Delivery & Installation

Suncube saunas are delivered fully assembled.

Delivery to your doorstep is included in the price, however, unloading is not as every site is different. You will need either a fork lift, HIAB or crane to get your sauna into position.

To protect the sauna’s base frame, it is recommended to install the sauna above ground level. Place a water-resistant material, such as bitumen strips, between the base frame and the surface to prevent direct contact with the ground.

Assembled Deliveries

Assembled saunas cannot be offloaded by hand. Depending on access, you have three options: forklift, HIAB, or crane.

Forklift: If there is enough space to move the sauna from the truck to its final position, a forklift is the most cost-effective option.

HIAB: For lifting the sauna over a fence or wall near the road, a HIAB is a practical and affordable choice.

Crane: If your sauna’s final position is far from the road and lacks forklift access, a crane will be necessary.

If you’re unsure of the best solution, feel free to contact us for advice or assistance in finding the right option. We can also book it on your behalf for an extra fee.

Warranty

The Suncube M Sauna comes with a 2-year manufacturer’s warranty, ensuring peace of mind and long-lasting quality. This warranty covers defects in materials and workmanship under normal residential use, starting from the date of delivery.

Covered under the warranty are the structural CLT (Cross Laminated Timber) panels, benches and seating, as well as all factory-installed systems and components. This includes the heater and lighting components.

Please note, the warranty does not cover issues arising from improper installation, normal wear and tear (such as minor wood warping or discolouration), neglect, misuse, poor maintenance, or damage caused by environmental factors like storms or excessive snow. It also excludes unauthorised modifications or the addition of third-party products after delivery.

Should a fault occur, all warranty claims must be submitted directly to Heracles Wellness within 30 days of the issue being discovered. Claims must include a detailed description and clear photographs of the defect. Any repair work must be carried out either by Suncibeor an authorised service partner unless agreed otherwise in writing.

For the first 12 months following delivery, all repair, replacement, shipping, and labour costs are fully covered. From months 13 to 24, replacement parts are provided free of charge; however, shipping and labour costs may apply.

This warranty is non-transferable and applies only to the original purchaser at the original installation address. Suncubes' liability under this warranty is limited to the original purchase price of the sauna and does not extend to any indirect or consequential damages.

Return and Refunds

Returns and Refunds Policy for Made-to-Order Saunas

At Heracles Wellness, we take pride in offering high-quality, made-to-order saunas tailored to your unique needs. Due to the bespoke nature of these products, our returns and refund policy is designed to reflect the custom craftsmanship involved.

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.

Our Policy in Detail

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.

• 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:

• Bespoke and made-to-order products are exempt from the standard 14-day cancellation period for online sales.

• However, your rights remain protected if the product is faulty or does not match the agreed-upon specifications.

If you have concerns about your order, please contact us at info@heracleswellness.co.uk. We’re happy to assist and ensure your satisfaction with our products.

Maintenance

SunCube L 4-6 Person Outdoor Sauna with Changing Room 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.

SunCube model-specific care

For SunCube saunas, follow the supplied manufacturer manual for exact timber treatment, cleaning, heater and roof-care requirements.

• If the sauna has factory-finished or specialised cladding, do not apply ordinary paint, varnish, or household wood products unless the manufacturer confirms they are suitable.

SunCube L 4-6 Person Outdoor Sauna with Changing Room - FAQ's

How many people can the SunCube L sauna accommodate?

The SunCube L sauna comfortably fits 4-6 people, making it ideal for families or small groups.

What materials are used for the interior and exterior?

The interior is crafted from Thermory Aspen for a smooth, elegant finish, while the exterior features durable Thermory Pine.

Is a changing room included with the sauna?

Yes, a spacious changing room vestibule is included for privacy and convenience before entering the sauna area.

Can I customize the glass tint?

Absolutely! You can select your preferred glass tint to personalize the sauna’s appearance and privacy level.

How does the sauna maintain even heat distribution?

Thanks to its patented design, the SunCube L ensures fast, efficient, and uniform heat distribution throughout the interior for optimal comfort.

What are the exterior dimensions of the sauna?

The sauna measures 229cm wide, 240cm high, and 329cm deep, offering plenty of space for enjoyable sessions.

Is the SunCube L suitable for all weather conditions?

Yes, the Thermory wood and robust construction make it resistant to changing weather, ensuring lasting performance outdoors.

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.

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.
