How many gallons in a 25x15 oval pool?

Answer 1

The perimeter of a pool that is EXACTLY 15' wide by 30' long is 77'1". You have to be careful though as a lot of pools are not made exactly to those specs. Often they are a little bit smaller which effects the perimeter a lot.

Answer 2

A 15 by 30 foot swimming pool can be any depth. As a constructor of gunite or concrete pools I could make any size of pool any depth from 6 inches to 10 feet or more. The size of a pool has no direct effect on the depth. We did pools for exercising horses that were 10 feet deep for the entire pool. A pool of any size for normal use will have a shallow end, usually 2 and 1/2 to 3 feet in depth and will graduate to 6 feet for swimming or 8 or more feet in depth for diving. With fiberglass or vinyl liner pools the depths are established by the manufacturer and you will have to choose from the sizes offered what will best suit your needs. I believe some of the manufacturers may make custom sizes per the purchasers request, but the price will be significantly higher for a special order.
