Bathroom Renovations in Ottawa
Planning a Bathroom Renovation
A bathroom renovation starts with the existing wet areas, ventilation, layout and the interfaces between waterproofing and finishes.

Starting condition
An older bathroom may have worn tile, fixtures or storage. The owner may want a refresh or a changed layout, but concealed substrates are not yet visible.
The problem
New tile and grout do not make a shower waterproof. Covering damaged substrate or choosing fixtures before checking space and services can create costly rework.
What to inspect
- Review leaks, staining and soft surfaces
- Inspect accessible wet-area substrate
- Check ventilation and moisture history
- Measure fixture and door clearances
- Identify plumbing and electrical changes
- Clarify permit or building requirements for proposed scope
Recommended approach
Separate cosmetic finishes from wet-area assembly work. Define a compatible waterproofing system and sound substrate where needed, coordinate qualified trades, and confirm product and approval requirements before closing walls.
Typical scope
Preparation
- Measure room and confirm fixtures and finish plan
Removal
- Remove approved old fixtures and finishes
Installation
- Build assessed substrate and wet-area system before finish coverings
Adjustment
- Fit fixtures and storage to verified clearances
Finishing
- Complete tile, paint, trim and sealant within scope
Cleanup
- Remove debris and review access and operation
Exclusions
- Hidden rot, contamination, permits and regulated trade work require explicit scope
Materials
- Approved wet-area substrate and waterproofing system
- Selected tile or wall finish
- Compatible setting and grout materials
- Fixtures and trim chosen for measured space
Work sequence
- Document layout and moisture history
- Open agreed areas and assess substrate
- Coordinate services and approvals
- Install appropriate wet-area assembly
- Finish surfaces and inspect operation
Possible complications
- Hidden water damage expands demolition
- Fixture dimensions alter layout
- Ventilation or service changes require another trade
Quality checks
- Waterproofing sequence follows selected system
- Surfaces and fixtures are secure
- Drainage and sealant details match design
- Doors and storage clear each other
- Ventilation and access remain usable
Expected result
The goal is a functional bathroom with wet-area work and finishes appropriate to the assessed conditions. Concealed findings can change the approved scope.
What changes the scope
- Extent of demolition and hidden damage
- Wet-area system
- Fixture and layout changes
- Trade coordination and selected finishes
