Frequently asked questions

How do I order a sauna?

Ordering your Sauna online is simple and completely transparent:

  2. Secure Checkout: Click "Add to Cart" and proceed to our secure checkout. We accept all major credit cards, Apple Pay, Google Pay, and Direct Bank Transfers.
  3. Production Queue: Once your order is placed, you will receive an instant email confirmation. Our team then prepares your made-to-order kit, and our freight partners will contact you to coordinate delivery as it nears completion.
Where is the best place to install my outdoor sauna?

The ideal location for your sauna is any flat, solid, well-drained outdoor surface, such as a concrete slab, paved courtyard, or reinforced timber deck. Do not install the sauna directly on grass or bare dirt, as moisture can damage the timber base over time. For the best experience, place your cabin in a private area of your yard that has easy access to both your home's electrical supply (for hardwiring the heater) and a shower or pool for cool-downs.
What are your current lead times for delivery?

Because each sauna is prepared to match the specific choices you select in our online builder, our average delivery lead time is currently 6-12 weeks. Lead times can vary depending on your location and seasonal demand.
How do your saunas work?

We specialise in authentic traditional saunas that combine modern engineering with time-tested wellness practices. The system relies on three key elements:

  • The Harvia Heater: Electric elements heat a basket of specialised volcanic stones, warming the ambient air inside the cabin to a deeply relaxing 70–90°C.
  • The Thermal Timber: Whether you select our Nordic Spruce or Red Cedar, the precision-fit interlocking panels act as a heavy-duty insulator, trapping the heat perfectly inside the room.
  • The Steam: Because these are traditional rock heaters, you can pour water over the stones. This creates a cloud of refreshing steam, temporarily raising the humidity and intensifying the cardiovascular and detoxifying benefits.
How are your saunas delivered to my home?

All Saunas Online kits are delivered via flatbed or tail-lift trucks to ensure maximum safety for the timber and glass components.

Your delivery will be booked in advance by our carrier and dropped off at the curbside or easily accessible driveway entrance of your property. Please ensure your delivery address has clear, unobstructed access for a large delivery vehicle. Because the kit arrives flat-packed, you don't need heavy machinery to move it, two people can easily open the crate and hand-carry the modular panels directly to the backyard or deck where you plan to build it.
