Infrared precision. Traditional power. Built for Australian outdoors.
The Innerlight Demfin 6 Person Hybrid Outdoor Sauna combines the immersive heat of a traditional sauna with the targeted warmth of infrared technology in one premium outdoor unit. Designed specifically for Australian conditions, it features a fully weatherproof aluminium exterior, premium Western Red Cedar interior, and a spacious layout that comfortably accommodates up to six people.
Whether you prefer a high-heat traditional sauna session, gentle infrared warmth, or a combination of both, the Demfin 6 gives you the flexibility to customise your wellness experience. Built for durability, comfort, and long-term performance, it's a sauna designed to become a permanent feature of your outdoor space.
How does the Innerlight Demfin 6 Person Hybrid Outdoor Sauna achieve this?
The Demfin 6 combines three heating technologies within a single sauna system. A Harvia 6kW traditional hot-stone heater delivers authentic high-temperature sauna sessions, while full-wall mica infrared panels provide fast, even heat distribution. Full-spectrum front heaters deliver near, mid, and far infrared wavelengths for targeted warmth.
This hybrid design allows users to choose the sauna experience that best suits their preferences, from short recovery sessions to longer relaxation rituals. Integrated WiFi controls allow you to preheat and manage sessions remotely for added convenience.

Frequently Asked Questions:
Q: Are the outdoor saunas weatherproof?
A: Yes. The Demfin 6 Hybrid is fully weather-sealed with an aluminium exterior, tempered safety glass, and sealed joints designed to withstand rain, heat, humidity, and changing outdoor conditions.
Q: Do I need a cover for the sauna?
A: No. The Demfin 6 Hybrid is designed for permanent outdoor installation without a cover. Optional covers are available for additional protection if desired.
Q: Can this sauna be installed indoors?
A: Yes. Although designed for outdoor use, the Demfin 6 Hybrid can also be installed indoors provided there is sufficient space and suitable electrical access.
Q: What surface should the sauna sit on?
A: The sauna should be installed on a hard, level surface such as concrete, pavers, or decking with adequate drainage underneath.
Q: How long does it take to heat up?
A: Heat-up time varies depending on ambient conditions, but approximately 30 minutes is a good guide before use.
Q: What power is required?
A: The Demfin 6 Hybrid requires hardwired 25A electrical connections and installation by a licensed electrician. Separate connections are provided for the traditional heater and infrared system.
Q: Are your saunas low EMF?
A: Yes. Innerlight states that its sauna range has been tested between 0–1mG to minimise EMF exposure.
Q: How do I clean the sauna?
A: Wipe interior surfaces with a damp cloth after use. The cedar can be lightly sanded if required over time. The exterior aluminium surfaces and glass can be cleaned using a damp microfibre cloth.
Q. What's not covered in warranty?
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.
Electrician’s Note:
The power connection point is located at the top rear centre of the sauna, so ensure cable access is prepared before installation.
