How to Choose the Right Traditional Outdoor Sauna for Your Garden
The most common difficulty buyers face is deciding which specifications are right for your garden, household, and budget. Cabin size, heater power, timber quality, and electrical supply requirements all matter, but there’s no way to confirm them from the product listing alone. The sections below cover the key decision points so you can make informed decisions.
Cabin Size and Bather Capacity
Manufacturer capacity figures reflect the maximum number of people who can physically fit inside a sauna. As a practical rule, a cabin described as seating four works well for two to three adults bathing at a relaxed pace, with adequate bench space and air circulation. The Camilla Traditional Outdoor Sauna is a good example at this level. It’s rated for three to four bathers, and offers a well-proportioned interior without requiring a large garden footprint.
If you have families or households, step up to a five- or six-person cabin.
Heater Type and kW Rating
Traditional Finnish saunas use either a wood-burning stove or an electric heater to generate the heat and steam that defines the bathing experience. Wood-fired heaters produce a deep, radiant heat and require no dedicated electrical connection, which makes them practical for gardens where running a cable is difficult. Electric heaters, on the other hand, offer precise temperature control, faster heat-up times, and the option to preheat the cabin remotely via a control unit or app.
As a general guide, allow approximately 1 kW of heater output per cubic metre of sauna room volume. Always consult a qualified electrician before installing any hardwired electrical equipment, in accordance with UK BS 7671 wiring regulations.
Timber Grade and Weather Resistance
For a sauna that will spend its life in a UK garden, the timber specification matters as much as the heater choice. Thermowood, heat-treated timber modified at high temperatures to improve dimensional stability and resistance to moisture, is the material of choice for outdoor sauna cabins exposed to British rain and temperature variation. Nordic spruce and Canadian red cedar are also widely used for interior bench and lining work, offering natural heat resistance and a pleasant aromatic quality during bathing.
Warranty and After-Sales Support
A traditional outdoor sauna is a long-term purchase, and the quality of after-sales support matters more than it does for lower-value products. Heracles Wellness includes manufacturer warranties on every sauna sold, and our team provides ongoing support from initial enquiry through to delivery, installation, and beyond.
What to Look for When Buying a Traditional Outdoor Sauna in the UK
Once you move past the aesthetics and start comparing specifications, the differences between models become meaningful. Room volume, timber grade, heater compatibility, and how a sauna handles sustained exposure to British weather are the details that separate a product you will enjoy for a decade from one that disappoints within the first winter. Here are the factors to consider before you commit.
Timber Quality and Weather Resistance
Not all outdoor sauna timber performs equally in the UK climate. Heat-treated thermowood, kiln-dried Nordic spruce, and Canadian red cedar are the materials worth looking for. Thermowood in particular undergoes a high-temperature thermal modification process that makes it dimensionally stable, resistant to moisture absorption, and far less prone to warping or cracking under repeated wet-to-dry cycles.
If a product listing does not specify the timber treatment process, that is worth querying before purchase. At Heracles Wellness, every outdoor sauna we stock comes with clear material specifications so you know exactly what you are installing in your garden.
Price Tiers and What to Expect
Traditional outdoor sauna pricing costs around £3,800 to £4,000 for a two-person cabin with a shingled or metal roof, standard bench configuration, and solid timber construction. This makes it a practical choice for smaller gardens and buyers who want a functional sauna without committing to a larger build.
Mid-range cabins, priced from around £4,000 to £9,000, tend to offer more interior volume, higher-grade thermowood cladding, integrated heater packages, and accessories such as lighting, thermometers, and ladles included as standard. At this tier, the quality of joinery and wall panel thickness becomes noticeably better, and the sauna will handle year-round outdoor use more reliably.
Above £9,000, buyers can expect premium timber grades, larger footprints suitable for four or more bathers, and often the option of a wood-fired or combination heater setup. If you are unsure which specification suits your garden dimensions and usage plans, our team is available by phone, email, or live chat to help you work through the options before you buy.
Frequently Asked Questions
How long will a traditional outdoor sauna last?
A well-built outdoor sauna in thermowood or Canadian red cedar, properly sited and maintained, will comfortably last fifteen to twenty years in the British climate. Thermowood’s thermal modification process makes it dimensionally stable and resistant to moisture, so the freeze-thaw cycles of a UK winter present no real problem. Annual treatment of external timber surfaces is the main maintenance task to keep the cabin looking its best.
What warranty comes with a traditional outdoor sauna?
Warranty terms vary by manufacturer, so it is worth checking before you buy. At Heracles Wellness, every sauna we sell carries the full manufacturer’s warranty, and our team remains available by phone, email, or live chat long after delivery - not just during the purchase process.
Do I need planning permission for a garden sauna in the UK?
Most traditional outdoor saunas fall within permitted development rights as garden outbuildings, provided they sit within specified size limits and are not forward of the principal elevation of the house. If your property is listed or within a designated area such as a conservation zone, separate consent may be required. We recommend checking with your local planning authority before ordering, and our team is happy to advise based on typical installation scenarios.
Do I need a dedicated electrical supply?
Electric sauna heaters in the 6 kW to 18 kW range require a hardwired, dedicated circuit installed by a qualified electrician in accordance with BS 7671 and Part P building regulations. Wood-burning heaters carry no electrical requirement at all, which makes them a straightforward option where a dedicated supply is impractical or simply unwanted.
Is now a good time to buy?
Pricing in this category does shift across the year, but what matters more than timing is buying the right specification from an authorised dealer with genuine after-sales support. If you would like to discuss your options or get a current price, contact our team directly for honest, no-pressure guidance.

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.
100% recommended
Easy to use
Looks great
100% Happy
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.
Camilla Mini 2 Person Traditional Outdoor Sauna Complete Kit

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.
