Bathroom Electrical
The things to understand and discuss with your electrician. Pricing is shown per country; regions marked "being researched" are coming soon.
Key things to plan
Wet-Area Zones
Bathrooms are split into safety zones based on distance from water. Each zone limits what fittings and outlets are allowed and what IP rating they need. Your electrician designs to these.
Advantages
- Keeps electrics away from water
- Defines safe fitting placement
Considerations
- Restricts where points and lights can go
- Must be planned before lining the walls

RCD / Safety Switch Protection
A residual current device cuts power in milliseconds if it detects a fault — essential anywhere water and electricity are close. Bathroom circuits must be RCD protected.
Advantages
- Life-saving shock protection
- Required by wiring rules
- Protects the whole circuit
Considerations
- Must be fitted and tested by an electrician

Power Points (GPOs)
Outlets must sit the required distance from basins and showers, and any near water need extra protection. Placement is governed by the zone rules.
Advantages
- Power for shaver, toothbrush, heated towel rail
- Convenience at the vanity
Considerations
- Strict placement rules near water
- Limited positions in a tiny bathroom

Off-Grid 12V vs 240V
Off-grid tiny homes often mix low-voltage 12V circuits (lights, fans) with 240V via an inverter for appliances. An electrician should design how the two systems interact.
Advantages
- 12V is efficient and safer at low voltage
- Runs from solar/battery
- Inverter covers mains appliances
Considerations
- More complex dual system
- Inverter and battery sizing matters
- Needs professional design
