Bathroom Exhaust Fan & Ventilation Renovation Vancouver 2025
Bathroom Ventilation in Vancouver Homes
Proper bathroom ventilation is critical in Vancouver’s humid climate. Inadequate ventilation causes mould, paint peeling, and structural damage. Most older Vancouver homes have under-powered or poorly installed exhaust systems.
Exhaust Fan Sizing Guide
BC Building Code requires exhaust fans in all bathrooms without operable windows. Size by CFM:
- Small bathroom (under 50 sq ft): 50 CFM minimum
- Standard bathroom (50–100 sq ft): 80–110 CFM
- Master ensuite (100+ sq ft): 110–150 CFM
- Oversized/spa bathroom: 200+ CFM
Exhaust Fan Installation Cost
| Scope | Cost Range |
|---|---|
| Replace existing fan (same location) | $250–$500 |
| New fan (new circuit needed) | $600–$1,200 |
| Fan with humidity sensor/timer | $400–$900 |
| Inline fan for multiple bathrooms | $800–$2,000 |
| Heat recovery ventilator (HRV) | $3,000–$7,000 |
Why HRVs Make Sense in New Vancouver Renovations
BC Building Code now requires Heat Recovery Ventilators (HRVs) in all new construction and major renovations. HRVs exhaust stale indoor air while recovering 70–80% of heat — solving both ventilation and energy efficiency in one system.
