Some bathroom renovation tasks Ontario homeowners can safely DIY; others require professional installation for safety, code compliance, and longevity. This guide breaks down each.
DIY-Safe Bathroom Renovation Tasks
- Cosmetic refresh (paint, hardware swap).
- Faucet replacement (existing supply lines).
- Vanity swap (like-for-like).
Tasks That Require Professional
- Tile install in shower (waterproofing skill required).
- Plumbing relocation.
- Electrical (new circuits, GFCI changes).
- Schluter waterproofing membrane install.
- Permits and ESA coordination.
Why Professional Matters
Improper waterproofing leads to $8,000–$25,000 substrate rot remediation within 2–5 years. Schluter Kerdi installation requires skill. Professional install is non-negotiable for shower work.
