Queen Elizabeth I complained that the toilet in Richmond Palace smelled bad. 1595, her courtier John? Sir Harrington heard of a fascinating invention when he was traveling in Italy, that is, flushing the dirty toilet with water. So Harrington came to solve this problem and tried to build a toilet in Richmond Palace, which proved to be very successful.

Harrington's design is just a special case beyond the times. This was unrealistic to most people at that time. Most people's lives are still the same.

British inventor Joseph? Brame improved the toilet design in the late18th century. And obtained the patent right at 1778.

It was not until the late19th century that most people used toilets after the sewage system of tap water pipes was installed in European cities and towns.

At this time, many Europeans first enjoyed the benefits of toilets, which was more than 300 years after Harrington's invention.
