I am looking at the 20'6" x 40'6" grecian (octagan) shape polymer wall pools. hydrapools.com has the dig diagrams, but I don't understand them. Of the two type pool bottoms that I am considering, the square hopper bottom looks like its a straight vertical drop from the deep end of the pool to the 8' bottom. Is this possible with a liner pool? I thought they all angled toward the middle of the pool at the deep end, with no sheer 8' drops from the deck.
On the other hand, the contour bottom style looks like it has a smaller hopper and the sides seem to angle toward the middle of the pool. What are pros and cons of each?
Thanks, Webfeet
