A large, deep rock container maximizes contact between the rocks and the heating elements for safe, efficient heating. Triple-wall construction provides added insulation and safety. Optimum airflow, heat retention and humidity control are derived from surface contact in the chamber between the stainless steel heating elements and igneous stones. This combination of design features result in quick, humidity-rich, unwavering heating performance while maintaining safety with a cool exterior.
