    For those who seek timelessness not to flaunt, but to live in.

    We are all really two people: the daily self that comes and goes, and the ideal self that luxuriates in silence and calm. In the Hele Single, the ideal self is invited to emerge: poised and suffused with wonder. Every visit is a gentle reminder that luxury is found in presence, in being fully alive in the moment.

    For the one who revels in architectural elegance and shared rituals. It won design awards, yet its true value is experiential — not merely owning a conversation piece, but being transformed by it. Hele Single evokes a hushed reverence from those who are fortunate enough to discover it.

    Here’s what makes it great

    • 360° Panoramic View with Privacy

      Mirrored glass ensures you see out, but no one sees in, blending your sauna into any landscape.

    • Social Layout

      Circular bench and central heater create a space for connection and conversation.

      All saunas are equipped with a stainless lock and two reliable roller-locks.

    • Effortless Maintenance

      Double-waxed interior and removable platforms make cleaning a breeze.

    • Unmatched heat experience for all bathers

      The round design distributes steam equally between everyone

    Luxury

    Each of the seven seats are formed by converging rays which all point to a centrally placed large stone basket heater. This amount of thermal mass takes longer to heat up, but also provides a subtle and long-lasting steam. The luxury interior in Hele Single is only available with an electric heater.

    During daylight, it is not possible to see inside the sauna. When it’s dark, the interior of the sauna can be partially visible. The ability to perceive the interior through the glass solely relies upon the presence of an illuminating source.

    In Hele Single, our design incorporates LED lights positioned beneath the benches, intentionally obscuring the direct visibility of the light source. This deliberate arrangement contributes to diminished transparency through the glass panel. To further enhance the level of privacy, LED lights have been strategically placed beneath the eaves around the sauna. The light from these LEDs is cast onto the glass surface, inducing a heightened degree of reflectivity.
    With electric heaters we offer the HUUM UKU sauna control systems which are a great way to heat up your sauna with modern technology. You can control it from the local sauna control panel or the HUUM mobile app. To control your sauna remotely we offer two options:

    UKU WiFi control system is an excellent option for saunas in areas with WiFi coverage, such as homes, offices, or accommodations. With this system, you can heat your sauna using the control panel on-site or from your mobile phone, no matter where you are at the moment.

    UKU 4G control system is perfect if your sauna is in an area without Wi-Fi coverage, but you still want to control it from your phone. It’s ideal for cottages or country houses that are not in use all year round. You can heat the sauna from the control panel or your mobile phone, and the system uses mobile data to connect to the HUUM mobile app.

    HUUM app allows you to easily set the start and end time of heating, the target temperature, and check the current temperature of the sauna. Plus, you’ll receive a notification when the sauna is warm and ready to use
    When placing your sauna directly on soil, the ground must be properly prepared to ensure stability and long-term durability.

    Groundwork:

    Remove the top layer of soil and replace it with a well-draining, load-bearing material such as gravel, splinters, or
    sand.

    Foundation Support:

    Place and level concrete tiles horizontally on the load bearing material —each tile should align with the sauna legs (see installation manual) to provide full support and be at least 30x30 cm or 11 13/16" x 11 13/16".

    Ventilation:

    It is essential to maintain proper ventilation beneath the sauna. Sauna legs or skid provide the minimum required clearance and must remain unobstructed at all times.
    Limit vegetation growth underneath and around the sauna to reduce the risk of moisture-related damage.


    The sauna can also be installed on pre-existing hard surfaces such as terraces, rooftops, or paved stone areas. Alternative foundations such as concrete posts or screw pegs may also be used.

    Surface Requirements:

    Ensure that the surface is completely level, load-bearing, and capable of supporting the full weight of the sauna—including the number of users it is designed for. Refer to your chosen model's technical specification section for weight and dimension details.

    Ventilation:

    Even on hard surfaces, adequate airflow beneath the sauna is critical. The existing skid provides the necessary clearance and must not be altered or obstructed.
    Haljas saunas are designed to be used even within extremely cold climates. Our sauna’s performance has been tested at temperatures as low as -25 °C (-13 °F). Our commitment to ensuring robust thermal insulation is reflected in our employment of double-glazed glass panels that are 30 mm thick: 8mm thick glass on the inside and 6mm glass on the outside, and between them there’s a 16mm gap filled with argon gas, a proven insulator. The door is the only single-layer, 8mm thick glass. Each of these glass panels undergoes a tempering process, significantly enhancing their resilience against breakage.
    Generally 3-phase 400V, 16A. To get more information about it, please turn to your local authorized dealer or contact us.
    The final location of the sauna depends on your preferences, surroundings and is largely a matter of taste. The placement should be in accordance with the soil preparation requirements described in our installation manual - this can be provided by your local authorised Haljas retailer. Here are a few examples of the most popular locations:

    ❍ Forest

    ❍ Backyard

    ❍ Terrace

    ❍ Rooftop

    ❍ Balcony

    ❍ Beach

    ❍ By the pool
    Haljas saunas are delivered in a state of near-complete pre-assembly (plug & play). Merely minimal installation procedures are requisite and are expected to be finished within two hours. These tasks encompass the placement of stones in the electric heater and the attachment of the door handle. Detailed instructions pertaining to the unpacking and installation procedures can be found in our installation manual or sought from your local Haljas retailer.
    Suitable temperature is always individual for each person, but we've found that Haljas sauna works best between 65 - 70 degrees celsius. Due to the large glass surface which radiates heat, lower temperatures are felt sufficient. In this temperature range, you will have the most relaxing sauna experience - the ideal level of humidity and light, evenly distributed steam create a pleasant environment where you can take a long sauna session and truly enjoy the experience.

    Try using the sauna at different temperatures to find what is most suitable for you.
    For wood-fired sauna versions, there is a switch inside the sauna. In the case of electrically heated versions, the lighting can be managed either via the Huum controller or through the HUUM mobile application.
    Haljas saunas can be lifted either from beneath with a forklift, or from above, using the four pre-installed mounts on the roof. Hele Nano is the only sauna that does not have mounts, but can be hoisted with straps. Detailed instructions can be found in our installation manual.
    All electrical saunas except Hele Nano are equipped with a mechanical ventilation system, operable directly from the UKU control panel. Activating both lighting and ventilation concurrently is easily achieved with a double-click of the button.

    For an optimal sauna experience, it is advisable to initiate the ventilation system approximately 10 minutes prior to commencing the sauna bath, maintaining its operation throughout the session. Following the sauna session, we recommend leaving the ventilation active for an additional 30 minutes to facilitate the dissipation of excess humidity.

    It’s important to note that all wood-burning heaters are inherently designed to regulate ventilation as needed.
    Water channels have been milled into the flooring. These channels are uniformly directed towards the drainage with an odor trap.

    it is important to establish a level sauna by utilizing the adjustable legs provided. Furthermore, it is recommended to incorporate a 1% decline in the direction of the designated water runway on the roof, thereby facilitating optimal drainage.
    We recommend cleaning the glass at least twice a year. Maintaining a crystal clear visual appearance can be harder outside due to various reasons, for example the combined effects of rain and sunlight (UV radiation), air pollution, such as acid rain, and the presence of springtime pollen, among others. Nevertheless, it’s worth noting that the frequency of cleaning is primarily a matter of personal preference and does not exert any significant influence on the inherent quality of the glass.
    The duration of time spent in a sauna is inherently subjective, as individual preferences vary. Some individuals may enjoy prolonged sauna sessions, while others may prefer shorter visits. It is essential, however, to exercise caution and maintain attentiveness to one’s physical sensations throughout the sauna session.

    It’s important to note that many of the health benefits associated with sauna use are linked to the gradual elevation of body temperature. Achieving this effect is generally more attainable through extended stays in moderate temperatures, as opposed to shorter durations in conditions of extreme heat.
    We’ve chosen high-quality, double-glazed mirror glass that’s 1.18 inches thick to minimize heat loss. This glass combines a 0.31-inch clear layer inside with a 0.24-inch mirrored layer outside, separated by a 0.63-inch space filled with Argon gas. In fact, the thermal efficiency of this glass is comparable to 2.36 inches of solid wood. This means you can look forward to a cozy, efficient sauna session even in the chilliest climates. Our saunas are designed with your comfort in mind, ensuring you can enjoy a warm, soothing experience year-round.
