Our portable indoor infrared saunas using a break-through technology are manufactured to be stylish, reliable, and functional. Each sauna comes with between 3 and 8 ceramic infrared heaters. These saunas are built from hemlock fir / birch. Each sauna comes with a radio, CD player, and reading light, all controlled by a digital control box that can be accessed from inside and outside the saunas. Best of all they are portable and operate on 110V.
