The shape and dimensions of swimming pools

The figure and dimensions of a swimming pool are equally interdependent. The
primary use of the pool will be a main factor in decisive both shape and
dimensions
If the primary use is for exercise and swimming, then a quadrilateral shape
 is normally select. The length should be a simple fraction of 100 m, and the width
a number of swimming lanes which are usually to be 2.0 m wide (ASA for 25 m
pools)
The materials used in the construction of the pool shell will also influence its
shape. Pools constructed in insitu reinforced concrete can be of any shape, but the
cost of a free-formed pool would be very high due to the cost of the formwork,
compared with a pool constructed in sprayed concrete (shotcrete). But this cost
differential is influenced by the size of the pool, it being greater for smaller pools
than for larger ones. The smaller domestic and hotel pools, constructed in sprayed
reinforced concrete can be any shape, with little difference in cost between
rectangular and free-formed.
As these pools are likely to be used by children, non-swimmers and weak
swimmers, the provision of a safety step around the pool at a depth not exceeding
900 mm (0.9 m) below top water level is strongly recommended. This is a standard
feature of hotel pools in Switzerland
