Every day, billions of people sit on a toilet.
But have you ever wondered… who actually invented it? And why does this life-saving invention come wrapped in embarrassment, taboo, and a whole lot of awkward silence?
In this episode, we pull the lid off one of humanity’s most essential — and least discussed — technologies.
From ancient clay seats in Mesopotamia to the high-tech, music-playing smart toilets of modern Japan, the story of the toilet is packed with ingenuity, engineering breakthroughs, and some truly strange ideas. We’ll travel through ancient civilizations, medieval cesspits, Victorian taboos, and global sanitation challenges to uncover how managing human waste shaped health, cities, and even social equality.
Along the way, we’ll meet inventors like John Harington, Alexander Cummings, Joseph Bramah, and the famously misunderstood Thomas Crapper — plus the many overlooked engineers whose quiet innovations changed the world from the bathroom outward.
We’ll explore the big themes:
- Human hygiene — How sanitation determined life expectancy, health, and the survival of entire cities.
- Innovation — Why S-traps, valves, and flush mechanisms mattered as much as any great invention.
- Taboo — Why something everyone does every day became one of society’s most avoided topics.
- Cultural attitudes — From Roman sponge etiquette to Victorian euphemisms to global sanitation disparities today.
- Modern technology — Smart toilets, gender-inclusive restrooms, and the continuing fight for clean, safe facilities worldwide.
And of course… we’ll sprinkle in weird patents, toilet museums, celebrity bathrooms, space toilets, gold toilets, and hilariously bizarre inventions people actually tried to patent.
By the end of this episode, you’ll never look at a toilet the same way again.
Instead of a mundane bathroom fixture, you’ll see it for what it truly is: a brilliant piece of engineering, a window into cultural values, a lifesaving public health tool… and yes, a topic that still makes us blush.
