Zone 2 in bathroom electrical zoning is best described as which area?

• A. In a bath, shower base or sink
• B. Top of shower, above a bath or around a sink
• C. 0.6m away from the shower, bath or sink
• D. Outside the bathroom

Answer: (C)

In bathroom electrical zoning, safety margins are used to decide where certain fittings can be placed based on exposure to moisture. Zone 2 is the area just outside the immediate splash zone around a bath or shower. It extends 0.6 meters horizontally from the edge of Zone 1 and up to a height of 2 meters above the floor. So it’s not inside the bath, nor directly on top of the shower (that’s Zone 1), and it’s not outside the bathroom. The option describing a space 0.6 meters away from the shower, bath, or sink captures this boundary correctly, since Zone 2 sits just beyond the Zone 1 boundary within the bathroom. This distinction helps determine what protection level or IP rating equipment must have when installed there.
