Glass Floor and Underwater Rooms
A glass panel in the floor is close to standard in French Polynesia and rare in the Maldives, where the equivalent is going further and putting the bedroom itself under the surface. This list covers both: villas with a viewing panel big enough to lie on, resorts with genuine underwater suites, and the small set of underwater restaurants and spas reached from an overwater walkway. We say how large the glass actually is, whether the water beneath holds fish or empty sand, and whether the lights under the deck stay on after dark. The engineering matters as much as the view, since acrylic at depth is a maintenance job and several of these rooms are older than the photographs suggest.
