In Gatineau, Quebec, a standard-quality bathroom renovation typically costs between $6,438 and $15,660 in 2026 — prices are below the Canadian average, with a local cost index of 87%. Expect around 2 to 5 weeks of work and a 60–70% return on investment at resale. Plumbing lines on exterior walls are a freeze risk — rerouting them inward during a kitchen or bath renovation is the single best durability investment you can make.
Same job in Ottawa: $7,104 – $17,280 at standard quality, about 10 % more expensive than Gatineau on our cost index.
A Gatineau bathroom is quoted with Ottawa in the next breath: same contractors, often, but 14.975 % GST + QST instead of 13 % HST once the invoice comes, and an RBQ licence required of anyone who works on the Québec side. The house matters more than the sector for the price: pre-1960 homes in Hull and Aylmer are likelier to hide cast-iron drains behind the wall than newer houses in the Plateau or Buckingham, so ask for a contingency line. Under $26,000 of work the city generally asks no permit unless structure or interior walls move.

Bathroom renovations have the highest cost-per-square-foot of any room due to the concentrated plumbing, waterproofing, and ventilation requirements. Plan for a minimum 2-week period without access to the bathroom — arrange alternative facilities. Waterproofing (Schluter, Kerdi, or liquid membrane) is the most critical investment; a leak behind tiles can cause $10,000+ in hidden damage. Choose tiles before finalizing the layout, as tile sizes affect wall and floor planning.
Tile work (materials + labour) typically represents 25–35% of a bathroom renovation budget. Walk-in showers cost $3,000–$8,000 more than standard tub/shower combos. Heated floors add $500–$1,500 but are highly desirable in Canadian climates. Moving a toilet location adds $1,500–$3,000 due to drain relocation.
Pro tip
If your budget is tight, focus spending on the shower area (waterproofing + nice tile) and vanity — these are what buyers and guests notice most. Save on accessories, mirrors, and paint, which are easy to upgrade later.
Gatineau is priced with Ottawa in the next breath: many contractors serve both sides of the river, but a job in Gatineau carries GST + QST rather than HST and requires an RBQ licence. The housing runs from older homes in Hull and Aylmer to newer developments in the Plateau and Buckingham; on our cost index Gatineau sits below Ottawa.
Gatineau gets Ottawa's cold winters and heavy snow, and more snow toward the Gatineau Hills. Spring flooding from the Ottawa and Gatineau rivers has been severe in recent years, which is why the city requires every home to have a backwater valve and why flood-zone awareness comes first in a basement project.
Our 2026 estimate for a standard bathroom in Gatineau is $6,438 to $15,660: tiled shower, semi-custom vanity, new fan and lighting. Fixtures replaced in place start near $4,509; a full redesign with curbless shower and heated floor reaches $25,056.
Our Ottawa estimate is shown just above for comparison. Two things differ once the quote is in: tax, 14.975 % GST + QST in Gatineau against 13 % HST in Ottawa, and licensing, since a contractor working in Gatineau must hold an RBQ licence, which an Ontario contractor may not have.
Usually not under $26,000 of work on an existing building, unless the foundation, the structure or interior walls are involved; above that a building permit applies. The URBAIN assistant on gatineau.ca gives the answer for your address, and the city commits to no processing time.
Labour does not, the house does. Older Hull and Aylmer homes are likelier to hide cast-iron drains and undersized rooms behind the wall; newer Plateau or Buckingham houses rarely surprise a plumber. Ask for a contingency line in the quote for a pre-1960 house.
Only with an RBQ licence: Québec requires it of any contractor doing renovation work for a client, whatever the amount. Many contractors on the Ottawa side hold one; check the number in the RBQ register.
