Othership Flatiron in New York City’s vibrant Flatiron District offers a transformative thermal journey that blends ancient hydrotherapy practices with modern wellness experiences. At the heart of this sanctuary is a 90-person performance sauna—one of the largest in North America—designed to deliver clean, invigorating heat up to 185°F (85°C). Enhanced with aromatic snowballs, the sauna creates a humid environment that feels even hotter, promoting deep relaxation and rejuvenation.
Complementing the heat is a suite of eight ice baths maintained between 32–40°F (0–4°C), including custom 4-person tubs perfect for shared experiences. This deliberate contrast of hot and cold immersions forms the core of Othership’s hydrotherapy offerings, stimulating circulation, enhancing recovery, and fostering mental clarity. Beyond the physical benefits, the spa’s social commons—featuring amphitheater-style seating around a cozy fireplace—provides a welcoming space for community connection and reflection. Whether seeking personal renewal or shared moments, Othership Flatiron invites guests to embark on a holistic wellness journey that nurtures both body and spirit.
