Charleston 4-Person Indoor Traditional Sauna

he Sunray Charleston 4-Person Indoor Traditional Sauna delivers a full, communal sauna experience from the comfort of home. At its heart is a 6.0 kW Harvia electric heater, capable of reaching up to 170°F, and a water cask and ladle let you steam the stones to dial in your preferred humidity. The sauna’s two-tier, double bench seating accommodates four people with ease—or gives two the space to lie back and relax. 

Built from natural Canadian Hemlock, the Charleston combines strength with warm aesthetic appeal. It also includes practical touches like a thermo-hygrometer for tracking temperature and humidity, interior dome lighting, a ventilation system, and an ergonomic backrest for enhanced comfort. With exterior dimensions of 71″ W × 63″ D × 80″ H and weighing about 510 lb, it’s a robust, feature-rich model that brings traditional sauna rituals into your daily life. 

The Charleston is designed to be dependable, elegant, and restorative—making it a perfect fit for those seeking a shared sauna experience that supports both relaxation and long-term health.
