What a bathroom renovation really costs in Ontario (2026)

Ask three contractors what a bathroom renovation costs and you’ll get three very different numbers — because “a bathroom” can mean a refreshed powder room or a fully re-plumbed ensuite with heated floors. Here’s how the ranges actually break down for Ontario homes in 2026, and what moves the number.

The honest range

For a standard full bathroom (tub or shower, vanity, toilet, tile, lighting) with mid-range finishes, most Ontario homeowners should plan for a range like this:

Powder room

$4,000 – $9,000

Standard bath

$15,000 – $28,000

Primary ensuite

$28,000 – $55,000+

These are planning bands, not quotes. A verified pro confirms the real price after seeing the space — because the biggest swings hide behind the walls.

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.

What drives the price up

• Relocating plumbing or electrical rather than reusing existing rough-ins.
• Concealed conditions — old subfloor, hidden water damage, non-standard framing.
• Permit-triggering work (structural, electrical, additions).
• Occupied-home logistics: protecting the rest of the house adds time.

Plan before you quote

The homeowners who stay on budget are the ones who walk in already knowing their scope, their range, and their must-asks. That’s exactly what the HomeCopilot planner gives you in about two minutes — describe your bathroom (or upload a photo) and get a scope, a realistic range, and a prep checklist before anyone quotes you.
