A window in the spa – HT25 Mini The relaxing feeling of having a window in the spa or shower was a frequent request from Coelux customers, but the environmental conditions in these settings were really complicated. Water resistance and temperature changes were difficult to handle. HT25 Mini is the result of a design and engineering process using the optical concept already developed for HT25, but increasing the water resistance to IP65 grade. HT25 Mini won the casambi produc design award in 2022. Client: COELUX Website: coelux.com Date: June 7, 2023 Services: Project management, Concept, Design. Team: COELUX Team
