Abstract: A toothbrush holder assembly and method includes a hinged container housing with two hinged halves that cooperate between open and closed conditions. In the open condition, the hinged halves of the container housing are swung open to allow a toothbrush head to be inserted into or removed from the housing. In the closed condition, the housing is adapted to store the toothbrush with the toothbrush head enclosed between the opposing hinged halves and with the neck of the toothbrush extending out from the housing through an opening. The housing is secured to a base that is also coupled to two separated suction cups. The assembly is particularly adapted for vertical storage of a toothbrush when oriented with the suction cups vertically spaced such that the container housing halves open and close horizontally.
