CLT Structure · Cross-Laminated Timber
The Small Indoor is built from prefabricated cross-laminated timber elements, using dried, strength-graded boards bonded crosswise and CNC-machined for accurate openings and joints. The result is a compact sauna body with structural stiffness, dimensional stability, and the solid timber presence expected from a premium indoor heat room.
Finish · Natural Spruce Inside and Out
This standard build uses Natural Spruce for both the interior and exterior finish, giving the sauna a bright, calm, and architectural character. The vertical timber grain keeps the compact room visually clean, while the natural surface brings softness and warmth to the glass-fronted form.
Glass Frontage · 8 mm Tempered Glass
The glass facade uses 8 mm tempered glass, with a 650 mm glass door and one black aluminium framed window element. It brings openness to the compact indoor sauna without losing the sense of enclosure, giving the timber room a precise and modern architectural front.
Small Format · 2x2 Element Layout
At 1300 x 1378 x 2060 mm externally, the Small Indoor is the most space-efficient indoor format in the OneEighty range. Inside, its 1230 x 1258 x 2000 mm room gives the body enough volume for a focused private sauna ritual without demanding a large dedicated footprint.
Ventilation & Wiring Provision · Built Into the Frame
Natural ventilation is integrated through a wall inlet and an adjustable outlet covered with a grill. The structure also includes cavities in the wall and floor joints for non-visible electrical wiring, allowing lighting, sensors, heater controls, and power paths to be planned cleanly by the installer.
Bench & Interior Elements · Simple, Durable, Direct
The Small Indoor includes prefabricated bench elements with an upper bench, lower bench, and bench support, all treated according to sauna use. The layout is simple and deliberate: no excess, no visual noise, just a clear timber room designed for heat, stillness, and repeat use.
Each sauna includes its standard bench configuration, selected to suit the model, room size, and heat layout. Alternative bench styles may be available depending on the sauna range, model, and configuration, with final layout, lighting impact, and pricing confirmed before order.
Available options are confirmed during your private consultation. Some layouts may require additional timber, adjusted lighting, or model-specific changes.
Across wellness research and performance culture, sauna bathing continues to be studied for its role in recovery, circulation, and ritual.
You get used to everything. 88 degrees in the sauna used to feel way hotter. Now it almost feels normal. I’m trying to get in here 4 times a week. The benefits are tangible. One of the wildest feelings you can experience is when you do 20 minutes in a hot sauna and then 2 in a cold plunge, and then back to the sauna.
The latest data point to: i) 57 minutes of hot sauna per week ii) 11 minutes of cold exposure per week as reliable thresholds to derive major benefits on metabolism, insulin and growth hormone pathways. (Can be done same or separate days) (Ideal temp: uncomfortable but safe)
I have been hitting up my home sauna 5 days a week and every time I feel great afterward. Regular sauna use has been associated with up to a 40% reduced risk of pneumonia and increases white blood cell numbers and heat shock proteins. Thirty minutes at 73°C boosts hsp70 by 50% in healthy people.
