Bathroom Lighting Zones In Australia

To make sure you always choose the correct lighting for your bathroom, we have created an easy step by step guide. This is based on the AS/NZS 3000 Lighting Standard.

Zone 0

Includes:
- For baths: inside the bath.
- For showers: shower walls, shower floor and inside the shower cubicle.
- For showers over baths: shower walls, shower floor, inside the bath and below the shower head.
Minimum requirement: lights with IP rating IP67 and maximum voltage of 12V.

Zone 1

Includes:
- For baths: the vertical area from the rim of the bath, up to 2.5m above the floor.
- For showers: from the top of the shower cubicle, up to 2.5m above the floor.
- For showers over baths: 1.2m radius out from the shower head, up to 2.5m above the floor.
Minimum requirement: lights with IP rating IPx4 or above (if showers/baths are communal then this rises to IPx5).

Zone 2

Includes:
- For baths: 0.6m outside the bath, up to 2.25m above the floor.
- For showers: 0.6m outside the shower, up to 2.25m above the floor.
- For showers over baths: 0.6m outside the zone 1 radius, up to 2.25m above the floor.
- For sinks: 0.6m radius around the sink.
Minimum requirement: lights with IP rating IPx4 or above (if showers/baths are communal then this rises to IPx5), or 12V lights, or lights recessed into ceiling.

Zone 3 / Outside Zone

There is no minimum requirement (if showers/baths are communal then this zone requires IPx5 rated lights). Nevertheless, we would strongly recommend IP44 rated lights.
All outlet sockets need to be inside this zone.
