Delivery & Installation

These sauna kits are delivered from our warehouse in Essex. Delivery is free throughout the UK Mainland.

Delivery times are between 3 to 5 working days.

After your order is placed, we will contact you to request photographs or, preferably, a short video of your delivery access. This helps us confirm the access with our logistics partners before delivery and agree how the sauna kit will be unloaded safely.

Our sauna kits are delivered on a pallet by tail-lift vehicle as standard and include comprehensive installation instructions. You can view these instructions here.

Delivery is kerbside or driveway only, where safe and practical. The delivery vehicle unloads using a tail lift and the pallet is moved with a manual pump truck.

The unloading area must be flat, solid, level, and suitable for a pump truck. Pump trucks cannot be used safely on gravel, loose stone, grass, steep inclines, steps, uneven ground, narrow access, or soft surfaces.

If standard unloading cannot be completed due to unsuitable access, the customer is responsible for providing suitable assistance, equipment, or an alternative unloading arrangement. Any additional costs for failed delivery, redelivery, handball unloading, specialist vehicles, or extra labour may be charged to the customer.

For gravel or loose surfaces, boards or another suitable temporary surface must be provided by the customer before delivery if they want the pallet moved across that area.

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.

• 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.

Maintenance

Modus Outdoor Sauna 3-4 Person with Harvia Cilindro PC70 Heater and Stones - Kit 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.

Modus model-specific care

For Modus 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.

Superior Insulation & Heat Retention

Experience exceptional warmth with 60mm-thick Cross-Laminated Timber (CLT) panels that lock in heat longer, maximising your relaxation time and energy efficiency.

What is CLT? CLT is an advanced building material made by layering solid timber boards at right angles and bonding them under high pressure. This cross-lamination technique creates a panel that is exceptionally strong, dimensionally stable, and highly resistant to warping.

For sauna use, CLT’s dense structure and layered design provide outstanding natural insulation, ensuring the cabin heats up quickly, retains warmth for longer, and keeps cold air out — even in extreme winter conditions down to -25°C.

With CLT, you’re not only getting superior heat retention and comfort, but also a sauna built to last with the same robust technology used in modern eco-builds and sustainable architecture.

Harvia Cilindro PC70 6.8kW Heater and Stones Included

The Modus comes complete with the Harvia Cilindro PC70 Black Steel heater, chosen specifically for its perfect balance of power, efficiency, and style. With a 6.8 kW output, it’s ideally matched to the Modus’ 4.4 m³ interior, ensuring fast heat-up times and consistent temperatures. Its tall, pillar-style design holds a large volume of stones, producing luxuriously soft steam and allowing you to control the intensity by throwing water either onto the top for a gentle mist or deeper into the column for a stronger burst of heat. Finished in sleek black steel, it complements the modern design of the Modus while delivering a truly authentic Finnish sauna experience.

Customisable Modern Aesthetic

Create your perfect look! The Modus’ modular design allows you to choose panels, finishes, and layouts to match your taste. Delivered with untreated CLT, the exterior can be painted, stained, oiled, or left natural — giving you complete freedom to blend your sauna seamlessly into your outdoor space or make a bold design statement in any colour you like.

You also decide how open or private the sauna feels: select as many glass panels as you want for panoramic views, or keep more solid timber walls for privacy and a cozy cabin feel.

Make it your own for personalised style and effortless outdoor integration.

Effortless Assembly

The Modus is designed to be as easy to set up as it is to enjoy. Delivered flat-packed on a pallet weighing 650kg and measuring 1990 × 740 × 1010mm, it arrives in a compact form for simple, cost-effective transport.

Our delivery team will unload the pallet using a tail-lift truck and roll it into place with a pump truck. If your drive is smooth and level, it can be positioned directly onto your property. Please note that pump trucks cannot travel across gravel or steps — in these cases, the sauna will be delivered as close as possible to your door.

Once in place, assembly is straightforward: with just two people and basic tools, you can expect to have the structure up and ready in around three hours

Modus Outdoor Sauna 3-4 Person with Harvia Cilindro PC70 Heater and Stones - Kit - FAQ's

How long does assembly take?

With two people and basic tools, assembly can be completed in about three hours using the included instructions.

Is the sauna insulated for cold climates?

Yes, the full CLT construction provides excellent insulation, suitable for outdoor use in temperatures down to -25°C.

Are both wood-fired and electric heaters compatible?

Absolutely! The Modus is designed for either wood-fired or electric heater options, giving you full flexibility.

Can I customise the finish?

Yes, the sauna is delivered with untreated wood, ready for oiling, painting, burning, or natural aging—choose your favourite finish.

Is the Modus Cube suitable for relocation?

Yes, it can be fully disassembled and reassembled without any damage, perfect for easy moving or storage.

How much space does the sauna require?

The exterior footprint is 201 cm wide by 151 cm deep, making it a compact yet comfortable solution for most outdoor spaces.

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.

Simple. Great value.

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!

Hi David!

Thank you for taking the time to leave a review for our Modus Outdoor Sauna. We're happy to hear that you found it to be a simple and great value option. We understand the importance of limited access, so we're glad our flat-pack design was able to meet your needs. We're also glad you were able to take advantage of the demo unit offer.

We appreciate your feedback on the understructure and will take that into consideration for future improvements. We're glad to hear that the Nordic spruce material and Harvia Cilindro heater are working well for you and that you're enjoying the steam. Thank you for the tip about cleaning the interior after assembly, we'll be sure to pass that on to our customers.

Thank you again for your review and for choosing our Modus Outdoor Sauna. Happy steaming!
