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

Delivery & Installation

Delivery pricing and regions

Delivery is included in the product price for eligible sauna orders to mainland England and Wales, excluding the Isle of Wight and Isles of Scilly.

Mainland Scotland delivery supplements of £399 or £749 including VAT apply by postcode and are shown at checkout.

Northern Ireland, the Republic of Ireland, Scottish islands, BFPO, Europe and every other international or offshore destination require an individual quotation before ordering.

Eligible Scottish customers can select free collection from our private Widnes warehouse. Collection is by appointment and may be made personally or by a nominated carrier.

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

Delivery Information

Delivery pricing depends on the destination, as explained above. 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.

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.

How to Contact Us

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

Leil® Primo Mini 2 Person Outdoor Sauna 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 model-specific care

Follow the supplied Leil manual for model-specific timber treatment, roof care and heater guidance. If treatment or paint is supplied with the sauna, apply it exactly as instructed during installation.

• Inspect exterior timber and exposed finishes at least annually, or more often in coastal, shaded, or very exposed locations.

Leil® Primo Mini 2 Person Outdoor Sauna - FAQ's

When will I receive my order?

The estimated delivery window is currently ….

This is an estimate rather than a guaranteed delivery date. The timing can vary depending on production schedules, dispatch arrangements or other unforeseen delays. If you need the product by a particular date, please call us before placing your order so we can check the current schedule with you.

Does this sauna include a heater?

Yes. The £3,999 complete kit includes the Harvia Vega Compact BC35 3.5kW electric heater and 12kg of sauna stones.

The BC35 has built-in controls, so it does not need a separate external controller. Final wiring must be completed by a qualified electrician; electrical connection is not included with sauna assembly.

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.

Use the Request an Installation Quote button above the options and complete the form. We will confirm the expected installation time with your 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.

Is the Primo Mini a good option for smaller outdoor spaces?

Yes. The Primo Mini is designed to give you the premium Primo design language in a more compact footprint, making it a strong choice for smaller gardens, patios, or tighter outdoor layouts.

What is the benefit of the 70mm Thermowood construction?

The thicker 70mm Thermowood walls create a more substantial, premium feel and contribute to strong thermal performance and long-term durability in outdoor conditions.

What kind of floor does the Primo Mini have?

The Primo Mini has a waterproof PVC floor, which makes it practical for sauna use and easier to clean than a standard timber floor.

What lighting options are available on the Primo Mini?

The Primo Mini can be fitted with optional exterior and interior LED lighting.

Exterior LED strips run along the outer corners, while the interior lighting uses dimmable LED strips under the bench and behind the backrests to create a more ambient sauna experience.

Do you carry out site visits before installation?

No. We do not carry out site visits.

To request an installation quote, use the Request an Installation Quote button above the options and complete the form with photos, measurements, site plans, access details and the proposed sauna location. Our installation team will use that information to assess access, base preparation and positioning, and flag any obvious issues before installation.

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 offer a formal maintenance programme.

What paint or treatment should I use on my outdoor sauna?

If your sauna has exposed or untreated exterior timber, use a breathable, UV-resistant and water-resistant exterior wood treatment. We recommend Tikkurila Valtti Plus Kesto or Tikkurila Valtti Plus Color. If you prefer a clear, natural finish, Osmo UV Protection Oil is a good option.

Apply the treatment after assembly and before regular use, then inspect the timber annually and re-treat it as required for the product and your site’s exposure.

For sauna-room walls, window frames and door frames, use Tikkurila Supi Sauna Finish or Tikkurila Supi Sauna Wax. For benches and backrests, use Tikkurila Supi Laudesuoja Bench Protection. Never use ordinary exterior paint, varnish or household wood treatments inside the heated sauna room.

If your sauna has factory-finished or specialist cladding, follow the supplied manual and do not overcoat it unless the manufacturer confirms the product is suitable.

These recommendations are general guidance. Check both the sauna manufacturer’s manual and the treatment manufacturer’s instructions, and satisfy yourself that the product is suitable for the timber and any existing finish before applying it. If you are unsure about a colour, request samples from the manufacturer or retailer and test one on a spare timber offcut or a small, inconspicuous area first.

How much treatment should I buy for the Leil Primo Mini?

Buy two 0.9-litre tins (1.8 litres total) of Tikkurila Supi Sauna Finish for the sauna-room walls and ceiling, and one 1-litre tin (1 litre total) of Tikkurila Supi Laudesuoja for the benches and backrests. For untreated exterior timber, buy either one 2.7-litre tin and one 0.9-litre tin (3.6 litres total) of Tikkurila Valtti Plus Kesto or three 0.75-litre tins (2.25 litres total) of Osmo UV Protection Oil Extra for the specified two-coat systems.

The buying calculation uses 11.86 m² interior requiring 1.7 litres, and 1.99 m² of bench timber requiring 0.29 litres, with 11.84 m² outside requiring 3.4 litres of Valtti or 1.51 litres of Osmo. It uses the lower published coverage rate and one coat inside, two coats on untreated exterior timber, with a 15% allowance. Glass, roof shingles or membranes, the underside and confirmed factory-painted trim are excluded.

These are conservative buying allowances. Follow the current label and technical sheet for the product you choose; if its coverage or coat count differs, use those figures instead.

Can this sauna be used commercially?

Yes. Our traditional saunas are suitable for commercial use, and we already supply many commercial customers.

Commercial use requires a regular maintenance regime, as it would with any sauna. This includes cleaning the sauna, inspecting and maintaining the heater stones, and re-treating or painting the timber when required. The frequency will depend on usage, location and the manufacturer's maintenance instructions.

🎄 Want your sauna delivered and installed before Christmas?

We strongly encourage confirming your order by 31 October. Orders confirmed in early November may still be possible, subject to availability.
