A step assembly for a swimming pool, includes a unitary, one-piece, molded plastic, stand alone, lower step section including two steps, an upper platform at least as high as an uppermost one of the steps, a first supporting structure for supporting the two steps and the upper platform on a ground surface as a stand alone unit without any further supporting structure, a first hollow chamber defined between the first supporting structure, the two steps and the upper platform, and a first opening in the first supporting structure permitting access to the first hollow chamber; a unitary, one-piece, molded plastic upper step section including an upper step at a height greater than the upper platform, a second supporting structure for supporting the upper step on the upper platform, a second hollow chamber defined between the second supporting structure and the upper step, and a second opening in the second supporting structure for permitting water access to the second hollow chamber, the upper step section having dimensions less than the first opening so as to be inserted through the first opening when disassembled from the lower step section and so as to be entirely removably positioned in the first hollow chamber in a disassembled position for storage and shipping; and a securing assembly which removably secures the upper step section on the upper platform of the lower step section in an assembled position.
