A Brief History of the Throne

Humanity has always needed a way to separate people from their waste, but the journey from holes in the ground to the porcelain throne was long and winding.

Royal Beginnings

While many credit Thomas Crapper, the true godfather of the flush is Sir John Harrington. In 1596, he installed the first flushing device for his godmother, Queen Elizabeth I. She called it her “Ajax.”

Despite the royal approval, the invention didn’t catch on right away. Most people were content with chamber pots and cesspits for another couple of centuries.

The S-Trap Breakthrough

The real turning point came in 1775. A Scottish watchmaker named Alexander Cummings patented the S-trap, now known as the U-bend. This simple curve in the pipe holds a little water to form a seal, blocking foul sewer gases from rising back into the home.

Without Cummings, indoor toilets would smell unbearable.

Crapper’s Marketing Genius

So why do we associate the toilet with Thomas Crapper? He was a skilled plumber and businessman in the late 19th century who heavily promoted sanitary plumbing. He owned one of the world’s first bath showrooms and branded his products with his name. American soldiers in World War I saw the name “Crapper” on the cisterns and brought the slang term home.

The Roman Sponge Stick

Sanitation in Ancient Rome was social but, by modern standards, fairly grim. Public latrines were common, but toilet paper was centuries away. Instead, Romans used a tersorium.

This device was a sea sponge attached to a stick. After doing your business, you would wipe, rinse the sponge in a bucket of vinegar or brine, and leave it for the next person.

The Global Sanitation Crisis

While we argue about leaving the seat up or down, billions of people are fighting for basic dignity. The World Health Organization and UNICEF track these numbers closely, and the reality is stark.

Access to Safe Toilets

Access to a safe toilet is a human right, yet about 3.5 billion people live without safely managed sanitation. That means their waste isn’t reliably contained or treated, which creates serious health risks.

On top of that, 419 million people still practice open defecation, going in fields, forests, or bodies of water. This is a primary driver of disease transmission in developing nations.

Health Impacts

The lack of sanitation has devastating consequences. Around 1,000 children under five die every day from diarrheal disease linked to unsafe water, poor sanitation, and inadequate hygiene.

When communities don’t have toilets, waste contaminates the groundwater. This creates a vicious cycle where the water people drink makes them sick.

Economic Drain

Poor sanitation also drags down the economy. The World Health Organization estimates that every $1 invested in sanitation returns about $5.50 to society through lower health costs, higher productivity, and fewer premature deaths.

When children, especially girls, have access to private toilets at school, attendance rates climb. Without them, many girls drop out once they reach puberty.

Scary Toilet Truths

You might want to close the lid before reading this section. Bathrooms are convenient, but they are also one of the germiest rooms in the house.

The Toilet Plume

This is the single best reason to close the lid before you flush. When a toilet flushes, the turbulence creates an aerosol mist known as a “toilet plume.”

This invisible cloud can carry fecal bacteria, E. coli, and norovirus into the air. In 2022, University of Colorado Boulder researchers used bright green lasers to photograph the plume and clocked particles shooting out of the bowl at up to 6.6 feet per second, with the smallest aerosols hanging in the air for minutes afterward ⁽¹⁾. If your toothbrush sits on the vanity nearby, it is likely catching some of that spray.

The Hand-Washing Gap

We all like to think we are hygienic, but the stats say otherwise. Studies suggest that most people don’t wash their hands long enough to remove germs effectively.

Even worse, around 20 percent of people don’t wash their hands at all after using the toilet.

The Dirty Truth About Phones

We are all guilty of it: scrolling through social media on the throne. The trouble is that phones heat up in your hand, creating a warm home for bacteria.

Because we constantly touch our phones and rarely disinfect them, they often carry more bacteria than a freshly cleaned toilet seat.

Fun and Bizarre Facts

Now that we have covered the heavy stuff, here is the lighter side of the loo.

The Most Expensive Toilet

The International Space Station has the most expensive toilet in history. NASA spent roughly $23 million on a system that uses suction and airflow to handle waste in zero gravity. It even recycles urine back into drinking water.

The Musical Flush

If you have perfect pitch, you might notice something familiar about your bathroom breaks. Most American toilets flush in the musical key of E-flat.

World Toilet Day

Yes, there is a day for everything. November 19 is World Toilet Day. It was established by the World Toilet Organization in 2001 and later adopted by the UN to raise awareness about the global sanitation crisis.

Japan’s High-Tech Thrones

If you want to see the future of toilets, go to Japan. The “Washlet” style toilets are standard there. Features often include heated seats, bidet functions with adjustable water pressure, warm air dryers, and even noise-masking sounds to cover up embarrassing splashes.

Slang for the Commode

English is a colorful language, and we have developed countless names for the bathroom. Here are some of the most common terms from across the globe.

• The Loo (UK).
• The John (USA).
• The Dunny (Australia).
• The Crapper (USA).

Who Knew Toilets Were So Interesting?

For all the jokes, the flushing toilet ranks among the most important inventions in history. Reliable sanitation has prevented more disease and saved more lives than almost any other technology.
