For most people inground swimming pools are undoubtedly better than construction pools. From the ease of installation, to lower initial costs and running costs, there exists a slew of reasons to prefer built in pools over construction pools. But for people who want a really big pool, it can be used as a prefabricated pool. This is true for sports venues and large hotel pools. In those cases, it might be better to opt for a construction pool. But except for these special cases, for most people prefabricated pools are the better choice.
