A natural complement to the salt and Solé treatments provided at Sea Spa, the open-air saltwater pool—which guests can easily access from Sea Spa’s Social Sauna—echoes the natural materials of the spa with lush landscaping that creates a cocoon-like haven. With seasonally heated saltwater, the pool is relaxing and restorative, and in the off-season creates an irresistible effect reminiscent of a hot tub in the snow.

This secluded sanctuary also offers one of the Chelsea’s more serene dining options: Teplitzky’s restaurant, located on the ground floor, features café seating tucked into this retreat. Guests can simply don a robe and stroll over from the Sea Spa, or the saltwater pool, to this causal nook and enjoy a light snack, full meal, or refreshing drink.
