Harvia Olivine Diabase Sauna Stones R-991 — 4 Boxes Included
The quality of your sauna stones directly impacts the quality of your löyly. That's why the Ultimate Package includes 4 boxes of Harvia's premium Olivine Diabase Rounded Stones R-991 — the exact stone specification required by the Spirit SP90E heater.
Olivine Diabase is one of the most thermally stable volcanic rock types available, delivering:
- 🪨 Superior heat retention — absorbs and releases heat slowly and evenly for a smooth, soft sauna experience
- 💧 Excellent steam generation — produces a generous, long-lasting löyly when water is poured over the stones
- 🔁 Long lifespan — highly crack- and fracture-resistant compared to standard sauna stones
- 📐 Optimal size — Ø 5–10 cm (2"–4"), perfectly sized for the Spirit's stone basket
- ✅ Harvia-recommended — sourced and tested to the Spirit SP90E's exact capacity (110 lbs / 49.9 kg)
With all 4 boxes included, your heater arrives ready to be loaded and fired up — no additional stone orders needed.
Harvia Spirit Safety Railing — Included
Safety is a non-negotiable part of every great sauna. The Harvia Spirit Safety Railing is a purpose-built protective guard designed specifically for the Spirit SP90E heater. It creates a clear, defined safety perimeter around the heater, preventing accidental contact with the hot surfaces of both the unit and the stones during a session.
