Most people find a temperature range of 100-102 degrees Fahrenheit to be comfortable for a hot tub. Some like it as hot as 104 degrees Fahrenheit, which is the recommended maximum temperature for a hot tub.
Hot tub maintenance and safety is very important. It could be harmful for a pregnant woman to be in a hot tub; any pregnant woman should check with a doctor first to see if it's okay to be in a hot tub. Any children aged five years or younger should not be in water hotter than 95 degrees Fahrenheit and should only remain in hot water for five to ten minutes. It is important to care for your hot tub water, which should be changed occasionally and treated to maintain the proper pH levels.
