A single cold water faucet is a type of faucet that only supplies cold water. It is commonly used in commercial settings, such as restaurants, bars, and outdoor kitchens, as well as in homes for specific needs like garage sinks or laundry rooms. Single cold water faucets are simple in design and relatively easy to install and use.

One of the significant advantages of a single cold water faucet is its affordability. It is cheaper to install and maintain because it doesn't require hot water pipes or an expensive mixing valve. Additionally, it is a great option for outdoor activities where hot water is not crucial, such as washing cars or watering plants.

However, the primary disadvantage of a single cold water faucet is its limitation in functionality. It is not suitable for tasks that require hot water, such as washing dishes or filling up a bathtub. If you need hot water for other chores, it is recommended to install a standard hot and cold mixer faucet.

A single cold water faucet is an excellent choice for specific circumstances, such as outdoor activities or commercial kitchens. Its simplicity and affordability make it a convenient option, but it comes with limitations in functionality.
