This is a 4-person indoor sauna cabin. The ThermaSol Aalto (Model 14-AALTODL/R, SKU SAK13285) is a made-to-order sauna cabin designed for permanent indoor installation in residential or commercial spaces. It is built for households or facilities that want a traditional Finnish-style sauna with a modern, open aesthetic — the semi-panoramic transparent glass corner and brushed Tyrol wood exterior panels distinguish it from fully enclosed cabin designs. The included Harvia Virta 9kW Wi-Fi heater and Harvia Xenio CX45 digital control are factory-fitted.
