A set of parts having a "U" shaped channel ( 11 ) and a side prolongation ( 12 ) are used to form the upper edge and channel in an overflow type swimming pool. The set of parts can include straight parts ( 1 a), corner parts ( 1 b), drainage parts ( 1 c), fitted steps, lane divider anchors, and curved edges. The upper surface of the prolongation slants toward the edge of the swimming pool at an angle of approximately 1 to 15 degrees and forms a base to place tiles to finish the appearance of the swimming pool. The parts can be constructed of ceramic, cement, stoneware, baked clay or other polymer.
