An adjustable container holder includes two rods that can be connected by a tube, where the tube and the two rods can together embrace a container. Each rod is attachable to a L-shaped support bracket by means of a clamp, where the rod is sandwiched between the clamp and the L-shaped support bracket. Each of the L-shaped brackets has apertures therein for mounting the bracket to a surface such as a wall or a floor. The tube is adjustable so that the width of the container holder can be changed. Once the width of the container holder is adjusted, the container holder can be fixed by mounting the L-shaped brackets to the surface.
