Electrical Supply - IMPORTANT - Please Read Before Ordering

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).

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

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.

All Haljas products are made to order in Estonia, the home of the sauna. We will handle everything in terms of delivery to your doorstep, however the sauna will need to be unloaded by you the customer. Please consult this installation guide.

unloading and positioning are not included in the price. All Haljas saunas are delivered fully assembled.

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.

Maintenance

Haljas Hele Nano Outdoor Sauna 2 Seater 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.

Haljas model-specific care

For Haljas 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.

The sauna itself is 1.58 m wide, 1.14 m deep and 2.29 m high. Leave a gap around it so you can look after it:

  • Behind and each side: about 50 cmEnough to stand in, so you can clean the glass (twice a year is plenty) and reach the isolator and control box.
  • Against a wall or fence?That's fine. You just won't be able to clean the glass on that side. Ask your electrician to put the isolator on a side you can reach.
  • In front: about 90 cmThe glass door opens outward, and you want a clear, safe step in and out.
  • BaseLevel, and strong enough for about 0.7 tonnes: the sauna (400 kg), the heater and stones and up to 160 kg of people.

Haljas Hele Nano Outdoor Sauna 2 Seater - 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 price includes a Harvia The Wall 6 kW electric heater. You can upgrade to a HUUM Cliff 6 kW in "Design your sauna".

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 link under Add to Cart 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.

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 link under Add to Cart 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 Haljas Hele Nano?

Buy no paint or timber treatment before first use of the Haljas Hele Nano. It is supplied with factory-finished or specialist surfaces that should not be overcoated with a generic product.

follow the Haljas refinishing schedule.

When maintenance is due, follow the supplied manual and obtain the exact compatible finish from the sauna manufacturer or Heracles before buying it.

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.
