Hidden beneath the streets of Brussels, Atsukan invites you into a parallel world where ritual, material, and atmosphere merge into one continuous gesture. Conceived as a modern sentō, a Japanese bathhouse reimagined through a Brussels lens, the space was built to slow the body and awaken the senses. Every element was designed and crafted to evoke intimacy, silence, and flow. Wood, copper, paper, and stone form the language of the space. Ten handcrafted wooden bathtubs align like quiet sculptures, each wrapped in thick patchwork curtains sewn from recycled denim. Lanterns cast a warm light across the room, filtered through hand-painted washi paper. The scent of hinoki, wax, and cedar lingers in the air, carried by the texture of the materials themselves. For Studio Lionel Jadot, Atsukan was not about luxury but about presence. A place where design becomes a ritual, where craft reconnects with the body, and where imperfection finds beauty through use. Every surface tells the story of touch, human, material, and time. Here, the architecture does not impose itself. It breathes, invites, and disappears into the rhythm of the experience.
