Juvenex Spa

Juvenex Spa is a Korean-style spa on the fifth floor of an office building on West 32nd Street in Koreatown, open 24 hours a day. Its four-step Jade Journey circuit moves through a Jade Igloo Sauna built from semi-precious stones, a herbal steam sauna, a baked-clay sauna and Japanese-style soaking tubs, and the spa is known for its Korean body scrubs. Daytime hours are women only, with couples admitted in the evening. The whole floor can be rented for groups; treatment programmes start at $135.
