Hydromassage carpet formed by an envelope (10) obtained by means of two sheets of suitable soft and flexible material, which are joined together with a peripheral weld (20) and further welds effected on the inner part thereof, defining two distinct ducts, a first sealed duct ??? filled with a suitable fluid so as to form practically a mattress and a second duct (32), connected through a feeding pipe (4) to a compressed air generator and provided at its upper part with holes (5), the compressed air generating in the bath the desired hydromassage effect by leaving them. On the inner part of the peripheral weld (20) are effected several circumferential toes (311), at whose centre relevant central welds (312) extended for a sufficient surface being provided, thus obtaining a correspondent plurality of toroidal elements (T), whose lower part forms, when resting on the bottom (F) of the tub, a cavity (V) fully similar to that of a sucker and carrying out the same function thereof. The adjacent circumferential toes are interrupted for short portions (313-315) and the ends of the interruptions are directly connected together or by further suitable toes (316), so as to form together with the carpet portions inside thereto a sole duct (31) and thence a second duct (32) together with the portions outside thereof.
