The International Federation of Red Cross and Red Crescent Societies is celebrating World Toilet Day (which by the way, is on November 19th, in case it wasn't already on your calendar) by hosting an interesting competition.

Vote on what you think are the three best toilets in the photos from the collection here.

The winner will be revealed on World Toilet Day.

The IFRC set up Water and Sanitation Emergency Response Units (ERUs) as part of its disaster response system. Since 1996, 57 water and sanitations ERUs have been deployed around the world. Without proper water sanitation practices including hand washing and toilets, deadly diseases such as cholera can be spread. The Water and Sanitation ERU helps get clean water to people in disaster zones to prevent the spread of disease and illness.
