Which zone is located at the top of the shower, above a bath or around a sink?

• A. Zone 0
• B. Zone 2
• C. Zone 3
• D. Zone 1

Answer: (D)

In bathroom electrical safety, zones show where water exposure is likely and what protection is needed. The area directly above the bath or shower tray, up to about 2 meters high, is Zone 1. This is the space where spray and splashes can reach, so it requires equipment with appropriate protection and installation practices. Zone 0 is inside the bath/shower itself, Zone 2 surrounds Zone 1 and extends up to 2 meters high and 0.6 meters outward from Zone 1, and Zone 3 covers the remaining room area. So the area at the top of the shower is Zone 1.
