Traditional Sauna For Four
Have a question? We’ve got you.Contact Us
Did a fair bit of looking around before buying and this sauna has been unreal. Heats up quick and feels really solid. Looks great in the space and just works how you want it to. Been using it a few times a week and wouldn’t change a thing.
Was great to finally find a sauna that actually fit into our space. We had a spot picked out for ages but couldn’t find anything that looked nice enough to put there. This one just worked straight away and looks really good in the setting.
Sits perfectly near the pool and looks unreal at night when it’s all lit up. Really adds to the area and doesn’t feel out of place at all. We’ve had heaps of comments on how good it looks and it’s been awesome to use as well.
Absolutely love this thing. We use it most nights now and it’s become part of our routine. Feel so relaxed getting into bed afterwards and sleep has been noticeably better. One of the best things we’ve added to the house.
Love using it in the morning. Helps me feel more awake and loosen up before the day starts. Head feels clearer and I’m way more switched on after. Honestly hard to beat once you get used to it.

Arrival of Your Sauna
Your sauna will arrive in protective cartons, usually around 5 to 8 cartons per sauna. This makes it easier to move each section into position before assembly.
Installation
Swell saunas are made for DIY setup, with pre cut components and clear, step by step instructions. Most customers can move the cartons into position and complete the assembly with two people over a few hours. A licensed electrician is still required to connect the heater. If you would prefer a hands off setup, we have a team available Australia-wide to handle the assembly for an extra cost. Please reach out and we can help arrange it.
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
Warranty
Designed for all weather indoor and outdoor conditions and backed by a 5 year warranty
The Swell White Retreat 4 uses a premium Harvia Spirit 6kW traditional sauna heater and requires a dedicated 25A single-phase circuit installed by a licensed electrician. We intentionally oversize the heater for reliability, strong performance and fast heat-up times, while keeping the sauna below the larger three-phase requirements that are not universal for Australian homes.
No. The Retreat 4 does not require three-phase power. It is designed so it can be installed in standard Australian homes with the correct dedicated single-phase circuit added by a licensed electrician.
The Retreat 4 is a traditional Finnish-style sauna, not an infrared sauna. It uses a Harvia heater and sauna stones to create full-room heat and steam when water is poured over the stones.
The sauna simply needs a level, compacted surface. Concrete, pavers, decking or a prepared compacted area can all work well. We recommend avoiding direct placement on grass because grass can hold moisture under the base.
The Retreat 4 body measures 188.5cm wide x 150cm deep, with a sloped roof height of 210cm at the front and 200cm at the rear. The roof is larger than the body, measuring 228.5cm wide x 171cm deep, with approximately 20cm of overhang from the sauna body.
