Thermal Spring is a hot spring bathing facility on the first basement level of a hotel in Kyoto, Japan. The interior covers 469 square meters, including the entrance and the corridor, and uses natural hot water that rises from the site. The design is inspired by the geology of Kyoto, by the spiritual traditions of the city and by the memory of the land. Garden stones found on the site were reshaped and reused for stone sculpture and flooring. A clay wall in deep indigo recalls the local dyeing culture, while a granite wall with a natural surface suggests underground water veins.
