The kitchen faucet is generally a multi-function faucet with a high outlet and a long water outlet. The double faucet also has a hose design and a hot water line. There are single-hole straight installations and in-wall installations. If the kitchen has hot water lines, the faucets should also be double-connected. In addition, the water outlet of the kitchen faucet is taller and longer, and some have a hose design for you to wash food.
