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.
