Eira 240 Signature Sauna: The Pinnacle of Modern Wellness

Intelligent Heating: The 9kW HUUM System Experience the perfect synergy of organic aesthetics and smart innovation. At the heart of the Eira 240 is the acclaimed 9kW HUUM heater, a triumph of Estonian engineering. Its distinct, nature-inspired “drop” basket isn’t merely a design statement—it is engineered to hold an immense volume of stones, delivering rapid heat-up times and a deeply enveloping, authentic steam (löyly).

  • Pinpoint Climate Control: Seamlessly drive and sustain ambient temperatures up to 110°C with absolute precision.

  • Flexible Connectivity: * Manual Touch: Intuitive, tactile controls located right at your sauna.

    • Wi-Fi Integration: Pre-heat your luxury garden retreat directly from your smartphone using the HUUM app, so it’s ready the moment you step outside.


      Architectural Elegance: Shou Sugi Ban & The Seamless Cube
  • Charred Timber Cladding: Wrapped in 19mm timber treated with the ancient Japanese Shou Sugi Ban technique , the Eira 240 boasts a striking, deep-charcoal facade. This natural burning process hardens the wood, offering exceptional resistance to moisture, rot, and insects, resulting in an eco-friendly, ultra-low-maintenance exterior.

  • Floor-to-Ceiling Glass: The iconic “Cube” design is anchored by a stunning panoramic glass front. Customize your sanctuary with Mirrored Glass for absolute privacy and a reflective aesthetic that blends into your garden, or Smoked Glass for a sleek, contemporary shadow-box effect.

  • Invisible Weatherproofing: Beneath its minimalist flat-roof profile lies a highly engineered pitched roof system. Built from durable marine plywood and sealed with a heavy-duty rubber membrane, it discreetly channels rainwater to a concealed rear drainage point.

An Unshakable Foundation Unlike conventional wooden saunas that are prone to ground rot over time, the Eira 240 Signature Sauna is constructed on a heavy-duty, galvanized steel chassis finished in a sleek black powder coat.

  • Adaptable Levelling: Industrial-grade adjustable feet ensure a level, rock-solid installation, even on sloped or uneven garden terrain.

  • Built to Travel: Because the core framework relies on rigid steel rather than soft timber, your sauna retains its structural integrity. If you ever move homes, your wellness sanctuary can easily move with you.

Ergonomic Comfort & Premium Thermo-Wood

  • Thermo Aspen Interior: The walls and benches are crafted from flawless, knot-free Grade A Thermo Aspen. Thermally modified at intense temperatures, this wood features drastically reduced moisture content and superior dimensional stability, making it uniquely equipped for the extreme sauna climate. The treatment also brings out a rich, warm tone and a velvety-smooth finish that remains highly comfortable against the skin.

  • Oversized Lounging: Designed for ultimate relaxation, the extra-wide 600mm benches provide plenty of depth, allowing you to recline fully and securely.

  • Resilient Flooring: We use rugged Thermo Pine for the deck, specifically chosen to withstand heavy footfall and high humidity year after year.

  • Ambient Illumination: We’ve designed a glare-free visual experience. Indirect LED lighting is seamlessly integrated beneath the top bench and behind the backrests, washing the cabin in a soothing, atmospheric glow.

Next-Generation Thermal Efficiency: FF-PIR Insulation To ensure peak performance, the Eira 240 is lined with highly advanced 30mm Finnfoam FF-PIR panels featuring an aluminium laminate face—a massive upgrade over standard fiberglass.

  • Ultra-Fast Heating: This high-spec thermal barrier traps thermal energy, allowing your sauna to hit target temperatures using a fraction of the time and electricity.

  • Airtight Vapor Seal: The reflective aluminium facing, combined with polyurethane-sealed joints, creates a flawless “thermos” effect, actively protecting the internal structure from moisture ingress.

Why Choose the Eira 240 Signature? Committing to regular sessions in the Eira 240 is an investment in your long-term vitality. The science-backed benefits of home heat therapy include:

  • Cardiovascular Conditioning: Elevates the heart rate and enhances blood circulation safely and naturally.

  • Cellular Detoxification: Deep, passive sweating flushes out impurities and leaves skin glowing.

  • Accelerated Recovery: Melts away joint stiffness and soothes sore muscles after a long day or heavy workout.

  • Mental Reset: Drastically lowers cortisol (stress) levels, paving the way for improved focus and deeper, more restorative sleep.
