What is "sanisette"

Sanisette is a registered trademark for a self-contained, self-cleaning, unisex, public toilet pioneered by the French company JCDecaux. These toilets (and other similar toilets) are a common sight in several major cities of the world, but they are perhaps most closely associated with the city of Paris, where they are ubiquitous. In the United Kingdom they (along with automated public conveniences of other brands) are known informally as "Superloos".
