Steam Room vs Sauna: What’s the Difference (and Which Is Right for You)?
A sauna and a steam room look similar and get lumped together, but they create heat in completely different ways — and they feel completely different too. One is dry radiant heat; the other is warm, saturated steam. Here's the real difference, how each one feels, and how to choose the right one for you.
Steam room vs sauna: the quick answer
- A sauna gives you dry, radiant heat — typically 70–100 °C with low humidity — from hot stones on a heater. You control the humidity by throwing water on the stones (löyly).
- A steam room gives you wet heat — a lower air temperature, around 40–50 °C, but 100% humidity — from a steam generator that fills a sealed, tiled room with steam.
Same goal (heat and relaxation), opposite climates: hot-and-dry versus warm-and-wet.
What is a sauna?
A sauna is a timber cabin heated by a stove that warms a bed of stones. The stones radiate a dry heat that takes the air to roughly 70–100 °C. Because the air is dry, that high temperature feels comfortable — and whenever you want a burst of humidity, you throw water on the hot stones to create a wave of steam and heat known as löyly. Saunas can be heated by wood, electricity or gas, and they suit both indoor and outdoor installation — which is why they're the more common choice for a home or garden.
What is a steam room?
A steam room is a sealed, fully waterproof room — usually tiled or made of acrylic — fed by a steam generator. The generator boils water and pumps steam into the room until the air reaches around 40–50 °C at 100% humidity. The temperature is much lower than a sauna, but because the air is completely saturated, it feels intensely warm, wraps around you, and leaves everything (including you) covered in condensation. Because of that moisture, a steam room has to be built as a waterproof, well-drained, non-porous space — which makes it a bigger building job than a sauna.
Sauna vs steam room: the key differences
| Sauna | Steam room | |
|---|---|---|
| Type of heat | Dry, radiant | Wet, saturated steam |
| Air temperature | ~70–100 °C | ~40–50 °C |
| Humidity | Low (you add löyly) | 100% |
| How the heat is made | Stones on a wood, electric or gas heater | A steam generator boiling water |
| Room build | Timber cabin, indoor or outdoor | Sealed, waterproof, tiled/acrylic room |
| How it feels | Hot and dry, crisp air, then steam on demand | Warm, heavy, wet, enveloping |
| Best suited to | Homes and gardens; easy to install | Spas and wet rooms; a bigger build |
How do they feel — and which will you prefer?
This is really the whole decision. A sauna feels hot and dry, with crisp air you can breathe easily, and the option to build the humidity with water on the stones whenever you like — it's the traditional Nordic experience, and many people find the dry heat easier to sit in at higher temperatures. A steam room feels softer and heavier: lower temperature but total humidity, warm mist on your skin, and a more enveloping, spa-like sensation. Neither is objectively better — it comes down to whether you prefer dry radiant heat you can control, or warm wet steam.
Sauna or steam room first?
If you're lucky enough to have access to both — at a spa or gym — a common approach is to start with the sauna (the drier, hotter room) and finish in the steam room, then cool down. But there's no rule: some people prefer the reverse, and plenty simply pick their favourite and stick with it. Whichever order, take it at your own pace, stay hydrated, and step out whenever you've had enough.
Can you have either at home?
You can have both, but they're not equally easy to install. A steam room needs a purpose-built, fully waterproof, tiled and drained room plus a steam generator — realistically a bathroom-scale wet-room project. A sauna is far more practical for most homes: you can put a cabin in a spare room, a garage, or — most popular of all — the garden, and be using it the same week. It's why the home wellness boom has been led by saunas rather than steam rooms.
And if the garden is where yours is going, the heater matters as much as the cabin. A gas sauna needs no electrician and no mains power and is ready in about 15 minutes; electric is the set-and-forget indoor default; wood-fired brings the fire ritual. We cover all three in our wood-fired vs gas vs electric comparison.
Frequently asked questions
What is the difference between a sauna and a steam room?
A sauna uses dry, radiant heat from hot stones — around 70–100 °C with low humidity — while a steam room uses a steam generator to fill a sealed room with 100% humidity at a lower temperature of around 40–50 °C. Sauna is hot and dry; steam room is warm and wet.
Is a steam room hotter than a sauna?
No — a steam room is cooler in air temperature (around 40–50 °C versus a sauna's 70–100 °C), but because the air is 100% humid it can feel just as intense.
Is a steam room better than a sauna?
Neither is better — they offer different experiences. A sauna gives dry, controllable radiant heat and is easier to install at home (indoors or in the garden); a steam room gives soft, enveloping wet heat but needs a purpose-built waterproof room.
Should you use the sauna or steam room first?
A common approach is sauna first (drier and hotter), then the steam room, then a cool-down — but there's no strict rule. Go at your own pace and stay hydrated.
Can you have a sauna or steam room at home?
Both are possible, but a sauna is far more practical: a cabin can go indoors or in the garden and be used within days, whereas a steam room needs a purpose-built, waterproof, tiled room and a steam generator.
