How do these transparent toilets work?
These toilets use ‘Smart Glass’ technology, not regular glass. When the toilet is empty, the glass is totally transparent. This lets you easily check from the outside if it’s clean or if someone is inside. But the moment you go in and lock the door, the smart glass instantly turns opaque using an electric current. This means nobody outside can see a thing, giving you complete privacy.
