What should I budget for adding a heated mirror pad behind my bathroom mirror in a Vancouver renovation?

A heated mirror pad (demister pad) is one of the most affordable upgrades in a bathroom renovation, typically costing $150–$400 installed in Metro Vancouver.

The pad itself — a thin electric heating element that adheres to the back of the mirror and prevents condensation from fogging the glass — runs $40–$120 for the pad depending on size. A 24x36 inch pad suitable for a standard vanity mirror costs roughly $60–$90 from local suppliers or online. Larger pads for double vanity mirrors or custom frameless mirrors run $90–$150.

The majority of the cost is electrical. In BC, a licensed electrician must connect the pad to a dedicated or shared circuit, and the work requires a permit if it involves adding a new circuit or modifying an existing one. Electrician labour in Metro Vancouver typically runs $100–$150 per hour, and connecting a demister pad is usually a 1–2 hour job if the work is done during a broader renovation when walls are open. If walls are already finished and the electrician needs to fish wire, expect the labour cost to climb to $250–$400 or more.

The most cost-effective approach is to include the demister pad in a full bathroom renovation while walls are open and the electrician is already on site for other work (fan wiring, lighting, heated floor thermostat). Adding it as a standalone project after renovation is complete means paying for an electrician to fish wire through finished walls, which significantly increases cost and disruption.

From a BC code standpoint, all bathroom electrical work must be done by a licensed electrician with Technical Safety BC oversight. Demister pads draw relatively low wattage (typically 60–150 watts depending on size) and can often share a circuit with bathroom lighting, but your electrician will confirm the appropriate circuit configuration based on your bathroom's existing electrical load. GFCI protection is required for all bathroom circuits.

One Metro Vancouver-specific consideration: given the region's persistent humidity and the fact that bathroom mirrors fog heavily in Vancouver's climate, a demister pad is genuinely useful here — more so than in drier climates. Pair it with a properly rated exhaust fan (minimum 50 CFM, ideally 80 CFM or higher) ducted to the exterior, and your mirror will stay clear while moisture is actively removed from the bathroom rather than just kept off the glass surface.

Practical tips: Choose a pad sized to cover at least 70–80% of your mirror's surface area for effective fog prevention. Pads with a built-in thermostat maintain a consistent surface temperature without overheating. If you're installing a new mirror as part of the renovation, have the electrician rough in a switched outlet or hardwired connection behind the mirror location before the mirror goes up — it's a 15-minute task during rough-in that saves significant cost later.

This is not a DIY electrical project — hardwiring any fixture in a BC bathroom requires a licensed electrician and the appropriate permit. But at $150–$400 all-in during a renovation, it's one of the better value-for-money comfort upgrades available.
