Abstract: A hydromassage bathtub for domestic and therapeutic applications. The bathtub has a two level bottom wall defined by two successive surfaces sloping slightly towards the drain pipe area and joined to one another by a transverse ramp of slight extent, a front inclined wall having a centrally located depression facing the lower portion of the back of the user, an essentially vertical end wall opposite the inclined wall and two essentially vertically extending lateral walls. Longitudinal passages secured to the outside surface of the bathtub along the lower region thereof and extending essentially tangentially to the lateral walls, to the inclined wall and to the end wall, for circulating compressed air emanating from blowers. The compressed air is also distributed through inwardly extending branches connected to the lateral passages, the branches being located underneath the bathtub and following the transverse ramp.
