How Much Does a Bathroom Renovation Cost in Markham? (2026 Cost Guide)
If you’re planning a bathroom renovation in Markham, one of the first questions you’ll ask is: “How much is this actually going to cost?”
The honest answer is that bathroom renovation costs vary significantly based on the size of the space, the quality of finishes, the age of the home, and whether you’re keeping the existing layout or redesigning it entirely.
After more than 20 years renovating bathrooms across Markham and the wider GTA — from established neighbourhoods like Unionville and Markham Village to newer subdivisions like Cornell, Wismer, and Berczy Village — we’ve learned that homeowners are often surprised by what truly drives the cost. Two bathrooms that look nearly identical on paper can have dramatically different price tags depending on what’s happening behind the walls.
This guide breaks down realistic bathroom renovation costs in Markham for 2026, explains what affects pricing, and shares the things we’ve learned from completing hundreds of bathroom projects in this community.
Typical Bathroom Renovation Costs in Markham (2026)
While every project is unique, most bathroom renovations in Markham fall into one of three categories.
Basic Bathroom Renovation
Typical investment: $14,000 to $18,000+
This level generally includes:
- Keeping the existing layout
- Replacing fixtures and finishes
- New vanity
- New toilet
- New flooring and tile
- Fresh paint
- Updated lighting
This is often the most cost-effective approach because major plumbing relocation and structural changes are avoided. It’s a strong choice for newer Markham homes — Cornell, Wismer, Cathedraltown — where the existing layout works well and the homeowner wants a refreshed look without rebuilding from scratch.
Mid-Range Bathroom Renovation
Typical investment: $18,000 to $25,000+
This is the most common bathroom renovation category we see throughout Markham. Projects in this range typically include:
- Larger custom shower
- Higher-end tile selections
- Custom glass enclosure
- Improved lighting plan
- Better storage solutions
- Upgraded plumbing fixtures
- Enhanced waterproofing systems
Many homeowners choose this level because it balances long-term value, functionality, and aesthetics. It’s especially common in established Unionville and Markham Village homes where homeowners want to bring a 1980s or 1990s bathroom fully into the modern era.
Luxury Bathroom Renovation
Typical investment: $25,000 to $65,000+
A luxury bathroom renovation in Markham typically includes:
- Complete layout redesign
- Freestanding tub
- Heated floors
- Custom vanities
- Large-format tile
- Premium fixtures
- Extensive glass work
- Specialty lighting
- High-end finishes throughout
Some master ensuite and spa-style projects exceed this range, particularly in Angus Glen, Berczy Village, and Cathedraltown homes where the owners want a true retreat experience.
What Actually Drives Bathroom Renovation Costs?
Many homeowners assume the fixtures themselves are the biggest expense. In reality, bathroom renovations are one of the most labour-intensive renovations you can do in a home — and that labour is where most of the cost lives.
The largest cost drivers are:
1. Plumbing Relocation
One of the biggest factors affecting cost is whether plumbing stays where it is. Keeping your shower, toilet, and vanity in their existing locations helps control costs significantly.
Moving plumbing typically requires:
- Opening floors
- Reworking drains
- Adjusting venting
- Coordinating multiple trades
A bathroom that looks similar on paper can become significantly more expensive the moment plumbing locations change. We always walk Markham homeowners through these implications before any layout decisions are finalized.
2. Tile Selection
Tile affects both material cost and labour cost. Specifically:
- Larger tiles often cost more per square foot
- Specialty patterns require more labour to install
- Feature walls increase installation time
- Complex layouts create additional cutting and waste
Many homeowners focus only on the tile price tag and overlook the installation complexity that comes with premium selections. The right tile choice balances aesthetic goals with the labour cost it creates.
3. Glass and Shower Systems
Custom glass enclosures are one of the most requested upgrades in modern bathroom renovations. They create a beautiful, open, finished product — but they can add several thousand dollars compared to standard shower configurations. This is one of the cleanest “luxury feel for moderate cost” upgrades you can make.
4. Heated Floors
Heated flooring continues to grow in popularity across Markham. Many of our clients call it the single best upgrade they make, especially during Ontario winters when stepping onto a warm floor in the morning becomes a small daily luxury.
5. Age of the Home
Older Markham homes — particularly in Unionville and Markham Village — often present surprises once demolition begins. This can include:
- Water damage behind tile and drywall
- Previous renovation mistakes
- Plumbing deficiencies
- Structural issues
- Outdated electrical systems
These conditions aren’t always visible during planning, and they’re one of the reasons we always recommend building a contingency into the budget for older homes.
Why Bathroom Renovation Quotes Can Vary So Much
One of the most common questions we hear is: “Why did one contractor quote $25,000 and another quote $45,000 for what seems like the same bathroom?”
The honest answer is that the scope is usually not actually the same. A lower quote may quietly exclude:
- Waterproofing upgrades
- Certain demolition work
- Electrical improvements
- Plumbing modifications
- Permit requirements
- Finishing details
- Disposal costs
In many cases, homeowners don’t discover these differences until construction begins — and then it’s too late to switch contractors without significant cost and delay.
This is why we strongly recommend comparing detailed scopes of work, not just bottom-line numbers. A transparent, line-by-line quote tells you exactly what you’re paying for and protects you from “surprise” change orders later. Learn more about how we structure our quotes in our renovation process.
Hidden Costs Homeowners Don't Expect
Bathroom renovations are unique because much of the most important work happens behind finished surfaces. Until walls, floors, and ceilings are opened, certain conditions remain unknown.
Some of the most common discoveries:
Water damage. Years of moisture exposure can quietly destroy framing and subfloor behind tile and drywall.
Improper previous renovations. We’ve opened up bathrooms where previous contractors skipped important steps — missing waterproofing layers, undersized plumbing, incorrectly installed exhaust fans.
Plumbing issues. Older plumbing systems occasionally require updates to support modern fixtures and meet current code.
Electrical upgrades. Many older Markham bathrooms were not designed to handle today’s lighting, ventilation, and electrical requirements — adequate GFCI circuits, proper bath fan venting, etc.
These issues don’t occur on every project, but they should be factored into the budget when renovating older homes. We typically recommend a 10-15% contingency for homes built before 1990.
Common Bathroom Renovation Mistakes Markham Homeowners Make
After two decades of renovation work in this community, a few mistakes appear over and over.
Choosing based on price alone. The lowest quote is rarely the best value. It’s important to understand exactly what is included and excluded before signing.
Underestimating the budget. Many homeowners start with unrealistic expectations based on outdated pricing they found online. Construction costs, materials, and labour have changed significantly over the last several years.
Ignoring functionality. Beautiful bathrooms should work well for everyday life. Storage, lighting, layout, and accessibility often matter far more long-term than trendy finishes.
Focusing only on visible finishes. Tile and fixtures get the attention — but waterproofing, ventilation, and proper installation matter equally and often determine whether your renovation lasts 5 years or 20.
How Long Does a Bathroom Renovation Take in Markham?
Bathroom renovations require careful coordination between multiple trades. Timelines vary based on scope, but a realistic range is:
- Basic renovation: 2-3 weeks
- Mid-range renovation: 3-6 weeks
- Luxury renovation with layout changes: 6-12 weeks
The timeline depends on:
- Scope of work
- Material availability
- Custom product lead times (vanities, glass, premium tile)
- Plumbing or structural modifications
- Inspection scheduling
- Hidden conditions discovered during demolition
A professionally managed renovation prioritizes quality and proper sequencing over rushing the process. We provide every Markham client with a detailed schedule before work begins so you know exactly what to expect each week.
Are Permits Required for a Bathroom Renovation in Markham?
Not every bathroom renovation requires permits. However, permits may be necessary when:
- Plumbing is being relocated
- Structural changes are involved
- Significant building modifications are made
- Specific code-related work is required
The City of Markham’s building department reviews permit applications and requires inspections at key construction stages. Electrical work must also comply with Electrical Safety Authority (ESA) standards and inspections.
Working with an experienced Markham renovation company ensures the work is completed safely, permitted properly, and inspected to current standards — protecting both your home and your investment.
What Should You Budget for a Good Bathroom Renovation in Markham?
If you’re looking for a realistic number to anchor your planning, most Markham homeowners today should expect to invest:
- $14,000 to $18,000+ for a basic bathroom renovation
- $18,000 to $25,000+ for a quality mid-range renovation
- $25,000 to $65,000+ for a luxury bathroom renovation
The final number depends heavily on the selections you make and whether layout changes are involved. We always recommend an in-home consultation before committing to a budget — bathroom conditions vary enough that a real walkthrough produces a far more accurate estimate than any online calculator.

Keeping plumbing in its existing location is the biggest factor in keeping the cost in this range.

It does not usually include layout changes, custom millwork, heated floors, or premium tile.
Do I need a permit for a bathroom renovation in Markham?
