Abstract: A variable depth swimming pool/spa can comprise a movable deck and a bottom. The movable deck can be movable relative to the bottom of a variable depth swimming pool/spa to provide for a variable depth of the portion of pool/spa that is accessible to a pool/spa user. The movable deck can be connected to the bottom of the variable depth swimming pool/spa via one or several legs. The one or several legs can be rotatingly connected to the movable deck and can be slidingly connected to the bottom of the swimming pool/spa. The rotational displacement of the legs can result in the vertical displacement of the movable deck. The legs can be connected to synchronizing arms that can interact with a synchronizing drive to coordinate the movement of a first leg with a second leg.
