We encourage you to carefully review all details of your order before confirming, including dimensions, features, and finishes.

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.
I used Keith and his team on another product and when I saw they also did hot tubs I knew I could rely on them to provide advice over selecting the correct model to meet my needs. I’ve had this a couple of weeks and it is absolutely fantastic.
Great service.

Just what I wanted
I have been a sauna user for the past 6 years, but when we moved house I needed to have a new one, and this Jaquar is best quality and a very good design. It heats up quickly and is smart and economical. My only criticism is the brochure and operating instructions which need attention and a rewrite! Otherwise excellent and happy. I think it is extremely well made and I am surprised at the quality of the wood.

Brilliant product, installation and service
I had a great experience throughout purchasing my sauna with Heracles. Keith was really patient through the whole process while a decided the best option. I went with the Camilla through his recommendation and I couldn't be more pleased with it. The quality of the materials are superb and the sauna performance exceeded what I was expecting. I went with the installation option which I would recommend if you are not an experienced DIY person Construction took about 3-4 hrs which is much quicker than I would have been able to do! Fitting the electrics was a big job and I was fortunate to have a neighbour do this but don't underestimate this part. Overall a fantastic experience with a great company.

Delighted with our sauna. Perfect for a London Victorian terrace
Heracles have been amazing from point of enquiry to after care check ins. Keith and the team kept us informed throughout, delivery occurred without a hitch and the install team were efficient and courteous.
The sauna quality is amazing. We asked for a smaller size due to having a Victorian terrace in London and trying to balance a bit of a garden for kids still kicking a ball around and Heracles created a bespoke option.
Easy to use (2 buttons and 1 is to set a timer). We followed the pre delivery directions from Heracles and shared pictures of the route from street to garden before arrival.
We are extremely happy and happily recommend this sauna and Heracles.
