What to Change: Bathroom Ventilation Remodel

What to Change: Bathroom Ventilation RemodelIf you’re considering making bathroom renovations, there’s no time like now to think about installing/upgrading adequate bathroom ventilation. It’s a fact that bathrooms are a major source of moisture and odors that don’t stay in the bathroom. Steamy humidity produced by bathing degrades building materials and promotes mold growth. Water vapor also migrates out of the bathroom and throughout the house.

Bathroom renovations provide a great opportunity to clear the air by installing a ventilation fan or upgrading an existing unit.

How much ventilation do you need?

Most experts recommend a fan with 1 cfm (cubic feet per minute) of ventilation capacity per each square foot of bathroom floor space. Therefore, a 50 square foot bathroom needs a fan rated for 50 cfm. By the way, more is not better. Installing an oversized bathroom fan draws out excessive air volume, depressurizing the house and causing unconditioned outdoor air to infiltrate through cracks and gaps in the structure.

Where should it exhaust?

Exhausting bathroom fans into the attic space only relocates issues such as deterioration due to moisture as well as toxic mold growth up there. A bathroom vent fan should utilize a dedicated duct that extends all the way to the roof or through an exterior wall and exhausts directly into outdoor air.

What about options?

Bathroom ventilation fans, like everything else, have gotten smarter and more user-friendly.

  • Motion detectors turn the fan on and off only when the bathroom’s in use to save energy. Overhead lighting incorporated in the fan—such as a low-voltage night light—is also controlled by a motion sensor.
  • Fans incorporating a humidity sensor activate only when moisture in the air reaches preset levels.
  • Heat-exchange vent fans replace vented air with an equal volume of outdoor air to prevent depressurization while keeping the bathroom environment fresh. To maintain temperature control in winter, a heat exchanger in the unit transfers warmth from outgoing air to cold incoming air.
