A convertible container assembly comprising a convertible container body. The container body includes angular series of conversion demarcations, defining an angular conversion section, and, optionally, at least one storage conversion demarcation, defining a storage conversion section. The angular conversion section includes a portion of a sidewall of the container body and a bottom portion of the container body. The angular conversion section toggles between an expanded configuration having a common horizontal upper rim and a compressed configuration creating a new container body support surface, angling the upper rim. The depth conversion section toggles between an expanded configuration as a container and a compressed configuration collapsing the container for storage. The conversion section can employ a single section or a series of sections, wherein the series of sections enable an accordion styled formation when collapsed.
