How Infrared Heat and Red Light Therapy Work Together in a Home Sauna
Infrared saunas and red light therapy now appear together in the same cabin, but they’re two separate systems doing two different jobs. Infrared heaters warm the air and your body directly, using panels built into the walls, bench, and back of the cabin. Because infrared warms you rather than just heating the surrounding air, these cabins run at lower temperatures than a traditional sauna, typically in the 45-65°C range rather than the 80-100°C common in conventional dry-heat saunas. That lower operating temperature is what makes infrared sessions feel more comfortable for longer stretches.
Red light therapy is a completely separate component: a dedicated panel, usually mounted on the front or side wall, that emits red and near-infrared light rather than heat. It doesn’t rely on raising the cabin temperature at all, and on both cabins in this range, you can switch it on independently of the heaters. This means a session can be heat only, light only, or both running together, whatever suits you on a given day.
What Each Cabin Actually Includes
Every model in this range is built for one to two people. It’s designed specifically for indoor use in a spare room, home gym, or dedicated wellness space with a dry, level floor and a standard household socket nearby.
Typical features across this collection include:
- Low-EMF far-infrared heating panels positioned around the cabin walls, back, and bench for even coverage
- A dedicated red light therapy panel, usable on its own or alongside the heat
- Touchscreen or app-based controls for adjusting time, temperature, and lighting
- Bluetooth audio with built-in speakers for music or podcasts during a session
- A cedar or hemlock interior, chosen for its warmth, natural aroma, and durability in a heated environment
- A standard UK 13A plug, so there’s no hardwired electrical work needed
- Straightforward two-person self-assembly, typically completed in around 20 minutes once the cartons are in the room
Cabin dimensions vary slightly by model, but you can generally expect an external footprint of roughly a metre square, with internal bench widths ranging from around 850mm up to just over a metre depending on whether the cabin is built for a cosier solo session or a more spacious two-person fit.
What Red Light Therapy Actually Is
Red light therapy uses a panel of LEDs that emit light in the red and near-infrared part of the spectrum, visually a deep red glow, quite different from the white or warm-white light in the rest of the cabin. Unlike the infrared heaters, this panel doesn’t need to warm the room or your body to function. It’s a light source, not a heat source, and it can run with the sauna completely cold if you only want a light session. Protective eyewear is typically included with these panels, since the light is more intense than standard room lighting.
What Infrared Heat Actually Does
Infrared heat works differently from the steam or dry heat you might associate with a traditional sauna. Rather than heating the air in the room first and letting that warm air heat you, infrared panels emit energy that’s absorbed directly by your skin and the tissue just beneath it, similar to the warmth you feel from sunlight on your skin on a cool day, even though the surrounding air isn’t especially hot. That’s why an infrared cabin can feel comfortably warm at 50-55°C in a way that would feel quite mild in a conventional sauna, but still produces a proper sweat over a full session.
Buying an Infrared Sauna with Red Light Therapy in the UK
Once you understand how the technology works, the practical questions matter most when choosing a unit for your home. Here’s what to check before you buy.
Power Supply and Installation
Both cabins in this category use a standard 13A plug-and-play connection, which makes installation easy for most UK homes: no electrician required and no hardwired circuit to arrange. You’ll still want a dedicated socket that isn’t shared with other high-power appliances and isn’t run through an extension lead. Larger or more powerful units elsewhere in our range may require a dedicated circuit, so always check the electrical specification of the specific model before you buy, and consult a qualified electrician wherever a hardwired connection is required.
Cabin Size and Capacity
These cabins are built for one to two people. Also, they’re designed for dry indoor rooms only, not outdoor or wet-room placement, and you’ll want a little extra clearance around the cabin for ventilation and assembly access. If you’re set on a larger, multi-person or hybrid setup instead, our hybrid sauna range combines infrared and traditional heat sources in bigger cabins built for that use case.
Authorised Dealers and Warranty
We source all units directly from authorised suppliers, and every infrared sauna we sell comes backed by a manufacturer’s warranty alongside our own Heracles support. Heracles Wellness is a 5.0-star-rated specialist retailer with over 1,000 happy customers across the UK. If you have questions about which unit suits your space, our team is available by phone, email, or live chat, and you’ll speak to a real person, not a bot.
If you’re after red light therapy on its own, without the infrared heat component, our dedicated NuviBody red light therapy beds are worth a look too. And if you’d like to compare the full spread of infrared options before deciding, browse our complete infrared sauna collection.
Frequently Asked Questions
Is red light therapy the same as infrared heat?
No. Infrared heat comes from panels built into the cabin walls and bench that warm your body directly. Red light therapy comes from a separate light panel that produces red and near-infrared light, not heat. On these cabins, you can run either one on its own or both together.
Do I need an electrician to install one of these saunas?
No. Both cabins in this category come with a standard UK 13A plug and are designed to run from a normal household socket, so no hardwired electrical installation is needed. Please make sure the socket is easily accessible, not shared with other high-power appliances, and not run through an extension lead.
Can I use the red light panel without the sauna heat turned on?
Yes. On both cabins, the red light panel operates independently from the infrared heaters, so you can run a light-only session, a heat-only session, or combine both together depending on what you want from that particular session.
How long does assembly take?
Both cabins are designed as flat-pack units with pre-installed heaters and pre-wired electrical connections. With two people, assembly typically takes around 20 minutes once the panels are in the room; no specialist tools are required beyond a basic screwdriver.
What’s the interior made from, and does it need any special care?
The cabins in this range use cedar or hemlock interiors, chosen for their natural resistance to warping in a heated environment. Wipe the interior down with a damp cloth after each session to remove perspiration, and avoid chemical or steam cleaners inside the cabin.

After many weeks researching types of sauna and customer experience, I decided on the Camilla .
Other companies doing similar to the Camilla but could not match the price from Heracles Wellness.
From making the order too delivery, communication was great. All info provided on delivery and installation.
Even help on picking electrician's.
Information on what oils and protective paint is given.
Delivery was easy and on time .
I went for Diy installation.
This was easy enough with two of us . Instructions were clear and understandable.
If any problems a quick email too Heracles Wellness was answered and solved .
I would make sure your electrician understands what is needed with installation of the heater. I had some that were not even interested in reading the manual or info provided .
How good is it?
The answer is simple ... It's Great.

Easy to use
Looks great

Totally recommend Heracles Wellness as a company .
Don't bother buying similar from Facebook when this is much more value for money.

I am very happy with the Camilla Sauna
I am very happy with the Camilla Sauna. I elected for the Sauna to be constructed by Heracles which I'd recommend as the fitters know exactly what they are doing and it's more than a normal DIY job. My elecrician found it trickey to wire in but once sorted the results are excellent. The Sauna is a good size and will fit 4 people easily. It heats up quickly and looks good. Great value against some others.

Great sauna, smooth order and installation process
Had the Camilla 3-4 person sauna installed by the Heracles team — delivered and fully assembled the same day.
Our electrician needed a bit of time to get to grips with the wiring, but Abdul from customer support helped talk him through it. Abdul was helpful throughout, always quick to respond to questions.
Heats up quickly in the current weather, though we haven't tried it in winter yet so can't speak to performance in colder conditions.
Very happy to recommend Heracles.

From my initial enquiry to installation Keith from Heracles has been very helpful. The whole buying journey was smooth and customer focused. The installation team were on time and cleaned up after installing the sauna. The sauna itself is great quality and looks even better than the website photos. Highly recommend this product

Great sauna but more importantly great service
Summary: A great sauna and more importantly a very good experience buying, installing and minor issue resolution.
I bought this sauna for a holiday let I own in the Lake District. Keith and the team talked me through the options particularly as this is quite an exposed location. Unlike the other companies I spoke to, they were very upfront about the work needed and costs to install above the unit purchase price.
Unit bought and arranged a few weeks ahead when I didnt have guests and I would be in the area and on hand. Team and pack arrived at the right time and installed without issue. The electrician then attended the following day from a list of recommendations who also did a straight forward ontime on price good job.
A couple of months on there was a minor issue with the door and teh huum controller, both sorted very quickly and not noticed by the holiday guests
I am sure you can buy a cheaper sauna but in this case I have no issues during and after the installation. Will use again when I need more equipment like this in future

Exceptional ice bath!
This is a very high quality product, backed by exceptional service from all members of the team.
The ice bath is beautifully constructed and feels really to use The seat is deep enough to get water over the shoulders and you can fully submerge as needed.
The chiller is easy to use on the app, gets the water cold quickly and maintains a clean and cold bath ready to use any time.
Pairs beautifully with the sauna, thank you Keith, Pawel and the rest of the team!

Brilliant and spacious sauna
We're super happy with the Leil Patio sauna. Not only it looks great it seems extremely well built. Keith's team did a great job assembling it and we're looking forward to many sauna sessions.
The changing rooms is a lot more spacious than it seems in the photos and definitely a plus for a break without having to go outside.

Löyly in Lancashire!
I recently received the Camilla sauna from Heracles Wellness, and the entire experience, from initial enquiry through to installation and daily use has been absolutely first-class.
A massive thank you to Keith and the wider sales team. Keith was fantastic to deal with: knowledgeable, patient, and completely transparent throughout the process. Keith answered all my questions with genuine expertise and made sure I chose the exact setup suited to my space and needs.
The assembly team deserves equal praise. They arrived promptly, worked cleanly and efficiently, and paid meticulous attention to detail during the build. They treated our property with total respect and took the time to walk us through the controls and maintenance before leaving.
As for the Camilla sauna itself, it has exceeded all expectations!
Stunning Design: It looks gorgeous—the craftsmanship, wood finish, and overall aesthetics make it a real focal point.
Flawless (and easy) operation: It heats up quickly, maintains consistent temperature effortlessly, and delivers an incredible sauna experience every single session. I'm generally having 2-3 sessions as week at ~90deg for 20mins.
If you are considering investing in a high-quality sauna and want seamless customer service from people who genuinely care about what they do, look no further than these guys. I cannot recommend Keith and the entire HW team highly enough!

Absolutely delighted with the modus sauna
Absolutely delighted with the modus sauna. Very high quality product. I would highly recommend this model as the kit is high spec, I put it together with my dad who is a tradesman. If you build this yourself I would recommend getting someone who is experienced in tools/building. We got an electrician to install all the heater. Couldn’t fault the customer service with the Heracles and Wellness team who kept me updated with the delivery of sauna and any queries I had. A special mention to Abdullah who has been really efficient. If buying a sauna would highly recommend Heracles and Wellness.

First class service and highly competitive pricing
First class service and highly competitive pricing.
The whole process went really well.
We had an issue with the lifter supplied and so it was returned and a timely refund issued.
The delivery team from Trinity spa's were first class too. All highly professional.
Remember the tub comes without a flex and plug so we purchased from Screwfix Flexi cable 10m coil 3 core 1.5mm and a plug ! Easy installation.
If you purchase a rear mounted lifter, I suggest you add a additional piece of 3" x 2" to attach to the main frame to help support the lifter.
I am running the tub on eco3spa chlorine free products. Water remains crystal clear and odourless.
All in all a great investment and a lot of fun too.

So pleased with our Camille cube sauna
Really pleased with my Camille cube sauna. I did lots of research before purchasing and Heracles came out top. Evem our beach sauna guy sang their praises. Keith and team were great, moving delivery date when I wasn't ready and with lots of advice during our build. Though I had my own joiner I would recommend using their installation team as they have the expertise. We are so happy with the purchase and look forward to enjoying the benefits for many years to come.

Honest Review…..and its Big Yes from me
The only way to truly rate a product is by considering the whole process start to finish and I will say with all honesty, that I found the information before hand and the purchasing process very satisfying. It certainly helped that the web page was extremely thorough so there was no doubt about what you were receiving.
The delivery was seamless on a date of my choice, and the team of fitters who turned up shortly afterwards, were very polite and friendly. I had concerns over freshly laid grass but I need not have worried. They laid a ground sheet and worked precisely and efficiently to a finish about 4hrs later. Although they left the waste, it was left tidily and made disposing of it a simple task. A real pleasure to deal with tradesmen who clearly enjoyed their work and did it with an old fashioned ethic.
I’ve since treated the outside of the sauna but not the inside so I’m yet to use it but it blends wonderfully in with my garden.
On a final note, I reviewed and researched garden saunas for a long time before deciding that Herecles ticked all my boxes. The materials used plus the extras made it stand out from the crowd and I can honestly say that the reality certainly matched the hype.

New Garden Sauna
Our Camilla 3-4 person suana does exactly as stated on the box. It heats up quickly and you can get in after about 20 min although 30 allows it to reach the temperature we like. I built it myself and found that it went together relatively easily. You have to be a bit careful with the thermowood as it is very brittle and when interlocking the ends can sometimes split away but this is not a real issue if you are careful with it.
I had my local electrician wire up the heater and again that was a relatively simple job.
We have only had two people in it to date but more than enough room for 3 or 4.
Bought a cheap and cheerful cold water plunge pool and works well with the sauna.
Overall very pleased and would recommend one if you are looking at a simple set up for your garden.

Superb in every way!
They say ‘happy wife, happy life’. Well I can vouch for that, we are both extremely happy with our latest addition to home set-up.
From the beginning the sauna was easy to purchase and get delivered (with in a couple of weeks due to stock levels). I had to hand ball off the lorry as the pallet it comes in was too big for the tail lift but that’s about the most difficult part of the whole process.
Instructions were fairly straightforward though I am a builder so have experience in this sort of thing. But most handy DIYers will find this easy enough to build.
If you plan in the time to paint various woods at different stages of the build it will help. i.e paint interior wall and benches prior to fitting the benches makes its easier to reach those otherwise hard to reach places.
The guys sent a really great link with electrical details needed for your electrician so you can prep ahead of time and get materials in place for their arrival. Think it took my guy about three hours to hook it up.
Quality of the thermo wood is excellent keeps the heat in really well. The Heater is easy to operate and within 20mins it’s ready to jump in. Max heat will in time reach 90+degrees which is too hot for me.
Already have friends and family asking about it.

Amazing product, exceptional service
The quality of the black cube sauna really is top notch, from the roof shingles to the heater every component is quality.
Delivery was perfect, on time and professional. The driver contacted me on route with an ETA and went out of his way to help me get the large pallet into my garage.
I chose to build the sauna myself which was relatively straightforward and quite enjoyable. The construction guide was comprehensive and easy to follow.
We use our new sausa almost every day and couldn't be happier.
Would certainly recommend Heracles and the black cube to anyone considering an outdoor sauna.
