Years ago, we purchased a hot tub from Water World. At that time, Water World also designed and constructed an incredible deck for us. When we moved to a house with a pool a few years ago, we got all sorts of fabulous advice from Water World. We regularly take samples from our hot tub and pool to them and get prompt feedback on what (if anything) we are required to do for our water. Last year, we purchased a winter pool cover for our pool. Water World came and installed it and we've never had a problem. We hire them annually to open and close our pool too. We've had multiple wonderful experiences with Water World and wouldn't hesitate to recommend them.
