So far no regrets but it’s only been done a month. We opted not to do a spa as we didn’t think it would get used. We did not do a heater either; we are in south jersey and the water hit 80 this week. We dropped some decent coin on thermal bluestone treads which I like, but, right now am wondering if I should’ve done concrete. I think I’ll be happier about this choice in a few years when there are no cracks in it! Our pool is 18x42, sometimes wonder if it is TOO big but maybe once we have people over I’ll feel differently. Also we did not do any decking. Putting sod in up to the bluestone; will see how this plays out.
