The SunRay Cayman is a 4-person outdoor traditional wet/dry sauna built for real weather: premium Canadian hemlock, double-panel wall construction, a fully sealed weather-resistant cabin, and a durable metal roof. Inside, upper and lower benches seat four comfortably while a genuine 6 kW Harvia electric heater with stones brings the cabin to 180°F in 30–45 minutes. Pour water over the stones for authentic wet/dry löyly. Ambient dome lighting, a thermohygrometer, and a sand timer are included, and DIY assembly takes about an hour. Requires a dedicated 220V, 40 Amp circuit.
