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. |
