Bathroom Renovation Cost Ontario 2026: Complete Price Guide

Cost Ranges by Scope

The price depends almost entirely on scope. A refresh and a full gut are completely different projects with completely different budgets. The Canadian Home Builders' Association's Renovation Market Index tracks contractor sentiment and pricing trends across the country each quarter, and 2025 readings confirmed that bathroom projects remained one of the most active categories despite overall renovation spending cooling.

Refresh ($3,000 to $8,000)

A cosmetic refresh keeps every plumbing fixture exactly where it is and replaces only what you see. New vanity, faucet, toilet, mirror, paint, and hardware. No tile demolition, no rough-in changes. Most projects in this tier finish in one to two weeks and require no permits, because nothing structural, electrical, or plumbing-related changes.

This is the only tier most homeowners can partially DIY without running into Ontario Electrical Safety Code or plumbing permit issues. Swapping a like-for-like faucet or toilet is routinely done by homeowners, but the moment you add a new circuit or move a drain, you are into regulated work. The Electrical Safety Authority's homeowner-DIY guidance spells out exactly what a homeowner can and cannot do without filing a notification, and the list is much shorter than most people assume.[5]

If you are tempted to stretch a refresh into a mid-range remodel halfway through, stop and re-budget before you start knocking out tile. The extra trades, permits, and lead times that come with a mid-range scope turn a two-week project into a five-week one very quickly, and the pricing changes accordingly. It is almost always cheaper to decide on one tier before you begin and stick to it than to escalate mid-project.

Mid-Range Remodel ($12,000 to $35,000)

The mid-range tier is where most Ontario bathroom renovations land. You are replacing the tub or shower with new tile, a new vanity and countertop, updated lighting and ventilation, and a new toilet. The plumbing stays in the same locations, so you avoid the biggest cost driver in a gut job. Timelines run three to five weeks, with the bulk of the labour concentrated in weeks two and three during tile work. You may still need a building permit depending on scope, and you will almost certainly need an ESA notification if you are adding a new exhaust fan circuit, pot lights, or a heated-floor thermostat. Expect two to three separate inspections across the project: plumbing rough-in, electrical rough-in, and final.

Gut Renovation ($30,000 to $70,000+)

A full gut renovation means everything comes out to the studs and subfloor. Plumbing gets relocated, walls may move, a curbless shower replaces a standard alcove tub, and the electrical service feeding the room gets upgraded. This tier almost always requires a municipal building permit and an ESA electrical notification, and the timeline runs five to eight weeks assuming no surprises behind the walls. Surprises are common in older Ontario homes: cast iron drain stacks that need replacement, knob-and-tube wiring in the joist bays above the ceiling, or subfloor rot under a leaking toilet flange. Any one of these can add $1,500 to $5,000 to the budget. A contingency of 10 to 15 percent on top of the contractor's quoted price is not optional on a gut job; it is how experienced renovators plan.

Fixtures vs Labour: Where the Money Actually Goes

One of the most common budgeting mistakes is assuming fixtures are the biggest cost. In a typical mid-range Ontario bathroom renovation, labour and related services (tile setting, plumbing, electrical, drywall, painting, waterproofing) represent 55 to 65 percent of the total. Fixtures and materials are the remainder. Statistics Canada's building construction price indexes show residential trade wages have been the fastest-rising input cost in the sector over the past several years, and that is the single biggest reason why a renovation that cost $15,000 a few years ago is closer to $22,000 today.

• Labour and trades: 55 to 65 percent of budget
• Tile, stone, and waterproofing materials: 10 to 15 percent (the range depends heavily on tile choice, with natural stone pushing this category toward the top end)
• Vanity, countertop, and fixtures: 15 to 20 percent
• Lighting, ventilation, and electrical: 5 to 10 percent
• Permits, inspections, disposal: 2 to 5 percent

Plumbing Rough-In and Relocation

Plumbing is the single biggest cost driver in any bathroom renovation, and the question is almost always the same: are you moving fixtures or leaving them where they are? The answer often decides whether a project costs $15,000 or $35,000.

• Same-location rough-in (like-for-like): $800 to $2,500 typical. Covers shutting off, disconnecting, and reconnecting existing fixtures.
• Toilet or shower drain relocation: $2,000 to $5,000. Usually requires opening the floor below to re-route waste and vent stacks.
• New rough-in (adding a bathroom): $5,000 to $12,000. Covers new supply lines, waste stacks, vents, and connection to existing plumbing.
• Supply line upgrades: $700 to $3,000 in older homes with galvanized steel or lead lines that need to come out.

Whenever plumbing fixtures are moved or added, your municipality requires a building permit. Ontario's consumer-protection guidance is explicit that homeowners are responsible for ensuring a permit is pulled even when a contractor is doing the work, and it is the homeowner who bears the consequences if work is done without one.[1]

Electrical Updates: GFCI, Ventilation, and Lighting

The Ontario Electrical Safety Code sets hard rules for bathrooms. All receptacles within 1.5 metres of a water source must be GFCI protected. Any new circuit requires an ESA notification filed before work begins, and it must pass inspection before the walls close up. The Electrical Safety Authority is explicit that homeowner DIY exemptions are narrow and do not cover most bathroom electrical upgrades.[4]

A typical mid-range bathroom gets two or three ESA inspections: an open-wall rough-in to check wire runs and boxes, a cover inspection once drywall is closed, and a final once fixtures are installed. Budget both the ESA notification fee and a small allowance for inspection re-visits if the first pass does not close out cleanly. The Electrical Safety Authority publishes the notification form and fee schedule online, and contractors file on the homeowner's behalf as part of a normal job.[6]

• GFCI-protected vanity outlets: $250 to $450 installed per location
• Exhaust fan on its own switch or timer: $300 to $700 (fan, wiring, timer control, ducting)
• Recessed pot lights (per light): $150 to $300 installed, more in finished ceilings
• Dedicated circuit for heated floors: $400 to $800
• ESA notification and inspection: typically $100 to $300 depending on scope

Tile and Waterproofing (and the OBC Rules)

Tile is usually the single largest line item, and it is also where cutting corners causes the most expensive failures later. The Ontario Building Code requires showers and tub surrounds to be finished in a non-absorbent material over a properly installed moisture barrier. This is not optional. A leak behind the wall causes mould and structural damage that costs far more than the renovation itself.[3]

• Ceramic tile: $8 to $15 per square foot (materials)
• Porcelain tile: $10 to $20 per square foot
• Large-format porcelain: $15 to $25 per square foot
• Natural stone (marble, slate): $20 to $40 per square foot
• Installation labour: $8 to $15 per square foot
• Waterproofing membrane (Schluter, Laticrete, etc.): $3 to $6 per square foot installed

For a standard 40 square foot shower surround in porcelain with a proper membrane, expect $900 to $1,800 all in. Natural stone over the same area runs $1,300 to $2,500. Modern large-format porcelain convincingly mimics marble and slate at roughly half the cost and with significantly less maintenance, and it is far more forgiving of hard water, a real consideration in most of Ontario where municipal water is moderately to very hard depending on region.

Vanity and Countertop Pricing

Vanities span a wide range because there are three distinct categories: stock units from big-box retailers, semi-custom, and fully custom millwork. The countertop and sink are often priced separately from the cabinet body.

• Stock vanity (big-box): $500 to $1,500
• Semi-custom vanity: $1,500 to $4,000
• Custom millwork vanity: $4,000 to $10,000+
• Quartz countertop: $60 to $120 per square foot installed
• Granite countertop: $50 to $100 per square foot installed
• Double vanity premium: add 50 to 80 percent to any of the above

A stock vanity from a reputable retailer can look perfectly fine in a standard bathroom. Custom millwork makes sense in primary ensuites where specific dimensions, drawer layouts, or an integrated look with the tile really matter.

Permit Requirements

Not every bathroom renovation needs a permit, but the ones that do are not ambiguous. Ontario's consumer-protection and home-renovation guidance is explicit about what triggers a permit and what happens when work is done without one.[2]

• Building permit required when you move or add plumbing fixtures, modify structural framing, or alter the building envelope (adding a window, for example).
• ESA notification required for any new electrical circuit or wiring change. This is filed with the Electrical Safety Authority before work starts.
• No permit required for painting, replacing a vanity in the same location, swapping a faucet, or installing new hardware.

If you hire a contractor, the homeowner is still the party on the hook when a permit is missed. Ontario's guidance to homeowners is clear: verify the permit was pulled and inspections were closed before final payment. Missed permits surface years later during a home sale and can hold up closing, force retroactive inspections, or in the worst case require the work to be opened back up and redone to code.

Ventilation and the OBC 9.32 Rule

The Ontario Building Code requires mechanical ventilation in every bathroom. Section 9.32 sets the framework, and the fan must vent directly to the exterior, not into an attic or soffit. Natural Resources Canada's home ventilation guidance emphasizes the same point from a moisture-management perspective: without properly ducted exhaust, bathroom humidity migrates into wall and ceiling cavities and creates ideal conditions for mould.[7]

• Standard exhaust fan (80 to 110 CFM): $200 to $500 installed with ducting
• Quiet / premium fan (Panasonic, Broan): $400 to $800 installed
• Fan with humidity sensor or timer: $500 to $900
• Venting through roof vs. through wall: roof penetrations add $200 to $500 in labour

Accessibility Additions

Ontario's population is aging, and bathroom accessibility upgrades are one of the fastest-growing segments of the renovation market. CMHC's Improvement Mortgage Loan Insurance program is one financing route homeowners use to fold these upgrades into a larger renovation, and the Appraisal Institute of Canada's renovation guidance notes that aging-in-place features increasingly preserve resale value rather than detract from it.[10]

• Curbless walk-in shower: $8,000 to $15,000 (requires custom floor drain and waterproofing work)
• Grab bars: $200 to $500 installed per bar (blocking should be added behind drywall during renovation)
• Comfort-height toilet: $400 to $700 installed
• Wider doorway (24" to 32" or 36"): $300 to $800
• Non-slip tile flooring: minimal cost premium, just specify a higher coefficient of friction
• Handheld showerhead on slide bar: $150 to $400

Even if you do not need these features today, adding blocking behind the walls for future grab bars costs almost nothing during a renovation. It is one of the smartest things you can do while the walls are open.

Timeline: How Long Each Tier Takes

• Cosmetic refresh: 1 to 2 weeks
• Mid-range renovation: 3 to 5 weeks
• Full gut renovation: 5 to 8 weeks
• Condo projects: add 1 to 2 weeks for building approvals and noise-bylaw scheduling

The most common cause of delays is not the contractor; it is tile and custom vanity lead times. Imported or specialty tile can take four to eight weeks to arrive. Order materials before demolition starts, not during it.

ROI on Ontario Housing

The Appraisal Institute of Canada's homeowner guidance makes the same point every year: mid-range bathroom updates recoup a higher share of their cost than luxury gut jobs. The highest-impact, best ROI changes are a clean tile surround, a new vanity and countertop, updated lighting, fresh paint, and a modern toilet. Over-personalizing with unusual colours, oversized fixtures, or hyper-custom layouts typically reduces resale value relative to the money spent.[8]

The second lesson from the AIC guidance is equally important: consistency across the home matters more than any single room. A spectacular ensuite attached to a dated hallway and a worn-out powder room does not pull the house's overall value up as much as you would expect. If you are renovating for resale, budget for consistency. If you are renovating to enjoy the home, spend where you use the space most.

CMHC's Improvement Mortgage Loan Insurance program is worth knowing about if you are buying a home that needs work. It lets qualified buyers roll the cost of improvements into the mortgage at purchase, which can make a bathroom gut renovation financially easier than paying for it after closing.[10]

Where to Save and Where Not To

Good Places to Save

• Keep plumbing in place. Moving a toilet or shower drain three feet across the room can add $2,000 to $5,000.
• Stock vanity over custom. The quality gap between a $1,200 stock vanity and a $4,000 custom unit is smaller than most homeowners expect.
• Porcelain over natural stone. Modern porcelain convincingly mimics marble and slate at half the cost and with less maintenance.
• Standard alcove tub over freestanding. If you need a tub at all, an alcove model at $800 to $2,000 does the job for a fraction of a freestanding soaker.

Do Not Cut Corners On

• Waterproofing. A proper shower membrane is non-negotiable. A leak behind the wall causes mould and structural damage that dwarfs the cost of the renovation.
• Ventilation. A properly ducted, properly sized fan prevents moisture damage. It is both a code requirement and a practical necessity.
• Electrical work. File the ESA notification. Get the inspection. The penalties and liability for unpermitted electrical work are significantly worse than the cost of doing it properly.
