Hi, anyone install a lap pool at their home? We're in southern NH, wife wants one in our backyard, which has the room and good southwest exposure, although land slopes downward a bit. Thinking of something 12' or 15' wide and maybe 50' long, not deep maybe 4-5' deep. Doubt they have commercial pools of this size already constructed (if they did, great!), so I assume it'll have to be custom built. With shorter season up north in southern New Hampshire, would like to extend season with some kind of heating option, maybe just solar cover would help and be cheapest. I have no idea what this might cost, any backed by experience estimates? Any ways to reduce cost if, let's say, $50k or more? She said she doesn't want a current pool where you swim against the current. Also, she wants salt water filtration (not chlorine).
