Just starting to look into having either a vinyl or gunite pool. I live in western Suffolk County, Long Island. We have a large yard - 2 acres. I'm thinking a 20 x 40 rectangle. Steps across the whole low end (4 ft?) . Possibly deep water bench. I would like a deep end @ 10 ft. I really want an automatic cover but I don't know if you can have one with a swim bench. Heat pump. I think gunite might be way too expensive here . I'm thinking @ 45ish for just pool. Am I way off??
