How To Do A Finnish-Style Sauna Session At Home
A six-step Finnish-style sauna session for a home sauna – heat, bench, timing, löyly and scent – with the simple accessories that turn it into a ritual.
Published October 6, 2026 · 6 picks
A Finnish sauna session is not an endurance test. It is a loop: get hot, throw water on the stones, cool down, rest and go again. Give it an hour or more and nothing else to do. The six steps below follow one round in order, each built around one simple accessory, and the last section closes the loop.
One note before you start: this guide is for a traditional sauna with a stone-topped heater that is made to take water. In an infrared cabin, or with a heater whose manual says to keep it dry, skip the water in Steps 5 and 6.
Step 1 · Heat the room and read the dial
Switch the heater on well ahead – most electric heaters need 30 to 60 minutes, and the stones have to be fully hot before they make good steam. Most Finnish-style sessions run between about 150 and 195 °F (65–90 °C), measured near head height on the upper bench, with dry air before any water is thrown.
A combined gauge such as the defull thermometer and hygrometer shows both values on one dial, so you can see when the room is ready and what each ladle of water does to the humidity.
- New to sauna? Start at the low end, around 150–160 °F (65–70 °C).
- Read the gauge from the bench, not from the door – temperature changes a lot between floor and ceiling.
- While the room heats, fill the bucket and set out a towel to sit on and a glass of water for afterwards.
Step 2 · Rinse off and cover your head
Shower before you go in. Clean skin is the Finnish custom and keeps the benches fresh. Dry off, take a towel to sit on, and leave the phone, watch and jewelry outside – metal gets hot fast.
Then the hat. On the upper bench your head is in the hottest air in the room, and a wool felt sauna hat puts an insulating layer in between. Many people find the heat easier to sit in with a covered head; wear it dry, or wet it with cool water first.
Step 3 · Settle on the bench
Heat rises, so the bench you choose is your real thermostat: the upper bench is the hottest seat, the lower bench is noticeably milder. Start low if you are new, and move up when it feels good.
Spread your towel, sit back and get comfortable enough to stay still. A loose backrest like the TOLHYUN S-shape leans between bench and wall and takes the flat boards out of the equation. If there is room, put your feet up on the bench so your whole body sits in the same layer of heat.
A Finnish sauna is a quiet place. No screens, no music needed – low talk or none at all.
Step 4 · Turn the glass
Turn the 15-minute sand timer as you sit down. A first round of 8 to 12 minutes is plenty for most beginners; regulars often stay 10 to 15. The sand is there to remind you, not to challenge you – there is no prize for staying until it runs out.
- Leave right away if you feel dizzy, sick or get a headache.
- Later rounds are usually shorter than the first.
Safety: do not use the sauna after drinking alcohol or when you feel unwell. If you are pregnant, have a heart condition or take medication that affects blood pressure, talk to your doctor first. Children need an adult beside them, the lower bench and much shorter rounds.
Step 5 · Throw the löyly
Löyly is the Finnish word for the steam that rises when water meets hot stones – and for the feeling it brings. After a few minutes of dry heat, take one ladle from the cedar bucket and pour it slowly across the stones. The humidity jumps, the heat feels sharper for a minute, then softens again.
- One ladle at a time. Wait until the wave has passed before you throw another; two or three per round is plenty in a small room.
- Ask before you throw. Whoever sits on the top bench feels it most.
- Use clean tap water only – no pool water and nothing salty.
- Keep your arm long and your face back. The steam comes up fast.
Safety: water goes only on a heater that is built for it, and only on the stones. Check your heater’s manual, keep the bucket where nobody can kick it over, and never pour water on an infrared heater.
Step 6 · Add a little scent
This step is optional, and one scented round per session is enough. Stir two or three drops of eucalyptus essential oil into a full bucket of water. Oil floats, so stir again before each ladle. If the room wants more, add a drop next round.
Safety: never put undiluted essential oil on the stones or the heater – it is flammable. Keep the bottle outside the hot room and away from children and pets, and skip the scent if anyone in the sauna is pregnant, has asthma or is sensitive to fragrance.
Cool down, rest and repeat
When the sand runs out – or sooner – step out. Cool off in fresh air or under a cool shower, starting with your feet and hands. A cold plunge or a roll in the snow is the famous version, but a sudden cold shock is not for everyone; a gradual cool-down works just as well for the ritual.
Then sit down for at least as long as you were in the heat, and drink water. When your skin is cool and your breathing is calm, go back in for the next round. Two or three rounds make a full session.
To close, rinse off, empty the bucket and hang the ladle and the hat up to dry. Leave the sauna door open for a while so the benches dry out. Something to drink and something salty to eat afterwards belongs to the tradition as much as the heat does.

01
defull Stainless Steel Sauna Hygrometer Thermometer with Color-Coded Dial, 5 in
One dial for temperature and humidity tells you when the room is ready and what each ladle of water does to it.
A sauna without a gauge is guesswork: the same room can feel mild at 150 °F (65 °C) with dry air and fierce a minute after water goes on the stones. This defull gauge puts both readings on one 5 in (12.7 cm) dial – temperature from 70 to 250 °F (21–121 °C) on the upper arc, relative humidity from 0 to 100% on the lower one.
The dial is color-coded: per the listing, a red band covers 150–212 °F (66–100 °C), the range most traditional sessions sit in, and a green band marks 0–20% humidity, the dry starting point before any löyly. It reads in Fahrenheit only, and the listing gives neither an accuracy tolerance nor mounting details, so treat it as a guide rather than a lab instrument.
Tip: Hang it at about head height for someone seated on the upper bench, on a wall away from the heater and the door – right above the heater it will always read too high.
02
Halsa Sauna Hat – 100% Natural Wool Felt Bucket Hat for Men & Women
A wool felt hat puts a layer between your head and the hottest air in the room, up where the top bench sits.
A wool hat in a hot room looks odd until you remember that heat rises: on the upper bench your head sits in the hottest air in the sauna while your feet are in the coolest. Felted wool is a slow conductor of heat, which is why the felt hat is a fixture of Baltic and Russian bathing and a common sight in Finnish saunas too. This Halsa version is a plain gray bucket hat in 100% wool felt, pull-on, one size.
The maker says it insulates the head and helps buffer hair and scalp from the heat, and suggests soaking it in cool water first. Those are the maker’s claims; the practical point is that many people simply find the upper bench more comfortable with a covered head. It is hand wash only.
Tip: Hang it up to air-dry outside the hot room after each session – wool left damp in a bag turns musty.
03
TOLHYUN Sauna Backrest, Wooden Slip-Resistant S-Shape
A curved pine backrest gives a flat sauna wall something to lean on, so sitting still comes easily.
Finnish benches are flat boards against a flat wall, which is fine for ten minutes and less so by the third round. A loose backrest fixes that without changing the sauna itself. This one is an S-shaped pine frame with round crossbars, 19.7 × 15.7 in (50 × 40 cm), that leans between the bench and the wall; pads wrapped around the four corners keep it from sliding.
The listing is written mostly with infrared cabins in mind, where the maker says the frame keeps your back off the heater panels. In a traditional sauna it does the simpler job of a comfortable lean. At 1.7 lb (0.77 kg) it moves easily between the upper and lower bench. The listing states no finish and no load rating.
Tip: Drape your towel over the backrest as well as the bench – in a Finnish sauna, bare skin sits on cloth, not on wood.
04
SuLiao Sauna Sand Timer Hourglass 15 Minute, Rotating Wood, Black Sand
A 15-minute sand timer on the wall keeps the round honest and the phone out of the heat.
Phones and smartwatches do not belong in a hot sauna, and most are not built for that heat anyway. The traditional answer is a sand timer on the wall. This one runs 15 minutes, with marks at 5, 10 and 15 so a shorter round is easy to read off. The glass tube sits in a wooden frame that rotates on its wall bracket – turn it when you sit down, and again for the next round.
The maker gives the accuracy as ±10%, so treat it as a guide, not a stopwatch. That is the right attitude to sauna time in any case: your body is the real timer, and you leave when you have had enough, whatever the sand says.
Tip: Mount it at seated eye level on a side wall, well away from the heater, so you can read it from the bench without moving.
05
Northwood Sauna Bucket and Ladle Set, Canadian Red Cedar, 1 Gallon (4 Liters)
A cedar bucket and a ladle are all it takes to turn dry heat into the soft wave of steam Finns call löyly.
Löyly – the wave of steam that rises when water hits hot stones – is the center of a Finnish sauna, and it takes two tools: something to hold the water and something to throw it with. This Northwood set pairs a 1 gallon (4 L) red cedar bucket with a ladle that holds 3.4 fl oz (100 mL), which makes each throw a measured splash instead of a flood.
A removable liner made from recycled plastic sits inside the bucket. It keeps standing water off the wood and lifts out for rinsing. The listing does not state the ladle’s length, so with a deep or guarded heater it is worth checking that you can reach the stones without leaning over them.
Tip: Fill it with clean tap water before you go in, and empty and dry it when you are done – a wooden pail left full between sessions does not stay nice for long.
06
Cliganic Organic Eucalyptus Essential Oil, 100% Pure, 1 Fl Oz
A few drops of eucalyptus oil stirred into the bucket water scent one round without overpowering the room.
Scent is optional in a Finnish sauna – plenty of bathers want nothing but hot wood and water – but a little eucalyptus in the löyly water is one of the most common additions. This Cliganic oil is a single ingredient, certified USDA Organic, and the maker says each batch is tested for purity by an independent lab.
It is sold for diffusers, not saunas, so the listing gives no sauna instructions. The general practice is heavy dilution: a few drops stirred into a full bucket of water, never neat oil on the heater. Essential oils are concentrated and flammable, so the bottle stays outside the hot room and out of reach of children and pets.
Tip: Start with two or three drops in a full bucket and stir before each ladle, because oil floats on water – you can add more next round, but you cannot take it back out of the air.
