We have an above ground Michael Phelps Momentum Swimspa. It is 20 feet long, 4 ft deep and 8 ft wide. It has the divider for the hot tub which has its own heater and then the pool with the propulsion jets on the other side with its own heater. If you want more info you can email me at
jane032657@aol.com It is huge and you need a very large area to place it. I use it every day for both the hot tub and for water excercises. It is a very important part of my daily routine. It is costly to heat so I strongly suggest being fully committed to using it if you were to purchase a swimspa of this size. I am grateful every day not only to live in The Villages, but to be able to use this for my overall health and well being.
