Answer: Yes, always
Explanation: Yes. A ducted bathroom exhaust fan should vent directly to the outdoors through a properly installed roof or wall vent. It should not terminate in an attic, crawl space, wall cavity, or garage, because the moisture being removed from the bathroom can damage insulation, framing, and other building materials. A properly vented fan helps control humidity, condensation, mold growth, and moisture-related damage.

Answer: Yes, always
Explanation: A bathroom fan absolutely should vent to the outside, and in most places, it's required by building code.
Venting into an attic, crawl space, or wall cavity is a big no-no. All that warm, moist air can cause mold, mildew, wood rot, and even damage insulation or your roof structure over time.A proper installation runs a duct from the fan to a vent cap on the roof, wall, or soffit, depending on the layout. |
