How Much Does It Cost to Renovate a Bathroom in Ontario? (Real Contractor Breakdown)

If you’re planning a bathroom renovation in Ontario, one of the first questions you’ll ask is: “How much is this actually going to cost me?”

The honest answer is—it depends on scope, finishes, and what we uncover once the walls open up. But based on real projects across Uxbridge, Durham, York Region, and Kawartha Lakes, here’s a clear breakdown of what you can realistically expect.

At Markway Homes, we don’t price bathrooms off a square foot rate. Every renovation is unique, and pricing reflects the actual condition of your home, your selections, and the scope of work involved.

Bathroom Renovation Cost Breakdown (Ontario 2026)

Here’s what we typically see in real-world projects:

Basic Bathroom Refresh: $8,000 – $15,000

A basic refresh is all about updating the look without major construction.

Typically includes:

• New paint

• New vanity

• New faucets

• New mirror

• New toilet

• New shower faucet

This is best for bathrooms where the layout stays the same and everything is in decent condition behind the walls.

Mid-Range Bathroom Renovation: $18,000 – $27,000

This is the most common range for homeowners doing a full “proper” bathroom update.

Typically includes everything above, plus:

• New tile flooring

• New shower tile

• New bathtub

• More trades involved (tile, plumbing, etc.)

This level adds more complexity, especially with waterproofing, tile work, and scheduling multiple trades.

High-End / Full Bathroom Gut: $30,000 – $50,000+

This is where bathrooms become custom spaces rather than just renovations.

Typically includes:

• Layout changes or plumbing relocation

• Enlarged or custom shower designs

• Large-format tile and upgraded finishes

• Custom glass showers

• Heated floors

• Custom vanities or cabinetry

• Possible sauna or luxury ensuite features

At this stage, the bathroom is often being rebuilt from the ground up—sometimes including structural or subfloor corrections.

What Actually Drives Bathroom Renovation Cost?

If you’re trying to estimate your budget, these are the biggest factors that impact price:

1. Tile Selection & Design Complexity

Tile is one of the biggest cost drivers. Large-format tile, intricate patterns, and custom layouts increase labour significantly.

Even something like a shower floor can shift costs quickly—larger tiles often require:

• Precision cutting for drainage slope

• Or upgrading to a linear drain system

• 
  

2. Bathroom Size & Coverage Area

Simply put: more surface area = more labour, materials, and time.

3. Plumbing Relocation

Moving plumbing through floors or walls (especially in older homes) adds complexity:

• Cutting and repairing joists

• Re-routing drains and water lines

• Opening walls and subfloors

• 
  

4. Age of Home (Hidden Damage)

If your home is 20–30+ years old, there is a high chance of:

• Water damage behind walls

• Rotting subfloors

• Mold behind drywall

• Uneven floors requiring correction

These are not “extras”—they’re often uncovered once demolition begins.

Where Homeowners Often Get Surprised

Most people underestimate how much work goes into what looks like a “small bathroom.”

Common surprises include:

• Prep work taking longer than expected

• Multiple coats of paint increasing labour time

• Compatibility issues with fixtures (vanities, faucets, lighting, fans)

• Plumbing systems not matching modern fixtures (posi-temp vs standard valves)

This is why professional installation matters—because you don’t know what you’re dealing with until the walls come down.

Where People Often Overspend

From experience, homeowners tend to overspend in a few key areas:

• Custom niches and shower details (expensive for what they are)

• Custom vanities vs pre-built options (Home Depot vs millwork can be a big gap)

• Large shower floor tiles (turns into custom slope work or requires linear drains)

These aren’t bad upgrades—but they can push budgets up quickly without necessarily improving function.

Real Bathroom Renovation Example (27K Ensuite)

We recently completed a ~100 sq ft ensuite renovation in the mid-to-high range.

Final cost: ~$27,000

Scope included:

• Full tile shower and flooring selection

• Mid/high-end finishes

• Shower rebuild due to ceiling being out of level

• Subfloor repair due to rot

• Custom-fit bathroom fan due to compatibility issues in an older home

There was an additional ~$1,000 in unexpected work, mainly from hidden structural issues—which is actually very controlled for a renovation of this type.

This is typical: once walls open up, small adjustments are normal.

Our Quoting Approach at Markway Homes

Every bathroom we quote is specific to that project. We do not use square-foot pricing because no two homes are the same.

We build pricing based on experience from previous renovations, but every quote reflects your exact bathroom.

How We Handle Surprises

Once walls are open, if we find issues, we:

• Assess the problem

• Review it with the homeowner

• Determine if it must be fixed (mold, rot, structural issues)

• Agree on pricing before proceeding

Nothing moves forward without approval.

Payment Structure (Designed to Reduce Stress)

Our payment process is staged to match project progress:

• Deposit to begin

• Payment on material arrival / major stage milestones

• Payments tied to trades (framing, drywall, plumbing, etc.)

• Final holdback until completion and homeowner satisfaction

This keeps expectations clear and protects both sides.

What Makes Our Approach Different

At Markway Homes, we focus on:

• Clean job sites daily

• Clear communication throughout the project

• Full walkthroughs during and after completion

• Attention to small details before final payment

• Fixing issues properly—even if it means sending trades back

If something isn’t right, we fix it. Simple as that.

Final Thoughts

Bathroom renovations in Ontario typically fall between $8,000 and $50,000+ depending on scope, finishes, and what’s behind the walls.

The biggest mistake homeowners make is underestimating:

• Labour time

• Hidden damage in older homes

• The impact of tile and plumbing decisions

If you’re planning a renovation, the best thing you can do is budget realistically and work with someone who is upfront about what can happen once demolition starts.
