My pool builder tells me the savings in cost to build will be $2000, but he mentioned that he could cut 6 inches off the perimeter of the pool all the way around and it will not feel like much of a loss. Do you agree? We are planning to build a free form pool with a straight away because we genuinely like to do laps. The length in the 800 sf pool would be about 42 feet. I wouldn't want to lose too much of that length, so your thoughts are appreciated.
