Our Leil Black Cube Sauna has exceeded our expectations in every way. We wanted a sauna which blended with our garden setting, to provide spa like quality without crowding our outdoor space. It's elegant compact design is spacious enough on the inside to fully recline, whilst occupying a relatively small footprint. It's sleek, black exterior has allowed it to blend in with both our vegetation and existing structures.
The smoked glass windows allow us privacy whilst being able to enjoy all the benefits of our garden scenery. The interior is so comfortable we are already doubling up its use as a winter garden room, where we can enjoy observing visiting wildlife which remains oblivious to our presence.
We have opted for the HUUM heater which achieves temperature in under 30 minutes, even when its close to freezing outdoors. The heat is so even it matches anything we have experienced in specialised spa resorts, and the compact design means that half a ladle of water from the elegant bucket supplied, brings an instant zing to the whole cabin. The adjustable LEDs enhance the ambiance of the idyllic Sauna experience.
The installation process was no less pleasing. Keith and Abdullah were so easy and pleasant to deal with. They have constantly checked on my satisfaction, and helped me through all the installation process with several hints and tips. The mechanical installation team were a delight, and negotiated our narrow and inticrate entrance without fuss. A team of three worked tirelessly from dawn until dusk to complete the process in one long day. They were so pleasant, and the handover was simplified by a thorough supplied checklist.
One part of the installation which is seperate, and should not be underestimated (in price or time) is the electrics. It took 2 engineers several hours, just to wire the sauna, and it also needs a seperate supply from the mains unit, which is also a substantial activity. Fortunately Heracles supply a list of experienced electricians which allow for a more efficient and quality process.
It is also easy to overlook the foundations, and I nearly did! Our garden is on a slope and normal foundations would have been costly and time consuming. So at the last minute, I chose to employ ground screws. I was lucky to discover a company called 'No more digging'. They too were a delight to work with, and they interacted with Heracles to produce an unobtrusive substructure, that they prebuilt. This meant the entire foundation was installed inside 90 minutes at a very reasonable cost!!
This option which impressed the Heracles team, has the bonus of maintaining excellent air circulation underneath the sauna, but does raise its height such that a step access needs to be factored in.
Don't just take our word for it, but our son and daughters are visiting more regularly to enjoy the delights of this health enhancing garden Sauna. We all agree on the high quality of the Sauna aesthetics and practicality.
For anyone considering a similar venture I can thoroughly recommend Heracles Wellness and the Leil Black Cube Sauna.
Thank you Keith and the teams, this has been an unexpectedly pleasurable experience.

Here is the picture

I had been researching saunas for my garden and came across Hercules wellness. Reading the reviews I decided this was the company I definitely wanted to go with them, plus the fact that they did the choice of sauna and heaters that I wanted.
From first contact I was not disappointed and the service has been brilliant from initial enquiry to purchase and then install. Any questions I had were answered and all information supplied was fantastic.
The installation team were so efficient, polite and absolutely were experts in their field. In addition to putting up my wonderful sauna, they helped my electrician with guidance & a few tips, which was much appreciated.
The sauna itself and 6kw spirit heater I’m so pleased with, it’s been a brilliant purchase from brilliant company.
Thank you to you all and to the install team.

Apologies it had taken so long to send you this message.

We have been delighted with our sauna and our experience with yourselves has been perfect from day 1. We were initially apprehensive about the speed of delivery and we should not been concerned, as I recall the kit arrived within a couple of weeks. You advocate the use of your team of builders to construct the sauna and having built it as a kit, this I fully understand. You need to be experienced and confident to undertake yourself. That said the quality of the components was excellent and no single element caused concern.

You will be unsurprised to hear our only issue was getting the electrician back to finally connect it to the bespoke power supply we had already had installed.

Thank you again, great kit and lovely sauna.

I recently purchased the Saunasell Black Cube Premium 4 Person Outdoor Sauna Kit from Heracles Wellness, and I’m absolutely delighted with it. From start to finish, the service has been excellent.

The sauna itself is incredibly well-built, with a premium feel and a sleek, modern design that looks fantastic in the garden. The heat-up time is quick, the interior is surprisingly spacious, and the overall quality is exactly what I was hoping for. It’s been a brilliant addition to our home — both relaxing and great for overall wellbeing.

Communication and delivery were smooth throughout, and everything arrived exactly as described. I’m really pleased with the whole experience and would happily recommend both the product and Heracles Wellness.

Thanks again for a great service!

we loved it, great sauna and team super helpful- even with aftercare

After researching for 1 full year and going through possibly every sauna company in the UK, I stumbled upon Keith, Brian, and Abdullah. What an all star team, all the way through to their installation team. Not only were they kind and infinitely patient in the pre-purchase phase but this same professionalism continues even after completion. Every single other suana company lost me as a customer becuase I had many questions and ultimately they just decided I wasn't worth the time, but every one at Heracles Wellness actively made time and valued my custom. When other companies dodged questions about manufacturing details and certification of quality Heracles response was one of respect towards diligence. This was my personal #1 reason for buying from them. However, I will tell you 3 other objective things they exceed at: price point, balance of quality where it matters, and turn around time. So if you're anxious about having to wait months, or get a product that won't last, or get overcharged then look no further, you've found the best in the biz. They have a customer-centric business model. They have smart incentives and even a scheme where you can go see previous buyer's suanas. They don't cut corners or pinch pennies. They want you the customer to feel satisfied and this feels genuine from start to finish. Just give them a call and you'll see what I'm talking about. If there's one thing you don't want buyer's remorse about its a sauna. These guys will leave with buyers relief, and that's not even mentioning how you'll feel after the sauna session ;) Thank you Heracles for truly and holistically embodying Wellness.

We were looking for a nice looking sauna heater for our project and this one ticked all the boxes .
Look, quality, ease of installation.

I’d been looking for a sauna for quite a while. Because of limited access to my back garden it had to be a flat-pack unit I could carry through the house. We’ve never had a sauna in the family before and, although I knew I enjoyed them, I didn’t want to spend too much. I’m also not a big fan of the barrel-style saunas because of their round design.

I know Keith from Heracles personally and when he offered me the Modus demo unit I couldn’t resist. A friend helped me bring everything through the house, we stained it black and assembled it the next day. Installation was very straightforward. I am not keen on the understructure though, so I will probably cover it up to improve the look.

The structure itself is Nordic spruce, and with the heat the material releases a little resin from the pockets. It’s not an issue though – once it’s dry it can be scraped off. All in all, absolutely recommend it. Heats up really fast with the harvia cilindro and the steam is great! Make sure to clean the interior from dust after assembly... my first steam was... dusty!

From start to finish, the service has been nothing short of exceptional. The team were professional, friendly, and incredibly helpful throughout the entire process. The installers did a brilliant job, efficient, tidy, and made sure everything was set up perfectly. I couldn’t be happier with my new sauna; the quality is outstanding and it’s already become my favourite place to relax. Dealing with Heracles Wellness has been a pleasure, and I would highly recommend them to anyone considering a sauna.

We are so pleased with our sauna. To start with, it looks amazing, and the quality is really impressive. The lighting and juniper wall are incredible and having it all WiFi enabled is great.

I went to see a sauna the team had supplied and fitted at a previous customer’s house which really helped with the decision making (although I warn you that you will end up upselling yourself!)
Keith and Abdullah were really helpful all the way through the process in terms of ordering, and managing the delivery and installation arrangements.

We are thrilled with our Sauna, delivered nice and fast.

The materials are lovely and the kit has everything to get you going.

I was throughly impressed how good good the unit it is, and it seems to be a better price than anywhere else.

The only thing I would say is that instructions could do with some work.

I can’t recommend Heracles enough the service and product are first class, Ordering , delivery and installation completed within 2 weeks, where as I had been waiting for over a year from another company.

Keith was first class with all his advice and the installation team completed the install in about 6 hours truly a faultless service.

Thank you all for our lovely sauna 2 very happy customers.

Steve and Julie

Great unit, great staff. Awesome high quality product. Thanks

When we first seriously starting thinking about installing a sauna at home we did a lot of research about the different companies and products available. Heracles Wellness stood out from the crowd, both with the detailed information available on their website and the number of glowing customer reviews.

A helpful call with Keith later on in the process helped answer all our questions around ongoing maintenance needs, installation concerns and costs, particularly around the electrical install which, depending on the planned location of your sauna can be a considerable extra expense.

Delivery and installation was prompt, efficient and at a time that suited us. Communication throughout was timely, friendly and helpful. We elected to have the Heracles team install the sauna and we are so glad that we did, the quality of the build is truly excellent.

We couldn't be happier with our sauna set up and know that we'll only continue to see the benefits and enjoyment of it as the darker nights draw in. I wouldn't hesitate to recommend Heracles Wellness and advise anyone who is thinking about installing a home sauna to do it, you won't regret it!

Customer from East Sussex. On 23 July 25 my sauna kit was delivered and on 25 July 2025 it was assembled. I had great experience with Heracles Wellness. I chose them among a wide range of companies due to their great reviews, thorough information on the website, competitive price and great support through the purchase, delivery and assembly service. I had my initial chat with Keith on the website. He was amazing and really patient with all my many questions. This an expensive investment for my family and Keith was great to ensure understand all aspects of this purchase and warranty. Then, it was Abdullah who took over updating me on every step and booking delivery and assemly. I do not recall the name of the delivery person, but he was ever so careful and polite. The assembly team, Pavel’s team arrived on time and worked non-stop to put the sauna together. I really recommend assembly as it is hassle free service. I had my own electrician connecting the sauna which was quick. I might need to mention that the reset button on the heater may require some force as switch is stiff when you. We were afraid to apply the force not to break anything and the sauna did not heat up more than 49 degrees Celsius. We found the information about adding some force initially on support Harvia website. The sauna heated the first time in about 39-35 minutes to 90 degrees. We had a go with my family and it was AMAZING 🤩. We will be enjoying the sauna more often from now on as it has a lot of health benefits. My skin was rejuvenated after the session. We already applied the Tikkurila sauna protection oil inside out, as recommended on the HW website. It made the wood just slightly darker, cheek blush effect I called it :). Also added an extra pleasant fragrance to the wood. The wood smell inside the sauna is also great. All in all, I am ever so grateful to HW guys. I hope the sauna will work well and serve us many years of joy. I strongly recommend HW for being professional and supportive! Adding some photos to convince those who are in decision mode…. 😎

Keith and Brian have been amazing with their support and communications regarding this outstanding piece of kit. They definitely deserve their 5 star ⭐️ review. Exceptional service.

The service from Keith and Heracles generally has been 5 star ⭐️ and this has continued post the sale of this equipment. I cannot tecommemd them highly enough.

Really nice quality product that looks great. We use ours a lot for contrast therapy, sauna and ice bath. It is as good as any sauna I have used in spas or hotels. I recommend the installation team they were punctual, tidy and really professional. Keith and the team have been really helpful with technical support for our electrician. Aftercare service is excellent. I highly recommend.

Quality product. Still have to do the internal assembly but the external build is complete. I quickly wished I had paid for the installation to enjoy the sauna out of the box experience. The assembly costs are more than fair for the amount of work involved.

We’ve only had the sauna installed for a few days and have yet to give it a proper go, but the product is very high quality. The wood smells fantastic and it looks great. My advice would be to use the installation team to build it for you. Unless you have some skills or a lot of time on your hands, it would be a big job to do it yourself, and if you’re going to spend this much money on the sauna, you want it done well. The installers were excellent, very polite and hard working. Heracles themselves have been excellent to deal with throughout. Keith has made time to answer a lot of questions from me and provided comprehensive answers throughout including help on the day my electrician arrived to hook up the sauna. Overall, impressive.

The sauna itself that really shines. Nestled beautifully in a small garden space, it manages to feel both secluded and immersive – a true sanctuary in the heart of London. The design is sleek yet natural, blending well with the outdoor environment and adding a serious wow-factor to the space.

The customer service and communication was excellent and the actual sauna itself is beautifully finished

My new Sauna from Heracles not only looks incredible but has exceeded my expectations in terms of experience. Keith and his team gave me the confidence to take this big step after looking through countless different sites and options. This is possibly the best company I have dealt with in terms of user experience which is completely online. Option of speaking to a fellow buyer is unique and helped me with decision making….So well done team and hope to enjoy this for many years to come!!

The Sauna was delivered on time and safely, the installation team were flexible and turned up on time and really did a great job quickly! Really impressed with the quality of the sauna, the excellent installation and the superb support from the Heracles team - thank you!
