The present invention provides a housingless liquid soap dispenser, comprising: a) an elongated chamber in which liquid soap is contained, wherein the length of the chamber is at least 25 cm and its width or diameter is ranging from 28-45 mm; b) a shoulder protruding laterally from the chamber at an upper end thereof; c) a neck portion extending upwardly from the shoulder; d) a manual pumping device fitted on top of the neck portion and in fluid communication with the chamber; and e) a discharge tube extending from the pumping device for dispensing a dose of liquid soap from the chamber. The shoulder has a slanted profile for enhancing the stability of the dispenser after its installation in removable abutting relation with, but not coupled to, a planar support surface of a countertop or a sink, such that the shoulder rests on top of the support surface while the chamber is inserted by a maximum extent through an aperture formed in the support surface.
