Ashcroft: 4 Person Sauna + Primal Tub

Absolutely. All timber used in our saunas undergoes a thermal modification process that dramatically improves its resistance to moisture, warping. This increases dimensional stability, reduces water absorption, and improves resistance to rot and insects.

Every sauna also comes with weatherproof bitumen shingles on the roof, working much like the tiles on your house to protect against direct rainfall and sun.

The chiller runs on standard 240V power, so you can plug it straight into a regular power socket. No electrician needed for the chiller.

Our saunas are designed to be low maintenance but like anything, a little care goes a long way toward keeping it looking and performing its best for decades.

Interior: When you first install your sauna, we recommend treating the interior benches with paraffin oil. It penetrates the timber to prevent it from drying out and cracking under repeated heat cycles, keeping the wood from absorbing sweat and moisture over time. This also makes the surface easier to wipe down and keep clean, we recommend reapplying 12 months. 

Exterior: For the outside, use a quality penetrating oil designed for exterior timber. Brands like Cutek, Intergrain, or Osmo UV Protection Oil all work well. These oils soak deep into the wood, protect against moisture and UV damage, and allow the timber to breathe naturally. They also come in tintable options if you want to add some colour while keeping that natural timber look. We recommend reapplying every 6–12 months depending on your climate and exposure.

After each session: Once you're done, leave the heater running for around 30 minutes with the door closed to dry out any residual moisture inside the sauna. Then open the door and let it air out for another 30 minutes before closing it up. Give the benches a quick wipe down and remove any towels or damp items. 

Absolutely, our saunas are designed for straightforward DIY assembly and most customers find it a pretty enjoyable project. Everything arrives clearly labelled with detailed instructions to guide you through the process.

If you'd prefer to have it professionally installed, we have a network of qualified installers across Australia who can take care of it for you. Just reach out to our team and we'll point you in the right direction.

Yes, your heater needs to be hardwired directly to your home's switchboard by a licensed electrician. It cannot simply be plugged in. The electrician will run a dedicated cable straight from your switchboard to the heater, similar to how an oven or cooktop is wired in. We have a network of electricians across Australia and can recommend one in your local area if needed.

Yes, but it's costly. If you start with the base Harvia Wall SW and later want to upgrade, you can't simply add a control panel as the SW doesn't support one. You'd need to replace the entire heater with the Harvia Wall SWE and then install the control panel. Choose the right heater from the start and save yourself the hassle and expense.

Sauna: A typical two-hour session costs around $2.15 – $2.80 using average Australian electricity rates.

Ice Bath: Daily cost of $0.50c, running the chiller for the average 8-12 hours.

We will bring the crate onto your property, typically into your garage or around the side of the house wherever access permits.
