Abstract: This invention relates to a three-stream atomizing nozzle for use with a rewet shower. The nozzle has an air stream divider that separates the atomizing air from the source into three streams. The first stream is a straight air stream staying closest to and around the atomized water jet. The second stream is a swirl running around the first straight stream.

The mass profile can be tailored into a shape that is close to a square shape which is ideal for rewet showers as a square profile creates minimal coupling between adjacent zones.
