The ThermadorSGS305TS gas cooktop brings professional‑level performance to a compact kitchen footprint, delivering the power and precision serious home cooks expect in a refined 30‑inch design. With an overall width of 31 inches, this Masterpiece® series cooktop is engineered to offer the cooking flexibility you’d normally associate with a larger 36‑inch model, thanks to its thoughtfully arranged five‑burner layout that maximizes usable cooking space. At the heart of the unit are Star® Burners, a patented five‑point design that sets this cooktop apart from typical round burners by providing more flame ports and broader flame coverage, helping to eliminate cold spots and promote faster, more even pan heating across a wide variety of cookware. The powerful 16,000 BTU center burner gives you an extra boost of heat for rapid boiling, intense searing, and high‑heat stir‑frying, while the surrounding burners offer a range of outputs ideal for everything from gentle simmering to everyday sautéing. Continuous cast‑iron grates span the full cooking surface so you can slide heavy pots and pans smoothly from one burner to another without lifting, making multi‑course meals and large family dinners easier to manage. For everyday convenience, the sealed burner design helps keep spills and splatters on the surface where they’re easy to wipe away, instead of dripping into the burner box, and the electronic re‑ignition system automatically reignites the flame if it goes out, adding peace of mind as well as consistent performance. Finished in sleek stainless steel with robust metal control knobs, the ThermadorSGS305TS blends seamlessly into both contemporary and transitional kitchen styles, offering a premium look that matches its high‑end capabilities. Whether you’re outfitting a new build or upgrading an existing space, this cooktop delivers a compelling combination of distinctive Star® Burner technology, high‑output center power, space‑saving five‑burner configuration, and easy‑clean construction that distinguishes it from many standard 30‑inch gas cooktops on the market.
