Various embodiments of the present invention relate to a dispensing system for use in lavatories. The system may include a container, a mount, and optionally, a conversion module. The container may have an attached dispensing mechanism and a projection that is adapted to fit into a receiver on the mount or conversion module. The receiver may be adapted to engage the projection on the container. The assembled system secures the container into the mount and allows the container to be rotated to a proper orientation while it is secured to the mount.
