A thermostatic mixer device for sanitary appliances, includes: a cartridge envelope; a distributor bottom member with intake openings for cold and hot water, a delivery opening for mixed water, and elements for controlling and intercepting the delivered flow rate; a mixing member located inside the envelope, forming a cylinder, control openings and passageways for directing hot water and cold water from the intake openings to the respective control openings; a distribution slide valve, sealingly sliding in the axial direction within the cylinder of the mixing member, and cooperating with the control openings in order to partially shut the control openings in opposite senses; a thermometric element for displacing the distributing slide valve against the action of a return spring; and control elements for establishing the temperature desired for the delivered mixed water. The envelope and mixing member form, in a single piece, a sole containment and mixing member which, with its outer portions, forms the envelope containing the mixer device, with its inner portions forms the cylinder cooperating with the distribution slide valve and the control openings, and by cooperation of the outer and inner portions determines the passageways.
