Bathroom Zone 1 Height

Zone 1 is the area above the bath to a height of 2.25m from the floor. If the fitting is 240V a 3oma residual current device (RCD) must also be used to protect the circuit in this zone. Zone 1 in a bathroom refers to the area directly above the bathtub or shower tray, up to a height of 2.25m.

This zone has the highest risk of exposure to water and requires fixtures with a high level of protection against moisture.

Bathroom zone 1 is the area above a bath or shower to a height of 2.25m from the floor.

In this zone, lighting with a minimum rating of IP45 is required but it is generally accepted that IP65 should be used to ensure safety. Equipment is either in a zone or outside a zone and this can be easily determined by measurement. The height of zone 1 and zone 2 are limited either by the horizontal plane corresponding to the highest fixed shower head or water outlet, or the horizontal plane lying 2.25 m above the finished floor level, whichever is higher.

Zone 1: The area above the bath or shower up to a height of 2.25 from floor level. Zone 2: The area reaching 0.6m outside the bath's perimeter, up to a height of 2.25m from the floor. Many experts in the field also recommend considering the area around a wash basin, within a 60cm radius of taps, as Zone 2.

Bathroom Zone 1 This is the area directly above zone 0 (which is the outer edge of the shower basin or bath) extending to the horizontal ceiling or 225cm from the floor, whichever is lower. If the shower head is higher than this then the zone extends to a line horizontal with it. Zone 1 Applies to the area around the bath or shower up to a height of 2.25m above the floor and at a radius of 1.2m from the water outlet.

A minimum rating of IPX4 is required. If the fitting is 240V a 30mA residual current device (RCD) must also be used to protect the circuit in this zone, i.e. SELV with the transformer located beyond zone 2.

If there is a likelihood of water jets being used. Zone 1: The area above the bath or shower up to a height of 2.25 meters from the floor. A minimum rating of IP44 is required, but IP65 is recommended for added protection.

Zone 2: An area stretching 0.6 meters outside the perimeter of the bath and to a height of 2.25 meters from the floor. Fixtures should have a minimum rating of IP44. Bathroom Zone 1 Zone 1 is the area above the bath or shower tray to a height of 2.25m from the floor.

Any fitting used in this zone must have a minimum rating of IPx4*, which means it is protected against water spray from all directions.
