you arent going to save any money by buying a pool from one place and trying to get a builder to install it for you. not to mention fiberglass is unforgiving and any issue will result in you dealing w the seller on a warranty, and they will point the finger to the installer. call some pool companies and see what you can get for a budget job, depending on how fancy or simple you wanna keep it you can get a pool for a decent price. Ive seen many post on here for basic steel wall pool and a simple concrete deck for a reasonable price. it costs twice as much to install and complete the pool as it does the cost. so if your looking at a 12k dollar fiberglass pool plan on 20-25k for the install, equipment, plumbing, electrical, concrete. theres SO much more than just the pool
