A step for ingress and egress from a swimming pool and/or a spa includes a tread including opposing side edges, a riser coupled with and extending substantially perpendicular from one of the side edges of the tread and an upper flange substantially perpendicular to said tread and coupled with and extending upwardly or downwardly from one of the opposing side edges of the tread opposite the riser. The upper flange is configured to be coupled with the riser of another step or a wall of the swimming pool or spa to form a stairway. |
