A 15x30x54 pool (15 feet wide, 30 feet long, and 54 inches deep) holds approximately 15,000 to 16,000 gallons of water when filled close to the top. The exact number can vary slightly depending on the pool’s shape and how full it is, but for a rectangular pool with these dimensions, 15,200 gallons is a good estimate.
