Zone Information in Detail

 

Description of Zone 0

Zone 0 is the interior of the bath tub or shower basin (see Figures 701.1 and 2).

Description of Zone 1

Zone 1 is limited by:

(i)   The finished floor level and the horizontal plane corresponding to the highest fixed shower head or water outlet or the horizontal plane lying 2.25m above the finished floor

level, whichever is higher.

(ii)  The vertical surface:

a)      Circumscribing the bath tub or shower basin (see Figure 701.1)

b)      At a distance of 1.20m from the  centre point of the fixed water outlet on the wall or ceiling for showers without a basin (see figure 701.1(c) and (i).

Zone 1 does not include Zone 0.

The space under the bath tub or shower basin is considered to be Zone 1.   However, if the space under the bath tub or shower basin is only accessible with a tool, it is considered to be outside the zones.

Description of Zone 2

Zone 2 is limited by:

(i)                  The finished floor level and the horizontal plane corresponding to the highest fixed shower head or water outlet or the horizontal plane lying 2.25m m above the finished floor level, whichever is higher.

(ii)                The vertical surface at the boundary of zone 1 and the parallel vertical surface at a distance of 0.60m from the Zone 1 border (see Figure 701.1).

For showers without a basin, there is no Zone 2 but an increased Zone 1 is provided by the horizontal dimension of 1.20m mentioned in Regulation 701.32.3(ii)b) (see Figure 701.1(c) and (I))
