KOS Sauna

Kos is New York's first public floating sauna, located in the marina at Lago by Druthers on Saratoga Lake. We are on a mission to help people be happy, healthy, and connect through heat. Inspired by Norway’s stunning fjord saunas, combined with the rich heritage of healing waters in Saratoga Springs, Kos brings an authentic Nordic wellness experience to upstate New York - just 3 hours north of Manhattan.

“Kos” (pronounced “cozy” without the y) in Norwegian means warm and simple pleasures, often shared with others. We are a year-round, community-driven business offering communal sessions, private rentals, annual memberships, classes and rituals, team-building, and custom events in our 15-person floating sauna and roof terrace.

Why should you consider adopting a regular sauna practice? Humans have boosted physical and mental health with cycles of heat, revitalization, and rest for centuries. Benefits include reduced blood pressure, heart disease, risk of stroke, Alzheimer’s, respiratory disease, arthritis, headache, and flu. Recent studies show that the brain is more focused and efficient post-sauna, enhancing focus and concentration. It’s also flushed with β-endorphins, giving your day a euphoric boost!

For people seeking improved health, less stress, more joy, and social connection, Kos provides an invigorating experience in nature year-round at a price point accessible to all. For whatever reason your visit, we look forward to welcoming you into the warmth at Kos!

Kos will open to the public during the last week of September, 2025.
