Understanding Ideal Hot Tub Temperatures
Hot tubs provide an excellent way to relax and enjoy some hydrotherapy.
However, finding the perfect temperature for your hot tub can be a delicate balance. The recommended temperature range for a hot tub is between 100-102 degrees Fahrenheit, but certain factors such as age, health conditions, and even the season can influence individual preferences.
