Bathroom Contractors Near You: Who Actually Has Credentials

Most bathroom remodel companies near you look identical on the surface — a polished website, before-and-after photos, glowing reviews. But when ProScore scored 536 Ontario bathroom remodelers against verifiable credentials, a striking gap emerged: only 96 of those 536 carry confirmed WSIB registration. That single number should change how you evaluate every quote you receive.

What the ProScore Data Actually Shows

ProScore has scored 536 bathroom remodeling contractors operating in Ontario. Across that group, fewer than one in five — just 96 — carry a verified WSIB registration in our corpus.

That is not a comment on the quality of the work these contractors do. It is a signal about verifiable business accountability. WSIB registration is one of the clearest, most checkable markers of a contractor running a legitimate operation in Ontario. When it is missing, you carry more risk than you probably realize.

For context on what these scores reflect, you can read about how the ProScore Trust Index works.

Why WSIB Registration Matters More Than You Think

WSIB — the Workplace Safety and Insurance Board — is Ontario's mandatory workplace insurance program. In Ontario's construction industry, WSIB registration is required for all contractors and subcontractors, including sole proprietors with no employees. It is not optional.

Here is the part that surprises most homeowners: if a contractor working in your home is not registered and gets injured on the job, you — as the property owner — can be held liable for unpaid WSIB premiums and costs. According to WSIB compliance guidance current for 2026, if a contractor's premiums lapse, unpaid amounts can become the homeowner's liability.

A bathroom renovation is an intimate project. Workers are in your home for days or weeks, handling water lines, electrical connections, and structural elements. WSIB registration is the baseline check that confirms the person in your home is running a legitimate business.

The good news: you can verify any contractor's WSIB clearance status for free, in minutes, through the WSIB's online clearance tool. Ask your contractor for their WSIB account number, then confirm their status yourself before work begins.

The Credential Landscape for Bathroom Renovation in Ontario

Bathroom remodeling is not a provincially licensed trade in Ontario. There is no provincial general contractor licence for renovation work — as confirmed by Ontario contractor licensing guidance. This means anyone can legally call themselves a bathroom renovation contractor.

That does not mean credentials are irrelevant. It means you have to look for the right ones.

Here is what to check, by the work being done:

Note: The HCRA (Home Construction Regulatory Authority) licenses Ontario's new-home builders under the New Home Construction Licensing Act, 2017. Its public builder verification tool at hcraontario.ca is useful if you are buying a new build — but it does not cover renovation-only contractors. Do not use it to vet a bathroom remodeler; it will not return results for them.

What the Credential Gap Means for Your Quote

A mid-range Ontario bathroom renovation — new tile, tub or shower, vanity, toilet, lighting, within the same footprint — typically costs $20,000–$40,000 in 2026. A powder room runs $8,000–$20,000. A master ensuite can reach $75,000 or more. GTA skilled trades charge approximately $80–$130 per hour, with general labour at $55–$80 per hour; Toronto projects run roughly 20–25% higher than the provincial average.

At those price points, the difference between a contractor with verified credentials and one without is not a minor detail. It is the difference between a project that is insured, permitted, and legally protected — and one that is not.

A lower quote from an unverified contractor is not a deal. It is a transfer of risk onto you.

One more thing worth knowing: if your bathroom renovation includes energy-efficient upgrades — better insulation, a heat pump, or qualifying windows — Ontario's Home Renovation Savings Program may offer rebates. The program, co-delivered by Save on Energy and Enbridge Gas with Ontario government support, includes rebates for insulation, heat pumps, windows and doors, smart thermostats, and eligible ENERGY STAR appliances. A contractor who understands these programs can help you capture savings you would otherwise leave on the table. Check current eligibility at saveonenergy.ca.

FAQ

Why do so few bathroom remodelers have verified WSIB registration?

Of the 536 Ontario bathroom remodelers ProScore has scored, only 96 carry confirmed WSIB registration in our corpus. Bathroom renovation is not a provincially licensed trade, so there is no automatic credential-check gate that contractors must pass to operate. Many small operators — and some larger ones — simply do not maintain the documentation that makes their credentials verifiable. That does not mean they are doing bad work, but it does mean you cannot confirm their accountability through public records without asking directly.

What happens if a contractor working in my home is not WSIB-registered?

If an unregistered worker is injured on your property, you as the homeowner can be held liable for unpaid WSIB premiums and associated costs. Ontario's construction rules make WSIB registration mandatory for contractors and subcontractors, but enforcement falls on the hiring party — which, in a home renovation, is you. Always verify a contractor's WSIB clearance before work starts.

Do I need to check credentials separately for electrical and plumbing work in a bathroom reno?

Yes. Even if your general bathroom contractor is fully credentialed, the sub-trades doing electrical and plumbing work must hold their own regulated credentials. Electricians must be registered with Skilled Trades Ontario and work under an ESA permit. Plumbers must also be registered with Skilled Trades Ontario. Ask specifically who is doing each type of work, and verify their credentials independently.
