Why Returns Are Limited for Made-to-Order Saunas
Made-to-order saunas are personalised and manufactured based on specific customer requirements. As such, these items cannot be resold or restocked, which is why we are unable to accept returns or offer refunds once fabrication has begun.
We encourage you to carefully review all details of your order before confirming, including dimensions, features, and finishes.

• Customisation Acknowledgement: By placing an order for a made-to-order sauna, you acknowledge that this is a bespoke product tailored to your specifications.
• Non-Returnable Items: Once production has started, cancellations, returns, or refunds are not permitted unless the product is defective or damaged upon arrival.
• Damaged or Faulty Products:
• If your sauna arrives with damage or a manufacturing defect, please notify us within 48 hours of delivery.

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 Comfort spa comes with a 7.5kW heater. If you have a standard single phase supply (most likely), then your electrician will need to create an isolated supply and size a cable that is capable of 33 amps.
Here are links to both the data sheet and user manual for the heater, if you supply these to your electrician, they will know what to do.
Performance fabrics surpass traditional wood in saunas by offering unmatched hygiene, durability, and design versatility.
• Hygienic Benefits: Water-repellent, odour- and bacteria-resistant fabrics prevent mould and are OEKO-TEX® Standard 100 certified for safety.
• Temperature Resistance: Retains shape and functionality in high heat and humidity, ensuring long-lasting durability.
• Easy Maintenance: Simple to clean and maintain, with no special treatment required.
• Design Freedom: Customisable colours and textures allow seamless integration with any interior style, creating a stunning, personalised look.
InnoZen Fabric Saunas FAQ
Do InnoZen saunas need a drainage system?
InnoZen saunas do not require a drainage system. Moisture is naturally evaporated by the heat, while the convection heater effectively regulates the temperature within the cabin. The temperature and humidity levels below the bench remain within normal parameters.
The sauna fabrics are designed with a water-repellent surface and are treated with a moisture barrier on the reverse side to protect the insulation. During a sauna session, particularly when using the vaporiser, higher humidity may briefly condense on the fabric surface. However, the fabric dries quickly after the session—much faster than wood. In a standard Finnish sauna setting, the fabric remains completely dry throughout.
This innovative design makes InnoZen saunas ideal for indoor living spaces. They can be positioned like furniture on any hard floor surface without the need for additional drainage solutions.
Can the sauna be placed directly on the floor?
Yes, the sauna can be placed on any hard flooring. The temperature and humidity are carefully controlled within the cabin, ensuring no moisture reaches the floor during proper use.
However, if the infusion is poured over the stones too quickly or at a low temperature, some liquid may seep through and drip onto the floor. This can be easily cleaned. Similarly, any accidental spills can be wiped away without difficulty.
For added convenience, we recommend using a bath mat outside the sauna for after your session.
What makes InnoZen saunas unique?
InnoZen saunas are the world’s first to feature patented designs made of functional fabric, combined with aluminium frames. They offer customisable colour options and a modern aesthetic that complements any living space.
How long does it take for an InnoZen sauna to get hot?
InnoZen saunas heat up rapidly due to the combination of the energy efficient EOS heaters, and the amazing insulation properties of the patented fabric. You can expect it to reach 60°C in around 20 minutes, and 90°C in 40 minutes.
Are the fabrics used in InnoZen saunas safe?
Yes, the fabrics meet OEKO-TEX® Standard 100, ensuring they are free of harmful substances, skin-friendly, and safe for sauna use.
Can I customise the size of my sauna?
Absolutely! While standard dimensions are available, the modular design allows for custom sizes to fit your specific needs.
What are the benefits of using functional fabrics in a sauna?
Functional fabrics in InnoZen saunas provide several advantages:
• Temperature resistance
• Water and moisture repellency
• Odor resistance
• Easy cleaning and maintenance
What are the main differences between InnoZen’s sauna models?
• Urban Home Spa: Compact and requires only a 230V connection.
• Comfort Home Spa: Larger models requiring a higher voltage.
• Superior Home Spa: Luxury models with advanced features like a cubist design heater and optional app-based remote control.
How long does it take to receive an InnoZen sauna after ordering?
The delivery time is approximately 8–12 weeks after order confirmation.
How do I select the right fabric and colour for my sauna?
You can order free fabric samples directly for free from us by filling out the request form below. Once you’ve made your selection, we can help you choose the right sauna model and size for your needs.
How should I clean the sauna walls?
The functional fabrics used in the sauna are designed to offer superior hygiene and are easier to clean compared to traditional wood. Generally, a simple wipe-down with a damp cloth, similar to cleaning furniture, is sufficient. The technical acrylic fibers are water-repellent and do not absorb bacteria or odors. In the unlikely event of a stain, we recommend using a mild soap solution and a cleaning cloth for effective removal.
Do I need and exhaust/extraction system to be fitted?
No, the sauna features a convection heating system that draws fresh air through the air slots and efficiently regulates the internal cabin temperature. It is essential to maintain a minimum clearance of 5 cm between the sauna and the wall to ensure optimal airflow and performance.
Can I use an InnoZen sauna in my holiday home?
Yes, InnoZen saunas are designed to suit both residential and vacation properties, creating a personal wellness retreat anywhere.

Sauna dream come true!
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…. 😎
