Bathroom Renovation Guide for Toronto Homeowners — 2026

Cost Ranges by Complexity

Powder rooms (half-baths) are typically at the lower end. Ensuites and main bathrooms with shower-to-tub conversions or layout changes trend higher. For detailed cost breakdowns across all project types, see our 2026 Cost Guide.

Timelines by Project Type

The scope of mechanical work — not the size of the room — is what drives your timeline.

Cosmetic Refresh (2–3 weeks)

Existing plumbing and electrical stay in place. Surface elements (tile, vanity, fixtures, lighting) are replaced. No permits typically required. This is the fastest and least disruptive option.

Full Renovation (4–6 weeks)

Complete demolition to wall studs. Waterproofing membranes replaced, in-wall plumbing and electrical updated, new fixtures installed. Even if fixtures go back in the same locations, exposing and replacing the mechanical systems triggers code compliance and adds time.

Layout Reconfiguration (6–10 weeks)

Moving a toilet flange or shifting a shower drain requires cutting into subfloor framing and altering the soil stack. This triggers structural assessments, comprehensive permitting, and multiple sequential inspections. It is the most complex and expensive scenario.

When You Need a Permit

The deciding factor is whether you are altering plumbing, electrical, or structural elements — not whether the room looks different when you are done.

Permits typically required for: moving or replacing plumbing supply or drain lines, modifying electrical circuits (including adding in-floor heating or new exhaust ventilation), removing or altering walls, and changing the room layout.

Permits typically NOT required for: painting, replacing fixtures in the same location without altering plumbing, swapping a vanity, or non-structural flooring replacement.

Any alteration to pressurized plumbing or drainage requires a specific plumbing permit from the City of Toronto. Electrical modifications must be performed by a Licensed Electrical Contractor (LEC) and inspected by the Electrical Safety Authority (ESA). Submit permit applications through Toronto Building using the updated form (effective February 16, 2026). Learn more about the full permit process.

Condo Bathroom Renovations

Condo projects add another layer of complexity. Beyond city permits, you need formal approval from your condo board — which dictates working hours, elevator booking for material delivery, and coordination for shutting down shared water risers. Your contractor must carry WSIB certification and comprehensive liability insurance ($2M+) to meet most boards' requirements. Plan for 4–10 weeks of board approval time before construction can begin.

Waterproofing — The Non-Negotiable

In older Toronto homes, the most critical (and invisible) element of a bathroom renovation is the waterproofing system behind the tiles. Outdated cement board and failed membranes are the leading cause of long-term moisture damage, mould, and structural decay. A full renovation should always include modern integrated membrane systems installed to current code standards. This is not a place to cut costs.

Next Steps

Start with a clear understanding of which tier your project falls into — cosmetic, full, or reconfiguration. That single decision determines your budget range, timeline, and permit requirements.

Explore available tax credits and rebates that may apply to your project, especially if you are adding accessibility features or energy-efficient upgrades.
