Good morning, we just signed to have a pool built and they start this week. we initially contracted for a 17X35 curved shaped pool. After laying it out with string in our yard, it's looking kind of small and we are debating whether or not to go to 21X40. We currently have 2 girls 7 and 10 who will be swimming a lot and will be inviting friends over quite a bit. Include myself and my husband, we also have my mother and another relative that live with us who will also be in quite often. Add to that, my husbands son, daughter in law and 3 small kids. would anyone be willing to share their pool size for a family of let's say 6 with regular swimming guests? The reason we decided on the pool was to have all the friends at our house as the kids grow up to keep our eyes on them and to have nice pool parties in the backyard (we have a good size yard). I'm thinking we need it big enough for water floats as well. Thank you.
