Versatile Spa Settings

The Saunum Spa Session Heater offers an unrivalled sauna experience, allowing you to enjoy various spa settings: from a classic Nordic sauna to a salt ion-enriched steam bath, a humid steam-rich sauna, a mild relaxation sauna, or an aromatic sauna. Each setting is designed to cater to your wellness needs, providing health benefits like improved respiratory function and intense relaxation.

Durable and Stylish Design

Crafted with Magnelis® and stainless steel, this timeless, classic heater design is not just a visually appealing addition to your home but also a durable and energy-efficient choice. It boasts a dual-level stone basket for prolonged heat retention and features corrosion-resistant heating elements for long-lasting performance. Plus, with the steam guidance positioner, you can easily control the distribution of steam to your preference.

Customisable Comfort

The Saunum Spa Session Heater is versatile and can be installed alongside a wall or in a corner of the sauna room. It's designed to heat the sauna room to temperatures ranging from 40 to 90 °C while maintaining a balanced climate, offering you a range of experiences from intense heat to a gentle, humid environment.

Enhance your sauna experience with the Leil control unit. This user-friendly interface allows you to easily control the heater and adjust the climate settings, providing a convenient way to customise your sauna sessions.

Embrace the therapeutic benefits of salt therapy with the patented method of enriching the air with salt ions. This feature infuses salt ions from natural salt spheres into the circulating air, reaching your skin and respiratory tract. It's especially beneficial for respiratory conditions, offering decongestant properties and antimicrobial benefits.

Health-Enhancing Features

The Saunum Spa Session Heater also incorporates an aromatherapy system. By mixing sauna essential oil aromas within the steam, it adds an extra layer of sensory pleasure to your sauna experience, making it a healthy alternative to burning aromatic oil on the hot stones.

    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.
