Reinforced Construction – Stability, Scale & Prestige

At the core of the Therma Suprema lies certified Scandinavian C24 spruce timber, renowned for its structural stability, resistance to deformation, and long-term durability. This high-grade timber forms the foundation of a sauna engineered for intensive, year-round use.

The entire structure is supported by a reinforced steel floor base designed to:

  • Increase overall load-bearing capacity

  • Enhance rigidity and dimensional stability

  • Ensure safe performance in large-format configurations

The steel frame is protected with advanced anti-corrosion treatment, guaranteeing durability even in challenging weather conditions. This combination of engineered steel and premium timber construction positions the Therma Suprema flagship luxury garden sauna as a long-term investment in both property value and personal wellbeing.

Advanced Thermal Insulation – High Performance Without Compromise

Therma Suprema has been meticulously developed for exceptional thermal efficiency and rapid interior heating.

Insulation specifications:

  • Walls: 100 mm rock wool

  • Ceiling: 150 mm rock wool

  • Floor: 100 mm extruded polystyrene (XPS)

This advanced insulation system ensures stable temperature retention and energy-efficient operation, even within the generous interior volume. The sauna maintains consistent heat levels while minimizing energy consumption—an essential feature for modern luxury wellness architecture.

Performance and sustainability coexist seamlessly in the Therma Suprema flagship luxury garden sauna.

Premium Architectural Design – A New Definition of Form

Therma Suprema introduces a more expressive and prestigious design language compared to earlier models. Its increased width enhances both spatial comfort and architectural impact, creating a bold yet elegant silhouette that integrates perfectly with contemporary garden design.

The exterior façade is crafted from Scandinavian spruce cladding, combining natural warmth with durability against environmental exposure. Clean lines, balanced proportions, and refined detailing give the structure a monumental presence without compromising elegance.

This is architecture designed not only to function—but to impress.

Interior – Space, Light & Elevated Comfort

Inside, Therma Suprema offers an expansive and harmonious wellness environment.

The floor is finished with matte ceramic tiles Tubądzin Torano Grey (598 × 598 mm), selected for their moisture resistance, durability, and ease of maintenance. Natural spruce wall cladding enhances warmth and creates a tranquil atmosphere conducive to deep relaxation.

In the tiled configuration, the sauna includes a wooden platform for ergonomic comfort. When underfloor heating is selected, the platform is removed to provide a seamless heated surface—combining modern comfort with aesthetic clarity.

Every interior detail of the Therma Suprema flagship luxury garden sauna reflects Caldori’s commitment to engineering precision and sensory refinement.

Glazing – Light with Discretion

Large glazing panels made from tempered, tinted double-glazed glass allow generous natural light to enter the interior while ensuring complete privacy.

This balance between openness and discretion enhances spatial perception and connects the sauna experience with the surrounding landscape—without compromising comfort.

Premium Exterior Doors

Therma Suprema is equipped with black aluminum exterior doors featuring double reflex glazing. These doors emphasize the flagship character of the model while providing durability, thermal insulation, and enhanced security.

The contrast between natural timber and refined aluminum elements reinforces the sophisticated architectural identity.

Roof System – Durability Meets Modern Form

The roof is finished with standing seam metal cladding, a solution that ensures:

  • Resistance to heavy rain and snow

  • Wind durability

  • Long-term structural protection

  • Contemporary architectural appeal

This roofing system perfectly complements the bold, modern lines of the Imperia design language.

Alder Wood Benches & Backrests

The sauna interior is completed with ergonomically designed benches and backrests crafted from premium alder wood. Alder is highly valued in sauna environments for:

  • Low thermal conductivity

  • Smooth, comfortable surface texture

  • Durability in high temperatures

  • Natural aesthetic warmth

These elements ensure comfort during extended sessions while maintaining structural integrity over time.

LED Lighting – A Flagship Standard

Lighting within the Therma Suprema flagship luxury garden sauna is an integral design component that elevates the entire outdoor wellness environment.
