What Are the Rules for Bathroom Electrical Outlets Near Water in Alberta?

All electrical outlets in Alberta bathrooms must be protected by a Ground Fault Circuit Interrupter (GFCI), and the Alberta Building Code — which adopts the Canadian Electrical Code — requires specific placement rules for outlets, switches, and fixtures relative to water sources. These rules exist to prevent electrocution in the wet environment of a bathroom, and they apply to all new installations and renovations in Calgary and across the province.

The most important rule is GFCI protection. Every receptacle (outlet) in a bathroom must be on a GFCI-protected circuit, regardless of its distance from the sink, tub, or shower. A GFCI device detects tiny imbalances in electrical current — as small as 5 milliamps — and trips the circuit in a fraction of a second, preventing potentially fatal electrical shock. GFCI protection can be provided either by a GFCI-type receptacle (the outlet with the "Test" and "Reset" buttons) or by a GFCI circuit breaker in your electrical panel that protects the entire circuit. In Calgary bathroom renovations, most electricians install GFCI receptacles at the point of use for easy testing and resetting.

The Canadian Electrical Code, as adopted in Alberta, establishes zones around water sources where specific restrictions apply. Within the bathtub or shower area — defined as the space directly above the tub or shower pan extending to a height of 2.5 metres — no switches or receptacles are permitted. This zone is reserved for only permanently connected fixtures like shower lighting (which must be rated for wet locations) and exhaust fans. Outside the tub or shower enclosure but within approximately 1 metre of the edge of a sink basin, at least one GFCI-protected receptacle is required. This outlet serves daily grooming needs — hair dryers, electric razors, and similar appliances.

Bathroom lighting fixtures also have specific requirements based on their proximity to water. Fixtures installed directly in a shower or above a bathtub must carry a wet location rating (look for "Suitable for Wet Locations" on the fixture label). Fixtures near but not directly in the water zone require a damp location rating at minimum. Recessed pot lights installed in shower ceilings are a popular choice in Calgary bathroom renovations — ensure they are IC-rated (insulation contact), airtight, and wet-location rated.

For heated floor systems, which are an especially popular upgrade in Calgary bathrooms given the cold winters and frequently cold concrete basement slabs, the thermostat must be GFCI-protected and the heating cable or mat must be installed according to manufacturer specifications. The electrical circuit for radiant floor heating requires its own dedicated breaker, and the installation must be inspected by a Safety Codes Officer before tile is laid over the heating elements.

Exhaust fans require their own considerations. The fan should be on a dedicated circuit or shared only with bathroom lighting — never on the same circuit as GFCI-protected receptacles, as nuisance tripping can occur. The fan switch should be located inside the bathroom but outside the tub or shower zone. Humidity-sensing fan controls that activate automatically are ideal for Calgary's climate, where the extreme swing from very dry indoor air (often below 20% humidity in winter) to high shower humidity stresses materials and can promote mould if moisture is not exhausted promptly.

All bathroom electrical work in Calgary — adding outlets, moving switches, installing heated floors, upgrading lighting circuits, or adding exhaust fan circuits — requires an electrical permit and must be performed by a certified electrician. An electrician's hourly rate in Calgary typically runs $75 to $130 per hour, and the permit plus inspection adds approximately $75 to $150. Never attempt DIY electrical work in a bathroom — the combination of water and electricity is genuinely life-threatening, and unpermitted electrical work creates liability and insurance issues.
