What inflates bathroom renovation costs in Toronto
Mold behind tile. The most common hidden cost — discovered only on demo day. Full remediation: $1,500–4,000. Moving plumbing. Relocating the toilet or tub rough-in by even 12 inches can add $2,000–4,000. Floor sistering. Wet bathrooms often have compromised subfloor — sistering joists adds $800–2,000. Knob and tube. Any electrical work in homes built before 1985 may require replacing old wiring, adding $2,000–5,000.
Do you need a permit for a bathroom renovation?
Cosmetic work (tile, vanity, fixtures) does not require a permit in Toronto. Adding a new bathroom, moving the plumbing rough-in, or adding a bathroom where none existed — these all require plumbing permits. CNB pulls permits as required on every project.
Timeline: what to expect
A standard 3-piece gut and rebuild with no structural changes: 2–3 weeks once materials are on site. A full spa ensuite with custom tile and special-order fixtures: 4–6 weeks. Material lead times can add 2–4 weeks for custom orders — we discuss this before signing.
