HealthHQ Axion Wood Fire Sauna Heater Stove

Outdoor Wood-Fired Sauna Stove with Stone Cage

There's something elemental about wood-fired heat. The HealthHQ Outdoor Wood-Fired Sauna Stove is built around that ritual — an exposed cage of glowing sauna stones, a live fire burning behind glass, and a wave of deep radiant heat that no electric heater can replicate. Designed for permanent outdoor sauna installation and delivering up to 18 kW, this 304 stainless steel powerhouse is engineered to handle New Zealand's outdoor conditions year-round and keep performing season after season.

Features

• Exposed Stone Cage — Raw Heat, Full Radiation
  The open cage basket is the centrepiece of the design — fully loaded with sauna stones and fully exposed to the room. Stones absorb and radiate heat in every direction, delivering the deep, enveloping warmth that defines a true wood-fired sauna experience.
• Outdoor-Grade 304 Stainless Steel Body
  Built for permanent outdoor installation. Corrosion-resistant, moisture-resistant, and built to hold its form through temperature extremes — no rust, no maintenance headaches, no compromises.
• Glass Viewing Door — The Fire Is Part of the Experience
  Watch the flames work through the glass door. Functional, yes — but more than that, it's atmospheric. The visual warmth of a live fire adds a dimension no digital display can match.
• Internal Chimney Configuration — Clean Install, No Exterior Pipe
  The chimney routes internally through the cabin roof, keeping the exterior clean and the installation seamless. Includes a waterproof outdoor cover for a fully weather-tight finish.
• Universal Stone Compatibility
  Works with any sauna stones — Olivine Diabase recommended for optimal heat retention and longevity. You'll need approximately 4–5 boxes to fill the cage properly (stones not included).
