An improved insulated cover is provided for removable mounting onto a spa or hot tub or the like to minimize thermal and evaporative losses, while additionally safeguarding against foreign objects and/or persons falling into the tub. In the preferred form, the insulated cover comprises a frame ring in combination with a structural membrane stretched across the frame ring with a peripheral margin of the membrane wrapped over the outer rim and radially constricted for retention thereon by a drawstring or the like. The constricted drawstring additionally secures an insulation plate or disk relative to the structural membrane and frame ring. The insulation plate fits with close clearance into the spa tub, when the frame ring is supported on the top of the tub wall. An outer insulation skirt may also be provided to project downwardly about the tub wall.
