A bath for hydromassage, in particular for hydromassaging the bark, is described. The bath comprises a series of nozzles for delivering liquid under pressure, aligned longitudinally on the backrest thereof in a substantially median position. Said nozzles have associated with them control means for supplying them in succession with the liquid under pressure in one direction or in the opposite direction. This sequence is repeated cyclically for a predetermined period of time. The control means comprise a distributor which receives the liquid under pressure from a supply source and which is provided with a first substantially stationary member and a second member substantially movable with respect to the first member. The second member is provided with at least one opening designed to be positioned, as a result of displacement of the movable member, opposite openings of he fixed member communicating in succession with he series of nozzles. In this way the liquid under pressure is allowed to flow into the latter, supplying of the nozzles being perform d in one direction or in the opposite direction according to the direction of displacement of said movable member.
