Hi. On average, it takes our model saunas approximately:

*20 minutes to reach into 100 degrees Fahrenheit/38 degrees

Celsius (with a starting temperature above 66 degrees

Fahrenheit/19 degrees Celsius)

*25-30 mins to reach about 115-120 degrees

Fahrenheit/46-49 degrees Celsius (depending on sauna model)

*35-40 minutes to reach about 125-130 degrees

Fahrenheit/52-54 degrees Celsius (depending on sauna model)

*45-50 minutes to reach about 135-140 degrees

Fahrenheit/57-60 degrees Celsius (depending on sauna model)

Please keep in mind that you must preheat the sauna room to the set temperature before entering. Also, the most commonly used temperature setting is between 118 degrees Fahrenheit / 48 degrees Celsius and 122 degrees Fahrenheit / 50 degrees Celsius. The way the sauna room works is when you set the Control Panel to say 120 degrees F / 49 degrees C, the heaters will turn off when that temperature is achieved. And even though the sauna does allow the user to set the Control Panel to 151 degrees F, this is specifically for those users who do not want the heaters to ever turn off as the sauna room will never achieve 151 degrees F / 66 degrees C. Thank you for your inquiry.
