During 1958, the total number of persons using the bath was 28,967 (46,557 in 1957).
The average number of persons attending per day (wet or fine) was 188. The maximum
number at any one session was 350.
As this bath is uncovered, it is only opened for swimmers during the summer months—
May to September—and the attendance varies to a great extent according to weather
conditions. A drop in the total figures of over 17,000 from the previous year's figures is the
result of a summer which was abnormally wet and cold. The popularity of swimming has
been increasing in the Borough, and swimming is a most healthful exercise, so this big drop
in attendances is somewhat disappointing.
A paddling pool for young children is available in Cranleigh Gardens play park—the
capacity of the pool is 20,600 gallons and the depth from 3 inches to 12 inches; the water of
the pool is free running and is treated by continuous chlorination for hygienic purposes.
During the year the use of this pool continued to increase.
