toilet

Also known as: lavatory, water closet

Quick Summary

A toilet is a fixture within a building's plumbing system designed for the removal of waterborne wastes. Historically, waste disposal has been a significant challenge for civilizations, with early systems being rudimentary and often leading to the spread of disease. The modern toilet, or water closet, evolved significantly during the 19th century with advancements in sanitation and the development of underground water and sewage systems.12

The word "toilet" itself has an interesting etymology, originating from the French word "toile," meaning cloth. It evolved from referring to a cloth used for grooming to the articles on a dressing table, then to the process of grooming, and eventually to the room where these activities took place. By the late 19th century, the term was transferred to the fixture itself.3

Composting toilets offer an alternative, waterless system that decomposes human waste into a nutrient-rich material, reducing water consumption and costs associated with traditional sewage treatment.4
