Who invented the toilet (to sit on)?

The first practical toilet was invented by the British aristocrat John Harrington.

A brief history of development:

In 1596, the British aristocrat John Harrington invented the first practical toilet - a wooden seat with a water tank and flush valve.

In 1778, British inventor Joseph Brame improved the design of the toilet, using a three-ball valve to control the flow of water in the tank, and a U-shaped elbow.

In the 19th century, the British government enacted laws requiring that every house must install a proper sewage treatment system, and toilets began to improve significantly.

In 1861, Thomas Klepper, a British plumber, invented an advanced water-saving flushing system, and waste discharge began to enter the modern era.

In 1885, Thomas Turvey obtained the first patent for an all-ceramic toilet in the UK. Since then, dozens of improved patents have been issued every year.

In 1914, the Qixin Ceramics Factory (the predecessor of Tangshan Ceramics Factory) opened by the British in Tangshan produced China's first ceramic toilet.

In the 1860s, flush toilets became popular in Europe and the United States, and later spread to Japan, South Korea and other Asian countries.

In the early 1980s, it was only seen in high-end hotels in Beijing, but now it is even used in Beijing’s toilets.
