Hi..I'm new to the thread and need some advice. We are looking at doing a 18x46x 20x40 L shape pool. We have 5 kids and want a deep and separate shallow end for volleyball and game area. We are doing underliner steps that will take up 4 feet in the shallow area, so that leaves 36 feet off playing area? I'm getting nervous because everyone keeps telling us that is a huge pool. Now I'm thinking we should make it smaller. Any suggestions???
