Abstract: A paper towel roll dispenser has an enclosing polygonal shaped housing within which is mounted an access door which is movable from a closed position to an open position. To be mounted within the internal chamber of the housing is a post assembly which is comprised of an elongated post fixedly mounted onto a polygonal shaped base. The base and post are to be mounted within the internal chamber of the housing with the polygonal shaped base interlockingly connect with the housing in a non-rotative manner. A roll of paper towels is to be mounted in conjunction with the post with the free end of the roll of paper towels to be inserted through a slot in the housing and extend exteriorly of the housing. There is a first version of this invention that is adapted to be stood on end and a second version that is adapted to be mounted under a shelf.
