Bathroom Renovation Cost Calculator Canada — Province by Province, Including the Tax You Cannot See
The same bathroom costs a different amount in Ontario, Alberta and British Columbia before a single tile is chosen — and in two provinces the tax on your invoice is not the tax you actually pay.
Educational calculators — always consult a licensed professional before making financial decisions.
Your bathroom
Tax follows the province the house is in, not the contractor's. The City of Toronto permit is priced only for Ontario with the Toronto market selected.
Sets the sales tax on the contract — the biggest Canadian cost you cannot negotiate.
HST 13% on the whole contract, labour included.
Toronto and Vancouver trades run materially above the rest of Canada for identical scope.
×1.25 labour. Permit computed exactly from the City's 2026 schedule.
Scope picks the Canadian national band; the bathroom type sets the fixture count the Toronto permit is charged on.
Fixture count drives both the plumbing work and the Toronto permit.
Toilet, sink, tub and shower. The band as published.
Canadian national bands for a full bathroom, in CAD, before tax.
Full strip and replace inside the existing footprint.
Keeping fixtures where they are is the biggest saving you control. Floor area is used only for the Toronto permit.
The single biggest cost you actually control.
No relocation cost. The predictable option.
Rot behind the tub surround and a failed subfloor are the two most common finds.
Recommended for any bathroom over about 25 years old.
Used only for the City of Toronto permit calculation.

What sales tax does to this job in Ontario
HST 13% applies to the whole contract — labour and materials alike. There is no separate provincial line and no exemption for labour.
Tax follows the province the house is in — not where you live, and not where your contractor is based. The same contract in Alberta would carry C$1,688 – C$2,688 instead of Ontario's C$4,388 – C$6,988.

Rot behind a tub surround and a failed subfloor are the two most common finds in a Canadian bathroom older than about twenty-five years. Nobody can tell you whether you have them until the tile is off.
Government schedule · shown, not added
City of Toronto minimum permit fee. At 50 sq ft with 4 plumbing fixtures the computed charge does not reach the C$214.79 floor, so the fee is flat. With 4 fixtures the crossover sits at about 98 sq ft — note that the more fixtures you have, the smaller the room can be before the fee starts to move. Shown for transparency but NOT added to the total: the national band above comes from a source whose own budget allocation already sets aside 5% for permits and contingency, so adding this again would charge you for it twice.
All figures in Canadian dollars (CAD). Sales tax treatment for every province and territory is quoted from a government source read 7 September 2026 — the Canada Revenue Agency for GST and HST rates, the Province of British Columbia and Manitoba Finance for the provincial taxes their contractors pay rather than charge, and Saskatchewan Information Bulletin PST-12 for the one province that taxes renovation labour outright. Quebec's QST rate is the single exception and is flagged above. Toronto permit fees come from the City's published 2026 schedule. Cost bands are Canadian market figures from Reno Quotes' 2026 bathroom guide (updated 13 April 2026). No US cost data is used anywhere in this model. Nothing is collected or stored — the calculator runs in your browser and there is no form.

The Canadian driver nobody prices: which province the house is in
A renovation is, in tax law, a service in relation to real property. That means the rate is set by where the house is — not where you live, and not where your contractor is based. On a C$36,875 bathroom contract the spread across Canada is more than C$2,900, and the ranking is not the one most people expect:
| Province | On the invoice | Visible tax (CAD) | Buried in the quote (CAD) | What you really pay (CAD) |
|---|---|---|---|---|
| Ontario | 13% HST | C$4,793.75 | — | C$4,793.75 |
| Saskatchewan | 5% GST + 6% PST | C$4,056.25 | — | C$4,056.25 |
| British Columbia | 5% GST | C$1,843.75 | C$1,032.50 | C$2,876.25 |
| Alberta | 5% GST | C$1,843.75 | — | C$1,843.75 |
All figures in Canadian dollars, on the same C$36,875 pre-tax contract. Rates read at their own government sources on 7 September 2026.
Why British Columbia is not the bargain it looks like
The Province of British Columbia states plainly that services related to real property are not subject to PST, and that a contractor does not charge customers PST for them. What it also states is that the contractor must pay PST on the goods that become part of real property — every tile, every fixture, every sheet of backer board. That 7% does not vanish. It is inside the number your contractor quotes you. Manitoba works the same way with its 7% RST. Saskatchewan does the opposite and charges 6% PST on the whole contract, labour included, as a separate line on the invoice.
What the arithmetic looks like on a real job
A main four-piece bathroom in Toronto, stripped and replaced within its existing walls, with the toilet and tub moved and an allowance for what turns up behind the tile:
| Line | Low (CAD) | High (CAD) | Basis |
|---|---|---|---|
| Standard renovation, main 4-piece bathroom | C$31,250.00 | C$47,500.00 | C$25,000–38,000 national × 1.25 GTA labour |
| Moving the plumbing | C$3,125.00 | C$6,875.00 | C$2,500–5,500 × 1.25 |
| Hidden-damage allowance | C$2,500.00 | C$6,250.00 | C$2,000–5,000 × 1.25 |
| Contract price, before tax | C$36,875.00 | C$60,625.00 | Sum of the three lines above |
| Ontario HST at 13% | C$4,793.75 | C$7,881.25 | On the whole contract, labour included |
| Out the door | C$41,668.75 | C$68,506.25 | Contract plus Ontario HST |
All figures in Canadian dollars. This example and three others — including the British Columbia comparison, an Alberta powder room, and the Toronto permit boundary — are written out long-hand in the header of src/lib/calculators/ca/bathroom-renovation.ts and pinned as tests, so the arithmetic can be checked without running the page.
The Toronto permit is almost always the same number
The City of Toronto's 2026 schedule charges C$13.41 per square metre for residential alterations plus C$23.20 per plumbing fixture in a single family dwelling, subject to a minimum fee of C$214.79. A 50 sq ft four-fixture bathroom computes to C$155.09 — comfortably under the floor — so the fee is C$214.79. The crossover for four fixtures sits at about 98 sq ft, and it drops to about 79 sq ft for a five-fixture ensuite, because the per-fixture charge eats the headroom before the area charge does. Most Canadian bathrooms never reach it.
What we refused to model
Every Canadian municipality publishes its own building permit schedule, and they are not comparable to one another — you cannot infer Calgary's from Toronto's. On 7 September 2026 only the City of Toronto's could be read at its own source. So outside Toronto this calculator returns “not modelled” and labels your total a floor rather than a budget. A number we cannot stand behind is worse than a gap we name.
The permit is also shown but not added to the total, even in Toronto. The Canadian cost source behind the scope bands states its own budget allocation — labour 55%, finishing materials 30%, rough materials 10%, permits and contingency 5% — so the permit is already inside the band. Adding an exact fee on top would charge you for it twice. Showing it anyway lets you check your contractor's line against the City's published rate.
Montréal prices its permit a completely different way
Toronto charges by area and fixture count. The City of Montréal does not — it charges C$9.80 per C$1,000 of declared construction value, subject to a C$167.40 minimum for a residential building, and the declared value has to reflect the real cost of both materials and labour, not just materials. On the same C$36,875 contract used in the worked example above, that computes to C$36,875 ÷ 1,000 × C$9.80 = C$361.38 — above Montréal's floor, and a different number from Toronto's C$214.79 flat fee on the identical job, because the two cities do not measure the same thing. Montréal also notes that some boroughs (arrondissements) add their own analysis fee on top, most often for heritage buildings or protected sectors, without publishing a citywide table of those amounts — so, like the non-Toronto municipalities below, a borough surcharge is not modelled here and the C$361.38 figure is a floor, not a guarantee.

How certain each number is
- ✓Government source — every sales tax rate and rule, and the Toronto and Montréal permit figures. Read at the Canada Revenue Agency, the Province of British Columbia, Manitoba Finance, the Government of Saskatchewan, the City of Toronto and the City of Montréal on 7–9 September 2026, with one exception named below.
- ·Estimated market band — the scope bands and the hidden-damage allowance. Canadian sources, dated on this page. No government schedule exists for these, because nobody publishes what a contractor charges.
- ·Derived — the powder-room and ensuite multipliers, scaled from fixture count because the source publishes bands for a full bathroom only; and the plumbing-relocation band, carried from the same Canadian publisher's kitchen guide because the bathroom guide does not price it. Both are the weakest figures here and are labelled as such on screen.
- ·Not modelled — permits outside Toronto, and any labour discount for Montréal or smaller centres. The cost source puts those markets below the national average but states no discount percentage, so none is applied and your estimate for them leans slightly high. Over-stating a budget by a stated amount beats inventing a discount.
- !One rate we could not confirm at source — Quebec's QST. Revenu Québec's published rate pages returned HTTP 403 on 7 September 2026, so the 9.975% figure is carried from this site's own Canadian tax module rather than quoted at the ministry. It is flagged in the results whenever Quebec is selected.
No US cost data appears anywhere in this model. American bathroom figures are widely republished and are not a proxy for Canadian ones at any exchange rate: the labour market is different, the permit instruments are different, and the entire sales-tax structure above has no US equivalent whatsoever.
Doing the kitchen too?
A kitchen is priced completely differently in Canada — by the linear foot of cabinetry, and by the carcass material those cabinets are made from, which is not the American stock / semi-custom / custom ladder at all. It gets its own model rather than a second scope band on this page.

Methodology
Line items are summed as low and high bands rather than collapsed to a point estimate, because a bathroom quote genuinely varies by that much. The regional labour adjustment of ×1.25 for Toronto and Vancouver is the bottom of the 25–40% premium the cost source publishes, and it is the same multiplier used by our basement calculator — using one figure across every Canadian renovation page is what stops the site quoting the same reader two different numbers for the same city.
Sales tax is applied to the contract price, which is how a Canadian renovation is actually invoiced. Where a province's provincial tax is borne by the contractor rather than charged to you — British Columbia and Manitoba — it is estimated at that province's rate against the 40% materials share the cost source publishes for a bathroom budget, and it is shown as a disclosure rather than added to your total, because it is already inside the quoted price. Four hand-worked examples in Canadian dollars, each with its province named and including the Toronto minimum-permit-fee boundary, are written out in the header of src/lib/calculators/ca/bathroom-renovation.ts and pinned in tests/calculators/ca-bathroom-renovation.test.ts.
All figures are in Canadian dollars and labelled C$ throughout, including the tables and the structured data. Nothing is collected or stored — the calculator runs in your browser and there is no form. This is a budgeting tool, not a quote; get three written quotes before you sign anything.

Frequently asked questions
How much does a bathroom renovation cost in Canada in 2026?
Nationally, an aesthetic update runs about C$18,000–24,000, a standard full replacement inside the existing footprint C$25,000–38,000, and a high-end renovation C$45,000 and up, all before sales tax. Toronto and Vancouver run roughly 25% above those figures. A standard main bathroom in Toronto with the plumbing moved and an allowance for hidden damage comes to about C$36,875–C$60,625 before tax, or C$41,668.75–C$68,506.25 once Ontario's 13% HST is added.
Do you pay HST or GST on a bathroom renovation in Canada?
Both, depending on the province — and the tax follows the province the house is in, not where you live or where your contractor is based, because a renovation is a service in relation to real property. Ontario charges 13% HST on the whole contract including labour. Nova Scotia charges 14% (reduced from 15% on 1 April 2025). New Brunswick, Newfoundland and Labrador and Prince Edward Island charge 15%. Alberta and the three territories charge GST 5% only. Saskatchewan charges GST 5% plus PST 6%. Quebec charges GST 5% plus QST 9.975%.
Why does a British Columbia renovation quote only show 5% tax?
Because British Columbia does not charge PST on services to real property — the Province's own guidance for real property contractors states that these services are not subject to PST and that contractors do not charge their customers PST for them. That does not mean you avoid the 7%. The contractor pays PST on every material bought for your job and prices it into the quote. On a C$36,875 bathroom contract, with materials at roughly 40% of the budget, that is about C$1,032 of BC PST you are paying without ever seeing it on an invoice. Manitoba works the same way with its 7% RST.
Which province is cheapest for a bathroom renovation once tax is counted?
Alberta, and it is the only province where the invoice tells the whole story — GST 5% and no provincial sales tax at all, visible or buried. British Columbia and Manitoba look equally cheap at 5% on the invoice but carry another 7% inside the contractor's price on materials. On an identical C$36,875 contract, Alberta's true tax burden is about C$1,844, British Columbia's about C$2,876, and Ontario's about C$4,794.
Do I need a permit for a bathroom renovation in Toronto, and what does it cost?
The City of Toronto's 2026 schedule charges C$13.41 per square metre for residential alterations plus C$23.20 for each plumbing fixture in a single family dwelling, subject to a minimum fee of C$214.79 for all work. For a bathroom the minimum almost always governs: a 50 sq ft four-fixture bathroom computes to C$155.09, well under the floor, so the fee is C$214.79. The crossover for a four-fixture bathroom is about 98 sq ft, and it falls to about 79 sq ft for a five-fixture ensuite because the per-fixture charge eats the headroom.
How much does moving the plumbing add to a bathroom renovation?
About C$2,500–5,500 before any regional adjustment, or roughly C$3,125–6,875 in Toronto or Vancouver. It is the single biggest cost in a bathroom that you actually control. Keeping the toilet, sink and tub in their existing positions means the drain and supply lines never move and the job stays predictable; moving them means breaking the floor, re-running services and making good — and in an older Canadian house that is also where the surprises are found.
Why does this calculator not show a permit fee outside Toronto?
Because those schedules could not be read at their own municipal sources on 7 September 2026, and every municipality prices permits differently, so no other city's figure can be inferred from Toronto's. A permit fee taken from a renovation blog is worse than no figure at all. Outside Toronto the line is shown as "not modelled" and the total is labelled a floor rather than a budget.
