    (54) Manufacturing method and bath tub made of composite material with improved supporting frame produced by such method


    (57) A method for manufacturing a bath tub made of composite material comprises the steps of moulding the tub (11), applying a first substantially annular frame member (12) around its edge, applying a second substantially flat frame member (15) to the underside of the bottom of the tub (11), and interconnecting said first and second with third frame members (14). Said method comprises a further step of applying lateral wall elements (34) around said tub by removably coupling said wall elements to at least said third frame members. The tub manufactured according to such method therefore comprises, in combination, a circumferential frame member (12), a flat frame member (15) on the bottom and frame members (14) to connect them together. Lateral walls 34 can be applied by fitting them into springs 25 and into coupling means 33.
