HUUM Sauna Heater & Controller
Each Atelier garden sauna is powered by a HUUM sauna heater. HUUM is an award winning company renowned for its innovative and elegantly designed sauna heaters, which blend modern aesthetics with traditional sauna experiences. Their stainless steel heaters are distinguished by a high stone capacity, ensuring gentle and long-lasting steam.
The size of the HUUM heater depends on the internal cubic metre area of the sauna and varies from a 4.5Kw Drop 4 (2 Person Sauna) to a 15Kw Hive 15 (12 Person Sauna).
We include the correct amount of genuine HUUM rounded stones with each heater supplied. HUUM emphasizes the use of natural, round sauna stones, such as olivine diabase, to achieve optimal thermal performance and durability.
In addition each garden sauna is supplied with a HUUM UKU internal temperature sensor and sauna controller allowing users to set heating times and temperatures. A UKU WiFi version is available as an optional extra which is compatible with the HUUM mobile app, enabling remote control of the sauna from a smartphone.
Sauna Accessories
As standard, and to enhance the sauna experience, we include:
- Sand Clock – Measures 15-minute intervals to help monitor the recommended bathing time.
- Thermometer – An internal sauna thermometer to ensure optimal comfort.
- Bucket & Ladle – A high-quality bamboo and aluminium sauna bucket and ladle for an authentic sauna experience.
Western Red Cedar Internal Cladding & Bench
Inside our premium quality garden saunas you will find all the walls and ceiling lined with Western Red Cedar.
Western Red Cedar is considered the best choice for the interior of a sauna due to several key properties: Cedar is highly resistant to moisture, rot, and mildew, making it ideal for the humid and hot conditions inside a sauna. It doesn’t warp, crack, or shrink as much as other woods when exposed to fluctuating temperatures. It has a low thermal conductivity, meaning it stays relatively cool to the touch even in high sauna temperatures. This prevents the wood from becoming too hot and uncomfortable for users.
Cedar emits a natural, calming aroma that enhances the sauna experience. The scent also has mild antibacterial and antifungal properties, which help maintain cleanliness. The wood contains natural oils that repel insects and inhibit bacterial growth, reducing maintenance needs. Cedar is a long-lasting wood that can endure years of sauna use without deteriorating. It maintains its structural integrity even with repeated heating and cooling cycles. Unlike some other woods, cedar has a naturally smooth surface with minimal splintering. This makes it ideal for benches and backrests where direct skin contact occurs.
Our saunas also include premium profiled single or twin slatted Western Red Cedar bench.
Glass Door & Panoramic Window
The external sauna door is made of clear safety glass, complete with a cedar frame, roller lock, hinges, seal, and handle, measuring 622mm × 1835mm. Each garden sauna includes a fixed double-glazed panoramic glass window panel. Bespoke panoramic or vertical glass window panels are available upon request.
Ventilation System
Sauna ventilation refers to the system of airflow management in a sauna to ensure fresh air circulation, maintain comfortable oxygen levels, and regulate temperature. Proper ventilation improves the sauna experience by preventing stale air, ensuring even heat distribution, and reducing humidity buildup.
Each individual sauna is supplied with an air intake which is located near the floor, close to the heater which brings fresh air into the sauna. In addition each sauna includes an exhaust vent. The exhaust vent is positioned higher up on the opposite side, allowing warm, stale air to exit.
Traditional Timber frame construction
All our garden saunas manufactured using traditional timber framed walls and floor. The walls are constructed using heavy duty solid 75mm structural graded timber and the floors are constructed from 100mm structural graded timber frames to carry the load of the building. The floor timbers are pressure treated and impregnated with Tanelith E wood preservative.
Fully Insulated
The structural timber walls sections contain 75mm Knauf RS45 thermal acoustic insulation. Knauf is one of the UKs market leaders in insulation and its products are the most thermally efficient and technically advanced insulation products available today. The garden sauna roofs are constructed using a highly insulated trapezoidal roof panel system.
The roof panel is sandwiched with PIR rigid thermal insulation. The highly insulated trapezoidal roof panels span the single pitch, with a fall from front to back. The outside edges of the dark grey roof panels are additionally covered with an aluminium roof edge trim and black woodgrain roof fascia boards.
Breathable Membrane & Heat Reflector
The insulated garden sauna timber walls are externally wrapped in a specialist high performance waterproof breathing membrane. This membrane acts like a one way valve and allows natural moisture to escape out of the garden shed – but prevents moisture from entering the building. Additionally all internal walls are wrapped in a specialist sauna aluminium heat reflector\ moisture barrier.
Our garden saunas additionally incorporate double vented timber walls allowing air to circulate, enabling the structure to breathe. The first vent allows air to circulate between the outer timber cladding and the breathing membrane. The second vent allows air to circulate between the breathing membrane and the insulated walls.
Black Woodgrain Composite External Cladding
Woodgrain composite cladding allow you to effortlessly achieve a wood cladding look on your exterior garden sauna walls. The woodgrain texture gives a natural wood effect. Manufactured using a combination of 60% recycled hardwood fibres and 40% recycled plastic, our woodgrain composite cladding is zero maintenance and insect and rot resistant.
Unlike traditional timber cladding, our woodgrain composite cladding does not require staining, varnishing or sanding throughout its lifespan. As standard we externally clad our garden saunas in black woodgrain composite cladding as this contrasts especially well with the Western Red Cedar integral cladding. However we can offer a range of eight different colours – Redwood, Olive Green, Ivory, Teak, Coffee, Charcoal (Black), Light Grey and Stone Grey.
On Site Installation
All our sauna prices include delivery and full on-site construction by our highly trained professional installation teams. Each garden sauna is expertly installed with minimal disruption, typically within 3-7 working days. Our installation service is available across the UK mainland and includes assembly on either a hard, solid surface or a grass/soil area using concrete pile foundations. From start to finish, we handle the entire project, ensuring a seamless experience.
Unlike other garden sauna providers, you won’t need to supply a base, deal with flat-pack self-assembly, or arrange a crane for unloading. For complete ease and peace of mind, we take care of everything, delivering a fully installed sauna without the hassle.
5 Year Structural Guarantee
For complete peace of mind, all our garden saunas come with a 5-year structural guarantee. This covers design and manufacturing defects, material failure, corrosion, and rot for five years from the date of installation. In addition to our garden sauna guarantee, we also pass on all manufacturers’ warranties for components such as HUUM heaters, controllers, and electrical items.
