Abstract:
1. A convertible spa stair apparatus comprising: two discrete treads; two unitary base pieces, each having two tread supports at different elevations thereon for supporting one of the two discrete treads, and wherein each tread defines a curve along a front longitudinal edge and a straight edge along a back longitudinal edge, and wherein each tread is reversible by being removed from the respective tread supports, and re-installed in a first and a second configuration to position the straight edge, and curved edge abutting a spa wall to accommodate spas having straight outer sidewalls and spas with curved outer sidewalls; and wherein the two unitary base pieces and the two treads each have friction fit connection features which matingly couple together to allow the respective treads to be installed in the first configuration and in the second configuration as desired by a user, and wherein the connection feature on each of the tread supports has a recess, and a connection rim extending about the recess, and wherein the respective treads each have a bottom surface, and opposite ends, and wherein each tread defines two coupling regions on the bottom surface, and proximate the opposite ends thereof, and wherein each coupling region has an inner connection ring, and an outer connection ring that releasably engage the connection rim of the respective tread supports.
