Equinox Hotel Hudson Yards

This is the sauna for people who take the sauna seriously. Equinox built its first hotel around a 60,000-square-foot wellness floor, and the heat experience is properly engineered — dry sauna, steam, and a hot-to-cold contrast circuit designed for actual recovery, not just a post-shower glow. The aesthetic is dark, moody, and faintly clinical in the best way; you feel like you're doing something good for your body, because you are. Rooms upstairs are sleek and built for sleep. It's not the cosiest atmosphere in the city — more performance than romance — but if you want a big, capable, contrast-bathing setup attached to your bed, nothing else in New York competes. Guest access to the spa heat is included; book treatments separately if you want hands-on recovery too.
