S1

The world's first and only expandable sauna: at the press of a button the S1 extends from a retracted depth of just 24 inches to a full 63-inch cabin in about 40 seconds, then collapses to wardrobe depth when you're done — the answer to the apartment problem. SANARIUM climate system runs five distinct heat-and-humidity modes from a dry Finnish sauna to tropical steam, with the VARIUS heater hidden under the bench, app and touchscreen control, Bluetooth speakers, and dimmable backrest lighting. Available in three sizes; winner of the Red Dot, iF, and German Design awards. Arrives Summer 2026.
