Wood is far more than just a building material – it is soul, warmth, and atmosphere all rolled into one. It unfolds its full potential, especially in the sauna: natural, soothing, and durable. Choosing the right wood is crucial for comfort, aesthetics, and durability. 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 has properties that are indispensable in the 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 an experience for the senses.
The most important selection criteria for sauna wood
Not all wood is suitable for saunas. The following are crucial:
-
Shape stability in heat and humidity
-
Low resin leakage and risk of splintering
-
Pleasant feel and surface temperature
-
Optics – from calm to expressive
Fine wood types from inup – your sauna, stylishly staged
Whitewood Aspen
A light, almost silky wood with a soft grain – ideal for minimalist sauna concepts. Aspen has an open, clear, and light feel. Its low thermal conductivity makes it pleasant on the skin even at high temperatures. The ideal choice for those who appreciate Scandinavian tranquility and purity.
Natural alder
A warm, soft color with a subtle, fine grain. Natural alder is a versatile choice for both classic and modern saunas—stylish but not overpowering. It brings warmth and comfort to the room without being intrusive.
Black alder ( thermotreated )
A deep, elegant brown with shimmering nuances – the thermal treatment creates an almost coffee-colored depth, ideal for contrasts or full-surface, luxurious interiors. It is robust, low-warpage and highly dimensionally stable.
Black alder (thermo-treated & brushed)
The same basic tone as the standard Thermo version – but with a tangible, tactile surface. The brushing emphasizes the wood structure and gives the material a natural texture. Ideal for design enthusiasts who value material authenticity.
New Zealand pine (thermotreated)
A vibrant, expressive shade of brown with a flowing grain. The structure 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.
