In Montreal, Quebec, a standard-quality bathroom renovation typically costs between $6,882 and $16,740 in 2026 — prices are below the Canadian average, with a local cost index of 93%. 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 Laval: $6,586 – $16,020 at standard quality, about 4 % cheaper than Montreal on our cost index.
Most Montréal bathrooms sit in plexes, and the plex sets the price: the drain stack that serves every floor runs through the wall you are about to open, and on a pre-war building it is often cast iron that has to be replaced while the wall is open. Ask for that line in the quote. In a divided co-ownership, anything that touches a shared wall or the building's plumbing goes through the syndicate before work starts. Permits are a borough matter; the fee schedule is citywide.

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.
Montréal's renovation market is a plex market: duplexes and triplexes with shared walls, common elements and a syndicate when the building is a divided co-ownership. A large, bilingual pool of RBQ-licensed contractors serves it, and the cost index sits between Québec City and Toronto.
Cold winters, hot humid summers and repeated freeze-thaw: insulation, air sealing and materials rated for it matter more than in milder cities. Snow load is a design factor for roofs, and ice dams are common on older homes without proper attic ventilation.
In 2026, a bathroom renovation in Montreal costs between $4,818 (budget) and $26,784 (premium). The average standard cost ranges from $6,882 to $16,740.
For Montreal, the ideal window is late spring through early fall (May to September) for any work touching the building envelope. Book your contractor 4 to 8 weeks ahead during peak season — last-minute scheduling typically pushes the start date much further than an off-season project would suggest.
Demolition, painting, baseboards, and small fixtures are jobs many homeowners take on themselves. Avoid touching plumbing, electrical, or gas without permits and inspection — most municipalities prohibit it, and bad workmanship can void your home insurance. On a typical Montreal project, DIY can shave 10–20% off the total.
A bathroom renovation typically returns 60–70% at resale in Canada. The exact figure depends on material choices, the current state of the Montreal housing market, and quality of execution.
A standard bathroom renovation typically takes 2 to 5 weeks. Premium projects or surprises (structural issues, delivery delays) can extend it. Always get a written schedule from your contractor before signing.
