âWCâ on bathroom signs stands for âWater Closet,â an old term for a toilet room. Common in airports and hotels, it confuses many.
A 2020 TikTok by Shelby and Dylan joked about terms like âwashroomâ and ârestroom,â asking if anyone really rests or washes in them.
The video went viral as people shared their preferred termsâbathroom, washroom, toilet, or WC. Historically, âWater Closetâ referred to a room just for the toilet when bathing was done separately.
As indoor plumbing spread in the 19th and 20th centuries, WC became a global label, especially for travelers.
Reddit users have debated the term, with some puzzled by the âclosetâ part and others sharing international variations, like Russiaâs âroom without windows.â In Canada, âwashroomâ is popular; in the U.S., itâs usually âbathroomâ or ârestroom,â depending on the region. Whatever term you use, they all describe the same place.
Have you ever noticed the letters WC posted outside a public bathroom and wondered what it means?
If so, youâre not alone as people around the world are trying to unravel the mystery of the WC, a space that identifies a room containing a toilet and a sink.
And while weâll offer you an explanation of the WC, we canât promise the term will make anymore sense than restroom, bathroom or looâŚ
In 2020, a couple named Shelby and Dylan shared a TikTok video that revealed a major difference in how some Americans and Canadians do their business.
âWhat in the world is a washroom?â asks Dylan as he walks by sign that says âwashroom.â
âAnd what are they washing in there? Oh, itâs a restroom. The only thing I wash in there is my hands,â he tells his wife. Off-camera, Shelby can be heard asking: âDo you rest in a restroom?â
âThatâs a good point. They both donât make much sense,â Dylan adds.
Online users jumped into the comments section, offering their opinions on the term they prefer to use for the sacred room. âItâs called a bathroom, restroom, washroom and toilet,â offers one user.
A second follower said when they were visiting Disneyland, they âasked for the washroomâ and they âsent me to the laundromat!â
A third adds, âWait âtil he finds out about water closets.â
Water closet
According to Mirriam Websterâs Dictionary, âwater closetâ is a noun that describes âa compartment or room with a toiletâ or âa toilet bowl and its accessories.â
Back in the day, when someone would use the bathroom, it was to take a bath. And when a person used a restroom, it was apparently to rest or get ready for the day by using the sink and mirror.
Lastly, if you needed to go potty, you would use the toilet in the water closet. Depending on where you live in the world, the room that holds the porcelain throne goes by various names including the loo, restroom, bathroom, washroom, lavatory or WC.
In modern days, youâll often see signage indicating WC in public spaces like airports, restaurants, or hotels. Itâs just another way of saying ârestroomâ or âbathroomâ but is often associated with a more formal or universal sign in places catering to international travelers.
History of the WC
Before the 19th century in America, indoor toilets were a luxury, reserved primarily for the wealthy. Most people used outhouses or other outdoor facilities for their sanitary needs. While homes often had âbathroomsâ for bathing, these rooms typically didnât include toilets. The widespread installation of indoor plumbing began in the late 19th century, with the advent of the water closet by 1890. These rooms housed the toilet separately from bathing spaces.
It wasnât until the early 20th century that the modern bathroom, combining both bathing facilities and toilets into one integrated space, became common.
While combining toilets and bathtubs in the same room was a practical solution for saving space and simplifying plumbing, this arrangement did reduce privacy, especially in shared spaces.
Since, the term âwater closetâ evolved to refer to a small, enclosed room within a larger bathroom, dedicated solely to the toilet. These water closets often include a small sink for handwashing, making them self-contained and convenient.
Attempting to demystify the water closet, online users shared their opinions on Reddit in a post called, âWhy is a public WC called bathroom if there is [no] bath?â
Responding to the message, a Redditor writes, âAmericans might similarly ask: âWhy is it called a WC (water closet) if it isnât even a closet?â the comment continues to explain that a âbathroomâ or ârestroomâ is the âpreferred US euphemism for âroom with toilet,â whereas other places use âWC,â âlavatory,â âlooâ etc.â
âIn Russian itâs âa room without windowsâ even if there actually is a window,â shares a third while another adds, âIn Esperanto, itâs necesejo, or ânecessary placeââ
Meanwhile, other Redditors discussed washroom versus bathroom and restroom.
âCanada famously uses Washroom,â says one netizen while another clarifies, âIâm from the midwest, and washroom is fairly common here. Bathroom or restroom are probably used the most though.â
âBest one, I think. You should be washing in there,â adds another. ââŚnot resting.â
