Website tip: The Bathroom Diaries
The Bathroom Diaries is the world's largest database of restroom locations. It rates over 12,000 public bathrooms in more than 120 countries. They also have a yearly The World's Best Bathroom competition, where you can submit your own favorite public restroom.
Handy for finding public restroom locations when you are on the road. As you know, it's not always that easy, which was proven by a new London initiative actually getting some TV broadcast time at the launch of the Sat Lav scheme by London's Westminster Council.
