Heat that goes deep—the Savne Štrus Termo Pure Indoor Sauna heat-treated

When the door closes and the scent of heat-treated wood fills the room, a ritual begins that brings body and mind into balance. The Savne Štrus Termo Pure Indoor Sauna heat-treated Indoor Sauna combines Slovenian craftsmanship with a distinctive modern design aesthetic. Dark, velvety-shimmering aspen slats, interspersed with fine black lines, create an atmosphere that exudes tranquility and brings clarity.

What makes the Savne Štrus Termo Pure Indoor Sauna heat-treated Indoor Sauna so special

The Termo Pure collection is the heat-treated premium line from the Slovenian manufacturer Savne Štrus and includes eight distinct models—ranging from the compact single cabin to the spacious corner sauna for up to eight Persons. Each model is crafted from thermally modified Nordic aspen, which undergoes controlled heat treatment between 180 and 230 °C to achieve its characteristic dark color, reduced thermal conductivity, and exceptional dimensional stability. From the single-story Termo Pure I for tight spaces to the Termo Pure VIII with a sloped ceiling, the right solution can be configured for nearly any room layout. Whether Finnish, BIO, infrared, or hybrid—the Savne Štrus Termo Pure Heat-Treated Indoor Sauna adapts to your personal sauna experience.

Thermally treated aspen and sleek black lines—the material of the Savne Štrus Termo Pure Indoor Sauna

Solid slats with a profile of 21 × 90 mm form the visual and structural backbone of the entire cabin—from the wall paneling to the ceiling and the glass frame. Precise black design lines run between the slats, lending the interior a rhythmic depth and a distinctive character. The benches are made of the same thermally treated aspen wood with a generous seating width of 60 cm. Fully glazed fronts made of 8 mm tempered safety glass—available in clear, Parsol Gray, or Parsol Brown—combine transparency with protection, while chrome-plated or optional black hardware completes the overall look.

Flexible technology for any space—in the Savne Štrus Termo Pure Indoor Sauna heat-treated

The Termo Pure I is the only model that can be operated with a standard 230-V single-phase connection, making it ideal for smaller rooms without a high-voltage electrical installation. All larger models (Termo Pure II–VIII) require a 400-V three-phase connection with fuses ranging from 16 to 25 A, depending on the selected heater output between 4.5 and 10.5 kW. The recommended cable cross-section is 5 × 2.5 mm² up to 9 kW or 5 × 4 mm² at 10.5 kW—installation must be performed exclusively by a licensed electrical contractor. Linear ambient lighting under or behind the bench is included as standard on all models.

Eight models, one goal—your sauna experience with the Termo Pure Indoor Sauna from Savne Štrus

From the compact Termo Pure I, just 140 cm deep, which fits even in cramped bathrooms, to the spacious Termo Pure IV with its L-shaped bench seating, the collection offers the right solution for every living situation. Models with side glass (V), partial glass (VI), or as a corner variant (VII) expand the design possibilities and seamlessly integrate the sauna into open-concept living spaces. The sloped ceiling version (VIII) accommodates architectural features such as sloped roofs or suspended ceilings. Operation is handled via BASE, LUMEN, or TOUCH, depending on the selected control system—ranging from a simple Finnish infrared control to a full-featured touch control with BIO function and WiFi remote access.

Health and regeneration with the Savne Štrus Termo Pure Indoor Sauna heat-treated

Regular sauna use promotes blood circulation, supports muscle recovery, and strengthens the immune system—benefits that can be enjoyed at any time in your own Indoor Sauna, without the need for travel or waiting times. The reduced thermal conductivity of the thermally treated aspen ensures a pleasantly mild surface temperature, guaranteeing a comfortable seating experience even during longer sauna sessions. Optional salt walls, starry sky lighting, and aroma systems enhance the wellness experience and create a holistic atmosphere of relaxation. The Savne Štrus Termo Pure Heat-Treated Indoor Sauna thus becomes an integral part of your personal health routine.
