SunRay Charleston 4 Person, Indoor Traditional Steam Sauna | HL400TN

Charleston 4-Person Indoor Traditional Sauna

The Charleston 4-Person Indoor Traditional Sauna is thoughtfully designed to deliver a comfortable, authentic, and deeply relaxing sauna experience in the comfort of your home. Ideal for residential indoor use, this premium sauna combines durable craftsmanship with proven heating performance for consistent, rejuvenating results.

Constructed from high-quality Canadian Hemlock wood, the Charleston offers excellent heat retention, long-lasting durability, and a warm, natural appearance that complements any indoor space. A powerful 6.0 kW Harvia electric heater heats the sauna up to 180°F, providing traditional steam heat for effective relaxation and wellness benefits.

The spacious interior features two-tier bench seating, comfortably accommodating up to four seated users or allowing two users to recline. An ergonomic backrest enhances comfort during longer sessions, while the integrated ventilation system ensures proper airflow and a pleasant sauna environment.

Traditional sauna accessories, including a wooden cask and spoon, allow water to be poured over the heater stones to increase humidity and intensify heat. A built-in hygrometer and sand timer help monitor humidity levels and session duration, while the upgraded door handle provides smooth operation and a secure close.

Backed by a 7-year manufacturer warranty, the Charleston sauna reflects SunRay’s commitment to quality, reliability, and long-term performance.
