Abstract: A portable container has an upright service tower in the form of an elongated support post with one end secured to the bottom of a water-filled container adjacent its side wall, while an intermediate section is secured to the upper side wall of the container. A suitable spacer is disposed between the container side wall and the service tower so as to slightly incline the support post toward the center of the container to thereby stabilize both the support post and the container. A handle pivotally carried by the container is adapted to snap-lockingly engage the post to securely attach the container to the support post. The post has a plurality of means for carrying articles, such as brushes, bottles, a hose, soaps and the like.
