When you’re planning a bathroom renovation or upgrade the term “water closet” comes up and many of us are left scratching our heads. What is a water closet and why does it matter? Don’t worry this guide will take you from confused to clear, breaking down its purpose, benefits, size and style. Whether you’re a first timer or a seasoned DIYer understanding water closets is key to a functional and beautiful bathroom.
What Is a Water Closet? The Facts
At its simplest a water closet is a small enclosed space in the bathroom where the toilet sits. The term comes from the 19th century when indoor plumbing was a luxury and having a separate room for the toilet was a big deal.
Today water closets are private spaces within modern bathrooms, providing privacy and functionality. Open concept bathrooms where the toilet is exposed vs water closets where the toilet is enclosed create a designated area for better hygiene and style.
History of Water Closets
The water closet has a long history. Early toilets were holes in the ground or chamber pots, often outside or in communal areas. The concept of a “water closet” started to take shape in the 16th century with the invention of the flushing toilet by Sir John Harington, a godson of Queen Elizabeth I. His design had a cistern and a flushing mechanism but it wasn’t widespread.
By the 19th century advances in plumbing technology made water closets more practical. The introduction of cast iron pipes and the development of sewage systems in cities like London changed the way we do sanitation. The term “water closet” emerged during this time to describe a small enclosed room with a toilet connected to the sewer system.
In the 20th century the water closet became a standard feature of modern homes. With porcelain fixtures, dual flush systems and compact designs water closets got more efficient and beautiful. Now they’re a part of bathrooms everywhere, function and style combined.
