The I/S sauna provides the best of both worlds. You like traditional sauna but your spouse prefers infrared sauna? No problem. On weekends you like a traditional sauna taken with others–and with lots of steam–but during the work week you like the mild-soothing infrared sauna heat therapy? No problem. The InfraSauna(TM) by Saunatec(R) is the ultimate sauna–a blending of our Traditional Finnish Saunas with our CarbonFlex(R) Infrared Technology.
