I was looking into building my own inground pool, I really doubt that I will unless I buy land and build a new house, but you never know. Anyway, I seen several places showing people building the walls out of regular cinder blocks. I was just wondering if there was anyone on here that had any experience with this type of pool. At minimum I would like to have a 20' x 40' with 3.5-4' end for kids, with the other end sloping down to 8' or whatever is necessary to allow for diving from a diving board. Although, I would really like an L shaped pool to add an extra 20' x 10-20' to the shallow area. Thanks in advance for your knowledge!!!
