Abstract
Pool stair assemblies having stair structures fabricated from plastic foam are provided. The stair structures include protective tread sheets and protective riser sheets and a vinyl pool liner mounted over the stair structure, tread sheets, and riser sheets. The stair structure, which may be buoyant, is retained in a pool by the weight of pool water on the liner and stair structure. Aspects of the invention overcome the disadvantages of conventional pool stair assemblies and ladders positioned on top of pool liners. Other related pool structures, methods of installing stair assemblies, stair structures, and methods of fabricating stair structures are also disclosed.
