KLAFS, a German company with nearly a century of experience in sauna manufacturing, has introduced its retractable sauna unit to the U.S. market.
Dubbed the S1, this product expands from a compact storage configuration that resembles a bookshelf to three times its size at the push of a button. This design sensibility allows the retractable sauna unit to function as a full-scale sauna when in use and then collapse to occupy minimal floor space when not needed.
KLAFS constructs this product with insulated walls, an eight-millimeter glass panel, and premium finishes. Exterior options in matte black or walnut are paired with a walnut interior, and the unit is available in three sizes. The S1's roprietary SANARIUM control system offers five distinct climate settings, enabling users to customize temperature up to 210 degrees Fahrenheit, humidity levels, and ambient lighting to suit personal preferences.
