Abstract: A retractable trackless spa enclosure includes at least two sections, a first section being slightly smaller than a second section. The first section may be retracted into the second section in reverse telescoping fashion. Both sections are mounted on wheels so that the spa may be more easily moved. Both sections of the enclosure may also include a sliding door for access/egress. In addition, the front end panel of the front section is pivotally mounted on rollers that move within a track. The pivotal mounting allows the front end panel to be rotated in its frame, so that it can be moved to a position horizontal to the ground, thereby providing sufficient clearance for the enclosure to pass over the spa. When the enclosure is retracted, the front end panel can be moved to a position adjacent the end wall of the rear section, so that an open-ended alcove is formed. The frame of the structure is formed from extruded aluminum, and is therefore very lightweight.
