AK Series steam generators from Amerec Steam and Sauna are designed for home use, transforming a shower or bathing room into a sauna. The generator uses full power to quickly heat up the steam room to its preset temperature, then cuts power by a third or two-thirds of its heating elements. The result is a more consistent flow of soft steam and more stable temperature — ideal conditions for relaxing and recharging. They install in an attic, vanity, or closet and use the home’s current water supply while pulling electricity from the panel. They use only the current shower space, providing the health benefits of steam. 800-331-0349; www.amerec.com.
