My husband and I built our own pool from a kit 3 years ago. I would NOT do it again. However....we had a 16 X 32 IG with deep end and diving board. Our daughter loved the shallow end to do hand stands and stuff. Our shallow end was small because of the slant to the deep end. To be honest, my 14 year old was 11 at the time and loved the diving board. I stayed in the shallow end, but we didn't have much of one. That sucked. I am only 5 feet tall, and I hate deep water. We are now doing a 14 X 28 Lagoon style vinyl IG pool 3.5 to 5.5 feet deep with a swim out. It is just perfect for us...not too big... not too small. To use it 4 or 5 months out of the year, it is just big enough. We are investing more in concrete, stamped and colored. Plus, we are doing a salt system this time.
