Outdoor Saunas

In the UK's damp climate, standard softwoods can warp or decay. Our collection utilizes three "super-timbers" engineered for maximum longevity and performance:

• Thermowood: This is Nordic timber that has been heat-treated (typically at 180°C–212°C) to alter its cellular structure. This process removes resins and moisture, making the wood exceptionally stable, rot-resistant, and an incredible thermal insulator.
• Shou Sugi Ban (Charred Timber): An ancient Japanese technique where the external timber is charred by flame to create a carbonised layer. This jet-black finish is naturally resistant to UV, insects, and moisture. It is virtually maintenance-free and creates a striking, modern aesthetic.
• Thermo Alder: Often used for internal benching, Thermo Alder undergoes a similar heat-treatment to Thermowood. It results in a smooth, knot-free timber with a rich, dark tone that remains comfortable to the touch and releases a pleasant, subtle aroma during use.
  
  

Yes. While many of our products arrive as precision-engineered flat-pack kits for DIY assembly, we also provide a Professional Installation Service.

• The Benefit: Our expert carpenters ensure the structure is perfectly level and weather-sealed, which is critical for the long-term health of the timber.
• Extended Warranty: Professional installation typically extends your structural warranty from 1 year to 2 years, providing total peace of mind for your investment.

A solid, level foundation is essential to prevent ground moisture from affecting the timber. We recommend:

• Concrete Slab: The most stable and permanent option, ideal for larger 6–10 person units.
• Paving Slabs: A versatile and cost-effective choice for most garden settings.
• Timber Decking: Provides excellent natural airflow beneath the structure, though it must be reinforced to support the weight of the sauna and occupants.

Please note: The foundation must be able to withstand the weight of the building plus the maximum capacity of occupants. 

Electrical needs vary based on the heater type and sauna size:

• Infrared & Compact Models: Some are "Plug and Play," requiring only a standard 13-Amp outdoor socket.
• Traditional Electric Saunas: Most 4–6 person models require a dedicated 32-Amp or 40-Amp supply with a rotary isolator.
• Compliance: All final electrical connections must be commissioned by a qualified Part P electrician to meet UK safety standards.

Please Note: It is the customer's responsibility to consult a qualified electrician to assess and install the suitable electrical requirements to the heater's specification.

Because we use Thermowood and Thermo Alder, our saunas offer approximately 25% better thermal insulation than untreated wood. This means they heat up faster and retain heat longer. On a standard UK energy tariff, a one-hour session typically costs between £1.00 and £2.00, making it a highly cost-effective daily wellness ritual.

Our materials are chosen specifically for their weather resistance.

• Thermowood and Shou Sugi Ban are dimensionally stable, meaning they won't shrink or swell significantly during seasonal shifts.
• Maintenance: While Shou Sugi Ban is virtually maintenance-free, we recommend applying a UV-protective oil to natural Thermowood every 2 years to maintain its rich amber colour. Without oil, it will eventually weather to a beautiful, natural silvery-grey.
