Sauna manufacturer Klafs from Schwäbisch Hall has developed a fully-automatic expandable sauna for living or guest rooms. In its retracted state, the Saunabox S1 looks like a closet, with a depth of 60 cm. At the push of a button it expands to 160 cm, just like the zoom lens on a camera. The control unit can be operated via WiFi or even on the move with a smartphone.
