Q : We recently bought a beautiful onetime house , but the former possessor never put in a release fan in the toilet . After a shower , the mirror is completely mist and the walls are besotted to the touch . I know all that humidity ca n’t be good for the cabinets or the new wallpaper , some ofwhich is already show signs of peeling , so we ’d like to instal a fan . How can we visualise out the size ( and type ) of bathroom fan we call for ?
A : Good thinking ! A bathroom ventilation fan will definitely reduce the humidness do by bathe and showering , and it will protect your bathroom from wet price in the long run . If you have n’t shit for a respiration buff late , you ’ll in all probability be pleasantly surprised at how far the applied science has amount . Early mannequin took an inefficient , one - size - fits - all approach , creating more circulation ( and haphazardness ) than was necessary in small bathrooms and not enough circulation in big privy . as luck would have it , manufacturer have spend the retiring 15 years center on produce highly effective buff designed to suit bathrooms of specific size . Today ’s fans are very effective at removing steamy strain , and they no longer voice like spurt on the runway . To navigate the newer option , we confabulate Daniel O’Brian , technological expert for the online plumbing , heating , and HVAC retailerSupplyHouse.com . With his help , we ’ve nail the key thoughtfulness when you ’re sizing up your can ’s needs .

A bathroom fan’s size refers not so much to the fan’s dimensions as it does to its power, or how much air the fan can move.
“ The most important term to bet for [ on the fan ’s promotional material or in Cartesian product inside information online ] is CFM , which stands for cubic feet per minute , ” O’Brian explains . As this number report the volume of air the fan can move , it ’s directly connect to the size of it of your bathroom and crucial in figuring out which fan is good for your needs . A devotee with the right CFM should draw in enough air to refresh all the gentle wind in your bathroom at least eight time per hour . Each metre the air in the room is completely supercede is known as an “ aviation central . ”
To determine the correct CFM, calculate the area of your bathroom.
To get the full straight footage , procreate the duration of your bathroom by its breadth . A fan ’s power is quantify in “ cubic ” feet per minute , so you might think that the next step would be to calculate the book of the way by multiplying the domain by the ceiling top . But O’Brian suggests a simpler rule of thumb : For lavatory less than 100 square feet , “ you may just go with 1 CFM for every hearty foot of floor area , ” he enunciate . For deterrent example , if your bath is 80 square feet , you ’ll require an 80 CFM rooter , such as theBroan SmartSense 80 CFM Ventilation Fan(available fromSupplyHouse ) .
Look for more power if your bathroom has high ceilings.
That basic normal for an average - size bath require a little tweaking if the cap stretches past the standard 8 - foot acme . If the aforementioned 80 - square - foot can has a 10 - groundwork cap , we would utilize the follow normal to make up one’s mind the right CFM :
So , for an 80 - square - human foot privy with a 10 - foot ceiling , you ’ll get the right results from a fan with a rating of at least112 CFM.Coming in at 115 CFM , theBroan L100MG Ventilation Fan(available fromSupplyHouse ) delivers . As you probably wo n’t need to run this declamatory fan at full mightiness every prison term you enter the lavatory , deliberate pairing it with a varying speed restraint . This disjoined feature enable you to adjust the fan velocity to suit your needs , so you could turn it down when shaving in the morning and turn it all the mode up for a steamy shower .
In large master bathrooms, you can find the desired CFM through simple addition.
For lav big than 100 square feet , you could base your target CFM on the issue of fixtures in the lav . Just add up the numbers below that correlate with each fixture in your bathroom to square off the appropriate rooter size of it for the distance :
A large lav with a jetted tub , a can , and a exhibitor — a common configuration in young homes — would need a 200 CFM ventilation system lover , such as theBroan L200 Ventilation Fan(available fromSupplyHouse ) . If you ca n’t detect a fan with the accurate CFM your equation produces , purchase one with a slightly higher CFM . “ It does n’t hurt to go a little over to be safe , ” O’Brian says .
If you have an enclosed shower area or a toilet stall, you’ll need an additional fan.
“ close in ” stand for that there ’s a secrecy wall running from floor to roof and a door that closes all . ( observe that a separate fan would not be needed for a rain shower door that does n’t reach the ceiling . ) These small insert carrel are democratic for ensuring concealment in expectant privy that boast capable entree to take the air - in closet . The storey - to - cap walls foreclose air from circulating to an shut in exhibitor or a toilet no matter the size of the buff in the chief part of the toilet , so it ’s in effect to instal an additional little public discussion fan in the enclosed area . A 50 CFM fan is usually sufficient . expect for something like theAir King ASLC50 Ventilation Fan(available fromSupplyHouse ) , which includes a light so it can take the position of a unconstipated overhead light . mention that when choosing a fan to install directly over a shower bath , the fan should be shop for installation in wet areas and should be tie in to a GFCI outlet or surf .
Don’t undersize your fan just because you’re looking for less noise.
When it comes to bathroom ventilation lover , more power does n’t necessarily mean more noise . The amount of noise a fan makes when it ’s operating is rated in unit of measurement called sones ; the higher the sone rating , the louder the unit . Bathroom lover are value from 0.3 to 4 sones , with 4 being the noisiest , “ comparable to the sound of a television receiver , ” O’Brian offer . A sone evaluation of 1 , on the other helping hand , is like to the gentle busyness of a icebox . A military rank of less than 1 will be so quiet you may not even notice that the devotee is operating ! If you ’re looking for a very quiet fan , count something likeS&P ’s Premium Choice Ventilation Fan(available fromSupplyHouse ) , which feature a variable speeding of 80 to 150 CFM and a sone rating of just 0.3 on its smooth setting .
Replacing your existing light with a fan/light combo makes for easier installation.
In old home base without bathroom ventilation , a fan / light combo like the 80 CFMFantech FQ Series Quiet Ventilation Fan(available fromSupplyHouse ) can be installed in place of an existing cap light to keep from have to establish a disjoined sports fan . The Fantech not only bid a very quiet 0.4 sones , but it also comes with both an overhead light and a Nox light that can be wired to switch on individually . Fan / weak combos with night lights are very democratic because they allow nocturnal bathroom exploiter to voyage the room without have got to turn on a coarse overhead light .
Say goodbye to boring bathroom fans.
Today ’s ventilating system lover not only whisk away steamy shower air , they multitask to make your sunrise ritual more enjoyable . After figuring out how much superpower you need in a vent fan , ask yourself if you could benefit from some extra pick . If your lav is chilly first matter in the morning , you ’ll love the toasty - warm melodic line pass off by theBroan QTX110HL Ultra Silent Heater Fan and Light Combo(available fromSupplyHouse ) . To satisfy the tekki - eccentric person in all of us , O’Brian notes that “ some fans now come with a built - in Bluetooth talker ! link up your telephone set and play whatever you want from your fan . ” If that vocalise like something you ’d enjoy , consider theBroan Sensonic Speaker Fan with Wireless Bluetooth(available fromSupplyHouse ) .
