Transform any compact outdoor space into a wellness sanctuary with the Innerlight 3 Person Demfin Outdoor Traditional Sauna. Built with sleek black aluminium exterior panelling and lined with rich Western Red Cedar, this sauna blends modern outdoor durability with authentic Finnish sauna tradition.
Powered by a premium Harvia 4.5kW hot-stone heater, the Demfin delivers the deep, restorative heat traditional sauna bathing is known for. Whether you're unwinding after a long day, recovering from a workout, or starting your morning with clarity and focus, the Demfin creates a calm retreat right in your own backyard.
Perfect for couples, small families, or solo relaxation, it delivers a full traditional sauna experience in a compact, beautifully designed footprint.
The Demfin combines authentic Finnish sauna heating with premium materials designed for outdoor longevity.
At its core is a Harvia 4.5kW traditional hot-stone heater, allowing you to experience both dry heat or steam sauna sessions by simply pouring water over the stones to adjust humidity levels.
Inside, the natural Western Red Cedar interior radiates warmth and releases a subtle aromatic scent, enhancing relaxation and creating a classic sauna environment. The explosion-proof LED ceiling light and soft headrest strip lighting gently illuminate the cedar interior, creating a calm and restorative atmosphere.
With a compact square footprint and single-row bench design, the Demfin comfortably accommodates two to three people while remaining ideal for smaller outdoor spaces such as patios, courtyards, home gyms, or townhouse backyards.
A: The sauna assembly requires at least 2–4 people and typically takes around an hour. You will need a rubber mallet to tap the wall panels into place. If the sauna will be exposed to rain, black or clear silicone is recommended to seal the edges and keep water out.
A: The sauna should be installed on a flat, solid surface such as concrete, decking, tiles, or pavers to ensure stability and proper installation.
A: The sauna uses up to 4500 W and must be hardwired by a licensed electrician.
A: While the sauna is designed for outdoor use, purchasing an additional cover is recommended to protect it from long-term exposure to the elements and extend its lifespan.
A. The Demfin 3 Traditional Sauna operates at a maximum output of 4500 W and requires a dedicated 20 Amp single-phase power point.
This sauna must be connected by a licensed electrician to ensure proper wiring, circuit protection, and compliance with Australian electrical standards. A safety switch and dedicated circuit are strongly recommended for stable, long-term performance.
For best results, install the sauna on a hard, flat, level surface such as concrete, decking, or tiles with sufficient ventilation and clearance around the unit.
Electrician's Note:
The power connection point is located at the top rear centre of the sauna. Please ensure cable access is available before installation.
A. Silicone Maintenance (Outdoor Models): Owners are responsible for maintaining external silicone seals around windows and doors.
It is the customer’s responsibility to check the integrity of the silicone every 12–18 months and reapply outdoor-grade silicone if required.
Failure to maintain these seals may lead to water ingress, which is not covered under warranty.
Water Damage & Drainage: Damage caused by standing water, flooding, poor site drainage, or blocked drains is not covered.
All saunas must be installed on a hard, level, well-drained surface to avoid water ingress or pooling underneath.
The sauna floor and base are designed to handle normal humidity and light splashing but are not waterproof.
Any damage caused by flooding, inadequate drainage, or improper installation is considered site-related and not a manufacturing defect.
General Wear & Tear: Natural aging, fading, or weathering of timber and finishes caused by exposure to sunlight, humidity, or temperature variations.
Misuse or Neglect: Damage resulting from improper installation, electrical overloading, water exposure, or failure to follow care instructions.
Accidental Damage: Cracked glass, dents, or impact damage from misuse.
Unauthorised Repairs or Modifications: Any work or alteration carried out by non-approved technicians will void the warranty.
Installation options available in some areas. Contact us for further information.
Note: The sauna is recommended to be covered when not in use.
