About
Floathaus is a floating wood-fired sauna moored at Muskoka Wharf, where the cold plunge is Lake Muskoka itself. It runs year-round, ice included in winter. Sessions are private rentals, from a 35-minute express to a two-hour soak, with a lakeside lounge between rounds.
Good to know
- Direct lake access: most visitors plunge straight into the water between sauna rounds.
- Cold plunge available on site: use it between rounds for the classic contrast cycle.
- Wood-fired heat: softer, heavier löyly than electric, and the smell of the stove is part of the room.
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
- Swimwear sauna: some or all sessions are taken in swimwear, so pack it.
Hours
- Private sessions by reservation
Reservations recommended; lake plunge year-round
