What it costs in the GTA

JobTypical range
Full bathroom renovation, mid-range$15,000–$30,000
Powder room, full gut$8,000–$14,000
Cosmetic refresh (vanity, toilet, fixtures)$5,000–$10,000
Bathtub installation$2,500–$5,000

Before HST. Moving the toilet or shower, curbless showers and heated floors push the price up. Ranges where published GTA and Ontario sources overlap, checked November 2026. Not a quote.

Rebates, permits & rules

  • Moving or adding plumbing usually needs a building permit. Electrical work needs an ESA permit.
  • The exhaust fan should vent outside, not into the attic.
  • Condos: board approval, work-hour limits and elevator bookings add time and cost.
  • Signed the contract at your home? Ontario gives you 10 days to cancel most contracts signed there, for any reason.

What a complete quote includes

If any of these aren't on your quote, ask. Missing doesn't mean it's wrong, but it should be in writing.

  • Scope: cosmetic refresh or down to the studs
  • Waterproofing membrane behind and under the tile (brand named)
  • Tub or shower, and the valve
  • Tile type and area
  • Vanity, toilet, fixtures and faucets
  • Exhaust fan vented outside
  • Plumbing and electrical, with permits
  • Allowances for finishes, in dollars
  • Timeline, payment schedule tied to milestones, change-order process
  • Warranty
Watch out for
  • No waterproofing membrane listed in a tiled shower
  • Tiling over old tile or drywall in a wet area
  • Very low allowances
  • A full gut for under about $10,000 in Toronto: something's missing
Refresh or full gut?
  • Soft spots, loose tiles or mould around the tub mean water got behind the walls. That's a full gut.
  • Sound walls and floor? A new vanity, toilet, fixtures and paint can transform the room for much less.
  • Keeping the toilet and drain in the same spot saves a lot of money.
  • Budget a 10–15% contingency for what's behind the walls.

  5. Where does the exhaust fan vent?

Common questions

How much does a bathroom renovation cost in Toronto?

A full mid-range bathroom renovation typically runs about $15,000–$30,000 before HST.

Why does waterproofing matter in a bathroom quote?

Tile and grout aren't waterproof. A membrane behind the tile keeps water out of the walls. You can't check it once the tile is up, so get it in writing.

Can I renovate a bathroom for $10,000 in Toronto?

A cosmetic refresh, yes. A full gut of a main bathroom, rarely.
