Plumbing fixture upgrades are among the most impactful per-dollar bathroom improvements in Ontario homes. Here is a practical guide for 2026.
When a Permit Is Required
Permits required: new fixture additions, relocating fixtures, adding drain lines, replacing in-wall supply lines. Permits NOT required: like-for-like same-location replacements (swapping a toilet, faucet, or showerhead in the identical location).
Licensed Plumber Requirement
All permitted plumbing in Ontario requires a licensed plumber (Certificate of Qualification). Unlicensed plumbing voids home insurance and creates sale liability. Always verify COQ before hiring.
Labour Costs Ontario 2026
Toilet (same location): $150-$350. Faucet (same location): $100-$250. Showerhead: $75-$200. Shower valve: $300-$600. Tub (same location): $500-$1,200. Vanity with plumbing: $400-$900.
Water Efficiency Rebates
Toronto Water, York Region, and Peel Region offer rebates on WaterSense-certified toilets (1.28 GPF or less). Check your municipality’s program before purchasing to maximize rebate eligibility.
Older Home Plumbing Issues
Lead service lines (pre-1955): Toronto covers public portion, owner covers private side. Galvanized steel (1950s-1970s): rust reduces flow. Polybutylene (1970s-1990s): prone to cracking — replacement recommended before sale.
