Our 20x34 pool is only 16' at the widest point (coping-to-coping). We thought the builder made a big mistake, since he had admitted to making an error in the shallow end that required a special "custom" liner. The liner was manufactured by Latham Plastics, the parent company of Kafko. When I called Kafko this morning the person I spoke with said the pool is actually 16' wide.
