FS is an excellent gas cooktop, earning high ratings and impressing expert reviewers. It's dubbed an Editors' Choice and a Best of the Year by and earns a Recommended label elsewhere. No cooktop -- gas or radiant electric -- can match the speed at which an induction cooktop can bring a pot of water to a boil. However, the SGSX365FS doesn't miss by much, with its center burner (rated at 18,000 Btu) bringing six cups of water to a boil in 4.5 minutes. An ExtraLow feature improves simmering performance, something that's borne out in testing by one reviewer. does express concern that only the two highest-powered burners generate temperatures greater than 400 degrees F. "It's not unusual for gas burner temperatures to fall a little low, but we'd have preferred a little more heat, says Ethan Wolff-Mann.

Features and design

It hits all the hot buttons. The Thermador Masterpiece SGSX365FS cooktop has five burners ranging in power from 9,100 to 18,000 Btu  topped with continuous cast-iron grates -- a useful feature that makes it easier to move pans from one burner to another. The burners feature Thermador's signature star-shaped burners. The company says those improve heat distribution to a pan, but tests by can't confirm that. The control knobs are made of die-cast metal, not the typical plastic, and the control panel is backlit, with a progressive blue light that indicates burner settings. Other special features include single-point ignition (only the burner being lit receives a spark) and automatic re-ignition, in case a burner blows out. The surface is made of stainless steel, which users say is stylish but scratches easily and can be difficult to keep clean.
