Electrical Supply - IMPORTANT - Please Read Before Ordering

Electrical Installation – Important Information

If you hire our installation team to build your sauna, please note that internal electrical wiring is not included and must be completed by a certified electrician.

Our installation team will:

Mount the sauna heater to the wall (where applicable)
Attach the LED light strips to the benches

However, the following must be completed by a qualified electrician:

Final wiring and connection of the heater
Final wiring of the LED lighting
Installation and wiring of external control panels, door sensor, thermostat, and any other electrical components (not applicable for manually controlled heaters such as the Harvia Vega BC60).

Electrical Supply Requirements

A sauna heater typically requires a dedicated electrical supply, similar to those used for electric showers or cookers.

Most domestic sauna heaters in the UK operate on a single-phase 230V supply. The current draw can be calculated using the following formula:

Watts ÷ Volts = Amps

Example:

6kW (6000W) ÷ 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).

Sauna Heater Manuals

For exact electrical requirements of each heater please refer to the installation manuals below. If you provide these to your electrician, they should be able to advise you of the necessary wiring.

Delivery & Installation

Saunasell saunas are delivered in a pallet by default, and come with detailed installation instructions. You can view these instructions here.

Delivery Information

Delivery to your address is included in the price for all saunas. Because our saunas are large and heavy (typically around one tonne), the exact unloading process depends on whether you choose a flat pack kit or a fully assembled sauna.

Flat Pack / DIY Assemblies

Flat pack saunas are delivered on a pallet. We will unload the pallet onto your driveway using a forklift or HIAB truck, depending on site access. This service is included in the delivery price.

From there, the sauna components can be carried to the installation location and assembled.

Factory-Assembled Saunas

If you choose to have your sauna built in the factory and delivered fully assembled, delivery to your address is included, but unloading is not.

Fully assembled saunas are very heavy and typically require a forklift or crane to lift them from the truck and position them in place. You can arrange this locally, or we can organise it for you for an additional fee.

Please contact us if you would like us to arrange the unloading.

Warranty

At Heracles Wellness, we are confident in the quality of the Leil® products we offer. That’s why we provide a warranty on all Leil® products, with the warranty period depending on who carries out the installation:

• 24 months when the product is installed by the Heracles Wellness Install Team

Full warranty terms can be found in the user manuals, but the main points are below:

• The warranty applies only where the product has been used and maintained in accordance with the relevant user manuals.

• Warranty periods may differ for products mounted on trailers and for commercial-use products.

• The warranty does not cover natural characteristics of wood, including discolouration, dimensional changes, or cracking caused by fluctuating or excessive humidity.

• The warranty does not cover normal wear and tear, or damage caused by improper installation, misuse, or incorrect storage.

• Weather-related damage, including damage caused by thunder, is not covered.

• Damage resulting from incorrect installation by the client or their chosen installer is excluded from cover.

• The warranty will be void if unauthorised repairs or modifications are carried out, or if the product is used for anything other than its intended purpose.

For any warranty-related queries or to submit a claim, please contact us at info@heracleswellness.co.uk.

Maintenance

Leil® Round Cube Relax Outdoor Sauna 6 Person is designed for outdoor use, but it is not maintenance-free. A small amount of regular care will help protect the timber, keep the sauna clean, and prevent avoidable issues over time.

After each use

• Wipe down wet benches, backrests, floors and high-contact areas.

• Leave the door and vents open until the interior has dried properly.

• Do not leave wet towels or accessories inside the sauna.

Cleaning

• Clean periodically with warm water, a soft cloth or brush, and a mild sauna-safe cleaner.

• Avoid harsh household chemicals, bleach, ammonia, abrasive cleaners, or normal interior varnishes.

Benches and backrests

• Sit on towels during use to reduce sweat staining.

• If bench timber becomes dry or marked, it can be lightly cleaned, gently sanded if needed, and treated with a sauna-suitable bench protection product where appropriate.

Doors, hinges and timber movement

• Outdoor timber naturally expands and contracts with heat, humidity and weather.

• Minor door or hinge adjustments may occasionally be required. This is normal routine maintenance rather than a product fault.

Heater stones

• Inspect sauna stones regularly, especially with frequent use.

• Replace stones if they become cracked, crumbly, heavily discoloured, or start breaking down.

• Stack stones loosely enough to allow airflow around the heating elements. Only use proper sauna stones, not garden or beach stones.

Exterior, roof and exposed locations

• Check the exterior, roof, fixings, hinges, vents and drainage periodically, especially after storms or long wet periods.

• Coastal, shaded, very exposed, or high-rainfall locations may need more frequent maintenance.

• In coastal or sea-air locations, exposed metal parts such as hinges, fixings and brackets should be checked more often and given extra corrosion protection where appropriate, such as WD-40 or a suitable zinc-based protective spray.

• In windy or exposed locations, check that any parts vulnerable to wind lift or movement are properly secured. This can include roof shingles, trims, covers and lightweight external fittings. If needed, use additional suitable fixings, adhesive, or restraints in line with the manufacturer’s guidance.

Manuals

• Always follow the specific manual supplied with your sauna and heater. If the manual gives different maintenance instructions, the manufacturer’s manual should take priority.

Leil Round Cube paint and treatment

The Leil Round Cube range is supplied with the manufacturer’s recommended paint/treatment where applicable. Apply it according to the supplied installation instructions and manual.

• Even where paint or treatment is supplied, the sauna is not maintenance-free.

• Inspect exterior timber, painted areas, roof, hinges, benches and heater stones regularly.

• Thermowood and factory-finished timber can still weather over time if exposed to sun, rain, salt air, or standing moisture.

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.

• Damaged or Faulty Products:

• If your sauna arrives with damage or a manufacturing defect, please notify us within 48 hours of delivery.

• We will assess the issue and may offer a repair, replacement, or refund, depending on the situation.

• Order Review: We strongly recommend double-checking all measurements and customisations to avoid errors.

• Right to Cancel (Prior to Fabrication): You may cancel your order before fabrication begins, subject to an administration fee.

Relevant Consumer Laws

Our policy aligns with your rights under UK consumer protection laws, including:

• Consumer Rights Act 2015: This law ensures products must be of satisfactory quality, fit for purpose, and as described. If your sauna does not meet these standards, we will take appropriate action to resolve the issue.

• Consumer Contracts (Information, Cancellation, and Additional Charges) Regulations 2013:

Meet the Round Cube Relax, the ideal sauna for those who love reclining in the sauna. With its generous space for up to 6 people, it’s perfect for lounging and stretching out comfortably on the sauna bench.

Due to the U-shaped layout, the heater is incorporated inside the sauna stage, meaning that only an electric heater is available with this sauna model.

Exclusive Design and Superior Craftsmanship

The Round Cube Relax boasts a unique, design-protected shape that stands out in any setting. Its mirror glass exterior and premium materials, including 40mm thermowood walls and a premium shingle roof, make it a true masterpiece of modern sauna architecture.

Spacious Enough to Entertain

Round Cube Relax – a thoughtfully designed one-room sauna spanning 6 square meters. This model redefines compactness and ultimate relaxation, featuring a U-shaped bench layout for better reclining in the sauna. With an interior depth of 1.60m, thanks to its U-shaped bench, the sauna model comfortably fits up to 6 people. Whether you prefer to sit or recline during your sauna session, both options are possible thanks to its clever room layout.

Health and Wellness Benefits

Immerse yourself in the healing aroma of the handcrafted juniper walls and only available for this range and enjoy the therapeutic effects of the HUUM heater. The sauna’s efficient air circulation and 3-step aspen bench ensure optimal heat distribution, promoting detoxification, improved circulation, and muscle relaxation

Luxurious Interior Details

Every detail inside the Round Cube Relax has been meticulously crafted. The dimmable LED lighting creates a serene atmosphere, while the natural wood finish and ergonomic backrests provide unparalleled comfort. The full circle arches and double mirror glass front wall add to the sauna’s aesthetic appeal.

Advanced Features for Enhanced Experience

Equipped with tempered mirror glass doors, Nerostep plastic grid mats, and heat protective bedding, the Round Cube Relax is designed for convenience and safety. The digital control panel allows for easy customisation of temperature and lighting to suit your preferences.

Eco-Friendly and Energy Efficient

The use of thermowood not only ensures durability but also makes the sauna environmentally friendly. The energy-efficient heating system minimises power consumption, making it a sustainable choice for your home.

Imagine the transformation this will bring to your Garden

Leil® Round Cube Relax Outdoor Sauna 6 Person - FAQ's

Does installation include the electrical connection?

No. Our installation team can assemble the sauna, but the heater and any other electrical components must still be connected by a qualified electrician.

You will need a suitable electrical supply and, at minimum, an isolator switch. Full details are provided in the Electrical Supply section on the product page.

Can any qualified electrician connect the sauna, and do you provide guidance?

Yes. Any qualified electrician should be able to connect the sauna, provided they follow the electrical requirements listed in the Electrical Supply section of the product page.

After you place your order, we also send further information that you can pass on to your electrician.

Can you recommend an electrician for the final connection?

In some cases, we may be able to share details of electricians who have connected saunas for previous customers.

Availability will depend on your location, and you are also welcome to use your own qualified electrician.

How long does professional assembly take?

Assembly time depends on the model, access, and site conditions. Many outdoor saunas can be assembled in around one day, while larger or more complex models may take longer.

We confirm the expected installation time as part of your installation quote.

Is the Heracles installation team experienced with this model?

Yes. Our installation team uses specialist carpenters and installers who are experienced in assembling outdoor saunas, which is one of the reasons many customers prefer professional installation.

What sort of base does the sauna need?

Outdoor saunas should be installed on a solid, level, well-drained base that is suitable for the size and weight of the model you are buying.

Suitable options can include a concrete pad, paving, tiles, or structurally suitable decking, provided the surface is flat, stable, and able to support the load without movement.

We also recommend positioning the base far enough away from walls, fences, and other obstructions to allow access for future wood treatment and maintenance, and to ensure the fuse box can still be accessed when needed.

What makes the Round Cube Relax different from other Round Cube models?

The Round Cube Relax is designed specifically for buyers who want more room to recline during their sauna sessions.

Its U-shaped bench layout and generous internal depth make it especially well suited to stretching out and lounging in a way that more conventional layouts do not.

Why is only an electric heater available on the Round Cube Relax?

Because of the U-shaped layout, the heater is incorporated inside the sauna stage on this model.

That design means the Round Cube Relax is available with an electric heater only.

How many people can the Round Cube Relax comfortably accommodate?

The Round Cube Relax is designed for up to six people, while still allowing plenty of room for more relaxed seating and reclining thanks to the U-shaped bench layout.

Is the Round Cube Relax a good option if I want to recline in the sauna?

Yes. This is one of the main reasons buyers choose the Round Cube Relax.

Its U-shaped bench layout and approximately 1.60m internal depth make it particularly well suited to reclining and stretching out more comfortably than many standard outdoor sauna layouts.

Do you carry out site visits before installation?

No, we do not usually carry out site visits before installation.

In most cases, customers can send us photos, measurements, site plans, and access details, and we can advise whether the proposed location looks suitable.

This is normally enough for us to highlight any obvious issues with access, base preparation, or positioning before the installation goes ahead.

Why has my sauna door gone out of alignment over time?

In outdoor saunas, it is normal for the timber structure to respond to changes in temperature, humidity, and ambient conditions over time. This can occasionally cause minor movement in the door opening, which may affect how the door closes or sits within the frame.

For this reason, sauna door hinges are designed to be adjustable. Minor door or hinge alignment adjustments over time are normal and should be carried out in line with the manual as part of routine ownership maintenance, rather than being treated as a product fault.

Can I see one of your saunas in person before ordering?

We do not currently have a full showroom, but many of our existing customers are happy to show their sauna to prospective buyers.

If you would like to see one in person, please contact us and we can try to arrange a viewing with a customer in or near your area.

Do outdoor saunas need regular maintenance?

Yes. Outdoor saunas are not maintenance-free.

As a minimum, owners should expect to inspect and re-treat exposed timber at least every 12 months, or sooner if the manufacturer manual and local conditions require it.

You should also expect to make minor door or hinge adjustments over time in line with the manual, as timber structures naturally move slightly with changes in temperature and humidity.

In coastal or sea-air environments, exposed metal parts should be checked more regularly and protected with a rust-proof treatment such as WD-40 or another suitable anti-corrosion product.

Sauna heaters also require maintenance in line with the manufacturer manual. This normally includes periodically checking, washing, and restacking the stones, and in the longer term electric heater elements may need replacing if they wear out.

We do not currently operate a formal maintenance programme, but if you would like help, please contact us and we can quote for an annual service of your sauna.
