New in ground in CA - they just installed water line tile and when viewing result it's obvious that the coping tile overhang varies from 1/2" to 2"+ at various spots around the perimeter. It's a freeform pool with travertine coping which has been cut to match the pool shape. Unfortunately the overhang is not consistent nor is the coping edge particularly attractive due to the many pie shaped pieces comprising the final coping install (see pix). Meeting with pool contractor next week and I'm wondering if the overhang variation is typical in a quality pool build? Some variation on inside edge of coping is to be expected but how much roughness should be acceptable?
