In which location should drinking fountains or water coolers not be installed?

Drinking fountains or water coolers should not be installed in restrooms primarily due to health and sanitation concerns. Restrooms are environments where hygiene is critical, and the proximity to potential contaminants such as bacteria and viruses makes it unsuitable for drinking water sources. Installing drinking fountains in restrooms could lead to cross-contamination and compromise the safety of the drinking water.

Additionally, from a practical standpoint, people often prefer not to consume water in a space that is associated with human waste and sanitation issues. It is vital to maintain a hygienic environment for drinking water sources to ensure public health and safety.

While other locations such as near food preparation areas or outdoor settings could have specific considerations, restrooms inherently pose the greatest risk and are generally considered inappropriate for the installation of drinking fountains or water coolers.
