When standing at the shallow end of the pool, looking toward the deep end; if the step is on the right, it is a right hand step and vice-versa.
If your step is on the long side of the pool you will need to determine the step offset from the end of the pool. To do this, measure the distance from the edge of your step to the end of the pool. To make it more exact you can draw a continuation line from the end of the pool outward past the step. Then just measure the distance between the line drawn and the edge of the step.
Generally step off sets will be either 0" (Flush), 6", 1', 2' or 4'.
