Accessory lists for saunas tend to be padded. Somewhere between the bucket and the birch whisk, they stop describing things you will use weekly and start describing things that sit in a corner gathering dust. This checklist is the shorter version: what genuinely earns its place in a home sauna, what changes how often you actually use the room, and what you can skip until later.
The order matters. Everything in the first section is worth buying before your first session. Everything after that can wait until you know how you use the sauna.
The Non-Negotiables
A bucket and ladle
Pouring water over hot stones — löyly — is the difference between sitting in a hot box and taking a sauna. Steam raises perceived heat sharply, softens the air, and makes higher temperatures comfortable rather than harsh. Without a bucket, a traditional sauna is only doing half its job.
Buy an aluminium or lined wooden bucket in the one-gallon range with a long ladle. A gallon is roughly one session's worth for two people; smaller buckets mean getting up to refill.
A thermometer and a hygrometer
These two dials do more than satisfy curiosity. Temperature tells you when the room is ready — most traditional saunas settle between 160°F and 195°F. Humidity tells you whether you are over-pouring. Above roughly 30% relative humidity at high heat, the air starts to feel scalding rather than enveloping, and that is the point at which people cut sessions short without knowing why.
SaunaLife Accessory Package 5 — Bucket, Ladle, Hygrometer & Thermometer
The four essentials in a single order, which is the cheapest and least annoying way to buy them. The bucket is made in Finland from lightweight aluminium — it will not warp, leak, or grow mould the way untreated wooden buckets eventually do — and comes paired with a bamboo ladle plus matching round gauges for temperature and humidity.
A timer
Not for discipline — for safety. Heat blunts your sense of elapsed time, and the standard guidance of 15 to 20 minutes per round is easy to overshoot when you are relaxed and slightly dehydrated. A sand timer or a wall clock rated for sauna temperatures solves it. Phones do not belong in a 190°F room.
The Comfort Layer
A headrest
The cheapest upgrade that changes how long you can comfortably stay in. Lying flat on a bench with your head unsupported puts your neck at an angle you will notice within ten minutes. Alder is the traditional choice because it stays remarkably cool to the touch even at full sauna temperature.
SaunaLife SaunaGear Headrest 1 — Wooden Alder with Cloth Neck Support
Alder wood is prized in sauna interiors precisely because it refuses to get uncomfortably hot, and this headrest pairs it with a cloth neck support so the contact point is soft rather than bare timber. It sits on the bench rather than mounting to the wall, so it works in a barrel, a cabin, or an indoor cabin sauna without modification.
Bench cushions and backrests
Worth it if your benches are cedar or if anyone in the household finds bare wood at 180°F uncomfortable on bare skin. Stain-resistant fabric pads solve the problem without the hygiene issues of towels that never quite dry. The ProSaunas comfort seat pads fit most standard bench widths.
A sauna hat
It looks eccentric and it is entirely practical. Wool or felt insulates your scalp, keeps your head cooler than the surrounding air, and lets you stay in longer without the light-headedness that ends most sessions early. The same principle applies in reverse for cold water — a LUUN Kall cold plunge hat does the equivalent job during ice baths. Browse the full LUUN wool and felt headwear range if you want both.
Maintenance: The Part Everyone Skips
Sauna wood absorbs sweat, water, and body oils. Untreated benches darken and stain within a season of regular use, and the fix is far cheaper than the eventual replacement.
SaunaLife Sauna Wax — Natural Sauna Wood Wax, 15.2oz
A natural wax formulated for interior sauna surfaces. It absorbs into the timber rather than sitting on top of it, creating a water-resistant layer that stops sweat and moisture soaking into benches, backrests, and walls. One tin covers a typical home sauna interior, and an annual reapplication keeps the wood looking close to new.
Alongside wax, keep a dedicated sauna cleaner on hand. Household disinfectants leave residues that vaporise unpleasantly at high heat; sauna-specific cleaners are formulated not to. And for exterior wood on an outdoor cabin or barrel, an odourless sauna paraffin oil does the same protective job without adding scent to the room.
Worth Adding Later
- Lighting. Indirect LED behind the backrests changes the atmosphere completely. Fixtures must be rated for sauna heat and humidity — standard LED strip will fail fast.
- Extra sauna stones. Stones degrade. Crumbling or cracked stones restrict airflow through the heater and shorten element life. Replace them every few years.
- A floor mat or duckboard. Protects the floor and stops the slipperiness that develops on wet wood.
- A birch whisk (vihta). Traditional, pleasant, entirely optional.
- A cold plunge or cold shower. Not an accessory so much as the other half of the ritual, and the single biggest upgrade to how you feel afterwards.
What You Can Skip
Essential oils poured directly onto stones — they scorch, smell acrid, and can damage the heater. Use a diffuser cup or add a few drops to the water bucket instead. Bluetooth speakers built into buckets are fun but rarely used twice. And elaborate multi-piece gift sets usually duplicate what a four-piece package already gave you.
Frequently Asked Questions
What accessories do I need before my first sauna session?
A bucket and ladle, a thermometer, a hygrometer, and a timer. Everything else can wait.
Can I use a regular bucket in a sauna?
Not reliably. Plastic buckets can deform or off-gas at sauna temperatures, and metal handles get hot enough to burn. Purpose-built sauna buckets use heat-safe materials and insulated handles.
How often should I treat sauna wood?
Interior surfaces roughly once a year with regular use, or whenever water stops beading on the bench. Exterior wood on outdoor models generally needs attention annually, more often in harsh climates.
Are sauna hats actually necessary?
Not necessary, but genuinely useful. They keep your head cooler than the ambient air, which for most people means a longer, more comfortable session.
Do infrared saunas need the same accessories?
No. Infrared cabins run at lower temperatures and have no stones, so the bucket, ladle, and hygrometer are irrelevant. A towel, a timer, and a cushion cover the essentials.
The Bottom Line
Four items make a sauna work properly: bucket, ladle, thermometer, hygrometer. One item makes it comfortable enough that you use it more often: a headrest. One item makes it last: wood wax. That is the entire honest checklist, and buying the first four as a bundle is cheaper than assembling them one at a time.
Everything beyond that is refinement rather than requirement. Explore the SaunaLife range of components and extras or the wood care and cleaner range when you know how you actually use your sauna — that is a much better guide than any list, including this one.
