There are a lot of benefits that come with installing a bathroom exhaust fan. For one, a bathroom exhaust fan can surely eliminate fogged-up windows. You can also say goodbye to stale odours that are common in bathrooms without proper ventilation. Most importantly of all, a bathroom exhaust fan will prevent problems related to moisture such as mildew and mould build-up.
Installing a bathroom exhaust fan sounds simple enough, but you can’t just pick a spot inside your bathroom at random and install the fan. There are a number of things that we need to consider before picking up our power drill and saw and making a hole for the bathroom exhaust fan. Here are some of the things to consider when installing a bathroom exhaust fan.
Pick the dampest spot
When picking out a spot for the bathroom exhaust fan, always pick the part of the bathroom that is most commonly exposed to a lot of moisture. More often than not, this spot would be the area over the shower or bathtub.
Shortest and most direct route for ventilation piping
Another factor that needs to be considered when choosing a location for a bathroom exhaust fan is how close or how direct it would be to the roof vent. With the said location, the ventilation piping or flexible hose won’t have to travel far or take a roundabout route towards the roof vent.
When picking a spot for a bathroom exhaust fan, make sure you avoid any obstructions as well as parts of the roof that could be considered as trouble areas. Among these obstructions you need to steer clear of are skylights, chimneys, heating vents or roof valleys.
Tips for installing a bathroom exhaust fan
When you’ve finally decided on the location of your new bathroom exhaust fan, it’s time to break out the tools and start working. Before anything else, you will need to drill a reference hole using a small drill bit. This reference hole is the one you’ll use to determine the exact position of the bathroom exhaust fan. Once you’ve drilled this hole, look above the ceiling and see if it misses electrical wires, ducting and joists. If it does, then the location is a favorable one for your bathroom exhaust fan.
Take measurements of the bathroom exhaust fan housing and its intake port to determine what size hole you need to cut in the ceiling. Make sure that your measurements are accurate before cutting your ceiling open. A reference hole can be easy to patch up, but a wrongly-measured and cut hole the size of a bathroom exhaust fan is one major booboo.
Once the hole is cut, install the bathroom exhaust fan as well as the piping or flexible ducting. Afterwards, make the connections to the fan and roof vent. Applying silicone caulk around the connections should seal it, effectively eliminating any moisture leaks into your attic.
One last thing about bathroom exhaust fans: If you’re going to install one, make sure that it is of superior quality. Go for well-known brands to ensure better reliability and durability.
