Abstract: A method of manufacturing a spa including molding a plurality of side walls, cutting utility openings in said side walls, thereby producing cutouts which are then secured to the side wall and cover at least a part of the utility opening. The cutouts may cover the same utility opening from which it stems or a different utility opening from the same side wall or different side wall. The side walls may be made integral to the basin, such as in rotomolded spas, or made separate from the basin. Certain cutouts are rotated so as to have a major dimension of the cutout cover a minor dimension of the utility opening. Certain cutouts are trimmed from their initial size so as to cover a utility opening smaller than the utility opening from which it stems.
