The name single handle kitchen faucet refers to the design, which offers one handle to turn the water on, as opposed to a knob, two handles, etc. Many homeowners enjoy these faucets because of their ease of function. If you’re creating a meal that requires warm water, and you’re holding the phone in your other hand, all you have to do is lift up the single handle and move it to the middle, rather than trying to turn two knobs until you find the right temperature. Also, the handle makes turning on water easier for children and those with difficulties gripping and turning knobs.
