To go to an aqua PT place, it costs $100 per time and out of pocket. My husband for an exercise pool that’s actually about 6x10 and 4-5 ft tall. Somehow you attach yourself to a hanger on the top, and it allows you to swim in place. I’d like a hot tub that also has a swimming feature. Big difference in price. The one my husband found is about $2,000. The hot tub/swimmer is $10,000 plus. Has anyone used these, and did it really help?
