How do I plan for enough electrical outlets and their placement during the design phase?

Planning electrical outlet placement during the design phase is critical because adding outlets after your bathroom tile and finishes are installed means cutting into finished walls, patching tile, and paying for a second round of electrical work — a mistake that costs GTA homeowners $500–$1,500 to fix after the fact. Getting this right during the rough-in stage costs almost nothing extra, so it’s one of the highest-value planning exercises in a bathroom renovation.

Ontario Code Requirements

The Ontario Electrical Safety Code (which follows the Canadian Electrical Code with Ontario amendments) has specific requirements for bathroom outlets. Every bathroom must have at least one GFCI-protected receptacle within 1 metre of each sink basin. GFCI (Ground Fault Circuit Interrupter) protection is non-negotiable in any wet environment — it detects current leakage and cuts power in milliseconds to prevent electrocution. All bathroom receptacles must be GFCI-protected, either through a GFCI-rated outlet or by being downstream of a GFCI breaker in your electrical panel.

All electrical work in Ontario bathrooms requires a permit and ESA (Electrical Safety Authority) inspection before being concealed behind walls. Your licensed electrician should pull the permit and arrange the inspection as part of their scope of work. Never allow electrical rough-in to be covered with drywall or tile before the ESA inspection — if the inspector needs to see the wiring after it’s concealed, you’re paying to open and refinish walls.

How Many Outlets and Where

For a standard three- or four-piece bathroom in a Toronto home, plan for a minimum of two to three GFCI outlets. Here’s a practical placement guide:

• Vanity area: One outlet on each side of the mirror, positioned 40–44 inches from the floor (just above countertop height) and at least 12 inches from the sink edge to keep cords away from water. For a double vanity, you want an outlet accessible from each sink station — that’s two outlets minimum. These handle hair dryers, electric razors, electric toothbrush chargers, and curling irons
• Toilet area: An outlet near the toilet at 16–18 inches from the floor is increasingly standard in GTA renovations. This powers a bidet seat (which requires a grounded outlet within cord reach of the toilet) and is also useful for a nightlight or small space heater. With electronic bidet seats growing rapidly in popularity across Toronto, this outlet is no longer a luxury — it’s practical planning
• Heated floor thermostat: If you’re installing electric radiant floor heating (one of the most requested upgrades in Toronto bathroom renovations, at $8–$15 per square foot for the mat and installation), you need a dedicated electrical box for the thermostat, typically placed 48–60 inches from the floor near the bathroom entrance, similar to a light switch location. The heated floor system also requires its own dedicated 15- or 20-amp circuit with GFCI protection
• Exhaust fan: While not an outlet per se, your exhaust fan needs its own switch and wiring. Many GTA homeowners upgrade to a fan/light/heater combination unit ($200–$600 for the unit), which requires appropriate wiring capacity. Plan the switch location during design — typically near the main bathroom light switch at the door entry, 48 inches from the floor

Planning Tips for GTA Homes and Condos

In Toronto condos, electrical capacity can be a limiting factor. Most condo units have a 100-amp main panel, and bathroom circuits share capacity with other areas of the unit. If you’re adding a heated floor, bidet seat outlet, and upgraded lighting, have your electrician verify that your panel has capacity for the additional circuits. Adding a sub-panel in a condo is possible but requires building management approval and costs $800–$1,500.

In older Toronto homes (pre-1970s), the bathroom may have only a single ungrounded outlet or even no outlets at all. Bringing the electrical up to current code during a renovation is strongly recommended — you’ll need new wiring run from the panel, proper grounding, and GFCI protection. Budget $500–$1,500 for bathroom electrical upgrades depending on the scope and distance from the panel.

Don’t forget to plan outlet placement around your tile layout. Outlets that land in the middle of a tile look sloppy. Work with your electrician and tile installer to position outlet boxes so they align with grout lines or tile edges. This coordination happens during the design phase and costs nothing extra but makes a visible difference in the finished result.

A licensed electrician in the GTA typically charges $75–$120 per hour, and adding an extra outlet during rough-in costs roughly $100–$200 per outlet (including the box, wire run, and device). Compare that to the $500–$1,500 cost of adding an outlet after the renovation is complete, and the value of thorough upfront planning is obvious.
