Sauna lighting
Lighting inside a sauna has to be designed for heat, humidity and placement — not simply selected as ordinary architectural lighting.
We use specialist Finnish sauna-lighting systems, including Cariitti, with solutions designed specifically for hot-room conditions. Depending on the design, this can include concealed indirect LED lighting, fibre optics, heater and stone lighting, bench lighting and integrated architectural details.
Some Cariitti sauna LED systems are rated for ambient temperatures up to 125°C, with IP67 protection and high color rendering, while their glass-fibre systems can tolerate temperatures up to 180°C. For hotter zones, fibre optics allow the light source itself to remain away from the most extreme temperatures.
We generally favor warm, low-glare illumination rather than brightly lighting the sauna. Cariitti recommends 2700K for sauna applications, which suits the restrained, warm atmosphere we design for.
The goal is not to see the light fixture. It is to see the timber, stone, steam and space properly.
