What is the maximum temperature recommended for a spa?

The recommended maximum temperature for a spa is typically 104 degrees Fahrenheit. This limit is set to ensure the safety and comfort of users, as higher temperatures can lead to overheating, dehydration, or even heat-related illnesses. At 104 degrees, the water is hot enough to provide therapeutic benefits and relaxation while remaining within a safe range for the majority of individuals.

Spas that exceed this temperature can pose risks, particularly for vulnerable populations, such as pregnant women, the elderly, and individuals with pre-existing health conditions, who may have a lower tolerance for heat. Additionally, many health guidelines and regulations reflect this standard to promote safe use of spa facilities. This is why 104 degrees Fahrenheit is the recognized maximum temperature for spas in the context of safety and health regulations.
