The water fountain is made by Henri. It retails for about $3500, but we found this one tucked in the corner of a nursery after Hurricane Katrina. Got it for $700. We actually bought it before the house was finished and hauled it around for a month in the back of my truck (over 1000 lbs.).
I did wear a wetsuit the first time I got in at around 70 degrees. I am used to SCUBA diving in cool water so the 70s is no big deal. A little while ago the water temp was 82; very nice.
