I have spent 8 years in saunas. Public ones, private ones, Finnish wood-fired saunas, electric ones, infrared cabins. In that time I have wasted money on accessories I never used again and found a few that I now consider essential.
This is not a list of everything you can buy for a sauna. These are the items I actually use and would buy again if I was setting up a new sauna from scratch.
Before I get into what is worth buying, three quick skips: Bluetooth sauna speakers (you are there to disconnect), fancy branded oil blends (pure eucalyptus for $10 beats any $40 blend), and plastic anything inside the hot room (heat plus plastic equals microplastics you do not want to breathe). Now here is what is actually worth buying.
1. Sauna Hat — Makes a huge difference
If you only buy one thing from this list, make it a wool sauna hat.
Here is why it matters: the air near the ceiling of a sauna can be 20-40 degrees hotter than at bench level. Your head and ears take the worst of it. A wool hat insulates your head, lets you stay in longer, and makes higher temperatures comfortable instead of painful.
Go with 100% natural wool. Felt hats hold their shape better than knitted ones. Avoid synthetic materials — they defeat the purpose.
One benefit most people miss: sauna hats protect long hair from heat damage and dryness, so they are not just a guy thing — anyone with long hair should use one. My favorite trick is soaking the hat in cold water before each session. It buys you several extra minutes of comfort inside and makes high temperatures much more bearable. If I had to pick just one sauna accessory to use for the rest of my life, it would be the hat without question. I wrote a full guide on choosing the right one.
What to look for:
- 100% wool (not synthetic blends)
- Thick enough to actually insulate (thin fashion hats are useless)
- Fits snug but not tight
2. Thermometer and Hygrometer — Know Your Conditions
You cannot have a good session if you do not know the temperature and humidity inside your sauna. Many people just guess, and that is why their sessions feel inconsistent.
A combo thermometer/hygrometer mounted at head height tells you exactly what conditions you are sitting in. Once you start tracking this, you will find your personal sweet spot and be able to recreate it every time.
I track every session because it lets you actually progress — if you did 3 minutes at 80°C last time, push for 5 next time. I run mine hot, usually 70-90°C, sometimes over 100°C for a few minutes. The hotter the session, the better my sleep that night. Humidity matters too, especially for skin — a humid session before a blackhead extraction appointment softens the skin and makes the whole thing less painful.
Once you know what conditions you are chasing, the device itself is simple. A good combo unit gives you both readings at a glance, stays accurate over years of heat exposure, and is readable through steam from across the sauna.
What to look for:
- Combo unit (temperature + humidity in one device)
- Fahrenheit and Celsius display
- Heat-resistant construction rated for sauna temperatures
- Easy to read from the bench
3. Sauna Bucket and Ladle — Essential for Traditional Saunas
If you use a traditional sauna with a heater and stones, a bucket and ladle is not optional. Throwing water on the stones — the Finns call it löyly — creates that burst of steam that transforms a dry room into an intense experience.
The material matters. Wooden buckets (cedar, pine, or birch) look great and feel authentic, but they need a metal liner to prevent leaking. Stainless steel buckets with wooden handles are another practical option for daily use.
Always throw water on the stones, and add a few drops of natural menthol or eucalyptus oil to the water first. The löyly carries the scent through the whole sauna, opens up your nose, and makes breathing easier — especially helpful for anyone with allergies or a stuffy nose. Go with a cedar bucket over metal. The wood gives a more authentic sauna feel, and metal handles can get burning hot if you touch them by accident.
What to look for:
- 1-2 gallon capacity is plenty
- Ladle handle long enough so your hand stays away from the steam
- Matching set looks better and usually cheaper than buying separately
4. Sauna Headrest — The Comfort Upgrade You Did Not Know You Needed
Lying flat on a wooden bench for 15-20 minutes is fine. Doing it with a proper wooden headrest cradling your neck is significantly better.
Most people do not think about this until they try one. The ergonomic curve takes pressure off your neck and shoulders, and you end up staying in longer because you are actually comfortable instead of shifting around trying to find a position that works.
If there is enough space to lie flat on your back, that is hands down one of the best sauna experiences. My tip to make it even better: when you lay out your sauna towel on the bench, extend it so the end covers the headrest too. That way your head rests on the towel instead of directly on the wood — softer, more hygienic, and it soaks up any sweat from your hair. Lie down, let your head settle into the curve, and focus on your breath. It sounds like a small upgrade until you try it — after using one, sitting upright in a sauna starts to feel like the inferior option.
What to look for:
- Curved or dual-curve design that supports the natural shape of your neck
- Cedar, aspen, or abachi wood (heat-resistant and splinter-free)
- Open slat design or non-slip base so it stays stable on the bench
- Wide enough to actually cradle your head (some cheap ones are too narrow)
5. Essential Oils and Sauna Scents — Underrated Game Changer
A few drops of eucalyptus oil in your bucket water before you throw it on the stones completely changes the atmosphere. The steam carries the scent through the entire room and it opens up your breathing instantly.
Not all oils work well in saunas though. Eucalyptus, pine, and birch are the classics for a reason. Lavender works if you want a more relaxing session. Avoid anything synthetic or overly sweet — it gets nauseating in the heat.
My go-to oils are menthol, mint, eucalyptus, and sometimes orange — I even mix them together occasionally. Lavender is also a great choice if you want something more relaxing. One warning: I once accidentally bought scent pods designed for diffuser machines instead of pure natural oils — do not make that mistake. Always go for 100% natural oils. Skip the artificial “fancy” flavors with made-up names — the simple, classic scents like eucalyptus, mint, and even cinnamon are the ones that actually enhance the sauna experience instead of just smelling fake. Add the oil to your bucket water and pour it onto the stones, but stick to 4-5 drops maximum. Too much and you will actually struggle to breathe inside.
What to look for:
- 100% pure essential oils (not fragrance oils)
- Eucalyptus, pine, birch, or lavender are the safe choices
- Add to bucket water, not directly onto stones (direct contact can create harsh fumes)
- A little goes a long way — 3-5 drops per session
6. Sauna Wood Oil — Protect Your Investment
This is the boring one that nobody talks about but everyone needs. Sweat, moisture, and heat break down wood over time, and dedicated sauna cleaners barely exist on the market. What experienced sauna owners actually use is sauna wood oil — a protective treatment that nourishes the wood, prevents drying and cracking, and extends the life of your sauna by years.
Do not use regular furniture polish or household wood cleaners. Most contain chemicals that release fumes when heated, which defeats the entire purpose of being in a sauna. Look for solvent-free, food-safe oils specifically made for sauna wood.
The single most important habit costs nothing though: leave the sauna door open after every session so the wood dries out properly. Trapped moisture is what causes smell and wood damage over time. People spend thousands on a sauna and then ruin it in two years because they never air it out or treat the wood. Treat it like any other investment you want to last.
What to look for:
- Solvent-free, food-safe formula (no harsh chemicals or fumes when heated)
- Pharma-grade paraffin oil or natural cedar oil
- Safe for all sauna wood types (cedar, hemlock, aspen, pine)
- Covers enough square footage to treat your entire sauna
7. Hourglass Sand Timer — Simple but Useful
Your phone does not belong in a sauna. The heat damages electronics, and checking your phone defeats the whole purpose of being in there.
A wooden hourglass sand timer is the simplest solution. Flip it when you sit down, watch the sand fall, and you know exactly how long you have been in without needing any technology. Watching the sand physically drop is different from glancing at a digital number — seeing the time left in front of you somehow helps you commit to finishing the full session instead of stepping out early.
There are two styles worth considering: wall-mounted timers that stay fixed in place inside your sauna, and freestanding flip-style timers you can place on a bench and move around. Wall-mounted is the classic choice if you have a dedicated spot for it. Freestanding is more flexible, especially if you use different saunas or want to bring it with you.
What to look for:
- 15-minute timer (the most practical duration — flip it again if you want longer)
- Heat-resistant wooden housing rated for sauna temperatures
- Wall-mounted or freestanding depending on your setup
- Large enough to see clearly from the bench through steam
8. Sauna Towel — Hygiene Matters
Sitting directly on hot wood works, but a dedicated sauna towel is better for hygiene, especially if multiple people use the sauna. It absorbs sweat, protects the wood, and feels more comfortable than bare timber. In Finnish sauna culture, sitting on a towel is standard practice — and it should be yours too.
Always bring two towels to a session. One is a thinner sheet-style sauna towel you lay down on the bench to sit or lie on — you never know who was sweating on that wood before you, and it is basic hygiene. The second is for showering afterwards. If you want the full experience, bring a third and skip the bathing suit entirely, wrapping the towel around you instead — it actually feels more comfortable, and it is how it is done in proper Finnish sauna culture.
Stick with natural fibers. Linen and Turkish cotton are the two traditional choices, and each has its strengths. Linen is crisper, more durable, and dries faster — it actually gets softer with every wash. Turkish cotton is softer from day one and highly absorbent, which makes it great for post-sauna drying. Both work beautifully, so pick based on the feel you prefer. Avoid anything synthetic — polyester and microfiber trap heat, feel plasticky against sweaty skin, and do not belong in a proper sauna setup.
What to look for:
- 100% linen or 100% Turkish cotton (skip microfiber, polyester, and viscose blends)
- Large enough to sit on and wrap around your body
- Waffle weave if possible (more absorbent and dries faster)
- Dedicated sauna towels you do not mix with your bath towels
- Machine washable

My Recommendation If You Are Just Starting Out
If you are setting up your first sauna or upgrading your experience, start with these three: a wool sauna hat, a thermometer/hygrometer, and a bucket and ladle set if you have a traditional sauna. Those three will immediately improve your sessions. Everything else on this list is worth adding over time, but those three make the biggest difference per dollar spent.
More important than any accessory though: make it a habit. Consistency is where the real benefits come from — better health, more calmness, and a genuine reset from the stress of daily life. It is especially valuable for people who do intellectual work and sit at a desk all day without much physical activity, since a proper sauna session is a form of passive cardio on top of everything else. Treat it like a tool for resetting your body and mind, and you will feel the difference within weeks.
