Heat. Cold. Rest.
One ritual.
A floating spa moored at the Outer Harbour Marina — wood-fired sauna, lake plunge, and a fire pit to come back to. No screens, no rush: move through the cycle at your own pace.
Sauna 85°
Twenty minutes in the wood-fired sauna. Cedar, gentle löyly heat, and the slow loosening of everything you carried in with you.
Plunge 4–20°
Two minutes in Lake Ontario. The cold quickens the blood, steadies the mind, and leaves a deep, clear calm in its wake.
Rest
Wrapped and warm by the fire or out on the deck, letting the body settle. This is where the reset quietly lands — and why you'll come back.
01 · Sauna
02 · Plunge
03 · Rest
Repeat the cycle. You leave feeling calm, refreshed, and ready for the week.
Two ways to be on the water.
Every session is 75 minutes on the water. Bookings open at launch in October — reserve a spot in a shared session, or take the whole floating spa for your group.
Community Session
Book your spot. Up to eight guests share the sauna, the plunge and the fire — small enough to stay quiet.
Private Session
The whole floating spa, just your group. Date night, birthdays, teams, or a slow Sunday with friends.
Arrive 20 minutes before your session to change. Bring a swimsuit and a towel, or rent one on the dock.

Escape, without the drive.
Every version of this feeling lived at a cottage or an hour out of town. We wanted it fifteen minutes from downtown. Celsius is that: sauna, lake, fire — on the water, all year.
— Abbas & Yousuf, founders
