The towel hanger bar for the bathroom door creates extra space for your door and keeps your bedroom, bathroom, or kitchen clean and orderly. The behind-door towel rack is durable and stable, and it only takes up a little space. It is hung on the door with a solid hook. The maximum size of the 4-tier over-the-door coat rack is 1.88 inches, and the minimum is 1.57 inches. It is suitable for most door sizes. The board and hook on the top of the over-the-door bathroom organizer are detachable, which can bring you more storage space when installed. The staggered design makes the whole hang towel holder bathroom door look neater and is more convenient to hang things on. Use two suction cups to keep the back of the door storage organizer stable, and do not shake or drop it.
