Washing your bum after using the loo is normally reserved for young children and fans of the bidet. But the Geberit AquaClean, a toilet with a built in shower spurt, actually cleans your bum as you flush, then blows soft, warm air to dry your tender bits clean.
The British are generally a nation of toilet paper softies, but the bidet is widely used throughout Europe. However, elsewhere in the world – Arabic world, African continent and Asia – washing your bum is the preferred method of cleaning. The tools and techniques may vary – bucket rinse, shower douche, bidet – but there is no paper involved.
