KOHLER, Wis., March 23, 2026 /PRNewswire/ -- KLAFS, the global leader in luxury sauna innovation and German design excellence, announces the U.S. launch of its extraordinary S1, the world's first retractable sauna. The KLAFS S1 is engineered to transform the at-home wellness market, bringing luxury sauna relaxation into everyday living spaces with groundbreaking technology and a sleek architectural presence.

The S1 expands from the size of a bookshelf to three times its size at the touch of a button, delivering a full-scale sauna without sacrificing valuable square footage. Its modern, sophisticated, and space conscious design features insulated walls, premium finishes, and 8mm glass for reliable performance, creating a refined focal point that blends effortlessly into contemporary interiors.

Equipped with KLAFS' proprietary SANARIUM control, the S1 offers five distinct climate experiences empowering customers to personalize heat - up to 210° F, humidity, and ambiance.

"For nearly a century, KLAFS has pushed the boundaries of sauna design, and the S1 represents our most transformative innovation for the wellness industry yet," says Phillip Rock, CEO of KLAFS. "We're thrilled to introduce a luxury wellness experience that makes sauna ownership attainable for people who may not have considered it possible due to limited space in their homes. By combining advanced engineering with thoughtful, space efficient design, we've created a sauna solution that elevates wellness in any home."

Founded in 1928 in Germany, KLAFS has long set the global standard for craftsmanship, engineering excellence, and design driven innovation. Its products and services are trusted by the world's top hotels, wellness resorts, and private residences. The U.S. introduction of the KLAFS S1 extends this legacy, bringing European design heritage and next generation form and functionality to American homeowners seeking a more intentional and accessible approach to wellness.

The S1 is available in three sizes—small, medium, and large—accommodating 2 to 3 users. Exterior finishes include matte black or walnut, both paired with a walnut interior for a warm, contemporary aesthetic.

S1 joins the expanding KLAFS U.S. portfolio of luxury saunas, including ARISO, VALORA, S11, TARAS, and custom solutions. Each reflects the brand's unwavering commitment to innovation, craftsmanship, and personalized wellness experiences designed for the modern home.
