Can I put a regular light switch inside the bathroom, or does it need to be a certain distance from the shower?

Yes, you can put a regular light switch inside a bathroom in Ontario, but it must be located outside the shower and bathtub zones as defined by the Ontario Electrical Safety Code. There is no blanket prohibition on switches inside bathrooms — the rules are about proximity to water sources, not about whether the switch is in the bathroom at all.

The key rule under the Canadian Electrical Code (which Ontario adopts) is that switches must not be installed within reach of a person standing in a bathtub or shower. Practically, this means the switch must be located so that someone standing in the tub or shower cannot reach it. The general guideline is a minimum of 1 metre (approximately 39 inches) from the edge of the bathtub or shower enclosure. Most GTA bathroom layouts naturally satisfy this requirement — the light switch is typically installed on the wall beside the bathroom door, which is well away from the tub/shower area.

Common GTA Bathroom Layouts

In the standard 5x8-foot bathroom found in thousands of post-war Toronto homes across Scarborough, North York, Etobicoke, and the inner suburbs, the light switch is almost always located on the wall immediately inside or outside the bathroom door. This position is typically 4–6 feet from the tub/shower, well within code compliance. The switch controls the vanity light, overhead light, and/or exhaust fan — sometimes with a single toggle, sometimes with a multi-gang switch plate (two or three switches side by side for separate control of lights, fan, and heated floor).

In GTA condo bathrooms, space is often tighter, and the switch location is constrained by the unit layout. Most condo builders install the bathroom switch just outside the bathroom door in the hallway. During a condo bathroom renovation, you can relocate the switch inside the bathroom as long as it maintains proper distance from the shower/tub. Your electrician will confirm the appropriate placement based on your specific layout.

For larger ensuites and master bathrooms common in newer Vaughan, Markham, Richmond Hill, and Brampton homes, you may have switches in multiple locations — one by the door for general lighting and fan, another near the vanity for vanity-specific lighting, and possibly a third for a water closet (toilet compartment) light. All of these are perfectly acceptable as long as none are within reach of the shower or tub.

Special Switch Types

Several switch upgrades are worth considering during a GTA bathroom renovation. Dimmer switches for vanity and overhead lighting let you adjust brightness — useful for nighttime bathroom visits without blinding yourself. Timer switches for exhaust fans are excellent — they let you set the fan to run for 20–60 minutes after you leave the bathroom, clearing all the moisture without leaving the fan running indefinitely. Humidity-sensing switches automatically activate the exhaust fan when bathroom humidity rises above a set threshold — particularly valuable in Toronto's humid summer months when bathroom moisture problems are most acute.

All switch installations and relocations require a licensed electrician, electrical permit, and ESA inspection in Ontario. The cost to install or relocate a bathroom switch is typically $100–$250 per switch location, including the device, wiring, and connection. A multi-gang switch plate (controlling lights, fan, and heated floor separately) is a worthwhile investment at $200–$400 installed for the convenience and control it provides.
