A ventilation system is an essential addition that makes your bathroom better than ever before. A bathroom without a fan is like a fireplace without a chimney. If the fireplace doesn’t have a chimney, then smoke is likely to spread throughout the house making you uncomfortable instead of providing you with warmth. On the other hand, a bathroom fan allows your bathroom to stay cool, aerated and highly ventilated to avoid mold and mildew buildup.
Bathroom fans are designed to suck out moisture, steam, and odors from the bathroom. If the room is left unattended for long, mold and mildew build up will be expected to take over, causing serious damage to the walls, the painting, the roof, and the tile floor. However, due to their complexity, most people may be wary of installing bathroom fans in their rooms and may prefer other methods such as buying fresheners and opening bathroom windows for precise air circulation.
Like we explained in the other articles, bathroom fans are very important when placed in the bathroom ceiling as they help in sucking out bad odors, smells, steam, and moisture. Once your bathroom is ventilated, damages caused by mold and mildew will be largely minimized leading to low costs of repair.
Before we move on, I would like to explain how fans are measured. Now, when buying a bathroom fan, there are two major factors you need to consider which include the strength of the fan (measured in CFM, and the noise rating (measured in sones) and.
CFM—which stands for Cubic Feet per Minute—is a measurement that’s used to rate the strength of a fan. On average, most fans have a CFM rating that ranges from 50 all the way to 1,000. For those who don’t have an idea on which type of fan to buy, always check one with a CFM rating of less than 200 to avoid spending much on power.
Next, we have the noise meter. Measured in sones, the noise meter ranges from 0.5 all the way to 4.0 depending on the type of fan you’ve installed. Most people may prefer installing silent motors with a noise rating of 0.5 to 2.0. However, there are some homeowners who may prefer noisier alternatives (ranging from 3.0 to 4.0 sones) as a way of providing privacy against toilet noises.
Finally, when purchasing a bathroom fan, it’s important to understand that CFM and sones are related at some point. You see, a powerful fan with a higher CFM will obviously be expected to produce more sound while a weaker fan with a lower CFM will produce less noise due to the low suction power.
Now, having said that, let’s answer this question of whether a bathroom fan can be installed in the shower. To answer this question, let me say that bathroom fans are intended to be installed in the ceiling to allow precise suction of moisture from the bathroom. When choosing the best location to install a fan, you need to consider the perfect location where the fan will accomplish its mission easily and a location where the ductwork will run efficiently.
The primary objective of a bathroom fan is to suck out as much moisture as possible from the bathroom. Therefore, a fan should be located in an area where the most moisture, steam, and odor are likely to accumulate to. In this case, areas above the shower or the bathtub will be perfect. If your bathroom only has a shower, then the fan should be installed in an area over the shower. On the other hand, if your bathroom has a shower and a bathtub or a whirlpool tub, then the fan should be installed in between the two to allow perfect suction of moisture and steam from the bathroom.
Something else you should be keen on when installing a bathroom fan is the location of any available intake air source. In this case, we’re talking about the windows and the doors. To allow fresh air movement throughout the room, ensure that the bath fan is located away (at least five to eight inches) from the window or the door.
If you have multiple bathrooms in the house, then you should consider installing independent fans in each room to allow precise air circulation. In case of a toilet, it would be better to install a noisier fan to maintain the privacy due to toilet noises. With that being said, I believe that you’re now fully informed of the best location to place a bath fan and which type of fan is the best to consider.
