The Princeton traditional steam sauna is our classic barrel design, which has been a signature product for nearly 40 years. This simple design is highly effective, providing maximum usable space while minimizing excess cubic feet, which means the sauna will heat quickly and efficiently. The Princeton is constructed with rustic cedar, rustic fir, and clear cedar which are soft lumbers that act as excellent insulators. The spacious interior is large enough to comfortably sit 6 individuals.
