Bathroom zones have certain grades of IPxX fittings. As per the image below we will explain each of the zones, and how it all ties into IPXX, if your bathroom combines or overlaps then a higher risk level should be applied.

A man with a questioning look over an image of bathroom zones

There are four bathroom zones, 0, 1, 2, and 3, then anything outside of that are referred as Outside Zones.

Bathroom Zone 0

Zone 0 is in the bath or shower tray, if lighting needs to go there, all fittings must use a extra low voltage supply which is a max of 12v and also be rated at IPx7 which is entirely immersion proof.

Bathroom Zone 1

Zone 1 is the area above the bath or shower tray. Any fitting in this zone needs a minimum of IPx4. It will be protected against water spray from all directions.

Bathroom Zone 2

Zone 2 is 0.6m outside the bath and a height of 2.25m from the floor. A IP rating of at least IPx4 is needed.

Bathroom Zone 3 (Outside Zones)

Zone 3 is anywhere outside zones 0, 1 and 2 (subject to specific limits) and where no water jet is likely to be used. No IP rating is required in these areas.

Each zone plays an important role for which fittings you should get, should you have any questions regarding bathroom zones, please contact Chris on 01332 410240.
