Sauna Accessory Guide
Last Updated: April 2026
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 sauna 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 — olivine diabase, peridotite, and vulcanite are common types. Never use river rocks or decorative stones.
- 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.
- Replacement: Inspect annually and replace 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: 16–20 inches is ideal to keep your hand away from the heat.
- Bucket capacity: 1–2 liters is standard.
- Infusions: Add a few drops of sauna essential oil (eucalyptus, birch, pine) to the water for an aromatic löyly experience.
Thermometers & Hygrometers
- Thermometer: Mount on the upper wall near the ceiling. Look for a wood-framed sauna thermometer rated to at least 250°F.
- Hygrometer: Measures humidity — useful for monitoring steam levels in traditional saunas.
- Combo units: Many sauna thermometer/hygrometer combos are available in a single unit.
Backrests & Headrests
- 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.
Sauna Lighting
- Sauna-rated fixtures only: Standard electrical fixtures cannot handle sauna heat and humidity.
- LED sauna lights: Low-heat, energy-efficient, available in warm tones.
- Fiber optic lighting: A premium option — 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.
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.
- Bench covers (pre-cut towels sized to fit your bench) are a convenient option.
Sand Timers & Hourglasses
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
- 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.
- 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.
