People use "hob" and "cooktop" interchangeably, but they fit your kitchen very differently. The real question is whether you want it set into the counter or sitting on top of it.
A gas cooktop sits on your counter and needs no cutting — easy to place, easy to replace, good for rentals. A built-in hob is set into the granite for a flush, seamless, premium look, but needs a counter cut-out planned before the stone is cut.
Both come in 2, 3 and 4-burner layouts with brass burners (even heat, long life). Toughened glass tops wipe clean and look premium; stainless steel is more rugged. Look for auto-ignition and a flame-failure device that cuts the gas if the flame goes out.
Building or renovating a modular kitchen? A built-in hob gives the cleanest finish. Replacing a stove or fitting a rental? A cooktop is simpler and cheaper. See both running side by side at our stores — bring your counter measurements and we'll confirm the fit.
A cooktop sits on top of the counter (no cutting); a built-in hob is set into the granite for a flush look. Same cooking, different fit and finish.
If you're building a modular kitchen and want a seamless premium finish, yes. For a straight stove replacement, a cooktop is simpler and more economical.
Forged brass burners handle Indian high-flame cooking better and last longer than alloy — worth choosing on either a hob or a cooktop.
