Hello. I am new to this group but have been perusing the forum for several days now, since deciding to remodel our pool built in 2008. We currently have SWG and flagstone coping on our pool, fire pit and spa, and a moss rock waterfall. The flagstone has deteriorated badly in several areas and also the rock waterfall is showing wear. So far, we have interviewed 4 contractors who each are encouraging us to convert our SWG to regular chlorine. We love the way the saltwater feels and you don't get that heavy chlorine smell, so we want to keep it. We are strongly considering travertine for coping on pool, spa and fire pit, as we have heard it is the most durable natural stone. Also replacing the rock waterfall with a stacked stone wall and stacked stone on spa and fire pit. I have researched this so much, I don't know what is what anymore. If we go with the travertine, is there a particular type that is more durable than others? Our home has Oklahoma wister on the outside which is why we are leaning towards natural stone. I am more concerned about the quality than the price as we don't want to do this again in a few years. We are not getting any younger...
