Traditional Sauna Heater Stones — 20 kg Box

Enhance your sauna performance with premium-grade traditional sauna stones designed for reliable heat retention, consistent steam, and long-term durability. These natural stones are selected for thermal stability, helping your heater operate efficiently while delivering a smooth, soft löyly steam experience.

✅ Key Benefits

• Consistent Heat Output
  High thermal mass provides stable, controlled heat without spikes or drop-offs.

  Larger natural stones store heat deeply and release soft, rich steam when water is added.
• Thermal Shock Resistant
  Built to withstand repeated heating and cooling cycles without cracking quickly.
• Heater Protection
  Proper stone sizing protects heating elements and supports correct airflow inside the heater.
• Natural, Authentic Feel
  No artificial stones — just quality natural rock for a genuine sauna experience.

📏 Stone Size & Compatibility

• Mixed natural stone sizes 5 – 10 cm
• Suitable for most traditional electric sauna heaters
• One 20 kg bag is ideal for compact heaters; larger tower heaters may require 2–4 boxs

Tip: Always refer to your heater’s manual for recommended stone capacity.

🪨 Why Some Users Upgrade to Premium Stones

These natural sauna stones deliver excellent performance for everyday home use.
However, premium branded stones (like Harvia) can offer:

• More consistent stone quality and heat retention
• Longer lifespan / reduced crumbling over time
• Increased steam “softness” and heat density
• Optimized performance for high-capacity heaters

Our stones are a high-value, quality option, excellent for most users — but if you are building a luxury setup or running high heat/large heaters, premium stones may be worth considering.

⚙️ Installation Tips

• Rinse stones before placing into heater
• Load loosely to maintain airflow
• Avoid placing weight directly on heating elements
• After setup, heat and pour water over stones to remove natural first-use scent

• Short-term rentals & wellness cabins
