What is the plumbing requirement for each cosmetological establishment?

The plumbing requirement for each cosmetological establishment specifies the necessity for hot and cold running water at all times to ensure the safe and hygienic practice of various beauty services. This requirement is crucial for several reasons.

First, access to hot and cold water allows for proper sanitation and hygiene practices, which are essential in preventing the spread of infections and ensuring client safety. For example, hot water is necessary for sanitizing tools and equipment, while cold water can be important for other applications, such as rinsing and cooling treatments. Additionally, having both hot and cold running water readily available facilitates a wider range of services to be performed, such as hair washing, skin care treatments, and other cosmetological procedures that require temperature-controlled water.

This plumbing standard reflects the health and safety regulations set forth to maintain cleanliness and professionalism within the industry. Other options that suggest only one type of water supply or no requirement at all do not meet the essential health criteria for operating a cosmetological establishment, thus highlighting why the requirement for both hot and cold running water is the correct answer.
