There are many possibilities for mounting bathroom ventilation fans. To replace an older unit the simplest solution may be a retrofit kit, available for most Broan and NuTone models. These kits include a new motor and grille, allowing users to improve operation while keeping their present ducting.
For new installations, ceiling fans generally go between ceiling joists. They are connected directly to venting ductwork. Inline fans can be mounted in an attic, and have the ability connect to grille housings in more than one bathroom. Wall-mount fans present another option. With the fan on an exterior wall, they connect to the grille housing located above the bathroom. SupplyHouse.com stocks bath fans from Fantech, Panasonic, and Broan-NuTone.
