Planning a bathroom renovation in Ontario can be exciting, but if you don’t think it through, it can also become expensive and frustrating. Whether you’re updating a powder room in Mississauga or completely redoing a master ensuite in Toronto, there are a few essential things to keep in mind.
At RM Renovation in Ontario, we’ve completed hundreds of bathroom remodels across the GTA. From code compliance to material selection, here’s what every Ontario homeowner should consider before picking up that sledgehammer.
Key Factors to Consider for a Successful Bathroom Renovation in Ontario
Planning a bathroom renovation in Ontario? Here’s a complete list of factors you must consider to ensure your remodel is functional, code-compliant, and stress-free.
1. Know the Ontario Building Code Requirements
If you’re thinking about moving plumbing lines, adding a new shower, or installing heated floors, chances are you’ll need permits. You also want licensed trades on the job; it’s not something you can DIY without risks.
And according to expert plumbers from Anta Plumbing in Ontario, skipping permits or hiring unqualified contractors can lead to failed inspections, hidden leaks, or even mould problems later. If you’re relocating fixtures, adding outlets, or changing structural elements, always check if your municipality requires approvals.
At RM Renovation, we handle this part for you. We coordinate with inspectors, file the permits, and work with certified professionals, so your renovation stays compliant from day one.
2. Set a Realistic Budget (and Include a Safety Net)
Costs for a bathroom renovation in Ontario can vary widely depending on the room size, finishes, and how much structural work is involved. On average, homeowners in the GTA spend anywhere from $12,000 to $25,000.
We always recommend setting aside a little extra, usually around 10–15%, for things that don’t show up until demolition starts. It could be rotten subflooring, outdated plumbing, or electrical systems that aren’t up to code. Having a financial buffer makes it easier to deal with surprises without stalling the project.

3. Focus on Function First
Looks are important, but your bathroom should work for your everyday routine. Maybe the current layout makes the space feel cramped, or you don’t have enough storage. Some homeowners need a walk-in shower, while others want a tub for the kids.
Think about how your family uses the space and what really needs to change. Design trends come and go, but comfort and functionality will always matter. We help clients across the GTA strike that balance, so their bathrooms are as usable as they are stylish.

4. Choose the Right Materials for Ontario Conditions
Bathrooms deal with constant moisture, and in Ontario, we also have to factor in dry winter air and humid summers. That’s why it’s important to use materials built to last.
For flooring and walls, porcelain or ceramic tile is ideal. Behind your shower or vanity, moisture-resistant drywall is a must. Underneath, we use waterproofing membranes to prevent hidden leaks. Quartz countertops are popular for their low maintenance and durability. Our flooring and tiling specialists can help you choose the best materials for your space.
If you want to reduce water usage and utility bills, consider low-flow fixtures; you might even be eligible for rebates depending on your location.

5. Don’t Overlook Ventilation
A lot of homeowners forget how important ventilation is until they end up with mould on the ceiling or peeling paint. Bathrooms need a proper exhaust fan that vents to the outside, not into your attic or another room.
We often see older homes in Toronto and Mississauga with outdated or non-functioning fans. That’s something we always inspect and upgrade if needed. Good airflow protects your finishes and keeps your air clean.

6. Set Realistic Timelines
On average, a bathroom renovation takes about two to four weeks. It depends on the size of the space, the complexity of the work, and how quickly materials arrive. Permits can sometimes delay the start, especially in cities like Toronto or Vaughan.
At RM Renovation, we assign a project manager to every job. That means you’re never left guessing about timelines or waiting for trades to show up. You’ll get progress updates throughout, so everything stays on track.

7. Keep Resale in Mind
Even if you’re not planning to move right away, a well-done bathroom can increase your home’s value and appeal. Buyers appreciate modern finishes, smart lighting, and updated plumbing. In Ontario, a quality bathroom renovation can return up to 75% of its cost when it’s time to sell.
If resale is part of your long-term plan, we can help you make choices that look good now and stay timeless for years to come. Consider pairing your bathroom update with kitchen renovation to maximize your home’s value.
8. Add Some Comfort Features
Sometimes it’s the small touches that make your bathroom feel like a retreat. Heated floors, soft-close drawers, LED mirror lighting, or a niche shelf in the shower can elevate the space without a high extra cost.
Whether you’re aiming for practical upgrades or adding a bit of luxury, we can help you decide which features give you the most value and daily comfort. Our team also specializes in living and bedroom renovations if you want to extend comfort upgrades throughout your home.
9. Choose a Local Contractor Who Knows Ontario Homes
Renovating a bathroom in Ontario isn’t just about design; it’s about knowing the rules, materials, and what to expect in the homes we work on. Older Toronto homes have quirks. Newer builds in Vaughan or Oakville come with different expectations.
With more than 20 years in the business, our trusted team in GTA knows the ins and outs of every kind of project across the GTA. We handle the heavy lifting so you can enjoy the results.
