An extendible and retractable spa jet in the retracted position resides in the side wall of a spa or tub and is connected to, and operated by, the existing pressurized water and/or air supply. In the retracted position it serves as a conventional fixed jet. When desired, it may be pulled outwardly from the side wall of the enclosure and used as a hand-held massage device to achieve concentrated, intensified massaging action at localized areas of the body not possible with fixed spa jets.
