The working volume of the pool is the amount of water that is standardly contained by the product.
Usually, the working volume is indicated based on the occupancy of the pool at 80% of the maximum capacity. With such a fullness, there will be enough water inside for normal use and at the same time it will not overflow when the next person is immersed in the pool or when waves occur.
The capacity of the pool directly depends on the volume: the larger the tank, the more people will be able to swim in it at the same time. In addition, more capacious models are often also
deeper. On the other hand, a large capacity correspondingly affects the cost and puts forward increased requirements for additional equipment: a powerful pump, a performant filter, an efficient drain system, etc. are needed. Accordingly, it does not always make sense to chase large volumes.
In addition, it is worth noting that products with the same volume can differ markedly in size and, moreover, in shape. So in fact, the volume often turns out to be a secondary parameter, and it is easier to choose a pool in terms of length-width-depth.
