We had read about these toilets on the floor before our first trip to Italy about a dozen years ago but have not encountered them so far in Umbria or anywhere in Sicily. In fact, the first time we saw one was in Milano, surprising for such a fashion conscious, modern city. This one was in Verona. So far we have seen several, all in public places like restaurants and the like. Seems very antiquated to us but they apparently still use them up here and it's always an adventure!
