A water cooler is a common appliance used to dispense cold and, in some cases, hot drinking water. It typically operates with large water bottles that need to be replaced periodically or is connected directly to a water supply for continuous use. Water coolers are prevalent in offices, homes, and public areas, providing a convenient and readily available source of hydration.

They often come with features like cooling and heating functions, making them suitable for various beverage preferences. Water coolers are eco-friendly, as they reduce the need for single-use plastic bottles and promote responsible water consumption, making them a practical choice for both residential and commercial settings.
