A shower (or shower-bath, walk-in shower, steam shower) is an area in which one bathes underneath a spray of water.

The original showers were neither indoor structures nor man-made, but were common natural formations: waterfalls. The falling water rinsed the bathers completely clean and was more efficient than bathing in a traditional basin, which required manual transport of both fresh and waste water. Ancient people began to reproduce these natural phenomena by pouring jugs of water, often very cold, over themselves after washing. There has been evidence of early upper class Egyptian and Mesopotamians having indoor shower rooms where servants would bathe them in the privacy of their own homes. However, these were a far cry from modern shower facilities; they had only rudimentary drainage systems and water was carried, not pumped, into the room.

The first group of people to have showers that would be recognizable to a modern person were the ancient Greeks. Their aqueducts and sewage systems made of lead pipes allowed water to be pumped both into and out of large communal shower rooms used by elites and common citizens alike. These rooms have been discovered at the site of the city Pergamum and can also be found represented in pottery of the era. The depictions are very similar to modern locker room shower, and even included bars to hang up clothing. The ancient Romans also followed this convention; their famous bathhouses can be found all around the Mediterranean and as far out as modern day England. The Romans not only had these showers, but also believed in bathing multiple times a week, if not every day. After the fall of the Roman Empire and the rise of Christianity, practising what is today considered good hygiene became a religious taboo and was abandoned almost completely from the late Middle Ages until the Victorian era.
