ThermaSol Astra 4-Person Indoor Semi Panoramic Glass Sauna Cabin [Made-To-Order] [14-ASTRADL\R] (SAK90471)

Description

The Sauna That Belongs in the Corner of Your Most Beautiful Room

You close the door and the warmth wraps around you. The glass panels keep your room in view, softened now, framed. You reach out and touch the wall. The brushed Tyrol wood meets your hand with a texture that is warm, raised, and unmistakably intentional.

The ThermaSol Astra is a 3-to-4-person indoor corner-entry sauna cabin with sweeping transparent glass panels, a 9KW Harvia Virta Wi-Fi heater, and brushed Tyrol wood interior walls that elevate the room simply by being in it.

Why Brushed Tyrol Wood Changes Everything

Wire brushing strips away the soft outer layers of the wood face, leaving a raised-grain relief that is visually striking and entirely practical in a high-heat environment. The remaining surface is harder, more dense, and highly resistant to micro-cracking and surface splintering through years of cycling above 175°F. The process also clears surface sap pockets before they become a problem. What you feel against bare skin is smooth, organic, and completely safe.

A Corner Transformed Into Architecture

The corner-entry layout tucks into a primary suite, home gym, or private wellness room with a minimal footprint and maximum visual presence. Two sweeping thermal safety glass panels keep the interior bright and airy.

From outside, the Astra reads as contemporary architecture, a glass-and-wood corner piece that enhances the room it lives in simply by being there. Available in left-door and right-door configurations.

Authentic Finnish Heat, Smartly Controlled

The Harvia Virta 9KW Wi-Fi heater fills the cabin with deep, enveloping traditional Finnish heat. The Xenio CX45 smart control manages temperature, time, and RGB LED lighting from the wall panel or via the MyHarvia app.

Preheat from your bedroom. Step in when it is ready. Pour water over the Harvia stones for löyly-style steam and the full Finnish ritual inside your own home.

Modular, Relocatable, Built to Last

Arrives flat-packed with pre-constructed modular wall panels. Two adults can assemble it without a contractor. Requires a 2-inch air gap from home walls, a level water-resistant floor, and a dedicated 240V (40A) circuit plus 120V secondary line installed by a licensed electrician.
