Toilets did not flush
About 2500 Bc: The Harappan city dwellers of the Indus Valley (present-day India and Pakistan) build the earliest known indoor toilets. The toilets, which do not flush, empty into a brick-lined sewer system. This plumbing technology is lost to the region when the cities are invaded around 1500 BC. For thousands of years to come, most advances in toilet technology will take place in Europe.

Crete plumbers make first flushing toilet for the queen
About 1500 bc: Plumbers on the Greek island of Crete install the world's first flush toilet in the queen's bathroom. When the queen flushes, a tankful of rainwater is released into the bowl and washes her doings down clay pipes that run through the palace. Unfortunately, an earthquake destroys the royal house around 1400 Ac. It will be many centuries before toilet technology rises to this level again.

In Rome, public toilets built above the sewer
11,00 seats and no privacy

As many as 11,000 seats are lined up in rectangular rooms along stone henches--with no partitions for privacy. For wiping, there's a sponge on the end of a stick. Just one, though: Roman latrine-users have to share.

1300 AD: By now many Europeans are doing their business in outhouses, tiny sheds with a seat built over a deep hole in the ground. About this time, an English outhouse-cleaner known as Richard the Raker meets an unpleasant end: While cleaning out the smelly waste that has built up in the pit under his own outhouse, Richard falls through the rotted wood floor and drowns "monstrously in his own excrement."
