What are the NB building code requirements for a dedicated GFCI circuit in a basement bathroom and how close to the vanity must the outlet be?
In New Brunswick, basement bathroom outlets must be GFCI-protected and located within 1 meter (3 feet) of the vanity sink, but cannot be installed directly above the vanity countertop. The outlet should be on a dedicated 20-amp circuit separate from lighting and other bathroom loads.
The NB Electrical Code (based on the Canadian Electrical Code) requires GFCI protection for all outlets in bathrooms, regardless of location. For basement bathrooms specifically, this is even more critical due to the higher moisture levels typical in below-grade spaces. The outlet must be positioned where it's easily accessible for daily use (hair dryers, electric razors, etc.) but away from direct water exposure.
Proper placement means installing the outlet on the wall beside the vanity, typically 12-18 inches above the countertop level. You cannot install it directly above the vanity where water splashing is likely, and it cannot be more than 1 meter away from the sink edge. Many contractors install it on the side wall adjacent to the vanity or on the vanity wall itself, positioned to the left or right of the mirror.
The dedicated 20-amp circuit requirement exists because bathroom outlets often power high-draw appliances like hair dryers (1500+ watts). This circuit cannot serve other areas - it's exclusively for the bathroom outlets. However, the bathroom lighting can be on a separate 15-amp circuit shared with other lighting loads.
In NB's humid basement environment, proper GFCI installation is crucial. The GFCI breaker or outlet will trip more frequently in damp conditions, which is actually protecting you from shock hazards. Some contractors recommend installing the GFCI breaker at the panel rather than using a GFCI outlet, as panel-mounted units are less prone to nuisance tripping from basement humidity.
Installation timing matters for basement bathrooms. The electrical rough-in happens after framing and before insulation, requiring an electrical permit and inspection. The GFCI circuit must be tested during the rough-in inspection - inspectors will verify proper wiring, grounding, and GFCI function before allowing you to close up the walls.
Professional installation is required for this work in New Brunswick. Any new electrical circuits require a permit, and bathroom electrical work has specific safety requirements that must be inspected. A licensed electrician will ensure proper wire sizing (12 AWG for 20-amp), correct GFCI wiring, proper grounding, and code-compliant outlet placement.
The total cost for a dedicated GFCI bathroom circuit typically runs $300-$600 including permit, depending on the distance from your electrical panel to the bathroom location. If your main panel is an older 60-amp service (common in older NB homes), you may need a panel upgrade to accommodate the additional circuit load.
