A traditional sauna session isn’t one long sit in the heat. It’s a rhythm: heat, cool down, rest, and back in. The cool-down is part of the experience, which means it deserves a bit of planning when you place an outdoor sauna.
This article covers that space between rounds. For the wider traditional sauna decisions, start with the traditional sauna buying guide.
Short answer: plan for somewhere to cool off and somewhere to sit within a few steps of the sauna door. A shower or a hose works; a cold plunge is the upgrade.
How a traditional session flows
The Finnish rhythm is simple. Heat up in the sauna, throw water on the stones, and after a few minutes of sweating, refresh yourself with a shower or clean water. Then repeat: in Finland, most people have at least two sessions in the hot room (thisisFINLAND).
Between rounds, sit down, cool off, and drink water. Cleveland Clinic recommends plenty of water or an electrolyte drink after sauna use.
What to plan next to an outdoor sauna
| Option | What you need | Notes |
|---|---|---|
| Bench or chairs | A few square feet, ideally sheltered | The simplest upgrade, and the one people use most |
| Outdoor shower | Water supply and drainage | Rinse before entering and cool off between rounds |
| Garden hose or bucket | A tap within reach | Budget version of a shower |
| Cold plunge tub | Space, a level base, and ice or a chiller | The home version of a lake swim |
Placement tips
Keep the cool-down area close to the door, so you’re not walking far in winter. Shelter the bench from wind. Make sure the ground drains, since wet feet and water from the shower will land there.
Here’s what the spec sheet won’t tell you: the barrel’s door direction decides where the cool-down space can go. Settle that before you pour the base. The Canadian Timber Serenity barrel, for example, has a 5mm bronze tempered glass door you’ll want facing your seating area.
Run the numbers on space
The cool-down area needs less room than people expect.
- A bench for two is about 4 ft by 2 ft, or 8 sq ft.
- A round ice bath like The Cold Pod is 30 inches across, about 5 sq ft, plus room to step in.
- A laydown cold plunge such as the Dundalk Polar is 71 by 33 inches, about 16 sq ft.
So a bench and a small ice bath fit in under 20 sq ft beside the door. The bench size is an illustration. The tub sizes are from their listings.
Saunas with the cool-down built in
Some outdoor saunas include the seat. The Canadian Timber Serenity barrel has an integrated front porch with benches, which gives you a sheltered place to sit a step from the door.
A porch uses part of the sauna’s length. Ask the dealer for the length of the hot room as well as the overall length.
If you add cold water
Cleveland Clinic suggests beginners keep cold plunge water at 50 to 59°F and says a session should never run longer than 5 minutes. Going from 180°F air to cold water is a sharp change. Step in slowly, keep the first dips short, and skip it if you have a heart condition unless your doctor has agreed.
A filled 85-gallon tub weighs about 709 lbs. Put it on the ground or a slab, not on the edge of a deck.
Small things that make it work
- A hook outside the door. A robe left inside gets hot and damp. A single cedar hook is $41 in our catalog.
- A non-slip surface. The path from the door to the bench will be wet.
- A light. Winter sessions happen after dark.
- Drinking water within reach. You won’t want to walk to the kitchen.
- Wind shelter. A fence panel or the sauna’s own wall on the windward side.
Adding a cold plunge
A cold plunge tub is the home version of a Finnish lake. If you’re considering one, our cold plunge comparison compares chiller-based tubs on price and warranty. Start gently, and check with your doctor first if you have a heart condition.
Bottom line: the sauna is half the session. Give the other half, the cool-down, a spot within a few steps of the door.
