Abstract: An in-wall retractable water hose assembly for retracting and storing a water hose, having a housing located within a dwelling and an insulated front access door for providing access to the hose from outside the dwelling. A reel assembly is mounted within the housing on which the water hose is spooled, and a motor connected to the reel assembly effects rotation of the reel. A power box is positioned within the housing and has a power switch in communication with the motor. A movable casing is mounted on the reel assembly, the casing having a channel for accommodating the water hose. Movement of the casing along the reel assembly determines the positioning of the hose and maintains an even distribution of the hose along the reel. A stabilizing bar prevents wobbling of the casing during retraction of the water hose.
