Why Is a Bathroom Called a Head? (And Other Strange Bathroom Slang)

Ever wondered why a bathroom is called a head? It sounds strange, right? But the answer goes way back, like, sailing ships and pirates kind of back. Let’s take a quick trip into history and break it down in plain, everyday language.

So Why Is It Called The Head?

Back in the day, when people traveled the world by ship, sailors didn’t exactly have fancy restrooms. Instead, they went to the front of the ship the “head” of the vessel. That’s where a small area was set up for sailors to do their business over the open sea.

There were two smart reasons for this setup:

  1. Wind direction. Ships couldn’t sail directly into the wind, so the front of the ship was usually downwind. That helped carry the smell away from the crew.

  2. Easy clean-up. Waste would go straight into the ocean no plumbing needed.

So that’s why a bathroom is called a head. It comes from where sailors used the toilet at the head of the ship. Over time, “the head” slang for toilet stuck, and even modern sailors still use it.

Other Bathroom Slang Around the World

People use all kinds of bathroom slang, depending on where they live or who they’re talking to. Here are some you might’ve heard before:

1. Loo

Common in the UK. One theory says it comes from the French word “l’eau” (water). Another says it came from “Waterloo,” a popular toilet brand in England.

2. Latrine

Still used by military folks or in camping. It’s just a fancy word for an outdoor toilet or bathroom area.

3. Dunny

If you’re in Australia and someone says “Where’s the dunny?”—they mean the toilet. It’s often an outdoor or bush toilet. The word came from “dunnekin,” meaning dung house.

4. Lavatory

A more formal way to say bathroom. Comes from the Latin word lavare, which means “to wash.” You’ll see this on airplanes and in fancy places.

5. Jacks or Jakes

Old-school terms from England and Ireland. “Jakes” was used in the 1500s, and “Jacks” is still used in parts of Ireland today.

6. Water Closet (WC)

You’ll see signs that say WC in many parts of Europe. It stands for “Water Closet,” a polite way to say flush toilet.

7. Bog

A very British way to say toilet. It originally referred to a swampy area, but now it’s just casual slang. “Bog roll” is slang for toilet paper.

8. John

Common in the U.S. Some say it comes from Sir John Harrington, who invented a flushing toilet in the 1500s. Others think it just sounds like a common name and has become everyday slang.


So, What Have We Learned?

The next time someone asks why a bathroom is called a head, you’ll know it all started with sailors trying to avoid bad smells and make waste disposal easy. And when it comes to the head slang for toilet, it’s one of the oldest bathroom slang terms still in use today.

Whether you call it the head, the loo, the john, or even the bog, it all means the same thing. Just be glad you don’t have to hold onto a wooden rail at the front of a ship whenever you need to go!

Alex did a great job installing my kitchen faucet and an under-sink Aquasana water filter. He also addressed a few other plumbing-related issues. He was friendly and helpful. Excellent work!

Very very happy with the work Alex did for us replacing the tanks in our Aquasana filtration system. From first contact over the phone through job completion Alex was a pleasure to work with. He explained what he was doing, and why, every step of the way, and made sure we understood what we needed to do to maintain the system. Strongly recommend Alex!
