They are designed for frequent use and are a permanent part of the facility's infrastructure. In contrast, a hand wash station is a portable or temporary setup that can be used in various locations, such as outdoor events, construction sites, or areas without permanent plumbing. These stations are self-contained units that include a water reservoir, a basin, and often a foot pump or hand pump to dispense water. They may also have built-in soap dispensers and paper towel holders. Hand wash stations are designed for mobility and ease of setup, making them ideal for temporary or remote locations where traditional plumbing is unavailable. In summary, the main differences lie in their permanence, plumbing requirements, and intended use. Hand sinks are permanent fixtures with direct plumbing connections, while hand wash stations are portable, self-contained units suitable for temporary or remote use.

Hands-free hand sinks operate using sensor-based technology to facilitate touchless operation, enhancing hygiene and convenience. These sinks are equipped with infrared sensors or capacitive sensors that detect the presence of hands. When hands are placed within the sensor's range, it triggers the faucet to release water. The infrared sensors emit an invisible light beam, and when hands interrupt this beam, the sensor sends a signal to a solenoid valve. This valve then opens to allow water flow. Capacitive sensors, on the other hand, detect changes in the electrical field caused by the proximity of hands, similarly activating the water flow. The water temperature and flow rate are often pre-set or adjustable via a control panel, ensuring consistent and comfortable use. Some models incorporate thermostatic mixing valves to maintain a stable water temperature, preventing scalding. Power for these systems is typically supplied by batteries or a direct electrical connection. Battery-operated models are advantageous in areas without easy access to electrical outlets, while hardwired models offer continuous power without the need for battery replacement. Additionally, hands-free sinks may include features like automatic soap dispensers and hand dryers, further minimizing contact and enhancing sanitation.
