What to look for when hiring bathroom renovations in Sarnia

  • Confirm the contractor coordinates all subtrades (plumbing, tiling, electrical), or clarify which trades you need to hire separately.
  • Ask about waterproofing methods around showers and tub surrounds — inadequate waterproofing is the leading cause of costly water damage in bathroom renovations.
  • Ensure all electrical work (including GFCI outlets near water) is ESA-permitted and inspected before walls are closed up.
  • Ask for a clear timeline — bathroom projects are disruptive and you need to know exactly how long you'll be without the space.

Frequently Asked Questions — Bathroom Renovations in Sarnia

How much does a bathroom renovation cost in Ontario?
A basic refresh (vanity, toilet, fixtures) runs $5,000–$12,000. A full ensuite renovation with custom tile, walk-in shower, and double vanity typically costs $20,000–$45,000. Plumbing relocations and layout changes add significantly to the total.
How long does a full bathroom renovation take?
A cosmetic update (new vanity, toilet, paint) takes about one week. A full gut-and-remodel with new tiling and plumbing typically takes 2–4 weeks. Custom tiles or specialty fixtures can extend the timeline if they need to be ordered.
Do bathroom renovations require permits in Ontario?
Plumbing and electrical work in bathrooms requires ESA and municipal permits. Moving fixtures (relocating a toilet or shower drain) always requires a plumbing permit. A qualified contractor will obtain all necessary permits before work begins.
What is the best flooring for a bathroom in an Ontario home?
Porcelain or ceramic tile is the most durable and water-resistant option and the most popular choice. Luxury vinyl plank (LVP) is a budget-friendly alternative with excellent water resistance. Avoid solid hardwood in bathrooms — it warps with the humidity fluctuations common in Ontario homes.
