Frequently Asked Questions — Bathroom Renovations in Sarnia
How much does a bathroom renovation cost in Sarnia?
A cosmetic bathroom refresh (new vanity, toilet, fixtures, paint) in Lambton County typically costs $3,000–$8,000. A mid-range full renovation with new tile and shower runs $10,000–$20,000. A luxury primary bathroom renovation can exceed $30,000.
Do I need a permit for a bathroom renovation in Ontario?
Permits are required if you are moving plumbing or electrical circuits, or making structural changes. A cosmetic renovation (replacing fixtures, tile, vanity in the same location) typically does not require a permit. Your contractor can advise based on the specific scope.
How long does a bathroom renovation take?
A simple cosmetic update takes 3–7 days. A full gut-and-rebuild including new plumbing, electrical, tile, and fixtures typically takes 2–4 weeks. Always factor in lead times for materials — specialty tile and custom vanities can take 4–8 weeks to arrive.
What should I prioritise in a bathroom renovation?
Prioritise waterproofing and moisture protection above all else — bathroom water damage is expensive to fix. A quality shower pan, proper cement board behind tile, and ventilation fan are non-negotiable. Cosmetic choices matter far less than the waterproof substrate underneath.
