Arrival of Your Sauna

Your sauna will arrive flat packed in a secure crate, ready for assembly

Installation

Swell Saunas are delivered with pre cut components and clear, step by step instructions, allowing most customers to handle the setup themselves. All that is required is a flat, stable surface such as concrete or decking, and a licensed electrician to connect the heater

For those who prefer a hands off approach, we offer an installation service across Australia that can manage delivery, assembly and final clean up so the sauna is ready to use sooner

Maintenance

Cedar naturally resists moisture and outdoor conditions, developing a silver grey colour over time while maintaining its strength. To keep the timber looking rich, the exterior can be oiled annually with a breathable wood oil such as Linseed or Feast Watson. Light sanding can be used to refresh the surface

General care is simple. Wipe surfaces as needed, keep the interior free from debris, and check the stones occasionally to ensure everything performing well

Certified Safe

Meets strict Australian Standards for safety, durability, and performance

Cost to Run

A 6kW heater keeps running costs low with a 30 minute session costing around $0.90

    Worth Every Consideration

    We spent months researching before committing to a sauna. We looked at countless brands, compared specifications, read reviews, and even visited a few suppliers in person. Design was just as important to us as performance, and time and again we kept coming back to Swell. The Eco 4 was, without question, the best looking option we found.

    Ordering online for something of this size required a degree of trust, but the Eco 4 did not disappoint. When it arrived and was installed, it looked even better in person. The red cedar is beautiful, and the build quality feels substantial. reaches a proper temperature, and retains heat exceptionally well.

    After months of consideration, we are very glad we chose Swell!!

    Stoked with it!

    Wasn’t sure what to expect ordering something this big online, but honestly it’s unreal. The Eco 4 looks insane in the backyard. The cedar smells amazing when it heats up and it gets seriously hot. Build feels solid, nothing flimsy about it. We’ve been in it nearly every night since it went in. Absolutely wrapped with it.
