This emoji brings to mind Korea's "jjimjilbang" (Korean spa) culture. Beyond simply warming the body, it can also signify a social space for enjoying leisure time with friends or family.

In the West, it mainly symbolizes a luxurious spa for personal relaxation or wellness. In contrast, in the East, especially Korea, it's more often used to show the everyday scene of relieving stress at an affordable and popular jjimjilbang.
