Natural, the new Effe collection designed by Marco Williams Fagioli, presents 3 coordinated models for the 3 heat therapy functions: hammam, Finnish sauna, and infrared cabin. The enclosure of the 3 models is coordinated, with large glazed panels and an external structure made from high-quality wood: Natural is particularly suited to integrating with the home living zone or elegant private spas. In the Natural series, the lateral frosted glazed panel is designed to enhance the brightness of the environment: the effect of the chromotherapy present in the Hammam is particularly charming and relaxing.
