A bath shower mixer is a type of plumbing fixture that combines both a bath tap and a showerhead into one unit. It is commonly used in bathrooms where there is limited space and a separate shower enclosure is not practical. The bath shower mixer typically has two handles or knobs, one for hot water and one for cold, that are used to control the flow and temperature of the water.

The showerhead is attached to the bath spout, and when the diverter is activated, the water is redirected to the showerhead. Some bath shower mixers also include a handheld showerhead that can be detached from the unit and used for more flexibility in showering.

Bath shower mixers can be mounted on the wall or on the bath itself, and they come in a variety of styles and finishes to match different bathroom designs. They are a convenient and space-saving solution for homes with smaller bathrooms and can provide both a relaxing bath and a refreshing shower experience.
