Choosing the right wood is crucial for comfort, aesthetics, and longevity. At inup, you'll find exclusive wood types that meet the highest standards – for saunas that are far more than just functional.
Why wood is the heart of every sauna
Wood possesses properties that are indispensable in a sauna:
-
Heat-conducting without overheating
-
Regulates humidity, creating a stable microclimate.
-
Antiseptic & hygienic
-
And last but not least: a natural, calming aesthetic.
Wood "lives" with you; it breathes, regulates, and dampens. It transforms every room into a sensory experience.

Premium wood types from inup – your sauna, stylishly presented
Whitewood aspen
A light, almost silky wood with a gentle grain – ideal for minimalist sauna designs. Aspen appears open, clear, and airy. Its low thermal conductivity means it remains pleasant against the skin even at high temperatures. The perfect choice for those who appreciate Scandinavian tranquility and purity.

Black alder ( thermally treated )
A deep, elegant brown with shimmering nuances – the thermal treatment creates an almost coffee-colored depth, ideal for contrasts or luxurious, all-over interiors. robust, low warpage and highly dimensionally stable.
Black alder (thermally treated & brushed)
Same base tone as the standard thermo-treated version – but with a noticeably more textured, tactile surface. The brushing accentuates the wood grain and gives the material a natural feel. Ideal for design enthusiasts who value material authenticity.
New Zealand pine (thermally treated)
A vibrant, expressive shade of brown with a flowing grain. The texture is dynamic and full of character, almost like a landscape painting. The perfect choice for designer saunas with individuality and depth. Despite its visual warmth, it remains dimensionally stable and moisture-resistant.
