The Saunum AirCube One is a true masterpiece of sleek design and expert craftsmanship. Its modern, minimalist structure seamlessly blends into garden and poolside environments, creating a harmonious outdoor sanctuary. With meticulous attention to detail and the use of top-quality materials, this saunahouse excels in both durability and luxury. Whether your aim is to relax after a long day or entertain friends and family, AirCube One offers an unparalleled retreat of sophistication and comfort, making it the centerpiece of your outdoor space.

Highly Customisable

As can be seen from the raft of options above, you can tailor the AirCube to suit you or your clients requirements.

Exterior Finish - Black, Anthracite or Light Grey

The Saunum AirCube One offers a choice of exterior finishes in Black (as standard), Anthracite, or Light Grey. This allows for seamless integration into various outdoor settings, ensuring the sauna complements your garden or poolside with its elegant design. Each option maintains the sauna's modern appeal, catering to different stylistic preferences.

Glass Colour - Clear, Bronze or Grey

This selection allows for further personalisation of the sauna, catering to different preferences for light and privacy. Clear glass maximises natural light and visibility, bronze offers a warmer, subtle tint, while grey provides a sleek, contemporary look with added privacy. Each option enhances the overall aesthetic of the sauna while aligning with individual style and functional needs.

Interior Cladding and Floor - Alder or Thermo-Aspen

The Saunum AirCube One comes standard with an Alder wood interior cladding, celebrated for its soothing and warm qualities. For those looking for an upgrade, the option of Thermo-Aspen wood is available. Thermo-Aspen is valued for its enhanced durability and excellent resistance to temperature variations, making it an ideal choice for frequent sauna use. Its fine texture and subtle aroma add to the luxurious sauna experience, while its thermal treatment process boosts its longevity and reduces the likelihood of warping or decay, ensuring a pristine and long-lasting sauna environment.

Bench/Backrest - I Shaped or L Shaped - Alder or Thermo-Aspen Wood

The AirCube One offers a choice of bench and backrest designs, available in both I-Shaped and L-Shaped configurations, catering to different space and comfort needs. The standard option includes the I-Shaped bench, elegantly crafted in Alder wood. For those who prefer a different layout or wood type, the sauna also offers the L-Shaped bench as an alternative, providing additional seating space and comfort. Both bench styles can be customised in Thermo-Aspen wood, a premium option known for its durability and resistance to temperature changes, enhancing the sauna's longevity and aesthetic appeal.

A Symphony of Light and Sound

The AirCube One is equipped with both indoor and outdoor LED lights, creating an atmosphere that shifts to match your mood. As the daylight fades, the dimmable lights (optional extra) cast a soft glow, enhancing the natural beauty of the Alder cladding. For the audiophiles, Bluetooth speakers are available as an optional extra to be seamlessly integrated, allowing you to immerse yourself in the soundscape of your choice, completing the multi-sensory experience.

Technical Sophistication

The Saunum AirCube One is not just about aesthetics and comfort; it's also built with technical precision. From the self-closing door with a natural oak and stainless steel handle to the insulated walls ensuring efficient heat retention, every detail is designed with your convenience in mind.


Your wellness journey is unique, and so should be your sauna. Saunum AirCube One is fully customisable, with additional features to tailor your experience. Choose from various exterior finishes, glass tones, and interior claddings to match your personal style.

The electrical supply required will depend on the kW rating of your chosen heater. We strongly recommend consulting with an electrician prior to any installation.

Typically, a 'dedicated' supply is utilised, similar to those for electric showers or cookers.

To calculate Amps:

  • Divide the Watts (e.g., 6000 for a 6kW heater) by the Volts (commonly 230)
  • Therefore, the Amps for a 6kW heater approximately equal 25

This small table covers domestic sauna heaters:

  • 2.3kW = approximately 10 Amps
  • 3.0kW = 13 Amps
  • 3.6kW = 15 Amps
  • 4.5kW = 19 Amps
  • 6.0kW = 26 Amps
  • 8.0kW = 35 Amps
  • Heaters above 8.0 kW typically require a Three-Phase (commercial-type) supply.

We strongly advise the use of a fully qualified electrician, compliant with all Government Regulations.

The Sauna of the Next Century

How Does Saunums 5-in-1 Patented Technology Work?

Saunum’s patented air-blending system traps the scorching steam, that rises under the ceiling of the sauna room, mixes it with cooler air on the floor surface, and directs the soft steam back evenly. This ensures a more even temperature of the steam, and the oxygen-enriched steam makes it easier to breathe. Water can be thrown more often to produce more steam, making the sauna air more humid, and ensuring more intense sweat. With Saunum’s patented method of enriching the air with salt ions, the salt ions from the natural salt spheres added to the sauna climate device are infused into the circulating air to reach the skin and respiratory tract. An even more relaxing sauna experience is created with the help of the aroma system, which mixes sauna oil aromas with the steam. It is a healthy alternative to burning aromatic oil on hot stones.

Saunum FAQ's

Can these saunas be delivered flat pack and assembled on site?

No, all Saunum saunas are delivered fully assembled. This is to ensure the integrity of the structure and to prevent any draughts or openings that could lead to damage.

Do I need a crane?

This will depend on the location that you wish to place your sauna. If there is sufficient access, the sauna can be positioned with a fork lift.

If I do need a crane, can you organise this for me?

We deliver the sauna to your location free of charge, however, the cost of a crane will vary significantly depending on the site. We advise that you organise your own crane/HIAB with a local contractor. If you wish, we can organise this for you, but it will always be cheaper to organise it yourself.

Why do the saunas not include a heater in the price?

There are many different specifications of Saunum heaters that cater for different budgets. Some customers already have a heater and only want the structure.
