Light-Filled Corner Design

 

 

Crisp brushed Tyrol wood panels wrap the walls, accentuating natural grain patterns and bringing warmth to the interior. Transparent glass panels along the front enhance visual openness, allowing the sauna to feel integrated within the room rather than enclosed.

 

 

The layout is designed to sit comfortably in a corner configuration, making efficient use of space while maintaining a clean architectural presence.

 

 

 

Natural Comfort & Heat Performance

 

 

Inside, smooth thermo-aspen benches provide ergonomic comfort and subtle contrast against the Tyrol wall panels. The combination of textures creates a balanced, contemporary aesthetic grounded in natural materials.

 

 

Multi-layer wood fiber insulation surrounds the cabin, supporting even heat distribution and efficient steam retention during each session.

 

 

At the heart of the experience is the Harvia Virta electric heater, delivering consistent warmth and abundant steam for a restorative sauna ritual.

 

 

 

Customizable Ambiance

 

 

Recessed RGB color therapy LED lighting is thoughtfully integrated throughout the interior. Using the included control system, users can tailor the lighting to suit their mood—whether seeking a calming glow or a more energizing atmosphere.

 

 

 

The ThermaSol Astra Sauna Cabin brings together clean lines, natural textures, and dependable heat performance—creating a serene indoor wellness sanctuary designed for modern living.
