A shampoo sink in a beauty shop has a fixture unit rating of ___________.

The fixture unit rating for a shampoo sink in a beauty shop is commonly set at 2. This rating is based on plumbing codes that determine the hydraulic load of various fixtures, helping to ensure that the plumbing system is adequately designed to handle the anticipated water usage. The rating takes into account factors such as the number of potential simultaneous uses and the flow rate of water needed.

In the context of a beauty shop, a shampoo sink is considered a specialized fixture that requires a specific amount of water flow for effective use, particularly during hair washing processes. This rating allows for proper sizing of water supply lines and drainage systems to accommodate multiple salon activities at peak times. Understanding fixture unit ratings helps in ensuring efficient plumbing design, which is essential for both sanitation and customer satisfaction in beauty establishments.
