Reinforced Construction – Certified C24 Timber & Steel Base

At the core of the Primatherma lies certified Scandinavian C24 spruce timber, renowned for its dimensional stability, resistance to deformation, and structural longevity.

What distinguishes Primatherma from smaller models is its reinforced steel floor base, which:

  • Significantly increases load-bearing capacity

  • Enhances overall structural rigidity

  • Ensures stability even on demanding foundations

The steel frame is treated with anti-corrosion protection, guaranteeing durability in challenging weather conditions. This hybrid construction—premium timber combined with engineered steel—positions the Primatherma luxury spacious garden sauna as a robust and long-term investment.

Advanced Insulation – Thermal Comfort Without Compromise

Primatherma has been meticulously engineered for superior thermal efficiency and rapid heat-up performance.

Insulation specifications:

  • Walls: 100 mm rock wool

  • Ceiling: 150 mm rock wool

  • Floor: 100 mm extruded polystyrene (XPS)

This advanced insulation envelope ensures stable high temperatures and energy-efficient operation, even within the sauna’s larger interior volume. The result is optimized heat retention, reduced energy consumption, and consistent comfort throughout every session.

In premium wellness architecture, performance defines true luxury.

Exterior Façade – Natural Premium Elegance

The external cladding is crafted from Scandinavian spruce boards, combining refined aesthetics with high resistance to outdoor conditions.

The clean, modern silhouette emphasizes:

  • Architectural minimalism

  • Natural wood character

  • Seamless integration into contemporary garden landscapes

The Primatherma luxury spacious garden sauna blends understated elegance with commanding presence, elevating the visual value of any property.

Interior – Space, Comfort & Modern Sophistication

Inside, Primatherma offers an expansive and harmonious wellness environment.

The floor is finished with matte ceramic tiles Tubądzin Torano Grey (598 × 598 mm)—highly resistant to moisture and easy to maintain. Natural spruce wall cladding creates warmth and visual cohesion.

In the ceramic tile configuration, the sauna includes a wooden platform for ergonomic balance. When underfloor heating is selected, the platform is removed, providing a seamless heated surface for enhanced comfort.

Every design element has been carefully selected to deliver both durability and a refined sensory experience.

Glazing – Light, Openness & Privacy

Large glazed panels made from tempered, tinted double-glazed glass provide generous natural light while maintaining privacy.

This architectural glazing enhances spatial perception and creates a connection between interior relaxation and the surrounding landscape—without compromising discretion.

  • Wind stability

  • Long-term weather protection

Alder Wood Benches & Backrests

The interior is completed with ergonomic benches and backrests crafted from premium alder wood—an ideal material for sauna environments due to:

Comfort during extended sessions is ensured by thoughtful bench geometry and material quality.
