Electrical requirements: All packages must be hardwired by a licensed electrician. The Base package requires a 32 A circuit for the heater and a separate 10 A circuit for lighting. Smart Heat and Pro use one 32 A circuit for the heater and lighting.

Your electrician must verify the supplied heater and controller models, circuit ratings and installation requirements against the manufacturer’s instructions and applicable electrical standards before installation.

Installation support, Australia-wide.

We work with installation partners across Australia. At-home installation for the Cube 4 typically costs $990, excluding electrical works. All electrical work must be completed by a licensed electrician.

Please contact our team to confirm installation availability and pricing for your home. You’ll receive our installation team’s contact details once you’ve made a purchase or paid a deposit.

Arrival of Your Sauna

Your sauna will arrive in a protective crate with cartons packed inside the crate. This keeps the sauna protected during freight while still making each section easier to move 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 and sauna sections from the crate 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 bands occasionally to ensure everything remains secure and 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

CUBE 4 FAQ

Frequently Asked Questions

Answers to the most common questions about power, installation, delivery and daily use for the Swell Cedar Cube 4 outdoor traditional sauna.

The Swell Cedar Cube 4 uses a premium Harvia The Wall 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 simple to install in standard Australian homes.

No. The Cube 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 Cube 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 Cube 4 external dimensions are 193cm width (left to right), 134cm depth (front to back), and 210cm height. The upper bench is 55cm deep, the lower bench is 75cm deep, and the lower bench extends 23cm further forward than the upper bench.

The Cube 4 is dispatched from our Melbourne warehouse in a protective crate with cartons packed inside the crate. Once your order is on the way, you will receive tracking details so you can follow the delivery and plan around its arrival.

The Cube 4 is made for DIY setup, with pre cut components and clear, step by step instructions. Most customers can move the cartons and sauna sections from the crate into position and complete the assembly with two people over a few hours. 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. A licensed electrician is still required to connect the heater.

The Cube 4 heats to 80°C in around 20 minutes and reaches 90–100°C+ with extended use depending on conditions. It uses a premium Harvia The Wall 6kW heater, intentionally oversized for reliable performance and strong traditional heat in a 1–4 person outdoor sauna.

The Swell Cedar Cube 4 is designed for up to 4 people, making it ideal for families, couples, compact outdoor spaces and daily recovery at home.

The Swell Cedar Cube 4 includes a 5-year warranty for long-term confidence. It is built with premium materials and designed for Australian outdoor conditions.

    8pm Most Days

    Didn’t realise how much we’d actually use it. I normally jump in around 8pm once the kids are in bed and it’s become a bit of a routine now. Takes about 20 mins to heat up and I’m usually in there for 15-20. Have noticed the difference in my sleep

    Gets hot fast

    Really impressed with the quality when it arrived. Took us most of a Saturday to put together but everything lined up nicely and the finished sauna looks unreal.

    Heat up time has honestly impressed me. Gets to 80 degrees in under 20 minutes and holds the heat really well.
