Whether you're updating a dated main bath in Birchcliff or gutting a basement washroom in Malvern, understanding bathroom renovation costs in Scarborough helps you budget realistically and avoid unpleasant surprises. Labour rates, material choices, and the age of your home all influence the final number — and in 2026, GTA pricing continues to reflect strong demand for skilled trades. This guide walks you through what to expect, what drives costs up or down, and how to protect yourself when hiring a bathroom contractor in Scarborough.
Typical Bathroom Renovation Cost Ranges in Scarborough (2026)
Bathroom reno prices in Scarborough vary widely depending on the scope of work, the size of the room, and the quality of fixtures and finishes. Here are realistic ranges for the most common project types, including materials and labour, before HST:
- Basic refresh (cosmetic update): $8,000 – $15,000. New vanity, toilet, faucets, lighting, paint, and possibly new flooring — without moving any plumbing or walls.
- Mid-range renovation: $15,000 – $30,000. Full gut and replacement of fixtures, new tile work, updated plumbing rough-in, exhaust fan, and potentially a new tub-to-shower conversion.
- Full custom renovation: $30,000 – $60,000+. High-end tile, walk-in shower with glass enclosure, heated floors, custom cabinetry, full plumbing and electrical updates, and premium fixtures throughout.
Add 13% HST to all quoted amounts. On a $25,000 project, that's an additional $3,250 — a line item that surprises some homeowners when they first see it on a contract.
What Affects the Price of a Bathroom Renovation in Scarborough
1. Home Age and Hidden Conditions
Scarborough has a large stock of post-war bungalows, 1960s–1980s semis, and older detached homes. Once walls open up, contractors frequently find galvanised steel pipes, knob-and-tube wiring, asbestos-containing drywall compound, or substandard venting. Remediation adds cost — budget a contingency of 10–15% for homes built before 1990.
2. Plumbing Changes
Keeping fixtures in their current locations keeps costs down. Moving a toilet, repositioning a shower drain, or adding a double sink where a single existed requires a licenced plumber and likely a permit. Plumbing rough-in work alone can add $2,000 – $8,000 depending on complexity.
3. Electrical Work
Ontario's Electrical Safety Authority (ESA) requires all electrical work in a bathroom to meet current code — including GFCI-protected outlets, proper lighting circuits, and exhaust fan wiring. Any homeowner who allows unlicenced electrical work risks failed inspections and voided home insurance. Ensure your contractor uses an ESA-licenced electrician for this portion of the work.
4. Tile and Finishes
Tile is one of the biggest cost levers in any bathroom reno. Builder-grade ceramic can cost $3–$6 per square foot, while large-format porcelain or natural stone runs $15–$40+. Labour for intricate patterns or heated-floor installation adds further to the total.
5. Shower and Tub Selection
A standard acrylic tub-and-surround costs considerably less than a custom-tiled walk-in shower with a frameless glass enclosure. The latter can account for $8,000 – $20,000 of a project budget on its own.
6. Contractor Type and Experience
A general contractor who coordinates plumbers, electricians, and tile setters charges a management premium — typically 15–20% above subcontractor costs — but also takes responsibility for scheduling, quality control, and the overall permit process. Hiring trades independently may appear cheaper but adds coordination risk and liability to the homeowner.
Permit Requirements for Bathroom Renovations in Scarborough
Scarborough falls under the City of Toronto for building permits. A permit is generally required when work involves structural changes, new plumbing rough-ins, or significant electrical upgrades. Cosmetic refreshes (new vanity, paint, fixtures) typically do not require a permit, but any drain relocation or wall removal usually does.
Your contractor should pull the permit — not you. A licenced general contractor in Ontario is registered with Ontario College of Trades (OCOT) and understands the local inspection process. Trades working on your project should carry WSIB coverage and adequate liability insurance. Always ask for proof of both before work begins.
Gas-related work — such as a gas fireplace near an ensuite or a boiler serving radiant-floor heat — falls under TSSA (Technical Standards and Safety Authority) jurisdiction and must be performed by a licenced gas fitter.
Practical Tips Before Hiring a Bathroom Contractor in Scarborough
- Get at least two to three written quotes. Compare scope, not just price. A lower quote that excludes permit fees or subcontractor markups can end up costing more.
- Verify credentials. Confirm WSIB clearance, ESA licencing for electrical subcontractors, and general liability insurance before signing anything.
- Understand the payment schedule. A reasonable deposit is 10–20%. Be cautious of contractors requesting more than one-third of the total upfront.
- Plan for your bathroom to be out of service. A full renovation in a single-bathroom home typically takes two to four weeks. Discuss a realistic timeline before work starts.
- Clarify what is and isn't included. Demolition disposal, permit fees, and fixture procurement should all be addressed in the written contract.
- Ask who is doing the work. General contractors often subcontract specialised trades. Know who will be in your home and confirm they are also insured and properly licenced.
Is a Bathroom Renovation Worth It in Scarborough?
In a competitive GTA real estate market, a professionally completed bathroom renovation can improve daily livability and support resale value. Mid-range renovations tend to offer a solid return compared to leaving a visibly dated bathroom in a home being prepared for sale. That said, over-improving relative to neighbourhood standards rarely pays off — a general contractor familiar with Scarborough's housing stock can help you calibrate the right scope for your goals and budget.
