Switchable LC Privacy Glass was used in Zaha Hadid's 520w28 HighLine High Rise model Apartment as the bathroom walls surrounding the toilet and rainfall shower. When those amenities are not being used, the glass walls are transparent. When in use, the glass can be switched to "private" and the walls become instantly frosted. According to Leanna Garfield of Tech Insider, when I recently toured the model apartments, I felt most mesmerized by the BATHROOM. The marble bathroom seems fairly normal at first. Next to the tub, there are two glass-encased rooms, one for the toilet and one for the rainfall shower. But when you flip the switch on the wall, the smart glass walls instantly frost over. Leanna continued, During my tour, the guide mentioned she always points out the glass to potential buyers because it undoubtedly WOWs them & it makes sense. Its an amenity that more luxury developers are adding to their high-rises, especially in major cities like New York
