What are the BC code requirements for bathroom lighting near a shower or bathtub?

All bathroom lighting installed within the shower or tub zone must be rated for wet or damp locations and protected by a GFCI (Ground Fault Circuit Interrupter) circuit — this is a firm BC Building Code and Canadian Electrical Code requirement, not a suggestion. Getting this wrong creates a serious electrocution risk in one of the most moisture-heavy rooms in your home, especially in Metro Vancouver where ambient humidity runs 75–85% year-round.

The Canadian Electrical Code (adopted by BC through Technical Safety BC) divides the area around showers and bathtubs into specific zones that determine what type of lighting fixture is permitted. Zone 0 is inside the tub or shower basin itself — only low-voltage (12V) fixtures with an IPX7 rating are allowed here, though most residential bathrooms avoid placing lights in this zone entirely. Zone 1 extends from the top of the tub or shower base up to 2.25 metres above the floor and includes the space directly above the tub or shower. Fixtures in Zone 1 must carry a "wet location" rating (sometimes marked "suitable for wet locations" on the fixture label) and be connected to a GFCI-protected circuit. Zone 2 extends 60 centimetres (roughly 2 feet) horizontally beyond the edge of the tub or shower and up to 2.25 metres above the floor. Fixtures here must be rated for at least "damp location" use, though wet-rated fixtures are always the safer choice in Vancouver's humid climate.

Recessed pot lights are the most popular choice for shower and tub areas in Metro Vancouver bathroom renovations. A recessed pot light rated for wet locations and IC-rated (insulation contact) for ceiling cavities typically costs $75–$200 per fixture installed, with most bathrooms needing two to four fixtures over the shower and tub area. Expect to pay $300–$800 total for shower-area lighting, including the GFCI circuit, depending on whether new wiring is required or you are tapping into an existing bathroom circuit.

Every bathroom receptacle and all circuits serving the tub and shower zones must have GFCI protection. In practice, this means either a GFCI breaker at the panel or GFCI receptacles on the circuit. Your electrician will determine the most practical approach based on your panel and existing wiring. GFCI protection trips the circuit in milliseconds if it detects current leaking to ground — such as through water or a wet hand touching a fixture — preventing electrocution.

Vancouver's persistent moisture makes fixture ratings even more important than in drier climates. A damp-rated fixture installed in a shower zone may pass initial inspection but corrode internally within a few years, creating both a safety hazard and an expensive replacement job that requires opening up the ceiling. Always choose wet-rated fixtures for any location within or directly above a shower or tub, even if code technically allows damp-rated in Zone 2.

All bathroom electrical work in BC must be performed by a licensed electrician and requires an electrical permit with inspection through Technical Safety BC. This is not a DIY project. The permit fee is typically $100–$200 for bathroom lighting work, and the inspection ensures your fixtures are properly rated, correctly installed, and GFCI-protected. Skipping the permit saves a small amount of money but creates a safety risk and a disclosure issue at resale — home inspectors routinely flag unpermitted electrical work in bathrooms.
