Abstract: A bath-tub tray has arranged on the inner surfaces of its longitudinally extending walls (3,4) grooves (e.g. 11,12) intended to receive a clamping plate (19), having a lower part (21) arranged to be inserted through a slot (17) in the bottom (2) of the tray and to clamp against the inner surface of the bath-tub. Preferably, both end portions of the tray (1) are provided with grooves, slots and clamping plates, although it is possible to provide one end of the tray with a permanently fixed, resilient plate which projects from the bottom (2) of the tray.
