摘要

The unit has a one-piece plate-shaped shower body (1) that is made of wear-resistant alloy e.g. iron alloy, where the shower body is formed in X, Y, Z planes in a planar manner and is formed in a rectangular manner. The longitudinal and the transverse sides (2, 3) are formed by rounded sections (5,6, 7, 8) that are merged into each other. The body is provided with rounded surfaces (4, 9) that are merged into each other and with a recess (10) in an area of a front surface of the body. The edge surfaces (11, 12) of the body are formed in concave manner.
