A bathroom renovation in Toronto costs $8,500 to $70,000 CAD, takes 3 to 8 weeks, and requires licensed trades, proper permits, and professional waterproofing to protect your home long-term.
Bathroom renovation is one of the highest-return projects a GTA homeowner can make, returning 75 to 85% of cost at resale. But that return only holds when the work is done right. Licensed trades, proper waterproofing, and pulled permits are what separate a project that adds value from one that creates problems at the worst possible time.
Read on to get the complete bathroom renovation checklist that walks you through every cost, every decision, and every step before a single tile comes off the wall.

What Does a Full Bathroom Renovation Include?
Step 1: Set Your Budget and Understand the Costs
First, set a realistic budget based on your bathroom size, home age, and renovation scope. GTA labour, permits, and older housing stock all affect costs differently from national averages.
Here is what Toronto homeowners actually pay in 2026:
| Scope | What’s Included | GTA Cost 2026 |
| Cosmetic Refresh | Vanity, fixtures, paint, no plumbing moves | $3,000 – $12,000 |
| Standard Full Reno | New tile, shower, vanity, all fixtures | $12,000 – $25,000 |
| Premium Renovation | Custom finishes, semi-custom cabinetry, layout changes | $25,000 – $40,000 |
| Luxury Gut Reno | Heated floors, stone tile, frameless glass, full ensuite | $40,000 – $70,000+ |
| Condo Bathroom Reno | Standard reno plus board approval, elevator, restricted hours | Add 10–20% |
| Contingency Buffer | Mould, rotten subfloor, asbestos in pre-1980 homes | Add 10–15% |
| Labour (all tiers) | Licensed plumber and electrician at $100–$150/hr | 40–60% of budget |
Mid-range bathroom renovations in Toronto return 75–85% of the cost at resale. That figure comes directly from the Appraisal Institute of Canada. It makes bathroom renovation one of the strongest home improvement investments across the GTA.

Step 2: Plan Your Layout, Design, and Material Choices
Plan your layout before selecting any material. Keeping your toilet, shower, and vanity in the same location saves $2,000 to $5,000 in plumbing costs. That saved money buys significantly better materials than a layout change ever will.
Here is what GTA homeowners actually spend on materials in 2026:
| Material | Budget Option | Premium Option |
| Floor Tile (installed) | Ceramic $8–$15/sq ft | Large format porcelain $10–$20/sq ft |
| Wall Tile (installed) | Ceramic $8–$12/sq ft | Natural stone $20–$40/sq ft |
| Vanity (installed) | Stock unit $800–$1,500 | Semi-custom $2,500–$8,000 |
| Shower Enclosure | Budget glass door $650 | Custom frameless glass $1,800–$3,500 |
| Heated Floor System | Basic mat $800–$1,500 | Premium system $1,500–$2,500 |
| Tub to Shower Conversion | Acrylic base $9,000–$10,000 | Full tiled curbless $10,000–$15,000 |
Tile, vanity, and shower enclosure are the three surfaces you see and touch every single day. So allocate your budget here first. Once your selections are confirmed, order everything before the demo begins.
Specialty porcelain and natural stone take 4 to 8 weeks to arrive at GTA suppliers. For tile and flooring installation across the GTA, professional flooring and tiling services cover every material from ceramic to natural stone.
Step 3: Check If You Need a Permit in Toronto or the GTA
Permit requirements in Toronto depend entirely on the scope of your bathroom renovation. Here is exactly what does and does not require one:
| Work Type | Permit Required? |
| Moving or adding plumbing | Yes |
| Any new electrical circuits | Yes |
| Structural changes, removing walls | Yes |
| Condo bathroom renovation | Yes, plus condo board approval |
| Retiling in same location | No |
| Vanity swap, no plumbing moves | No |
| Painting and cosmetic updates | No |
The City of Toronto Building Permit fee runs $11.53 per square metre, with a minimum of $214.79 in 2026. On top of that, all electrical work needs ESA Ontario certification. Skipping either risks stop-work orders and insurance complications at the worst possible time.
Condo owners also need board approval, adding 2 to 6 weeks before work begins. A good contractor handles all of this for you. Homeowners combining their bathroom with a whole home renovation need permit coordination across every scope from day one.

Step 4: Hire the Right Bathroom Renovation Contractor
Choosing the wrong contractor can quickly double your budget and delay your project.
Before you sign anything, verify their WSIB coverage at wsib.ca. If they don’t have it, you could be personally liable for any on-site injuries under Ontario law.
Always get at least three written, itemized quotes after contractors visit your site. This helps you understand the real market rate and spot bids that are too high or suspiciously low.
Check verified reviews on HomeStars. It’s one of Ontario’s most trusted platforms, and repeated feedback shows how contractors deal with delays and issues.
Avoid paying more than 40% upfront. Make sure everything is clearly written in a contract before work begins.
A professional bathroom renovation service in Toronto should include licensed trades, WSIB coverage, permit handling, and a written warranty.
Step 5: Prepare Your Home Before Demo Day
Good preparation before demo day keeps your project on schedule and protects the rest of your home from unnecessary damage.
- Clear the bathroom completely. Every product, towel, and personal item needs to go.
- Locate your main water shut-off valve. In older Etobicoke and Scarborough bungalows, it sits near the front basement wall.
- Protect hallway floors leading to the bathroom. Tile cuts and debris travel further than expected.
- Confirm all materials are ordered and on-site or confirmed in transit. Starting a demo without confirmed stock extends your timeline significantly.
- Plan your temporary bathroom arrangement before demo begins. Single-bathroom households need this sorted in advance.
- For condo owners in Toronto, book the elevator and confirm approved work hours with building management before day one.
Homeowners tackling a bathroom renovation as part of a larger project can explore living and bedroom renovation services to coordinate multiple scopes under one contractor.
Step 6: Complete the Demolition and Rough-In Work
Demolition takes the space down to the studs and subfloor. In many pre-1980 GTA homes, this is when issues show up—hidden mould, a rotten subfloor, or old galvanized pipes. A good contractor will document everything and get your written approval before moving forward.
Once the subfloor passes inspection, licensed plumbers handle the rough-in. If you keep fixtures in the same place, expect to spend around $1,200 to $1,800 per fixture. Moving a drain can add $2,000 to $3,500.
Next comes the electrical rough-in. After that, the City of Toronto carries out a mandatory inspection before any walls are closed.
If you’re also adding a basement bathroom, you can coordinate everything through professional basement renovation services. They’ll manage permits and inspections across the entire project.
Step 7: Waterproofing, Plumbing, and Electrical Work
This step often decides whether your bathroom lasts 5 years or 25.
In Toronto’s climate, freeze-thaw cycles and high summer humidity can quickly expose poor waterproofing. That’s why a proper waterproofing membrane system—like Schluter Kerdi—is used to create a continuous vapour-tight barrier across all wet areas.
All electrical work must include GFCI outlets on every circuit, and it must be inspected and certified by the Electrical Safety Authority (ESA) before walls are closed.
Ventilation is just as important. Your exhaust fan should be sized at a minimum of 1 CFM per square foot and always vented directly to the exterior.
If you’re upgrading with heated floors or smart ventilation systems, you can work with smart home renovation services that integrate everything under one licensed, coordinated team.

Step 8: Install Tiles, Fixtures, and Finishes
Large-format porcelain requires a perfectly flat base; any movement in the subfloor can cause cracks within a single Toronto winter. After tiling, the vanity is secured to the wall studs, followed by plumbing connections from a licensed plumber.
The toilet is installed last, once the tile is fully cured and the flange height is correctly set. Finally, moisture-resistant silicone seals all edges, since standard caulk breaks down quickly in local humidity
Step 9: Do a Final Walkthrough Before Signing Off
Never release the final payment before a full walkthrough. Test every fixture, flush toilets, run both hot and cold water, and check for any drainage issues. Press test buttons on all GFCI outlets. Inspect grout lines and all caulking for gaps or defects. Make sure the exhaust fan vents outside, not into the attic.
Collect all permit approvals and inspection records before the contractor leaves. These documents protect you under Ontario requirements. For larger upgrades beyond the bathroom, whole-home renovation services across the GTA can manage full-property coordination.
How Long Does a Bathroom Renovation Take in Toronto?
A standard bathroom renovation in Toronto takes 3 to 4 weeks for active construction. Full gut renovations with plumbing relocation run 6 to 8 weeks. Add 4 to 8 weeks for planning, materials, and permits before demo begins.
That total timeline surprises most GTA homeowners. Beyond active construction, the City of Toronto permit review, trade sequencing, and material lead times on custom vanities and imported tile add weeks before a single wall comes down.
For condo owners in Toronto, board approval and elevator coordination add another 2 to 6 weeks on top of that.

Common Bathroom Renovation Mistakes to Avoid in 2026
These are the mistakes GTA homeowners make repeatedly. Each one costs real money to fix after the fact.
- Contractors using generic board save money upfront. You pay when a shower leak destroys your subfloor and ceiling below within months.
- Custom vanities take 4 to 8 weeks to arrive. Starting demo before stock is confirmed leaves your bathroom gutted with no end date.
- If a worker gets injured in your home and your contractor has no WSIB coverage, Ontario law holds you personally liable.
- Unpermitted plumbing or electrical kills GTA home sales. Banks refuse mortgages on properties with missing or open permits.
- Relocating a single drain adds $2,000 to $3,500. Most GTA homeowners discover this mid-project when the budget is already committed.
- Toronto’s sealed winter homes trap daily moisture. A fan below 1 CFM per square foot causes mould on brand new surfaces within two winters.
- Always confirm stock availability before demo day. A single backordered tile stops your entire project for weeks.
