Bathrooms are the renovation GTA homeowners ask us about most, and they are also the one people find hardest to budget for. A neighbour spends $14,000. A colleague spends $40,000. Both say they “renovated the main bathroom.” So, how much does a bathroom renovation cost in the GTA?
This guide gives you realistic 2026 price ranges for the Greater Toronto Area, shows exactly where the money goes, and — most importantly — explains why two quotes for what looks like the same job can be $10,000 apart. That last part is what actually protects your budget.
Bathroom renovation cost in the GTA at a glance
Bathroom costs are driven by size, whether the layout moves, the tile and fixtures you choose, and the condition of what is behind the walls. Here is what GTA homeowners typically invest in 2026.
| Type of bathroom renovation | Typical GTA cost (2026) |
|---|---|
| Powder room / two-piece | $8,000 – $15,000 |
| Small full bathroom, same layout | $16,000 – $25,000 |
| Mid-range main bathroom | $25,000 – $40,000 |
| Primary ensuite | $35,000 – $65,000 |
| High-end / spa ensuite | $65,000 – $120,000+ |
At Remodel My Home, our full-service bathroom renovations start at $15,999. That covers a complete, professionally managed renovation of a standard bathroom — demolition, waterproofing, tile, fixtures, vanity, lighting, paint and final finishing — with the permits and trades coordinated for you. Where your own project lands above that depends on size, whether the layout changes, and the finishes you choose.
Where your money actually goes
A bathroom is the most trade-dense room in your house. In roughly 40 to 100 square feet you have plumbing, electrical, ventilation, waterproofing, tile, carpentry and glass, and most of those trades have to attend in a specific order. That sequencing, not the size of the room, is why bathrooms cost what they do per square foot.
| Line item | Share of a typical budget |
|---|---|
| Labour and project management | 40–50% |
| Tile and tile setting | 15–20% |
| Plumbing fixtures and rough-in | 12–18% |
| Vanity, counter and storage | 8–15% |
| Glass, shower doors and hardware | 5–10% |
| Waterproofing, electrical and ventilation | 5–10% |
Notice that labour dominates. That is the single most useful thing to understand about bathroom pricing: you are mostly buying skilled time and coordination, not materials. It is also why a quote that comes in dramatically low is usually not buying you a bargain on tile — it is buying you fewer hours, or less experienced ones.
Why two quotes for the same bathroom differ by $10,000
This is the question we get asked more than any other, and it is a fair one. Homeowners hand three contractors the same room and get numbers that look unrelated. Here is what is actually different between them.
1. The demolition scope is not the same
One contractor is planning to strip the room to the studs and subfloor. Another is planning to tile over the existing floor and leave the old shower base in place. Those are genuinely different projects, and only one of them lets you find and fix the rot, failed waterproofing or undersized venting that is often hiding in a thirty-year-old bathroom.
2. Waterproofing is invisible, so it is the easiest place to cut
A properly waterproofed shower uses a bonded membrane system, correctly sloped, with sealed corners, seams and penetrations, and a compatible drain assembly. A cheaper approach relies on the tile and grout to do work they were never designed to do. Both look identical the day the job finishes. One of them is still dry in eight years. If a quote is unusually low, this is very often where the difference sits.
3. Moving plumbing changes the whole job
Keeping the toilet, sink and shower where they already are is the single biggest cost saver available in a bathroom. Relocating them means opening floors and walls, rerouting supply and drain lines, meeting venting requirements and, in older GTA homes, often replacing sections of galvanised or cast iron pipe you did not know you had. Moving a single fixture can add several thousand dollars.
4. Tile drives labour, not just material cost
Homeowners compare tile by price per square foot, but the labour spread is much wider than the material spread. Large-format porcelain needs a dead-flat substrate and careful setting. Mosaics, herringbone, chevron and niche detailing multiply cuts and time. A $4 tile in a demanding pattern can easily cost more installed than a $12 tile laid in a simple stack.
5. Fixture tiers are enormously wide
A serviceable vanity, toilet and shower system can be specified for a few thousand dollars, or for well over twenty. Thermostatic valves, wall-mounted fixtures, custom glass, heated floors and integrated lighting all move the number. None of them are wrong — but a quote built around builder-grade fixtures is not comparable to one built around premium ones.
6. One quote includes things the other quietly leaves out
This is the most common cause of the gap. Permits, disposal and dumpster fees, protecting the rest of your home during construction, painting, trim, the glass enclosure, delivery, and the project management to sequence six trades in the right order — each of these is sometimes excluded from a low quote and surfaced later as an extra. An itemized estimate is the only reliable way to compare.
Bathroom renovation costs by room type
Powder rooms and two-piece bathrooms
With no shower or tub, there is no waterproofing assembly and far less tile, so powder rooms are the least expensive bathroom to renovate. Most GTA powder rooms land between $8,000 and $15,000. They are also the best room in the house to be adventurous in, because the small area keeps the cost of a bold tile or wallpaper choice contained.
Main and family bathrooms
This is the most common GTA bathroom project. A full renovation keeping the existing layout typically runs $16,000 to $25,000, while a mid-range renovation with better finishes, a new tub-shower assembly and updated lighting generally lands between $25,000 and $40,000. If the bathroom serves children or guests, durability and storage usually matter more than statement finishes.
Primary ensuites
Ensuites carry the widest range because expectations are highest. Double vanities, separate shower and freestanding tub, custom glass, heated floors and dedicated lighting all add up, and ensuites are more likely to involve layout changes. Most GTA ensuite renovations land between $35,000 and $65,000, with spa-level projects going well beyond that.
Basement bathrooms
Adding a bathroom to a basement is a different job from renovating an existing one, because drainage frequently sits below the sewer line. That can require breaking the concrete floor to run new drains or installing an up-flush or sewage ejector system. Budget accordingly: a new basement bathroom typically starts around $20,000 and rises quickly when concrete work is involved.
What pushes a bathroom renovation over budget
- Moving fixtures. Every relocated drain adds plumbing, framing and often floor work.
- What is behind the walls. Rot, failed waterproofing, knob-and-tube wiring and old galvanised pipe are common in GTA homes built before the 1980s.
- Structural changes. Removing a wall to enlarge the room brings framing, and sometimes engineering, into scope.
- Custom glass. Made-to-measure frameless enclosures are a meaningful line item on their own.
- Long material lead times. Specialty tile and imported fixtures can stall a schedule, and schedule is cost.
- Mid-project changes. Decisions changed after demolition are the most expensive kind, because work already completed has to be undone.
What keeps a bathroom renovation affordable
- Keep the layout. If the current arrangement works, leaving plumbing where it is protects the budget more than any other decision.
- Choose simple tile patterns. Spend on the tile you love and lay it in a straightforward pattern; you keep the look and lose the labour premium.
- Mix fixture tiers. Put the money into what you touch daily — the shower valve, the vanity, the faucet — and be practical elsewhere.
- Decide everything before demolition. A finalised selection list is the cheapest project-management tool that exists.
- Renovate more than one bathroom together. Trades already mobilised on site cost less per room than two separate projects.
How long does a bathroom renovation take?
Most GTA bathroom renovations take about two to four weeks on site. A powder room can be finished in one to two weeks; a large ensuite with layout changes and custom glass can run five to six. Glass is worth planning for specifically, because frameless enclosures are usually measured only after the tile is set, then fabricated, which typically adds one to two weeks near the end.
Design and material lead times sit before all of that. Realistically, from first consultation to finished bathroom, plan on six to twelve weeks in total.
Do you need a permit for a bathroom renovation in Ontario?
Replacing fixtures in their existing locations, retiling and installing a new vanity generally does not require a building permit. You will typically need one when you move or add plumbing fixtures, alter structure such as removing or relocating a wall, or add an entirely new bathroom — including a bathroom in a basement.
Requirements and interpretations vary between municipalities, so confirm with your local building department, or work with a contractor who handles the permit process for you. Skipping a permit that was required can complicate an insurance claim and will usually surface during a future sale.
How to compare bathroom quotes properly
Ask every contractor for an itemized estimate rather than a single number, and check that each one specifies the same demolition scope, the same waterproofing system by name, whether permits are included, who supplies the fixtures and glass, and what the payment schedule looks like. When the quotes are itemized, the $10,000 gap almost always turns out to be explainable — and once you can see it, you can make a genuine decision rather than a guess.

Bathroom renovation cost FAQs
How much does a bathroom renovation cost in the GTA?
Most bathroom renovations in the Greater Toronto Area cost between $8,000 for a powder room and $65,000 or more for a large primary ensuite. A full renovation of a standard main bathroom typically lands between $16,000 and $40,000. Our full-service bathroom renovations start at $15,999.
Why are bathroom quotes so different from each other?
Usually because they are not quoting the same work. The most common differences are demolition scope, the waterproofing system used, whether plumbing is being moved, tile pattern and labour, fixture tier, and whether permits, disposal, painting and glass are included. An itemized estimate makes the gap visible.
What is the most expensive part of a bathroom renovation?
Labour and project management, typically 40 to 50 percent of the budget. A bathroom packs plumbing, electrical, waterproofing, tile, carpentry and glass into a very small space, and those trades have to be sequenced correctly.
Is it cheaper to keep the bathroom layout the same?
Significantly, yes. Leaving the toilet, sink and shower in their existing positions avoids rerouting supply and drain lines, opening floors and walls, and meeting new venting requirements. It is the single most effective way to control a bathroom budget.
How long does a bathroom renovation take?
Most GTA bathroom renovations take two to four weeks on site, with powder rooms closer to one to two weeks and large ensuites running five to six. Allow six to twelve weeks overall once design and material lead times are included.
Do I need a permit to renovate a bathroom in Ontario?
Not usually for a like-for-like refresh where fixtures stay in place. You generally do need one to move or add plumbing fixtures, change structure, or add a new bathroom such as one in a basement. Confirm with your municipality, or use a contractor who manages permits for you.
How much does it cost to add a bathroom in a basement?
Typically from around $20,000, and higher when drainage sits below the sewer line. That situation requires either breaking the concrete floor to run new drains or installing an up-flush or sewage ejector system, both of which add meaningful cost.
Do bathroom renovations add value to a home?
Bathrooms are consistently among the strongest returning renovations in the GTA, both for resale and for daily use. Dated bathrooms are one of the first things buyers notice, and an updated, well-built bathroom removes an objection that otherwise gets priced into offers.
