It is formed on the basis of a glass-fibre-reinforced polyester body 1 in which there are a large number of holes 2, specifically a number of holes in excess of 220, which form mutually independent functional groups 3-4-5-6- 7-8 placed in communication by a common manifold (collector) 12 via similarly independent conduits, provided with individual electrovalves 13. The water is recycled from the bathtub to the manifold 12 via a pump 14, and an electronic circuit 16 controls both the electrovalves and the pump and the other bath-tub accessories, such as a resistance element 17 for generating steam and a blowing device 18 for generating air. The exit holes 2 are located in the bottom of grooves 9 which prevent their accidental blocking, and the fluid conduits 11 are obtained by means of complementary channelled pieces 10 which are fixed to the outer face of the body 1. <IMAGE>
