Abstract: A shelf assembly has a horizontal toiletry article supporting tray with wedge-shaped brackets formed as depending extensions of the left and right ends of the tray. Vertical rear edges of the brackets abut a wall and angled front edges bear against a conventional towel bar to removably secure the shelf behind the bar and to elevate the tray to permit normal usage of the bar to hang towels. The rear of the tray has an upwardly extending flange which serves as a shelf back abutting the wall. Rods are provided on its left, front and right edges to present a raised lip to keep articles on the shelf. The tray, brackets and flange are preferably formed as an integral, unitary structure of acrylic plastic.

Abstract: A shelf assembly mountable on a towel bar that is spaced from a vertical wall, which includes a horizontal plate with a peripheral rim; a pair of spaced brackets detachably engaged to the bottom of the plate; the upper part of the brackets being resilient and fitting over the towel bar. An angle bracket is slidably mounted by a screw and wing nut in a slot in the underside of the mid-section of the plate so that a vertical leg of the bracket may be fixed in position to bear against an inside surface of the towel bar when the rear of the plate and the brackets bear against the external vertical surface of a wall to which the towel bar is fixed in spaced relation.
