I'm looking to build a classic rectangular pool. But since most builders price based on perimeter sq ft, a rectangle is not the most economical shape. Furthermore, for a given perimeter, you get more area as you get closer to a square. For example, a 16x32 pool has 96 perimeter feet and 512 sqft of surface area. But a 24x24 square pool also has 96 perimeter feet but 576 sqft surface area ... about 12% more area for roughly the same price.
My question is aesthetics related. I'm told a CLASSIC pool always has length 2x it's width. So 16 x 32 is a good design ... likewise 18 x 36 is pleasing to the eye. Does anyone have experience with squarish designs? Will something like 20x28 will look out of proportion?
