KOS Sauna is a year-round, floating public sauna on Saratoga Lake in Saratoga Springs, NY, offering social sauna sessions, private rentals, memberships, and community-driven wellness inspired by Nordic traditions.
What Is KOS Sauna?
“KOS” (pronounced “cozy” without the y) is a Norwegian word that captures warmth, simplicity, and shared pleasures. Inspired by years spent living in Oslo, KOS Sauna brings authentic Nordic sauna culture to upstate New York. Drawing from Norway’s iconic fjord saunas and Saratoga Springs’ deep wellness heritage, KOS Sauna offers a restorative experience rooted in community and connection.
As New York’s first public floating sauna, KOS Sauna invites guests to slow down, reset, and experience the powerful balance of heat, water, and rest—just three hours north of Manhattan.
A Floating Sauna Experience on Saratoga Lake
Moored at the marina at Lago by Druthers, KOS Sauna operates from Marka, a custom floating sauna boat designed for comfort and immersion in nature. Each visit includes access to:
- 15-person Finnish-style floating sauna
- Refreshing lake plunge in Saratoga Lake
- Rooftop terrace with lake views
- Shared and private changing areas
- Drinking water sourced from Saratoga’s mineral springs
Sauna temperatures range from 176–230°F, with traditional bursts of steam known as löyly. Guests are encouraged to follow cycles of heat, plunge, and rest at their own pace.
