The Saunum Spa Session Heater is versatile and can be installed alongside a wall or in a corner of the sauna room. It's designed to heat the sauna room to temperatures ranging from 40 to 90 °C while maintaining a balanced climate, offering you a range of experiences from intense heat to a gentle, humid environment.

Embrace the therapeutic benefits of salt therapy with the patented method of enriching the air with salt ions. This feature infuses salt ions from natural salt spheres into the circulating air, reaching your skin and respiratory tract. It's especially beneficial for respiratory conditions, offering decongestant properties and antimicrobial benefits.
Health-Enhancing Features
The Saunum Spa Session Heater also incorporates an aromatherapy system. By mixing sauna essential oil aromas within the steam, it adds an extra layer of sensory pleasure to your sauna experience, making it a healthy alternative to burning aromatic oil on the hot stones.

The electrical supply required will depend on the kW rating of your chosen sauna heater. We strongly recommend consulting with a qualified electrician prior to any installation.
Typically, a dedicated supply is required—similar to those used for electric showers or cookers. Most domestic sauna heaters in the UK are connected to a single-phase 230V supply, and the Amps can be calculated using:
Watts ÷ Volts = Amps
For example: a 6kW (6000W) heater ÷ 230V = approximately 26 Amps
Below is a general guide for domestic sauna heaters:
Heater Power - Current Draw - Suggested Cable Size (Single-Phase)
2.3 kW - 10 Amps - 1.5 mm²
3.0 kW - 13 Amps - 2.5 mm²
3.6 kW - 15 Amps - 2.5 mm²
4.5 kW - 19 Amps - 2.5–4.0 mm²
6.0 kW - 26 Amps - 4.0 mm²
8.0 kW - 35 Amps - 6.0 mm²
9.0 kW - 40 Amps - 6.0 mm² (or higher, depending on cable run) Cable size depends on cable length, installation method, and other on-site factors. Always defer to your electrician’s judgment.
We strongly advise that installation is carried out by a fully qualified electrician, and that all work complies with current Government regulations and wiring standards (e.g., BS 7671 in the UK).
The Saunum Spa Session comes in 6kW and 9kW. The 6kW version can be run from a regular 13 Amp supply, but the 9kW version will require a 32 Amp supply.
We highly recommend consulting with a qualified electrician prior to installing your heater to ensure you have the correct set up.

The Sauna of the Next Century
How Does Saunums 5-in-1 Patented Technology Work?
Saunum’s patented air-blending system traps the scorching steam, that rises under the ceiling of the sauna room, mixes it with cooler air on the floor surface, and directs the soft steam back evenly. This ensures a more even temperature of the steam, and the oxygen-enriched steam makes it easier to breathe. Water can be thrown more often to produce more steam, making the sauna air more humid, and ensuring more intense sweat. With Saunum’s patented method of enriching the air with salt ions, the salt ions from the natural salt spheres added to the sauna climate device are infused into the circulating air to reach the skin and respiratory tract. An even more relaxing sauna experience is created with the help of the aroma system, which mixes sauna oil aromas with the steam. It is a healthy alternative to burning aromatic oil on hot stones.
Saunum Spa Session Heater - FAQ's
Can these saunas be delivered flat pack and assembled on site?
No, all Saunum saunas are delivered fully assembled. This is to ensure the integrity of the structure and to prevent any draughts or openings that could lead to damage.
Do I need a crane?
This will depend on the location that you wish to place your sauna. If there is sufficient access, the sauna can be positioned with a fork lift.
If I do need a crane, can you organise this for me?
We deliver the sauna to your location free of charge, however, the cost of a crane will vary significantly depending on the site. We advise that you organise your own crane/HIAB with a local contractor. If you wish, we can organise this for you, but it will always be cheaper to organise it yourself.
Why do the saunas not include a heater in the price?
There are many different specifications of Saunum heaters that cater for different budgets. Some customers already have a heater and only want the structure.
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.

Fabulous Sauna
We are delighted with our sauna. Ordering was easy and we opted for the install option too. Make sure you use electricians willing to ask for advice from the Heracles team if needed as that supports a smooth installation. Really happy that we chose Heracles. You don’t need to spend a fortune to get a quality product that does the job beautifully.

Superb!
We have now had our Leil 5 Person Sauna with Changing Room running for a few weeks - and absolutely love it. If you want very good quality and excellent service, then absolutely use Heracles. Friendly, efficient & helpful advice all the way through the process. And they ARE right about using one of their recommended electricians unless yours has done saunas before!! We used the install service - which was also perfect - and all the recommended oils (which by the way is not a quick job!). Even had some left over wood which we have used to make the outdoor shower. HUUM heater; good tip from installers - wash stones before put in basket as they have black 'dust'. And HUUM have just released a new app thank goodness as old one rubbish. Thank you Keith and team; very happy customers.

Our sauna cabin sanctuary: quality & contentment!
For years I have enjoyed the health benefits of a regular sauna - choosing to install a glazed steam shower in our urban apartment more than a decade ago.
Frequent and extensive travels into Finland, exploring the Arctic north, confirmed our dedication to therapeutic steam (and ice plunges)!
Having relocated to a rural setting, it was time - at last - for a sauna cabin in the garden.
Thorough research confirmed the quality of the Leil range and the perfect option, for us, of the "round cube double" - an elegant, robust, thermowood construction with ample space as you enter through the separate changing room onwards into the beautifully benched and glazed interior.
The Leil "round cube double" is offered with a range of upgrades, sauna heaters and lights. We chose to keep it simple: just the glazed cabin, to suit our rural setting. However, we did opt for the larger 2.6m size, so that the benches are sufficient for those over 6' to enjoy a full horizontal stretch!
From start to finish, the Heracles Wellness team offered reliable expert advice and communication, as well as very helpful liaison during the delivery and construction phase. I wanted a quality product, but I also needed quality customer care for a complex delivery and technical installation.
The installation - organised by Heracles Wellness - was completed to schedule with real attention to detail: the team of carpenters had extensive experience with sauna construction, including the Leil range.
It was very clear what was included 'in the price' and what we needed to complete ourselves after installation: the electrical connection, interior wall and bench treatments must be completed before first use.
As we await those final stages - and the first sauna in the new cabin - the Leil "round cube double" has already become an exceptional sauna cabin sanctuary: quality and contentment!
