Traditional bathhouses are an important aspect of modern Korean culture. These jjimjilbang (jjimjilbang) are literally "warm chambers," and they are where residents come to unwind, hang out, and partake in a variety of health and beauty routines that go far beyond a short bath. Grandmas and young couples equally visit a Korean bathhouse. In fact, according to some researchers, the bathhouse is becoming more popular with each passing year. Modern-day Korean bathhouses are starting to resemble their traditional counterparts but with some key differences. They now often include saunas as well as warm baths, and some offer body treatments such as massages or wraps. Some also include rooms with hot tubs or even snow cones! The jjimjilbang has become yet another place for people to socialize and have fun. Bathhouses first came to Korea in the 19th century. At that time, they were called yangtae haebal (양태해백라), which means "hot spring hotel." These hotels were places where farmers going about their daily business could relax after a long day's work in the fields. They offered a simple but effective form of entertainment by waying visitors how to play Chinese chess. Many farmers became great guests of honor at these hotels because they needed rest after a hard day's work! These days, most Korean bathhouses operate on a membership system.
