Sauna Accessories Guide
The right accessories transform a good sauna session into a great one. Whether you're setting up a new sauna or upgrading an existing one, this guide covers the essential and premium accessories worth considering.
Sauna Stones
Sauna stones are one of the most important accessories for any electric or wood-burning sauna. They absorb heat from the heater and release it slowly, creating a stable, comfortable heat environment. Pouring water over hot stones creates löyly — the burst of steam that defines the traditional Finnish sauna experience.
What to look for:
-
Stone type: Use only stones specifically rated for sauna use. Common types include olivine diabase, peridotite, and vulcanite. Never use river rocks or decorative stones — they can crack or explode under heat.
-
Size: Most heaters specify a stone size range (typically 2–4 inches or 5–10 cm). Match the stone size to your heater's requirements.
-
Quantity: Your heater's manual will specify how many pounds of stones are required. Do not under-fill — it reduces heat retention and can damage the heater.
-
Replacement: Sauna stones should be inspected annually and replaced every 3–5 years, or sooner if they begin to crack or crumble.
Ladles & Water Buckets
A ladle and bucket set is essential for pouring water over the stones to create löyly. Look for:
-
Material: Cedar, aspen, or stainless steel. Avoid plastic — it degrades in the heat.
-
Ladle length: Longer handles keep your hand away from the heat. 16–20 inches is ideal.
-
Bucket capacity: 1–2 liters is standard for a personal sauna bucket.
-
Infusions: Add a few drops of sauna essential oil (eucalyptus, birch, pine) to the water for an aromatic löyly experience.
Thermometers & Hygrometers
Knowing the temperature and humidity in your sauna helps you optimize your session and protect your equipment.
-
Thermometer: Mount on the upper wall near the ceiling where temperatures are highest. Look for a wood-framed sauna thermometer rated to at least 250°F.
-
Hygrometer: Measures humidity. Useful for traditional saunas where you want to monitor how much steam you're generating with löyly.
-
Combo units: Many sauna thermometer/hygrometer combos are available in a single unit — a convenient option.
Backrests & Headrests
Comfort accessories make longer sessions more enjoyable:
-
Backrests: Ergonomic wood backrests that hook over the bench allow you to lean back comfortably without touching the hot wall.
-
Headrests/pillows: Wood or rolled towel headrests support your neck when lying down on the bench.
-
Bench cushions: Removable, washable cushions add comfort for longer sessions. Look for materials rated for sauna temperatures.
Sauna Lighting
Lighting sets the mood and is a safety consideration:
-
Sauna-rated fixtures only: Standard electrical fixtures cannot handle sauna heat and humidity. Use only fixtures specifically rated for sauna environments.
-
LED sauna lights: Low-heat, energy-efficient, and available in warm tones that create a relaxing ambiance.
-
Fiber optic lighting: A premium option that creates a starfield effect on the ceiling — the light source stays outside the sauna, so there's no heat concern.
-
Placement: Mount lights low on the walls or under benches — never directly overhead where heat is most intense.
Sauna Towels & Seat Covers
- Always sit or lie on a towel in the sauna — it absorbs sweat and protects the wood benches.
- Look for 100% cotton or linen sauna towels — they absorb well and withstand repeated high-heat washing.
-
Bench covers (pre-cut towels sized to fit your bench) are a convenient option for keeping benches clean.
Sand Timers & Hourglasses
A classic sauna accessory — a wood-framed sand timer (typically 5, 10, or 15 minutes) lets you track your session without bringing a phone into the sauna. Simple, reliable, and heat-safe.
Essential Oils & Sauna Aromas
Adding a few drops of sauna-safe essential oil to your löyly water elevates the experience:
-
Eucalyptus — opens airways, refreshing and invigorating
-
Birch — traditional Finnish aroma, earthy and clean
-
Pine — forest-fresh, grounding
-
Peppermint — cooling sensation, great post-workout
Important: Use only food-grade or sauna-specific essential oils. Never apply undiluted oils directly to stones.
Maintenance Accessories
-
Sauna cleaner: Use a pH-neutral, sauna-safe cleaner for benches and walls. Avoid harsh chemicals that can damage wood or leave residue.
-
Brush: A soft-bristle brush helps scrub benches without scratching the wood.
-
Ventilation: Always leave the sauna door and vents open after use to dry it out completely and prevent mold.
