Sauna Accessories That Change How the Bath Feels

Most sauna gear is optional. Five pieces are not — not because the room fails without them, but because each one changes what the bathing itself feels like. A bucket and ladle for the löyly (the steam thrown onto hot stones), something under your head, something behind your back, something under you, and a birch whisk. Below is how to choose each, and the one specification that decides whether it gets used for years or ends up in a cupboard.

Which accessories actually change the bath?

Piece	What it changes	The spec that decides it
Kiulu and ladle	How much steam, how often, how safely	Ladle handle at least 50 cm (20 in)
Headrest or pillow	How long lying down stays comfortable	Lifts the head 4–7 cm; untreated wood, linen, or cotton
Backrest	Whether leaning back is possible at all	Angled slats standing off the hot wall
Bench cover	Hygiene, and how hot the seat feels	Smooth-woven linen or linen-cotton, washable at 60 °C
Vasta	Scent and the feel on skin	Silver birch, about 50 cm, about 350 g

Thermometers, timers, lighting, scents, and the long list of products worth skipping sit in the full guide to sauna accessories. This page is only the short list, and only the choosing.

How do you choose a kiulu and ladle?

The kiulu — the pail that holds löyly water — is the easy half. Around five liters covers an evening in a home-sized room. Wood is traditional and handsome; a removable plastic liner or plain stainless steel survives neglect better, because heat cycles shrink staves until the seams open. Empty it after every session either way.

The ladle decides more than the bucket does. Saunologia’s ladle comparison tested throwing accuracy at 1.5, 2.3, and 3.0 meters and kept finding the same two faults. A handle shorter than roughly 50 cm puts knuckles into the steam coming back off the stones. And a deep, spherical bowl pours instead of throws — the water lands in one spot rather than spreading across the stone bed. Smaller bowls hold 2–3 dl, which suits a small room and frequent small throws; a bigger bowl earns its place in a large room, where the same result takes fewer trips. Wood stays cool in the hand, stainless does not, so check where the metal stops. How much water and how often is a separate craft, covered in throwing löyly.

What makes a headrest or backrest comfortable?

Height and width, and no synthetics anywhere. Wooden headrests run about 23–31 cm wide and lift the head 4–7 cm — enough to unkink the neck, not enough to fold it forward. Soft bench pillows are wider, roughly 39–49 cm, and let you shift position instead of committing to one. Both work; the wooden one is a permanent fixture, the linen one goes in the wash.

Materials are not a preference. Untreated wood, linen, and cotton belong in a room that runs near 90 °C at head height; polyester shells and foam fills do not, and the fire and melting risk is the reason. The same logic rules out upholstered cushions, which also hold sweat and turn sour.

A backrest is the piece most people add second and wish they had added first. Angled slats standing proud of the wall keep hot cladding off your spine and sweat off the boards, and a competent DIYer can make one from bench offcuts in an afternoon. If the room is still on paper, generous seat depth prevents the problem outright — the bench design guide has the dimensions.

What should a bench cover be made of?

Linen, cotton, or a blend, in a smooth weave. The laudeliina is the cloth you sit on, and sitting on one is the single rule every Finnish public sauna enforces — sweat soaks into bare wood and stays there. Cotton is softer, cheaper, and wrinkles less. Linen is stronger, lasts longer, and insulates better between skin and a hot seat; it also improves with washing, as the fibers soften and absorb more. A smooth weave beats terry for this job: it picks up less moisture and dirt and dries faster.

Wash at 60 °C, which is the temperature that actually deals with bacteria. Spin gently — 400 to 600 rpm — and hang the cloth straight away, smoothing it while damp. Disposable plastic sheets do the hygiene job and nothing else; a cloth you own does both.

How do you keep a vasta usable?

Cold water, never hot. The Finnish Sauna Society’s whisk guidance is unusually direct on this point: never put a whisk in hot water, and never on the stones. Between rounds, submerge the whole vasta — the birch whisk swept gently over the skin — in relatively cold water. The exception is a dried winter whisk, which needs one and a half to two hours soaking in warm water before it is supple enough to use. That is a plan, not an improvisation.

East of Lake Päijänne the word is vasta; west of it, vihta. Kotus, the Institute for the Languages of Finland, notes the boundary is blurrier than the schoolbook version — vasta is also used across central and northern Ostrobothnia, which is western dialect country.

Buy the ladle and the bench cover before the first heating; they are the two that get used every session. The headrest, backrest, and whisk can arrive in their own time, and the rest of the catalog can wait for the longer accessory list and the honest skip list. What a session looks like once the gear is in place is its own subject — start with how to use a sauna.
