HOW MANY LITRES OF WATER ARE IN MY POOL?

One of the most important things you may ever need to know about your pool is how many litres (or gallons) of water are in it. In order to properly sanitize and balance your pool water chemistry, or ensure you're using the right equipment, you'll need to know just how much water your pool can hold.

Just use the simple pool volume calculator below that corresponds to your pool shape to instantly determine your pool water volume!

Round Pools

Your Pool Volume: TBD

Oval Pools

Your Pool Volume: TBD

Rectangular Pools

Your Pool Volume: TBD

Want to calculate your volume the old fashioned way? Our helpful chart below will show you the approximate volume of water your pool holds based on pool shape, size and average depth. Add your deep end and shallow end depths together and then divide them by two (in half) to get your average pool depth and find the correct volume.
