While gas stoves and hobs are both cooktops, they differ from each other in terms of design and functionality. A gas stove is a tradition cooktop that’s freestanding, which means that the appliance needs to be placed on the kitchen platform. On the other hand, a gas hob is a modern cooktop that has a sleek built-in design which means it sits levelled to your kitchen platform. In terms of functionality, a gas stove only comes with basic on and off functions, while gas hobs have a host of features that make cooking simple.
