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.
Montreal offers moderate renovation costs compared to Toronto and Vancouver, with a large pool of bilingual contractors. The city's distinctive triplex and duplex architecture means many renovations involve shared walls and multi-unit considerations. Quebec's Régie du bâtiment (RBQ) licensing ensures contractor quality but also means only licensed professionals can perform major work.
Montreal requires permits from the borough (arrondissement) for structural modifications, plumbing, electrical work, and exterior changes. Processing times vary by borough — the Plateau and Ville-Marie are typically slower (3–6 weeks). Quebec law requires all contractors performing work over $5,000 to hold an RBQ licence.
Montreal's extreme temperature range (-10°C in January to 27°C in July) demands high-quality insulation and materials rated for severe freeze-thaw cycles. Snow loads are a key factor for roofing projects, and ice dams are common on older homes without proper attic ventilation.
In 2026, a bathroom renovation in Montreal costs between $5,441 (budget) and $30,240 (premium). The average standard cost ranges from $7,770 to $18,900.
Montreal has a cost index of 105% relative to the Canadian national average. Prices are near the Canadian average. This index accounts for local labour costs, materials, and permit fees.
A standard bathroom renovation typically takes 2 to 5 weeks. Premium projects or unexpected issues (e.g. structural problems) can extend the timeline. Always get a detailed schedule from your contractor.
A bathroom renovation typically yields a 60–70% return on investment at resale in Canada. ROI depends on material quality, the local real estate market in Montreal, and the property's condition.
