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.
Please note: this is a guide only and not definitive. Always consult a licensed electrician when making decisions around lighting installation.
