Bathroom Renovation Cost in Ontario (2026)
Most Ontario bathroom renovations land between $12,000 and $30,000 in 2026. Powder rooms sit lower; primary ensuites with moved plumbing sit higher. These are planning ranges, not quotes.
HomeCopilot Editorial
Ask three contractors what a bathroom renovation costs and you'll get three different numbers, because "a bathroom" can mean a refreshed powder room or a fully re-plumbed ensuite. Here's how the ranges break down for Ontario homes in 2026, and what moves the number.

Where the money actually goes
- Labour — usually the largest single line, and the one that varies most by scope and city.
- Plumbing changes — moving a toilet or shower drain is where budgets quietly balloon.
- Tile and waterproofing — large-format tile and proper waterproofing cost more up front and fail less.
- Fixtures and finishes — the easiest place to spend (or save) without changing the scope.
FAQ
Does a bathroom renovation need a permit in Ontario?
Like-for-like fixture swaps usually don't. Moving plumbing, electrical changes, or structural work often do. Your contractor confirms and pulls the permit where it's required.
What's the single biggest cost driver?
Relocating plumbing. Keeping the toilet, sink, and shower drains where they are keeps far more of your budget in finishes.
