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

Many people are unaware of the exact history behind the modern toilet or how it came to be part of everyday life.

Who invented the modern toilet, and when?

The invention of the early form of the modern toilet is credited to Sir John Harrington, an English courtier and godson of Queen Elizabeth I. In the late 16th century, around 1596, Harrington developed a flushing device he called a “water closet.” He even installed one of his prototypes for the Queen at her residence in Richmond Palace. Although his invention was not widely adopted at the time due to high cost and limited plumbing technology, it laid the foundation for the toilets we use today.

A toilet, or water closet, is essentially a system that uses water pressure to flush human waste from a bowl into a drainage system. When water flows through the toilet, it pushes the waste down the pipe, preventing odors and maintaining hygiene. Interestingly, the English word "toilet" comes from the French word “toilette,” which originally referred to a small cloth used during grooming, and later to the room in which grooming or dressing took place.

Common Toilet-Related Terms and What They Mean

  • WC: Abbreviation for water closet, commonly seen on restroom signs in Europe.

  • Loo: A casual British term meaning lavatory or bathroom.

  • Smallest room: A polite euphemism referring to the toilet room due to its typically small size.

  • Latrine: A public or communal toilet, historically used in ancient Roman baths and military camps.

  • Privy: A private outdoor toilet, commonly found before indoor plumbing.

  • 00 (Double Zero): A term used in some old hotels to designate a restroom, as room number “00” was never assigned to guests.

The Rise of Modern Bathroom Innovation

The foundations of the renowned ceramics and sanitary manufacturing company Villeroy & Boch were established over 275 years ago. With the arrival of modern plumbing and the widespread introduction of running water in the 19th century, bathrooms began to evolve dramatically. During this era, Villeroy & Boch played a leading role in transforming sanitation standards across Europe.

Early milestones included:

  • Standardizing hygiene practices in domestic and public restrooms.

  • Introducing mass production of high-quality sanitary fixtures.

  • Developing systems that separated fresh water from wastewater to improve public health.

  • Innovating toilet bowl and drainage designs to ensure cleaner and more efficient flushing.

If you’ve ever wondered how a toilet drainage system works or how modern flushing mechanisms are engineered, Villeroy & Boch has been instrumental in shaping these advancements.

From Practical Utility to a Space of Well-Being

In 1975, designer Luigi Colani reimagined the concept of bathroom interiors in collaboration with Villeroy & Boch. Instead of viewing the bathroom solely as a functional, utilitarian space, Colani emphasized comfort, aesthetics, and atmosphere. His designs incorporated smooth, organic shapes and a sense of relaxation, helping shift cultural perceptions of the bathroom.

This marked a turning point: the bathroom was no longer just a place for washing. It became a personal sanctuary—a space for tranquility, self-care, and wellness. Thanks to innovations like these, the bathroom today is considered just as important for living comfort as the living room or bedroom.
