This ultimate checklist is your roadmap to a smooth and stress-free bathroom renovation in Montreal, built from the ground up by our DemoPrep team of renovation experts.
Step 1: Define Your Goals
- ✅ Is this for resale, function, or luxury? The goal will guide every decision.
- ✅ Who uses the bathroom? A family of five has different needs than a guest suite.
- ✅ Any existing issues? Water damage, poor ventilation, or outdated plumbing?
Being honest about your needs avoids overdesigning or cutting corners where it counts.
Step 2: Set a Realistic Budget
In 2025, the average bathroom renovation in Montreal ranges from $15,000 to $35,000+, depending on scope, finish, and layout changes. Plan for:
- ✅ Demolition and disposal
- ✅ Plumbing and electrical upgrades
- ✅ Tile and fixtures
- ✅ Permits (if applicable)
- ✅ Labor and materials
- ✅ Contingency fund (10–15%)
DemoPrep provides full-service quotes so there are no surprises.
Step 3: Get the Right Permits
If you’re moving plumbing, opening a wall, or touching electrical systems, you’ll likely need permits through your borough. Some common rules in Montreal:
- ✅ You don’t need a permit for cosmetic updates
- ✅ You do need a permit for major layout changes
- ✅ All electrical must be done by a master electrician

Step 4: Book a Timeline (and Expect Delays)
DemoPrep’s average bathroom renovation schedule:
- Design and material selection: 1–2 weeks
- Permits (if needed): 2–4 weeks
- Demo + rough-ins: 1 week
- Tile, fixtures, and finishing: 2–3 weeks
Material delays, inspection rescheduling, and custom orders can affect this. That’s why a buffer zone is key.
Step 5: Hire a Licensed Team
Montreal’s aging housing stock brings hidden issues. Hiring the cheapest contractor often ends with mold, structural surprises, or failed inspections. At DemoPrep, we only work with licensed and insured subcontractors, including:
- Master electricians
- Plumbing-certified teams
- Tile and finishing experts

Step 7: Don’t Forget Storage
Storage is one of the most overlooked bathroom elements in Montreal. We recommend:
- Wall-mounted vanities for floor space
- Recessed shelving or niches in showers
- Built-in medicine cabinets with hidden plugs
⚙️ Step 8: Plan Ventilation + Heating
Humidity is the enemy of a good bathroom. We install:
- ✅ Timed humidity-sensor fans
- ✅ Radiant floor heating (popular in Montreal winters)
- ✅ High-efficiency window replacements if needed
Step 9: Document Your Reno
Take before-and-after photos and keep all receipts. Why?
- Helps with resale or future insurance claims
- Tracks warranty-covered items
- Makes your contractor accountable
We provide a full renovation report to our clients at closeout.
Bonus Tips for Montreal Homeowners
- Use bilingual labels and switches if renting or selling
- Account for winter scheduling delays (demo dumpsters, delivery trucks)
- Ask about Hydro-Québec rebates for water-saving fixtures
