So….entering into my pre-geeper years (62), and looking to rest / massage these tired muscles. Scoping out a hot tub. I can’t find a legit answer on salt water tub vs conventional. Those who sell salt water say they are THE shit. Those who sell conventional say salt water tubs ARE shit. Anyone here have any experience with either. Looking at Caldera and Cal spas. 2-3 person. No sex parties with the neighbors in a 6 person…..just me and the Mrs.
