What is the maximum allowable temperature for spas?

The maximum allowable temperature for spas is set at 104°F to ensure the safety and health of users. This limit is established because temperatures above this threshold can lead to adverse health effects, including hyperthermia. Extended exposure to higher temperatures can strain the cardiovascular system, especially for individuals with preexisting health conditions, and may increase the risk of overheating, dehydration, or heat-related illnesses. Setting the maximum at 104°F strikes a balance that allows for a comforting and relaxing experience while minimizing health risks associated with higher water temperatures. It's crucial for spa operators and users to adhere to this guideline to promote a safe environment.
