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. Learn how to safely install electrics into bathroom zones, showers, or wet rooms using your bs7627 18th edition guide.
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. 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. 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.
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.

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 Requires a minimum of IP44.
Bathroom Zones IP Ratings Requirements - Satulight
This is the area directly above a bath and within a shower cubicle, up to 2.25M in height. Zone 2 Same as above, requires a minimum of IP44. Zone 1 is the area above the bath or shower tray to a height of 2.25m from the floor.
In this zone a minimum rating of IP44 is required and elements must also be protected by a 30mA residual current device (RCD) to protect the circuit. Zone 1 is the area directly above the bathtub to a height of 2.25m above floor level, yellow in the diagram. Note this is measured from the floor level, NOT the interior of the bath.
Zone 2 extends horizontally 60cm from the edge of zone 1, shown pink in the diagram. In addition to the zones, socket outlets are not permitted within 3m of the.
