Day Spas With Sauna and Steam Rooms in New York

Heat is its own corner of New York's spa trade. The spas on this page have a sauna, a steam room, an infrared sauna, a Russian banya or a Turkish hammam for guests: thermal bathhouses in Manhattan and Brooklyn, Korean-style saunas in Flushing, hotel and resort spas, and day spas that add a steam room to the treatment rooms.

Some sell a day pass to the heat rooms alone, others open them only to guests booking a treatment. Before you go, ask what access includes, whether the space is mixed or separated, what to bring and how long you can stay. Each listing shows the spa's other facilities and treatments.
