What is the recommended turnover rate for spas?

The recommended turnover rate for spas is typically set at 1/2 hour. This shorter turnover time is necessary due to the specific nature of spa usage and the high bather load that can occur in these environments. Spas are often used for relaxation and therapeutic purposes, leading to a more concentrated presence of contaminants such as body oils, lotions, and other materials. Thus, the turnover rate ensures that the water is filtered and sanitized quickly enough to maintain water quality and safety for users.

In contrast, longer turnover times—such as 1 hour or more—would not be efficient for spas, as they may not adequately manage the contaminants introduced in a shorter period of bathing. Maintaining cleaner water in the spa environment enhances user experience and health, which is why the 1/2 hour turnover rate stands as the recommended standard.
