Thickness and Strength

At 40mm, the staves provide one of the thickest walls you’ll ever see in a Barrel Sauna. These supremely thick walls provide unparalleled insulation, stability, and a barrier from outside noise.

SDS Australia is proud to source timber from Thermory, with their commitment to environmental sustainability. They aim to find balanced solutions for smart wood production that reduce the environmental impact.

Responsible wood sourcing

Thermory carefully monitors where the wood comes from. They only source the best quality wood from sustainably managed forests around the world. This helps reduce the negative impact of deforestation.

Watch Our Easy Assembly Process

Your Thermo Barrel Sauna comes with pre-cut and pre-milled staves and cradles, so there’s no cutting necessary.

You have two options for assembly:

DIY Installation

Easily assemble your sauna yourself with our detailed instructions and pre-cut materials.

Professional Installation

Let our experts handle the installation for you, ensuring everything is perfectly set in place.

We recently purchased a barrel sauna for our commercial mobile sauna venture, and we are thrilled with the high-quality sauna from SDS Australia.

After conducting extensive research on barrel saunas in the Australian market, we found that this product stood out in terms of design, quality, and affordability.

The support we have received has been excellent, and we highly recommend both the company and the product. Thank you, guys!
