The design motto of INVENTIO II is slimness and sleekness. Two control handles for water flow / diverter and On-Off / Temperature are the key factors allowing convenient and intuitive use. User’s control of the handles to change flow rate and temperature is displayed into the LED’s colors and brightness. This visual feedback enables the intimate interaction between user and the product effecting ease of use, visual entertainment and safety enhancement. In addition, the wide square shower head adds to the fresh and rich feeling of shower.
