Product Description

The Demfin 3 Traditional Sauna captures the essence of authentic sauna bathing in a sleek, compact design.

Built from rich Western Red Cedar and finished with modern black aluminium panelling, it’s crafted for both beauty and endurance. Inside, the Harvia 4.5 kW hot-stone stove fills the air with dry, gentle heat that soothes the body and clears the mind.

The glow from the explosion-proof LED lighting bounces softly off the cedar walls, creating a calm, restorative atmosphere that feels like your own private retreat 🍃.

Designed for up to three people, the Demfin 3 features a single-row bench that’s perfect for stretching out solo or relaxing side by side. It delivers all the benefits of a full-size sauna in a refined, space-efficient form — ideal for smaller outdoor areas or home gyms. With its premium materials, timeless design, and effortless performance, the Demfin 3 turns everyday recovery into something extraordinary ✨.

Power Requirements

⚡ Power & Installation Requirements

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 power 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, and 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.

Whether it’s to unwind after a workout or recharge at the end of a long day, the Demfin 3 offers a simple, powerful way to restore balance and clarity ✨.

What’s the difference between infrared and traditional saunas?

Traditional saunas heat the air around you; Infrared saunas heat your body directly. That means they run at a lower temperature but deliver a deeper, more comfortable sweat. You’ll feel the benefits faster and can stay in longer without feeling overwhelmed.

We offer both options and have no bias so the choice is yours.

How do I clean the sauna?

Use a soft cloth with water or natural cleaner.

The best way keep your sauna as new is to give the sweaty surfaces a wipe down with a damp cloth or towel after each session. If you miss the wipe down after your session, the next day is fine. Just try jot to let the sweat stains build up.
If it does start to get a bit yellow, you can give the timber s light sand down. That will always bring it back to new condition.
To clean the outside of the sauna you can use a damp microfibre cloth for the aluminium frame as well as on the glass doors and windows too.

The sauna should always sit on a hard level surface.

You can start receiving the benefits of infrared at any temperature above 45 degrees, however if you enter the sauna when the sauna is hotter, you'll begin to sweat faster.

Wooden Sauna Back Rest
Shane Hegarty
Wooden Sauna back rests

I do like the wooden sauna back rests, the curve fits your back well, i thought they possibly could have non slip rubber footings & include a coat of natural oil on the timber…

Good product.

The stand for the panel is great for relocating and repositioning .
We have been enjoying improved sleep patterns by using the panel of an evening before bedtime and assistance with back and knee injuries.
Hopefully there will also be long-term benefits.

A nightly ritual for healing, skin & sleep

I originally purchased the A300 panel to support my surgery recovery, but it’s become so much more than that. I now use it most nights before applying my skincare, and I’ve noticed how much better my serums absorb afterward. Since learning it’s medical grade, I also feel reassured knowing it’s supporting both recovery and long-term beauty benefits like skin tightening. What surprised me most is the impact on my sleep. My sleep cycle app consistently shows deeper, better-quality rest on the nights I use the panel. It’s turned into a ritual I look forward to – combining red light therapy with a facial routine has become my favourite form of self-care.
Self-care is essential for quality of life, and this panel has elevated mine. Highly recommend.

Love my new sauna

I have been wanting a sauna for ever and finally got enough space outside for one - I had been researching a number of saunas before settling on this one - mainly the aesthetic look tipped me to Inner Light. I absolutely love the sauna… it’s my favourite purchase. The only slight feedback I would have is the quality of the finish on the outside - for example the silicone has a rushed messy finished but thats nitpicking.

Quality Outdoor Sauna

I absolutely love my outdoor sauna. It heats fast and is big enough to lay down in. I need to mention the customer service. It’s 10/10 and the best I have experienced in years which is so refreshing.

Sparkles

Nearly 2 months post installation, sauna has exceeded expectations.
It generates more heat and quicker than my prior experience of infrareds. Even though this is an outdoor one. Our adult kids also all enjoy. Totally genuine and we are very happy.

To be frank, I was worried initially that this could have been a scam, despite a bit of phone contact, particularly after the first payment. But all good! Totally genuine and we are very happy.

Happy wife happy life

Very happy from time of sale , after sales follow through to installation. Good quality and sauna exactly what you expect.
The two installers I had in Darsey and James were fantastic, great customer service and they know what they are doing, had the 5 person unit installed in around an hour. Again I think you can’t fault these guys.

Installation was done quickly and efficiently. The installers were polite and kept the mess to a minimum including final clean up.

Feeling Amazing

We are so impressed with our 2 person outdoor infrared sauna and could not be happier. The overall feeling when you get out is just amazing, it’s hard to explain. Our skin is feeling better and overall health and wellbeing has improved. We use it if not every day, every second and having it in our backyard is incredible. It looks so beautiful too and makes our courtyard like a private health spa. Mark and Chloe were wonderful to deal with and we couldn’t be happier with our choice of Innerlight.

We have just purchased the Bella deluxe outdoor sauna. Very glad we purchased the 5 person to comfortably fit 3 people. The app is great and sauna is ready for when we get home. We put it together ourselves with 4 people assisting. The customer service was exceptional and answered all my questions before purchasing and after.
Very happy customers so far.
