| Roof Vent Installation | $350–$950 | Includes attic ductwork and roof vent cap; more effective for ventilation. |

3. Factors Influencing Cost

• Bathroom Size and CFM Needs
• Choose a fan based on cubic feet per minute (CFM).
• Rule of thumb: 1 CFM per square foot of bathroom area.
• Example: 100 sq. ft. bathroom needs a 100 CFM fan.

| CFM Rating | Bathroom Size (sq. ft.) | Fan Cost Range |
|--------------------|----------------------------|---------------------|
| 80 or less | 40–80 | $20–$250 |
| 100–150 | 100–150 | $55–$400 |
| 150+ | 150+ | $100–$500+ |

• Features and Noise Level
• Fans with additional features (lights, heaters, sensors) or low-noise ratings (less than 1 sone) cost more.

| Sones (Noise Level) | Cost Range | Notes |
|------------------------|----------------|--------------------------------------------------------|
| <1 | $70–$350+ | Quietest; best for noise-sensitive areas. |
| 2 | $20–$90 | Moderate noise; standard for most bathrooms. |

• Electrical and Permits
• Electrician: $50–$100/hour.
• Permits: HVAC ($250–$400), Electrical ($10–$500), Roofing ($70–$250).

4. Additional Costs to Consider

• Fan Removal and Disposal: Often included in labor, but DIYers may need to recycle the old fan.
• Ductwork and Venting:
• Essential for new installations; costs depend on wall vs. roof venting.
• Wall vents: $250–$800.
• Roof vents: $350–$950.

5. Tips to Save Money

• Replace Instead of Install: Replacing an existing fan is much cheaper than a new installation.
• Choose Essential Features: Focus on needed features like humidity sensors if on a budget.
• Bundle Services: Combine fan installation with other bathroom upgrades to reduce labor costs.
• Get Multiple Quotes: Compare estimates from local professionals.

Proper bathroom fan installation ensures effective ventilation, reducing mold and moisture buildup while improving air quality.
