Toronto Bathroom Renovation Planning Checklist

Decide what stays and what moves

Mark the existing and proposed toilet, vanity, tub or shower, door and storage. Moving plumbing fixtures can change the permit, trade and preparation scope; keeping the layout may simplify coordination but still needs site verification.

Check permit requirements by scope

Toronto lists repairing and replacing plumbing fixtures among examples that may not require a building permit, while installing or modifying plumbing systems and making structural or material alterations commonly do. Use the City's official guidance and confirm the full scope rather than assuming all bathroom remodels are treated alike.

Record electrical and lighting changes

List new lighting, receptacles, switches, heated floors, fans and any panel work. ESA says hired home electrical work must be performed through a Licensed Electrical Contractor. Confirm the licence, notification and completion documentation.

Plan ventilation and service access

Document the existing fan and vent path, then confirm any proposed ventilation change. Keep access to plumbing shutoffs and serviceable components. Ventilation, electrical and ceiling work should be coordinated before finishes are installed.

Define the waterproofing and shower assembly

The visible tile is only one part of a shower. Define the substrate, waterproofing approach, drain, curb or entry, niche, glass and transitions as one assembly. Existing leaks or damaged materials should be investigated before the new finish is specified.

Coordinate tile, vanity and clearances

Confirm tile size and layout, vanity dimensions, door swings, fixture locations, mirror, lighting and storage together. Use actual product specifications so plumbing and electrical rough-ins match the selected fixtures.

Use real project photos to set expectations

Reference photos should identify specific details such as tile direction, grout contrast, glass, niche, vanity and lighting. Compare those details with the existing room dimensions rather than treating an inspiration photo as a complete scope.

Prepare a complete estimate package

Send wide and close-up photos, approximate dimensions, the proposed layout and selected products. Ask the estimate to identify demolition, disposal, repairs, waterproofing, tile, fixtures, regulated trades, permits, inspections, painting and cleanup.

Verify current requirements

Rules and guidance can change. These primary sources were reviewed on 2026-08-11; use them to confirm the requirements that apply to the property and scope:
