## The Foundation of Your Sauna: Wood Selection
When it comes to sauna construction, wood is king. It’s not just about aesthetics; wood’s natural properties make it an ideal material for creating a truly authentic sauna experience.
### Why Wood Reigns Supreme
* **Heat Retention:** Wood is an excellent insulator, trapping heat efficiently and creating a warm, cozy environment.
