Bring precision, speed, and a sleek built-in look to your kitchen with the ThermadorCIT304BB 30-inch induction cooktop, a refined black-glass surface designed to deliver professional-level control in a streamlined, frameless format. With a generous 31-inch overall width, this cooktop fits beautifully into contemporary countertops while giving you the responsive performance that makes induction cooking such a favorite for serious home chefs. One standout advantage is the ultra-spacious 11-inch heating zone, built to comfortably handle larger cookware and deliver strong, even heat where many comparable 30-inch cooktops feel cramped or underpowered. When time matters, PowerBoost® helps accelerate heating by increasing element power for faster boiling and quicker heat-ups, making weeknight cooking noticeably more efficient without sacrificing control. For tasks that demand intense, short bursts of heat—especially when cooking with oil—PanBoost® provides 30 seconds of maximum power to rapidly bring pans up to temperature, a specialty feature that’s not commonly found on standard induction models. Beyond raw power, the cooktop is engineered for consistency: CookSmart® offers pre-set temperature guidance designed to help maintain optimal heat for different cooking styles, reducing guesswork and helping you achieve more repeatable results. Everyday usability is elevated with 17 precise power levels and an illuminated touch control panel that’s easy to wipe clean, keeping the surface looking as polished as it performs. For a more personalized experience, the Favorite button can be set up to access preferred functions through the Home Connect® app, adding convenient customization and smart control that goes beyond basic on-and-off operation. If you’re upgrading to induction and want a premium 30-inch platform that blends high-end design with distinctive performance features, the ThermadorCIT304BB is built to make cooking faster, cleaner, and more confidently precise.
