For just £60 you can twin your toilet at home, work or school with a latrine in Burundi. Your smallest room will be twinned exclusively with your own individual latrine in the remote Giharo Commune of Rutana Province. Only your toilet will be twinned with that particular latrine.You can even locate your twin deep in the African bush via Google Earth!
A suggestion: From We Are What We Do. Put a money pot on top of your toilet, and spend a penny every time you spend a penny!
