A shower (also called shower bath) is a device for washing, typically consisting of an enclosed area and an overhead nozzle. To use a shower, a person stands in the enclosed area while the nozzle sprays water down on the body. Showers are primarily used for hygiene and washing purposes and are often installed in bathrooms.

The practice of using a shower to promote healthy hygiene practices goes back at least to the time of the Greeks in 300 B.C, as evidenced by extant vases and murals.[1]
During the Scottish Enlightenment, Lord Monboddo showered every morning with cold water on his front porch to emulate the Greeks, and professed his belief in the practice as healthful;[2] his habit, while considered eccentric, was well publicized with the intelligentsia of that era. Another step that led to the further popularization of showering practices was in 1879 when the Prussian military installed showering rooms in their barracks.
