When was the sink patented?

The modern kitchen sink was patented in the United States on December 12, 1883, by a man named G. H. H. C. H. Thiel. However, sinks in various forms have existed for centuries, with some early designs dating back to ancient civilizations. These early sinks were often made from stone or clay. The evolution of sinks continued over time, leading to the stainless steel and porcelain designs we commonly use today.
