Shower Fan

But what if your bathroom has deteriorated as a result of the moisture left on the ceilings? A shower fans is the answer.

A shower fan is actually an exhaust fan. These fans help in reducing the water vapor content in your bathroom, or any room with small windows or no windows at all. The moisture from your daily shower settles on your ceiling. Once this moisture accumulates, it becomes unhealthy for us as molds and fungi grow on these wet spots. Mildew also forms at these areas of moisture when unattended; it damages the tiles and ceiling, and makes bathroom cleaning difficult.

Installing a shower fan

Installation of a shower fan call for the need of knowledge in adjusting house wirings and carpentry. If you do, the next step is to prepare. Scan the electrical map of your house for the location of electric wires. Get the tools ready: both Phillips and flat-headed screwdrivers are needed for mounting brackets inside the ventilation fan and for the fan's frame; a wire stripper so that you can remove the coatings of the house wires at the attic and the wires inside the fan; some wire nuts – these are actually included in your shower exhaust fan unit but it is best if you have some at bay – to cover unprotected wires that can cause electrical shock if you are not careful enough; an exhaust duct kit if you don't have installed vents in your bathroom; an electrical tester to make sure the placement of the wirings during installation is correct; a jab saw to cut a hole in the ceiling to place your fan; and a drill to bore a reference hole. Include a ladder if you want the ventilation fan to be placed in the ceiling or an unreachable part of the bathroom wall.

The setting up of a shower fan starts with boring a reference hole on the site where you want to install the fan. Draw a mark using a pencil; after that, drill a hole into the attic. If you want the fan to be installed at the ceiling, climb into the attic and remove any insulation at the fan's site. Measure a portion of the ceiling equal to the measure of the fan's housing. Take note of the location of pipes so that you won't be able to puncture or damage some while you set up the fan. Mark the dimensions.

Cut out the marked piece using a jab saw or a jigsaw and carefully remove the portion. In the attic, attach a duct elbow to the outlet port of the fan's side housing; aim the elbow upwards and secure. Attach cable connectors to the power outlet of the fan, preferably connect the cable connector to the wires of the bathroom switch; and then fix in metal brackets to the attic joists for additional support. Slip in a flexible duct with the elbow duct and secure using foil tape. Connect the connectors to the electric wires. Make a hole for the flexible duct on an outside wall of the house positioned on where the flexible duct will exit and then secure the duct to the hole. Install the wall cap – so that rainwater will not enter the duct and the bathroom – provided with the flexible duct at the outside, and press into the house's siding and apply some adhesive. Back inside the bathroom, remove the motor and the blades inside the housing to expose the fan's wires. Peel off a portion of the wires from both the cable and the fan, and then join wires of the same color. Cover the exposed wire joints using wire nuts. Place the fan's motor back to the installed and wired housing and screw to secure. Finally, turn the switch on and off to test the connections made. Adjust if there are some corrections.

Some guidelines on installation

Whenever a shower is being installed, a good placement of the shower fan shall be included. These fans suck the moist air out of the bathroom, so do not place them near a window. You don't want to suck the clean, inbound air out of the bathroom. Also, never install shower fan where there is maximum moisture to prevent grounding of the fan unit. To make sure that the shower fan is installed and utilized correctly, consult an electrician for tips.
