Why Do We See “WC” and Toilet Icons Everywhere?v

Many people today use toilets without ever thinking about where they came from or how this essential invention evolved.

The history of the toilet is far richer and more fascinating than most realize, involving royalty, inventive minds, and centuries of refinement.

So, who actually invented the modern toilet—and when did it happen?

The credit generally goes to Sir John Harrington, an English courtier, writer, and godson of Queen Elizabeth I.

In the late 16th century, he developed what he called a “water closet,” a system that used water to flush waste from a bowl into a drainage area.

Harrington successfully installed one of his early models for Queen Elizabeth I at her palace in Richmond, marking one of the first recorded uses of a flushing toilet in the royal household.

The basic idea behind his invention still defines how toilets work today: water flows through the bowl, pushing waste into the drain and out of the home.

Interestingly, the word “toilet” itself comes from the French word toilette, which originally described a small dressing room where one would wash, comb hair, and apply makeup—quite different from the meaning it carries now.

Over the centuries, various names and terms have been used to describe toilets, each with its own background:

  • WC (Water Closet): Refers to the original term used for early flushing toilets.

  • Loo: A casual British term, likely derived from “lavatory.”

  • Smallest room: A polite or humorous way to refer to the bathroom.

  • Latrine: Used historically, especially in ancient Rome, for public toilet rooms.

  • Privy: A private or more secluded toilet, often found outdoors in older homes.

  • 00 (Double Zero): Used by hotels in Europe to denote the toilet, as that room number wouldn’t be assigned to guests.

While the earliest designs laid the foundation, it wasn’t until centuries later that toilet systems became widely accessible.

A major part of that progress is owed to Villeroy & Boch, a company that began more than 275 years ago and continues to shape the world of sanitation.

With the advent of running water in the 19th century, Villeroy & Boch revolutionized sanitary technology.

The company introduced more hygienic systems, standardised production of sanitary ceramics, and contributed greatly to the separation of fresh and waste water—an essential development for modern plumbing.

They became pioneers in designing toilets with improved drainage systems, setting standards that influenced both residential and public sanitation across Europe and beyond.
