A bathroom renovation covers everything from a quick refresh (new vanity, tile, and fixtures) to a full gut job that moves plumbing and touches the subfloor. In Toronto that usually means coordinating a licensed plumber for supply and drain lines, an electrician for GFCI outlets and exhaust fan venting, a tiler, and someone to handle waterproofing behind tubs and showers before anything gets covered up. We've listed 34 businesses in this category, ranging from small renovation crews to larger design-build firms, so the range of price, scheduling, and communication style varies a lot from one to the next.
What to look for before you sign a contract
- Permits and licensing: moving plumbing or electrical in Toronto requires a permit, and a contractor who shrugs that off is a red flag.
- Waterproofing method: ask what membrane or system they use in the shower and around the tub, since this is the single most common source of expensive water damage down the line.
- A written scope and timeline: vague quotes lead to vague results. A clear scope of work with allowances for tile and fixtures protects both sides.
- References or past project photos: especially for full gut renovations, since the plumbing and waterproofing work is hidden once the job is done.
How our scoring works
Each contractor on this list is scored using the same criteria across the category, based on factors like customer feedback, responsiveness, and consistency over time, not just star ratings. For the full breakdown of what we measure and how weightings are applied, see our methodology page. If you want the shortlist rather than the full directory, our ranked guide to the best renovation contractors in Toronto narrows things down further.
