What to Expect Your First Time at a Sauna and Cold Plunge Studio
First times are uncomfortable. Not because sauna houses are complicated — they’re not — but because not knowing what to expect creates friction that the experience itself would dissolve immediately.
This is everything you need to know before you arrive. By the end of it, the only thing left will be to actually go.
What a sauna and cold plunge studio?
A sauna and cold plunge studio is a dedicated contrast therapy facility — a space built specifically around the practice of alternating heat and cold with intentional rest between cycles. It is not a spa. It is not a gym. It is not a wellness clinic.
It’s closer to a bathhouse in the European tradition — a communal space for a shared physical practice, stripped of the service-heavy, treatment-focused model of a spa and the performance-focused model of a gym. You come in. You heat. You plunge. You rest. You repeat.
At Signed Off, a session is 90 minutes. You move through the space at your own pace, following the three-cycle protocol — sauna, cold plunge, rest lounge — as many times as feels right within your session window.
Before you arrive:
What to bring
A swimsuit is the only essential. We provide towels, robes, and sandals — so you genuinely don’t need to bring much. A reusable water bottle is worth having. Leave your phone in the locker if you can — not because we ask you to, but because you’ll get more from the session without it.
What to eat and drink
Arrive well-hydrated. The sauna produces significant fluid loss through sweat and you want to begin from a good baseline. Don’t eat a large meal immediately before — a light snack two hours before is fine. A full stomach in 85°C heat is not comfortable.
How to get there
We’re at 108–1295 Riverbend Road in the West 5 community, London Ontario. There’s parking on site. We’re a short walk from the Legacy Square area of West 5.
When you arrive:
You’ll check in, get oriented, and be shown to the change rooms. The process is simple — lockers for your belongings, towels are provided. Robe and sandals are available to rent.
A staff member will walk you through the protocol if it’s your first time — where everything is, how the cycles work, how long to aim for in each environment. This takes about five minutes and removes any uncertainty before you begin.
From there, the session is yours. There’s no schedule to follow, no instructor to keep up with, no performance required. You move at your own pace.
The Sauna
The sauna is where most people begin and where most people find their rhythm.
Our sauna runs at 80–90°C and seats twenty people. It’s a communal space — you’ll be in there with other guests. This is intentional. The sauna is better with people in it. The quiet company of strangers sharing something warm together is part of what makes it work.
What to expect in your first few minutes
The heat will feel intense immediately. Your body is responding to a genuine thermal challenge and it will take three to five minutes to settle. Most people feel an urge to leave in the first two minutes. Most people who stay past that point feel a distinctive shift into relaxation — muscles loosening, breathing slowing, the day starting to recede.
Aim for 10 to 15 minutes in the sauna for your first cycle. Less if you need to. More if you’re comfortable. There is no correct amount of time — there is only what your body tells you.
Breathe slowly. Find a comfortable position. Let the heat do its work.
The Cold Plunge
This is the part people are most nervous about. It is also the part most people describe as their favourite by the end of the session.
Our cold plunge runs at 2–6°C and holds six people. It is genuinely cold. There is no way to fully prepare for it except to get in.
What to expect
The first ten seconds are the hardest. Heart rate spikes, breathing goes sharp and shallow, every instinct tells you to get out. This is the cold shock response — a normal physiological reaction that passes within 30 to 60 seconds if you breathe through it.
The single most effective thing you can do on entry is exhale slowly and deliberately. This tells your nervous system you are safe and accelerates the transition through the shock phase.
After the shock passes — and it will pass — something else arrives. A clarity and aliveness that most people have never felt before. This is the norepinephrine and dopamine response to cold exposure, and it is neurochemical. Not placebo. Not willpower. Chemistry.
Aim for 1 to 3 minutes in the cold plunge. Come out when the cold starts to feel manageable, not when you feel numb.
The most common thing people say after their first cold plunge: I can’t believe I just did that and I want to do it again.
The Rest Lounge
Rest is not waiting for the next cycle. It’s part of the protocol — as important as the heat and the cold.
The rest lounge is where your body integrates the work it’s been doing. Heart rate returns to baseline. The nervous system recalibrates. Blood flow redistributes. The dopamine and norepinephrine response fully arrives. The distinctive post-contrast feeling — the one that’s hard to describe and easy to recognise — happens here.
Aim for 5 to 10 minutes of rest between cycles. Sit. Breathe. Be still. Talk to people if that feels right. Leave your phone in the locker.
This is the phase most first-timers underestimate and most regulars protect fiercely.
Cycling through
After your first rest, you’ll likely feel ready to go back into the sauna. This is the point. You do it again.
Two to three full cycles within a 75-minute session is a good target for most people. By the second cycle the sauna feels more familiar, the cold plunge feels more manageable, and the rest feels more earned. By the third cycle you’ll understand why people make this a weekly practice.
A note on finishing: we recommend ending your final cycle with the cold plunge rather than the sauna. Finishing cold produces a more sustained dopamine elevation and activates the metabolic benefits of cold thermogenesis. Most regulars do this instinctively within a few sessions.
After your session
Get dressed slowly. Give yourself time to return to the world gradually rather than rushing straight back into stimulation.
Most people report feeling a distinctive combination of physical relaxation and mental clarity in the hours after a contrast session. Energy without agitation. Calm without fatigue. The post-contrast state is worth protecting.
Drink water. Eat something. Sleep well that night — most people do.
A few things that might surprise you:
It’s quieter than you expect
The sauna has a particular quality of silence — not the silence of a library but the silence of a shared experience. People talk, but not loudly, and not continuously. Phones aren’t in the space. The noise level is genuinely low.
The community aspect is real
The strangers you share a sauna with have a way of not feeling like strangers by the end of a session. Something about the shared experience — the heat, the vulnerability, the post-plunge glow — produces genuine warmth between people. Don’t be surprised if you find yourself in a good conversation.
You’ll want to come back
This is almost universal. Not in a pressured way — nobody is going to push you. Just in the natural way of having discovered something that makes you feel good and wanting to feel it again.
