Bathroom Electrical Safety Is Critical
Water and electricity don’t mix. Bathrooms present unique electrical challenges that building codes address with specific requirements. Understanding these rules helps ensure your bathroom is both functional and safe.
GFCI Protection Is Non-Negotiable
All bathroom outlets must have GFCI protection. This applies to existing homes when outlets are replaced and to all new construction. GFCIs prevent electrocution when wet hands contact faulty appliances.
Clearance Requirements
Outlets can’t be installed within 3 feet of bathtubs and showers. Light fixtures above showers need wet-location ratings and must maintain specific clearances. Exhaust fans have their own installation requirements.
Circuit Loading Considerations
High-wattage devices like hair dryers and curling irons stress bathroom circuits. Code requires at least one 20-amp circuit serving bathroom outlets. Many homes benefit from multiple bathroom circuits.
Ventilation Fan Wiring
Exhaust fans remove moisture that damages homes. Timer switches run fans long enough to clear humidity. Fan/light combinations need proper wiring for independent control. Quality fans with quiet motors make a noticeable difference.
