Bathroom Zones Explained: Where Can You Legally Put a Plug?
Making a Splash? Why Your Nelson Bathroom Reno Needs to Master the "Zone"
Imagine you've picked out that gorgeous backlit LED mirror for your Nelson home. You've got the dream tiles, the rainfall showerhead and the perfect vanity. But as you go to mark the spot for the power point, you pause. Can you put a plug there?
In New Zealand, water and electricity are a high-stakes combination. Working through the AS/NZS 3000:2018 Wiring Rules isn't just about following the law; it's about making sure your morning routine doesn't include an unexpected shock. Whether you're upgrading a classic villa in Tasman or a modern apartment in Nelson City understanding bathroom electrical zones NZ is the secret to a safe, stress-free renovation.
At Mako Electrical, we believe your bathroom should be a sanctuary, not a puzzle of safety hazards. Let's break down the "no-go" zones and the "sweet spots" so you can plan your kitchen and bathroom upgrades with total confidence.
Key Takeaways
Zone 0: Inside the bath or shower—Zero chance for any plugs or switches.
Zone 1: above the bath/shower (up to 2.25m)—No sockets allowed.
Zone 2: 60cm outside the edge of your bath or shower—Safety first; usually for special shaver sockets or protected equipment.
Safety Switch: All bathroom circuits must have RCD (Residual Current Device) protection.
Expert Help: Always hire a registered electrician to ensure your renovation meets NZ standards.
Zone 0: The "Wettest" Area
Zone 0 is the literal "splash zone." It includes the interior of your bathtub or the base of your shower tray.
The Rule: You cannot install any power points or switches here.
What's Allowed: very specific low-voltage (12V) lights that are waterproof (rated IPX7).
Why it matters: Even a small amount of moisture inside a high-voltage fitting here is dangerous.
Zone 1: The "Vertical" Space
Think of Zone 1 as the column of air above your bath or shower reaching up to 2.25 metres from the floor.
The Rule: Still a "no-plug" area.
What's Allowed: This is where your ventilation systems and specific water-resistant lights go. These must have a rating of at least IPX4 (splash-proof) or higher if you have a powerful shower jet.
Zone 2: The "Safety Margin"
Zone 2 is the 60cm wide area that wraps around the outside of your bath or shower. It also includes the space around your vanity sink (a 60cm radius from the tap).
The Rule: You cannot put a standard 240V power point here unless it has specific protection and enclosure in a cupboard.
The Solution: This is the perfect spot for a dedicated shaver socket. These have special designs to ensure safety near water. For everything else, it's best to move it just a few centimeters further away into the "Outside Zones."
The "Safe Zone" (Everything Else)
Once you are more than 60cm away from the edge of the bath or shower, you are in the clear! This is where you can (and ) install your GPOs (General Purpose Outlets) for hair dryers electric toothbrushes and heaters. In New Zealand though, an RCD at your switchboard must still protect these to keep you safe from any faults.
