Onsen is a Japan-inspired zen bathhouse fit in a former auto body shop in San Francisco. Designed from scratch by husband and wife Sunny Simmons and Caroline Smith, they aimed to keep the original spirit of the place, while adding a modern touch. They treasured the old, brick walls entwined by hanging plants and focused on minimal, wooden insets to finish the space. It features a communal bathing room, six treatment rooms, dry sauna and head cold showers, while collected bathhouse tickets from around the world were used as an interior decoration. No luxury would be complete without an intimate meal in a chef-driven restaurant serving seasonal cuisine at Onsen’s front.
