How to Install a Quiet Bathroom Exhaust Fan

Installing an ultra-quiet fan and replacing the existing fan may seem daunting, but it is a relatively quick experience — if you know what you’re doing.

We go over the important steps when it comes to installing a new fan below:

Step 1: Pick Your New Replacement Fan

When replacing your bathroom exhaust fan, it’s important to look at certain dimensions, such as your fan’s length, width, and height.

If your new ceiling fan will be a different size, it’s best to compare its CFM (cubic feet per minute) Rating to the machine’s total size (in both square and cubic feet).

FUN FACT: CFM is the measure of how much air your bath fans can process.

Ceiling fans with a CFM rating of 80 and above work best for a large or commercial bathroom.

The CFM rating is often balanced by the sone rating or how much fans produce sound.

You want your bathroom exhaust fan to be quiet yet powerful enough to push fresh air in and take bad air out.

So be 100% sure to get the right one before making a purchase!

Once the air’s escape route is confirmed, it is then time to confirm your electrical options.

Although it’s best to REUSE the previous wiring, you may also need to consider if new wiring will be needed.

Step 2: Remove Your Old Exhaust Fan

With your new quiet bathroom exhaust fan ready and waiting, it’s time to say goodbye to your old noisy bathroom fan:

  1. The first thing to do is turn off the power directly at your circuit breaker. Ensuring that there is no power running will help you focus on the task at hand.
  2. You can then pull down the fan cover and unclick the locking springs, exposing the essential pieces like the motor.
  3. Once that’s done, you can then unscrew and remove the entire motor from the bathroom fan’s housing.
  4. With the motor out of the way and without accessing the attic, you may have to saw the brackets holding the fan in place against the ceiling joists.
  5. The last step is disconnecting the wiring connections and pulling them out of the fan’s housing. This will allow you to finally remove the housing from the ceiling and clear a path for the new, very quiet bath fan.

Step 3: Install Your New Bathroom Fan

You may need to make adjustments to ensure the new fan fits in the slot.

If it is TOO SMALL, you may need to saw around your previous hole to make it wider.

On the other hand, having a hole TOO BIG will mean patching the ceiling.

Extra wood will need to be drilled onto at least one side attached to ceiling joists. This creates a tighter seal for your quiet bathroom exhaust fans to slide into.

Once you get the right slot size, follow these steps:

  1. The first item to go in will be the duct connector, which connects to the existing duct with HVAC tape to prevent air leakage.
  2. Then, you will need to remove the wiring cover and unscrew the knockout plug. These give you access to the wiring, which you will connect to the previous wiring in the ceiling.
  3. Once the wires are through the cable clamp, you’ll need to attach the house wires to the fan wires. Use the connectors to match the wire colors.
  4. You will then slide the fan assembly into the ceiling, screwing it in place.

Step 4: Test It Out

Once the grills come back on, your bathroom fan is ready for action.

With the change complete, you can now turn on the breaker and confirm that the quiet fan is working to its full capacity.

When working with just the fan, the basic steps involve simply taking out the old fan and connecting your new quiet exhaust fan in its place.

NOTE: The steps vary slightly if you have access to the attic.

Using your attic access will allow you to ensure proper venting to the outside. This will prevent condensation and molding of the attic ceiling.

However, this version requires more work and may need the hands of someone more competent in carpentry.

What to Look for in Quiet Bathroom Exhaust Fans

Each of these quiet fans delivers results in its unique way.

Deciding on which one to buy will depend on just some of these factors listed below:

1. Size

You may have the quietest bathroom exhaust fan ever, but if it cannot fit in your ceiling, it’s more trouble than it’s worth.

While it is possible to enlarge the opening, the size of your exhaust fan also affects its weight and its ability to stay above your head.

A good rule of thumb is to check for the size of your exhaust fans in square feet (i.e., getting its area – length x width) and its volume (length x width x height) in cubic feet.

A good fit will ensure no air leakage through your ducts and help you choose the fan with the right CFM, thus a good Sone rating for you!

2. Air Flow

Speaking of CFM Rating, that is the rating that refers to the airflow of quiet bathroom fans.

To put it simply, Cubic Feet Per Minute is the measure of how much the exhaust fan moves.

A higher CFM means a higher movement rate, meaning more energy efficiency and sound.

It would be best to strike a BALANCE between wanting a high CFM and a low sone rating.

But the best quiet bathroom exhaust can give you anywhere from 50 CFM (small bathrooms) to 100 CFM (large bathrooms) with only 0.3-0.5 sones worth of sound.

3. Noise Output

The yin and yang of selecting a bathroom exhaust fan are how much air it pumps out compared to how much noise it makes.

The noise output for bathroom exhaust fans is measured through its Sone rating.

Though based on people’s perceptions of sound, sones are a mainstay of sound measurement and an important factor in choosing your ideal exhaust fan.

An older model ceiling fan makes far more noise, going at around 4 sones. This is equal to the sound a TV makes.

This is what led to the rise of ultra quiet bathroom exhaust fans in the first place.

The best quiet bathroom exhaust fans cost a pretty penny more than a regular fan but are more silent than rustling leaves at less than 1 sone.

4. Distinct Features

Exhaust fan technology has come a long way in the past few years.

Your bathroom exhaust fan now comes with various fan features that suit different personal preferences:

  • Higher price exhaust fans now come with humidity sensors, allowing them to regulate bathroom temperature and keep your mirrors from fogging.
  • These models come with an indicator light to let you know they’re on.
  • Bath fans nowadays may also double as a bright LED light, having an LED light integrated into the machine. You won’t have to worry about having a separate bathroom ceiling light if you get these models.

5. The Price

Price is another important factor to consider.

An expensive bathroom exhaust fan may not be the best for all occasions, especially if your bathroom is small or outside your budget range.

On the other hand, lower-priced exhaust fans may be loud and abrasive. It is thus important to balance air output (CFM) with sound level (sones).

A quiet bathroom exhaust fan (those with 0.3 sones) goes for between $40 and $400.

Frequently Asked Questions

Still have questions or concerns about best optimizing your quiet bath fan usage?

Don’t worry; we’re here to help.

What Makes a Bathroom Fan Noisy?

There are several reasons why your fan may be noisy. The first of which is just how it was made.

Cheap models have fast motors and small turbines, which leads to more sound for less work.

These fans stay in the 4 sone range, and while they’re cheap, they tend to have low CFMs for the noise they produce.

If your ceiling fan has been with you for a while, it may be dirt and poor maintenance that’s leaving it rattled.

After all, the dirtier your fan is, the worse it performs. Cleaning it and replacing the individual parts (fan, motor, etc.) may extend your fan’s lifespan.

How Can You Make Your Bathroom Fan Quieter?

While we’re on the topic of quiet bathroom exhaust fans, let’s talk about how to make your current fans quieter than they already are for a quieter bathroom.

The best quiet bathroom exhaust is one that is installed correctly.

Proper installation ensures that the fan doesn’t rattle in its pot and ensures that each part stays in place, no matter how vigorously that fan moves.

Screw everything down tightly, and you should get a solid foundation with lesser sound.

Your other option is to clean the fan completely every few months, disassembling it and using soap, water, and a toothbrush to eliminate any nasty dirt and grime.

What Is the Difference Between a Ventilation Fan and an Exhaust Fan?

Although most people use these terms interchangeably, these two kinds of fans are quite different.

Going by the name, a ventilation fan’s job is to ventilate a given space. This means it keeps the air fresh by bringing in the fresh air and spitting out stagnant air.

Meanwhile, an exhaust fan focuses less on the freshness of the air and more on keeping it from getting dirty. Exhaust fans take in air and spit out negative particles such as smoke and dust.

The main way to tell them apart is to look at where they are used.

An exhaust fan pushes out smoke and odors and is often seen in kitchens and bathrooms.

Meanwhile, a ventilation fan keeps air pure and is used in offices and bedrooms instead.

We have a guide on soundproofing vents if that is what you’re looking for.

How Many Sones Is Considered Quiet?

The Sone rating allows us to verify how loud a certain device is.

The higher the sone count, the louder the machine is.

The lowest sone count among bathroom fans is 0.3 sones, found in the “ultra-quiet” lines of most appliance brands.

Leaves rustling in the wind are slightly higher, ensuring that your fan is the quietest bathroom fan you can get.

But, to be considered quiet, a fan merely needs to hit a sone count of 1.0 or match the silent buzz of a refrigerator.

Anything above 0.3 sones but below 1.0 is already extremely quiet, and the more quiet an exhaust fan is, the more expensive it tends to be.
