For an individual session
Dimension of the pool: Minimum 2m² (4 x 7 m recommendable).
Depth: Between 1m and 1.50m.

For a group session
The dimensions of the pool will naturally determine the viable size of the group.
You can use the same data for the individual session as a reference, counting a minimum of 2m2 per pair of participants.
Exclusive space is not needed, it can be kept open to be used by other customers.
