A number of different activity s
paces are shown in the diagram (See
Illustration 1
):
space occupied by the appliances itself, a
dditional space requir
ed by the user and
further space for their own belon
gings or circulation within t
he toilets. In many cases,
these latter spaces may overlap on occa
sion. Common sense will dictate when this
is appropriate and when it is not.
Placing the appliances in order of use si
mplifies the circulation and reduces the
distance travelled by the user. Using
sensor-operated applianc
es should encourage
hygiene.
It is difficult and costly to insulate the toilets acoustically and this problem can be
resolved by planning isolation as much as possible.
No unsupervised installation can prevent
vandalism. Even with
the most vandal-
resistant appliances, an unsupervised fac
ility will eventually become sub-standard.
In most cases, facility engineers and clean
ing attendants play an important role,
which will result in well-maintained toilets. However, all designs should allow for
individual items to be replac
ed. Pipe work, traps and electrical supplies should be
concealed for aesthetic and hygiene reason
