Prepare your outdoor site

Plan a hard, level, well-drained base, the full roof footprint, door clearance and an accessible delivery route. The outdoor shell still needs seal checks and routine care. Electrical work and any controller upgrade require a licensed electrician.

The current standard 6 kW model requires a dedicated single-phase 32 A hardwired supply. Optional heater upgrades change the electrical requirements. Your licensed electrician must confirm the actual heater and current installation manual before work starts.

Does it include WiFi control?

The Harvia Fenix WiFi controller is an optional upgrade, subject to heater compatibility and installation requirements. It is not included as standard.

Compare the larger Demfin 6 if you want more cabin width.

Care and warranty conditions

Keep the cabin on a hard, level, well-drained base. Use towels on the seating, clean according to the manual and allow the cabin to dry after use. On outdoor models, inspect window and door seals every 12–18 months and renew outdoor-grade silicone when needed. Natural timber ageing, neglected seals, standing-water damage and incorrect installation are excluded from the manufacturer warranty.

Manufacturer warranty

For home use, Innerlight’s current warranty policy lists 10 years for the frame, structure, other parts and outdoor floor, with 2 years for the Harvia heater. Labour and shipping are covered for the first 12 months; subsequent cover is parts only. Commercial or shared use carries 12 months from delivery. These manufacturer warranties are additional to your rights under Australian Consumer Law. Contact NORD SAUNAS with your order number, serial number and photos for help with a claim.

Frequently Asked Questions

Do I need an electrician to install a sauna?

Yes — all electric saunas require a dedicated hardwired circuit installed by a licensed electrician. You will need a minimum 32A circuit breaker (we recommend 40A) with an RCD safety switch. This is a straightforward job for any qualified sparky and typically takes 2–3 hours. We will send you the full electrical specifications sheet before delivery so you can brief your electrician in advance.

How long does delivery take?

Delivery timeframes vary by product and your location. Australian metro areas typically receive delivery within 3–10 business days from order confirmation. Regional and rural areas may take longer. Your estimated arrival date is shown on the product page and confirmed in your order confirmation email. We will send you tracking information as soon as your order ships.

How is it delivered?

Your sauna or cold plunge is delivered by a professional freight carrier directly from the supplier's Australian warehouse. Delivery is to your kerb or garage — it does not include carry-in, assembly, or installation. We recommend having 2–3 people available on delivery day to assist with moving the flat-pack components to your installation location.

What base does it need — concrete, pavers, or a deck?

Your sauna needs a firm, level, waterproof base. Concrete slabs, pavers on compacted base, and structurally sound elevated timber decks all work well. The base must be perfectly level — even a slight slope affects door alignment and long-term structural integrity. We recommend checking with a builder or landscaper if you are unsure about your surface before ordering.

Do you offer installation services?

Professional assembly can be arranged for many of our products and delivery locations through our supplier and installer network. Availability and pricing depend on the selected model, postcode, site access, base preparation and installation conditions.

NORD SAUNAS can coordinate product selection, technical documentation, delivery and, where available, professional assembly. Licensed electrical, plumbing and site-preparation work must be completed separately by appropriately qualified local trades.

Contact us with your postcode and photographs of the proposed location for a delivered and assembled project quotation.

What is your return policy?

Due to the size and nature of these products, returns are assessed case by case. If a product arrives damaged or is not as described, we will work with you and the supplier to arrange a replacement or resolution at no cost to you. For change of mind returns, please contact us within 7 days of delivery. Return freight costs apply and products must be unassembled and in original packaging.
