A tube stand has a base with an interior space for receiving a spent portion of a tube, a panel removably attached to the bottom of the base, and a sleeve removably attached to the cover of the base. The sleeve preferably has a pseudo-conical shape with a circular transverse cross-section at its top end and an elliptical transverse cross-section at its bottom end. The sleeve provides vertical support for the upper portion of the tube but is advantageously removed to allow the base to still neatly hold the tube in an accessible manner when it is nearly empty. An alternative embodiment uses a lid with wedge blocks having V-shaped ramp surfaces that guide the end of the tube into a slot, the ramp surfaces providing lateral support for the tube.
