Compare Swell Cedar Cube 2 and Cube 4 Saunas

Two solid-cedar outdoor saunas. Two different ways to use the space. Choose Cube 2 for a compact solo or couple routine, or Cube 4 when you want more width and room to share.

Cube 2: a compact sauna for one or two

The Swell Cedar Cube 2 measures 136cm W × 135cm D × 210cm H externally, with an internal space of 122cm W × 121cm D × 187cm H. It is designed for one or two people. Base and Smart Heat packages use a 4.5kW Harvia The Wall heater; Pro uses a 6kW Harvia Spirit. Check the selected package for its exact controls and inclusions.

Cube 4: more room for shared sessions

The Swell Cedar Cube 4 measures 193cm W × 134cm D × 210cm H externally and is designed for up to four people. Its wider layout gives you more flexibility when adults share a session. The available Harvia packages use 6kW heaters, with different heater and control combinations.

What both Cubes have in common

Both use 38mm solid Japanese cedar, bitumen roof shingles, tempered glass doors, timber benches and lighting behind the backrest. Both are specified for indoor or outdoor installation. Their five-year residential cabin warranty is subject to terms; heater and electrical components have separate coverage. Their natural timber finish needs care; oiling the exterior helps retain the rich cedar colour.

Product details and settings vary with the selected heater package.

Measure more than the cabin

Cabin dimensions are not a minimum clear-space specification. Check the manuals for installation, ventilation and heater clearances, and allow room for door opening and maintenance. A narrow garden may fit the footprint while leaving too little space to use or service it comfortably.

Assembly and power: the same planning discipline

Both models arrive in protective crates with cartons inside and have step-by-step assembly videos. You can choose DIY assembly or paid support from an Australia-wide installation team. Both require a dedicated supply, with a licensed electrician sizing and connecting it for the exact heater. Do not assume every Cube 2 package has identical electrical requirements.
