A partially recessed, fully enclosed wall cabinet for storage of water closet personal items is disclosed. The wall cabinet described here is specifically designed to accommodate the size, shape, and quantity of personal items needed for access by a person sitting on the toilet. It uses empty space between wall studs to provide storage volume for personal items, but extends the storage volume slightly outward into the water closet area in order to enable storage of such items without deformation. The user may configure the dividers to provide a customized configuration of storage compartments. The outer doors of the invention keep all stored contents protected from general view as well as contamination, but allow simple access. The invention also enables exchange of the dividers for a trash receptacle for discrete, enclosed disposal of non-flushable items.
