Im researching liners for my upcoming DIY pool. My local pool builder suggests 28 mil wall and a 20 mil bottom. They say the wall should be thick so the stretch is minimal at that point and will not allow the patterns to distort, the thinner bottom allows for it to stretch better into the corners for a smoother bottom finish.
Is this legit or are they just trying to sell me what they personally sell?
