A hydromassage bathtub with ultrasound micromassage system comprising a plurality of ultrasound emission devices (13, 113) distributed over the walls of the bathtub. The ultrasound emission devices (13, 113) comprise means (23, 26; 118, 125) for orientating the direction of emission of the ultrasounds into a wide beam, at least 10 cm. wide at a distance of 20 cm. from the source. In case of conical beam, the means orient the beam into a solid angle of not less than 30° and advantageously at least 50°. With one ultrasonic emitting element (24) inside the emission device the emission beam obtained is superior to the natural width or divergence of said element.
