These steps for a swimming pool are noteworthy in that they possess, projecting from the inside of the recessed front face (1a), at least one solid part (1d) that acts as a backing or support produced directly by a process of injection moulding a plastics material for the production of the body of the steps, and the said rib (1d) appears as an extra thickness on the inside of the face (1a), in the thickness of which the fixing means (2) of a liner (3) can be engaged.
