LÖ-LU runs wood-fired, Finnish-style sauna sessions at 1408 S. 4th Street in Columbus, in a sauna originally built from a converted 1987 bread truck. The hot room is heated to roughly 180-200°F and holds up to 10 people. A booking covers two hours of hot-cold rounds with a cold plunge and bucket shower, an on-site sauna guide, lockers and changing space. Bathing suits are required, and private parties are arranged on request.
