A Finnish sauna is hotter and drier: 80–100 °C at face height with 5–20% humidity, from an open stove you ladle water onto yourself. A Russian banya runs cooler and much wetter, usually around 60–70 °C at 40–70% humidity, with a closed stone chamber, a soaked birch or oak venik and a felt hat on nearly every head. They are the same family of wood-fired bathhouse with the same cold plunge between rounds; what differs is the steam, the whisk, and how much of a social event it all is.

In Russian, a sauna is simply the "Finnish banya" (Wikipedia). And the oldest written description of a banya is an outsider's complaint. In the 12th-century Primary Chronicle, the Apostle Andrew reports that the Slavs around Novgorod heat wooden bathhouses "to extreme heat," lash themselves with young reeds "so violently that they barely escape alive," then drench themselves in cold water, and "make of the act not a mere washing but a veritable torment" (Serge Zenkovsky's translation, via Wikipedia).
What is the difference between a banya and a sauna?
Humidity, the stove and the whisk. Everything else, from the length of a round to what people drink afterwards, follows from those three.
| Finnish sauna | Russian banya | |
|---|---|---|
| Air temperature | 80–100 °C at face height | About 60–70 °C in a well-steamed public banya; some run hotter |
| Humidity | 5–20% between ladles | About 40–70% |
| Stove | Kiuas: stones heaped on top, usually open to the room | Masonry stove with a closed rock chamber and a small opening for water |
| How the steam is made | You ladle water onto the open stones (löyly) | Water goes through the hatch onto very hot rocks, often thrown by an attendant |
| Whisk | Vihta or vasta: birch, used gently, mostly in summer | Venik: birch, oak, linden or eucalyptus, soaked first, used hard, often by someone else |
| Rooms | Changing room, washing room, hot room | Predbannik (changing and resting), washing room, parilka (steam room) |
| A round | 8–15 minutes; three rounds is typical | 10–15 minutes; three or four rounds |
| Cooling off | Lake, sea, snow, cold shower, avanto (a hole in the ice) | Cold pool, a bucket over the head, snow, an ice hole |
| On your head | Optional; the hat is a recent import | A felt hat, standard; often sold with felt mitts |
| Between rounds | Water and quiet | Tea, mineral water or beer, snacks, conversation |
| What people say | "Olipa hyvät löylyt!" (What great löyly!) | "S lyogkim parom!" (With light steam!) |
| House spirit | Saunatonttu, the sauna elf | Bannik, who lives behind the stove |

Is a banya hotter than a sauna?
On the thermometer, usually not; on your skin, often yes. The Moscow Times' beginner's guide puts a public banya at 60 to 70 °C once the attendant has the steam "just right," against 80–100 °C in a Finnish sauna (The Moscow Times). But water vapour condenses on skin and hands over heat far faster than dry air, and moist air slows the evaporation of sweat, which is why a banya at 65 °C can feel fiercer than a sauna at 90 °C.
Measured strain agrees. In a 2026 University of Jyväskylä study of 50 adults, humidity raised heart rate and core temperature independently of air temperature, even though temperature remained the bigger factor (University of Jyväskylä). A lower reading on a banya thermometer is not the same thing as an easier room.
Banya numbers also vary more than sauna numbers. Andrei Fomin, founder of London's Banya No.1, quotes 60–70 °C at 60–70% humidity for his steam room (Spabreaks), while Wikipedia notes that banya temperatures "often will exceed 93 °C." There is no single banya number, only a cooler, wetter tendency.
How is a banya stove different from a sauna stove?
In a Finnish sauna you throw water onto the stones; in a banya you throw it into a closed chamber. Most Finnish heaters, including the common electric kind, carry their stones on top, open to the room, while the heat-storing type keeps them under an insulated lid until bathing starts and can hold anything from a few dozen to several hundred kilos of stones (Finnish Sauna Society). A traditional banya stove has three compartments: a firebox fed from the entrance room, a rock chamber with a small hole to throw water into, and a water tank on top that heats the washing water (Wikipedia).
The closed chamber is what makes the banya's prized lyogkiy par, "light steam." A small amount of water on very hot rocks flashes into fine vapour, while too much at once gives a cool, clammy steam. Fomin describes his London furnace as about a tonne of cast iron heated to 700 °C, against stones at roughly 250 °C in a typical sauna stove. Those are his figures, not independent measurements, but they show the principle: hotter rock, behind a door, fed small amounts of water.
Both traditions started in the same smoke-filled room. Russians call it a "black" banya (po-chyornomu), where smoke escaped through a hole and darkened the walls, as opposed to a "white" banya with a chimney (po-belomu). Finns call theirs a savusauna, the smoke sauna, which takes hours to heat and leaves a faint scent of smoke, resin and tar (Finnish Sauna Society).
What is a venik, and how is it different from a vihta?
Both are bundles of leafy branches; the difference is force and who swings them. A Russian venik of birch, oak or linden is soaked in very hot water for 10–15 minutes, then used to drive hot air onto the body, often by a second person. By banya etiquette you can ask anyone in the parilka to steam you, and it is meant to feel like a massage, not a beating (Learn Russian in the EU). In public banyas you can pay an attendant to do it (The Moscow Times).
The Finnish vihta, or vasta in the east, is a birch bundle used more gently, mostly in summer, and you will rarely meet one outside Finland, the Baltics or a dedicated banya (sauna etiquette for your first time). In a Finnish sauna the steam does the work; in a banya, the venik pushes it at you.
Why do people wear felt hats in the banya?
Because the banya is where the felt sauna hat comes from. The Moscow Times' guide tells first-timers to bring "a felt or wool hat for the steam room," or to buy a felt bannaya shapka at the ticket booth along with a venik, and The Globe and Mail found felt and wool hats "a ubiquitous sight" in Toronto's Russian banyas, next to mitts that protect your hands from blisters while handling hot veniks (The Globe and Mail).
We say this wherever it comes up: the felt hat is a banya tradition, not a Finnish one, and it reached Finnish saunas later. In a banya's 40–70% humidity a wool hat takes on water, but merino absorbs about 35% of its dry weight before it saturates, so it keeps working through a round (sauna vs banya vs steam room vs infrared). Afterwards, give it a full day to dry flat; how to wash a wool sauna hat covers the rest.
Ours is pressed from a single piece of 3 mm merino felt with no seams: the Lanoviss merino wool sauna hat, $59.99 CAD, one size for heads of roughly 55–61 cm.
Which should you try first, a banya or a Finnish sauna?
| If you… | Start with |
|---|---|
| Like dry, intense heat you control one ladle at a time | Finnish sauna |
| Want a long social evening with food, tea and a massage | Banya |
| Find humid air hard to breathe | Finnish sauna, lower bench |
| Want the full hot–cold ritual with a whisk | Banya, with a venik session |
| Are bringing a felt hat | Either; it was made for the banya |
The safety rules are the same in both: drink water, leave when you feel dizzy, and keep the beer or vodka until after the last round. Both are part of banya culture, and a Finnish forensic review found alcohol involved in half of all sauna deaths in Finland between 1990 and 2002 (Journal of Forensic Sciences).
Where can you try a banya in Canada or the US?
Toronto has the deepest bench. The Globe and Mail's round-up of GTA banyas ran from the Ambassador Club in North York, open since the 1960s and "the granddaddy of banyas in the GTA," to Sanduny Sauna Spa in North York and South-Western Bathhouse and Steamul Sauna in Mississauga, many with separate women's and men's nights (The Globe and Mail). Prices and hours in that article date from its publication, so check before you go.
In New York, the Russian & Turkish Baths at 268 East 10th Street has been open since 1892 and is run on alternating weeks by two families of owners (Wikipedia).
Frequently asked questions
What is the main difference between a banya and a sauna?
Humidity and the stove. A Finnish sauna runs 80–100 °C at 5–20% humidity from an open stove; a Russian banya usually runs around 60–70 °C at 40–70% humidity, with a closed rock chamber that makes fine "light steam," plus a soaked venik and a felt hat.
Is a banya the same as a steam room?
No. A banya is a wood-lined room heated by a stone stove at around 60–70 °C. A steam room runs about 40–48 °C at close to 100% humidity and is fed by a steam generator rather than a stove full of stones.
What does "s lyogkim parom" mean?
Literally "with light steam." It is what the attendants say to you as you leave a Russian banya: a wish that your steam was light and refreshing.
Why do people hit each other with branches in a banya?
The venik, a soaked bundle of birch or oak branches, pushes hot, humid air onto the skin and works as a massage. Done properly it shouldn't hurt; the Apostle Andrew's "veritable torment" in the Primary Chronicle is an outsider's account.
What do you wear in a banya?
In single-sex sections, nothing or a sheet, plus a felt hat and plastic slippers. In a mixed public banya, wrap yourself in a towel or wear a swimsuit.
Is a "Russian sauna" the same as a banya?
Yes. In North America "Russian sauna" usually means a banya, and in Russian the Finnish sauna is called the "Finnish banya."
Can you wear a sauna hat in a banya?
Yes; the banya is where the felt sauna hat comes from. It will absorb some moisture in a banya's humidity, but wool keeps insulating well before it is saturated. Dry it flat for a full day afterwards.
