Who invented the flush toilet? History & Brief Overview

Did you know that the toilet has thousands of years of history attached to it? Surely with so much history, we all must have wondered at some point of the other, who invented the flush toilet? Read below to find out!

Let us read about Who invented the flush toilet? History & Brief Overview

1) The earliest known toilets

The earliest known toilets were excavated in Mesopotamia. Dating back to c.3200 BCE, they were known as internal pit toilets. However, history’s first known modern sanitation systems with toilets having a water flowing facility were found in Mohenjodaro, a site in the Indus Valley Civilisation.

2) The Roman civilisation used communal latrines, these toilets did not have a flush in the modern sense but had a continuous stream of running water to wash away the waste.

3) In 1206, Al-Jazari, a Persian inventor, constructed a handwashing device which became the basis of the flush mechanism. This automation is now used in contemporary flush lavatories.

4) The contemporary flush latrine was invented by the ‘saucy’ Godson of the queen

The credit for one of the first contemporary flush toilets goes to Sir John Harington, an English courtier and the Godson of Queen Elizabeth I. When he was at the royal court, he devised the first flushing toilet of England, called ‘Ajax’. Subsequently, he described his new creation in his popular book.

5) Harington’s invention

Harington’s flushing toilet was essentially an oval bowl. It was 2-foot-deep and was covered with resin, wax and pitch. And it provided water from an upstairs cistern. Flushing it required 7.5 gallons of water. Additionally, he noted that when water was in short supply up to 20 people could use his innovation between flushes. Subsequently, he installed the working model of the device at Richmond Palace.

6) Even though Harington came up with the model of the first contemporary flushing toilet, it would take many centuries and industrial boom for it to catch on.

7) Alexander Cummings patented the first flush toilet design in 1775

One of the biggest problems with Harington’s creation was that it made use of a straight pipe. As a result, a foul smell would emit from the pipes. Cummings was a Scottish watchmaker and mechanic who improved the flush mechanism of the toilet and gave it an S-shaped pipe. This way the pipes retained the water within the water pipe and thus the problem of the foul smell was essentially solved.

8) Subsequently, Samuel Prosser invented and patented a device called the “plunger closet”. Post which Joseph Bramah, an inventor, refined his idea. He did so by using a hinged flap instead of the usual slide valve. Thus sealing the bottom of the bowl.

9) George Jennings’ public toilets

Geroge Jennings was a plumber and an English sanitary engineer who came up with the innovation of a washout closet(toilet). This design had a shallow basin with a dished tray and water seal. The flush water drove the waste into the pan and then through the S-bend pipe. Additionally, these water closets were installed at the Retiring Rooms of The Crystal Palace in 1851 and thus were the first public toilets.

10) Thomas Crapper- manufacturer of one of the first widely successful lines of flush toilets

Contrary to popular belief, Thomas Crapper was not the inventor of the toilet. However, he did develop the floating ballcock which is used for regulating the filling of the tank; a mechanism still used in contemporary latrines today. Additionally, he even improvised the S-bend pipe by making it into a U-bend pipe.

11) You have American soldiers to thank for popularising the word “the crapper”

The name “Crapper” almost became associated with toilets thanks to the American soldiers stationed in England during World War II. At the time the company “Thomas Crapper & Co Ltd”, were one of the biggest mass producers of flush toilets. Consequently, their logo appeared on them as well. Due to this, the soldiers then started referring to them as “the crappers”. The name stuck and subsequently, they bought this term back to the U.S.

In conclusion, there is no single man who ‘invented’ the flush toilet, rather there were several who made improvements over a design over several decades.
