Her Majesty, Eterna

The Eterna sauna embodies the traditions of Finland, where every element is crafted with meticulous attention to detail to ensure harmony, energy efficiency, and comfort. The dry heat of the sauna, reaching 80–110°C with low humidity (10–25%), helps you relax and recharge. Inside, convenient benches are installed at different levels, while the Finnish electric Harvia stove, equipped with a stone compartment, evenly distributes the heat. Gentle steam is created when water touches the hot stones, forming a soothing and beneficial atmosphere.

The core of the sauna’s construction is a 180 mm thick wall, where every layer plays a crucial role in retaining heat. High-quality insulation material is used and covered from the inside with a vapor barrier foil to ensure airtightness. Even the spots where the foil is fastened are carefully sealed, which increases the energy efficiency of the structure by 25–30%. The exterior cladding is made of wood—be it pine or cedar, the thickness remains the same. The interior walls are finished with Canadian cedar, chosen for its optimal thickness to preserve heat and ensure durability. This wood is not only practical but also releases a unique fragrance that fills the space with natural comfort.

The color of the exterior stain is up to the owner’s choice. We are confident that everyone can find a shade that reflects their style and preferences. From classic natural tones to rich modern colors—the decision is entirely up to the future owner. The color, however, does not affect the sauna’s performance but rather highlights its individuality.

The Eterna sauna is more than just a place to unwind. It is a space where traditions and modern technologies merge. The sauna provides not only comfort and warmth but also becomes a true sanctuary for rejuvenation. Every detail, from the interior cladding to the insulation, is designed with one goal—to make every moment in the sauna a true pleasure.
