And yet, these two letters are displayed everywhere: in restaurants, train stations, hotels… A universal acronym that seems obvious, but whose meaning remains unclear to many. So, what do these famous initials hide? You’ll see: it’s more than just a plumbing story.
Where does the expression « WC » come from?

The acronym « WC » is short for « Water Closet , » an English term that literally means « water closet . » Not very poetic, it’s true… But at the time it appeared, this expression simply referred to a small enclosed room containing a toilet with running water , as opposed to the famous outhouses at the bottom of the garden.

A bit of history: toilets before modern comforts

Until the 19th century, in many Western countries, most houses did not have indoor toilets . People relieved themselves outside, in latrines, or in chamber pots which were then emptied… elsewhere. The first “bathrooms” were not necessarily equipped with toilets, but rather with bathtubs or sinks.

It was only towards the end of the 1800s, with the arrival of indoor plumbing systems, that toilets began to be installed in dwellings. They were then placed in a small room separate from the bathroom, called a « water closet » .

Why do we still use « WC » today?

Even though modern bathrooms often include a bathtub, sink, and toilet, the abbreviation « WC » is still widely used , especially in public places. Why? Because it’s a simple abbreviation, understood internationally . It can be recognized in many countries, even without speaking the language.
