A:AnswerI researched this before I purchased and found 78 gallons. I think that came from the manufacturer's website. The pool does have a drain plug on the bottom. One time the drain plug was uphill (slight slope where we place the pool) and I ended up lifting 1 side of the frame to dump the water.
