That depends on a few different factors. The main factor being the size of the pool, or more accurately the length of the pool. To meet the current code requirements for the slope of the pool floor, which is quite different than it was several years ago, the pool would have to be rather long to achieve a 6′ or greater depth, making it cost prohibitive in most cases. Another reason for shallower pools is the trend with today’s pool; in a shallower pool, more of the pool becomes usable, and that’s what people want. Another reason is that some of the areas we work in have a very low elevation which means when we dig the pool there will be underground water present that makes it more difficult to construct the pool. Building the pool shallower avoids this situation in most cases saving the homeowner the added expense. Most pools today are built from 3′ in the shallow end to 5 or 51/2′ in the deep end and occasionally they are built a little deeper.
