What Does “WC” Really Mean – And Why Do We Call It That?
Have you ever walked past a sign marked “WC” outside a public restroom and found yourself wondering, “What does that even stand for?”
You’re not alone. While it’s a common abbreviation seen around the world—especially in airports, restaurants, and hotels—many people are still puzzled by the mysterious letters. Spoiler alert: it stands for “Water Closet.” But don’t worry, you’re not the only one who finds that term just as confusing as “restroom” or “bathroom.”
A Tale of Many Toilets
In a hilarious 2020 TikTok clip, a couple named Shelby and Dylan poked fun at the weird names we give to public toilets. Dylan walks past a “washroom” sign and quips, “What are they washing in there? Oh, it’s a restroom. The only thing I wash in there is my hands.”
Shelby chimes in, “Do you rest in a restroom?”
Touché.
Their video struck a chord with viewers who flooded the comments with their own toilet terminology preferences. “It’s called a bathroom, restroom, washroom, and toilet,” one person wrote.
Another shared how, while visiting Disneyland, they asked for the “washroom” and were directed to the laundromat. Oops.
One commenter even added, “Wait until he learns about water closets.”
So… What Is a Water Closet?
According to Merriam-Webster, a water closet is “a room or compartment with a toilet.” The term dates back to the 19th century when indoor plumbing was just becoming a thing. At the time, homes might have had a bathroom for actual bathing, but the toilet often lived in a separate, tiny space—a literal “closet” with water.
This is where WC was born.
The abbreviation WC stuck around, especially in Europe and other parts of the world, as a polite and universally understood way to indicate the presence of a toilet.
A Global Game of Names
Depending on where you live, the room we all rush to in an emergency goes by many names:
-
Bathroom
-
Restroom
-
Washroom
-
Loo
-
Toilet
-
Lavatory
-
WC
-
The John
-
Powder Room
And if you ask the internet, things get even funnier. One Reddit user asked, “Why is it called a WC if it isn’t even a closet?” Another pointed out that in Russia, it’s known as “a room without windows,” even if it actually has a window.
Meanwhile, Esperanto speakers call it necesejo—which literally translates to “necessary place.” Hard to argue with that logic.
In Canada, “washroom” is the norm, while parts of the U.S., like the Midwest, also use the term. Elsewhere in America, “bathroom” and “restroom” dominate—even though very few of these rooms contain a bath or are meant for actual resting.
The Evolution of the WC
Before the late 1800s, toilets were often found in outhouses. Only the wealthy had indoor water closets. By the early 20th century, indoor bathrooms with toilets became the norm in many parts of the world.
The term “water closet” eventually evolved to describe a small, enclosed toilet room within a larger bathroom. These modern-day WCs often include a tiny sink, making them self-contained and handy for guests.
Today, “WC” is commonly seen on signage in places that cater to international travelers because it’s one of the more widely understood toilet terms around the globe.
So, What Do You Call It?
Are you team bathroom? Restroom? Washroom? Or do you prefer calling it the necessary place, like the Esperantists?
