Reply James Emmons Jesse Guralczyk Reply Randall Achorn Why not just buy a hot tub, Pools were made to cool off in not take a bath. Reply Lori Graham Gee! You’re right! I could quickly put that contraption together in let’s say…..3 years? Reply Gloria Wise Good thing my husband is an inventor/mechanic. This will be awesome for the month of April. Usually we can’t swim until end of July cuz water is still freezing. This is perfect solution. Hope it works for us!
