Bathroom Renovation in Greater Toronto Area
Bathroom renovation covers everything from swapping a vanity and re-tiling a tub surround to a full gut job that moves plumbing, resizes the shower, and reworks the layout for better flow. In the GTA, most jobs fall into three tiers: a cosmetic refresh (new fixtures, tile, paint, vanity), a mid-range remodel (new tub-to-shower conversion, in-floor heating, updated plumbing and electrical to code), and a full renovation that touches the subfloor, waterproofing membrane, and sometimes wall layout. We list 46 bathroom renovation businesses serving the region, ranging from small owner-operator crews to larger design-build firms.
Before hiring, ask to see a detailed written quote that separates materials, labour, and permit costs, and confirm the contractor pulls the required building and plumbing permits for anything beyond a like-for-like fixture swap. Ask how they handle waterproofing behind tile (membrane brand, method) since this is the single biggest source of callback problems in wet rooms. Check WSIB coverage and liability insurance, ask for two or three recent local references with addresses you can look up, and get a realistic timeline in writing, since a mid-size bathroom typically takes two to four weeks once demolition starts.
Our scoring weighs verified reviews, response consistency, years active, licensing and insurance signals, and complaint patterns, so you're not relying on a single star rating.

Common questions about bathroom renovation
- How much does a bathroom renovation cost in the GTA?
- A basic refresh (new fixtures, vanity, tile, paint) usually runs $8,000 to $15,000. A mid-range remodel with a new shower or tub, updated plumbing, and better tile work lands in the $15,000 to $30,000 range. A full gut renovation with layout changes, in-floor heating, and custom work can push past $35,000, especially for ensuites or larger spaces. Get at least three quotes since pricing varies a lot by contractor overhead and finish level.
- How often does a bathroom need to be renovated?
- Most bathrooms hold up well for 15 to 25 years before a full renovation makes sense, though grout, caulking, and fixtures often need attention sooner. Signs it's time include failing grout or tile, water damage behind walls, an outdated layout that wastes space, or plumbing that's constantly needing repair.
- What should I expect during the renovation process?
- Expect demolition and disposal first, then rough-in plumbing and electrical work (with inspection if permits are pulled), waterproofing and tile, then fixtures, vanity, and finishing trim. You'll be without full use of that bathroom for most of the project, so plan around that if it's your only one. A reputable contractor will walk you through each stage and flag any surprises found once walls or flooring are opened up.
- How do I judge the quality of a bathroom renovation contractor?
- Look past the sales pitch to the details: do they explain their waterproofing method without being asked, do they pull permits for plumbing and electrical changes, and do their references check out when you actually call them. Consistent, specific reviews about communication and follow-through matter more than a high star average with few reviews behind it.
