The Yoku Collection by Effe embodies a philosophy of wellness rooted in nature, inspired by the Japanese concept of Shinrin-yoku (“forest bathing”), where design and thermal therapy merge to create a sanctuary of calm. Characterized by its essential, minimalist aesthetic, Yoku balances purity with warmth through natural materials such as heat-treated Aspen or walnut, and large glass surfaces that maintain openness while protecting privacy. In the Yoku S version, the heater is discreetly built into the lowest bench, offering an uncluttered, linear structure and reinforcing the sense of harmony. Vertical wooden slats integrated into the front glass panel filter light, provide shelving to the exterior, and create a subtle visual barrier, enhancing intimacy without closing the space. Available in sauna-only, hammam-only, or combined configurations (including full spa versions), Yoku offers a tailored wellness experience where natural elements interact with precise technology to encourage deep relaxation, respiratory release, detoxification, and nervous system reset. Winner of multiple international design awards (ICFF, ADI Design Index, IF Award, NYCxDesign, German Innovation Award, German Design Award, Good Design Award, Grands Prix du Design), the collection aligns perfectly with Lif8’s vision, elevating wellness spaces into architectural experiences that promote longevity, regeneration, and emotional balance through a profound connection with design and nature.
