Does a cosmetic bathroom update — new tile, vanity, paint — require any permits?

A purely cosmetic bathroom update — replacing tile, swapping the vanity, and painting — generally does not require building, plumbing, or electrical permits in Toronto, as long as you are not modifying any plumbing connections, electrical wiring, or structural elements. This is good news for GTA homeowners looking to refresh a dated bathroom without the added time and cost of the permit process.

The key word here is cosmetic. You are updating finishes and fixtures in their existing locations without changing the underlying systems. Specifically, you can do the following without permits: remove old floor and wall tile and install new tile in the same areas, replace the vanity cabinet and countertop with the sink drain connecting at the same location, swap the faucet on the existing supply lines, repaint walls and ceiling with mould-resistant semi-gloss paint, replace the mirror or medicine cabinet, install new bathroom hardware (towel bars, toilet paper holder, robe hooks), replace the toilet with a new one using the same rough-in measurement, and re-caulk around the tub and shower.

These are all straightforward replacements where the new components connect to the same plumbing and electrical points as the old ones. No new connections, no relocated drains, no modified wiring.

Where Cosmetic Becomes Permitted Work

The line between cosmetic and permitted work can blur quickly, and this is where Toronto homeowners need to pay attention. Here are common scenarios where a seemingly cosmetic update actually requires permits:

Adding a GFCI outlet where one does not currently exist requires an electrical permit and ESA inspection. If your older Toronto home has a bathroom with no GFCI protection — common in pre-1980s homes across Scarborough, Etobicoke, and North York — adding one is a smart safety upgrade, but it does require a permit. However, simply replacing an existing standard outlet with a GFCI outlet on the same circuit is typically considered maintenance and does not require a permit.

Installing a heated floor under new tile requires an electrical permit because you are adding a new dedicated circuit. This is one of the most popular upgrades in GTA bathroom renovations given Toronto's long winters, but it moves your project from cosmetic to permitted.

Replacing a tub with a walk-in shower involves modifying the drain location and subfloor — this requires a plumbing permit even though it might feel like a cosmetic change. The drain needs to be relocated, the subfloor may need modification for proper slope, and the waterproofing system changes entirely.

Upgrading the exhaust fan from a basic model to a higher-CFM unit is generally fine if you are using the existing wiring and vent duct. But if the upgrade requires a new circuit or new ductwork to the exterior, permits apply.

Budget for a Cosmetic Update in the GTA

A cosmetic bathroom refresh in the Greater Toronto Area typically costs $8,000–$18,000 depending on the size of the bathroom and the quality of materials you choose. This includes demolition of old tile ($500–$1,500), new tile supply and installation ($2,000–$6,000), a stock or semi-custom vanity with countertop ($500–$2,500), a new toilet ($300–$600 installed), paint ($200–$500), and new hardware and accessories ($200–$600). Without the need for permits or licensed plumbing and electrical trades, you save both time and money compared to a full renovation — though hiring a skilled tile installer is still strongly recommended for professional results that last.
