Just behind the vanities is a giant window that transforms from opaque to transparent at the flip of a switch, revealing ocean views.
Because bathrooms need to ensure privacy, Hall replaced the room’s tiny window with a much larger one made of Smart Glass. The new 8-by-10-foot window, composed of liquid crystal sandwiched between two panes of glass, transforms from clear to opaque at the flip of a switch. Fabricated by Pittsfield-based LTI Group, the roughly 700-pound window is an inch-and-a-quarter thick and had to be hoisted up to the second-story bathroom by crane. “It was pretty impressive to watch,” says Hall, noting that the expanse of glass was the largest LTI had ever made.

This is beautiful! Outstanding craftsmanship, very impressive. r and e
While the vanities are very beautiful, the article is about the window. Pictures of it when clear and when opaque would more fitting to the article. Instead, there's one photo that barely show the window.
