When it comes to choosing a bathroom exhaust fan, there are a lot of factors to consider. Do you need a light? A heater? What style will best fit your bathroom décor?

And, of course, you’ll want to find a model that fits your budget. In this blog post, we’ll walk you through everything you need to know to choose the right bathroom exhaust fan with light & heater for your home.

Types of Bathroom Exhaust Fans with Light & Heater

There are three main types of bathroom exhaust fans with light & heater on the market today:

  • Integrated units – These models have the light and heater built into the fan itself. They’re a great option if you’re looking for a space-saving design.
  • Separate units – As the name implies, these models have the light and heater built into separate units. This gives you more flexibility when it comes to installation, but it can also be more expensive.
  • Combination units – These models include a light and a heater, but they can be used independently of each other. This is a great option if you’re not sure if you need both a light and a heater in your bathroom or if you want the flexibility to use them separately.


The size of your bathroom will play a big role in determining which size exhaust fan you need. Generally speaking, the larger the room, the larger the fan you’ll need. But there are other factors to consider as well, such as the height of your ceiling and whether or not the room has any windows.

How to Choose the Right Size Bathroom Exhaust Fan with Light & Heater for Your Home

To get an estimate of how much airflow you need, start by multiplying the length and width of your bathroom (in feet) to get the square footage. Then, multiply that number by 0.3 to get an estimate of how many cubic feet per minute (CFM) of airflow you need. For example, if your bathroom is 10’x10′, that’s 100 square feet. Multiply that by 0.3 and you get 30 CFM.

Once you know how much airflow you need, consult this CFM chart to find out what size fan you need:

- 25-35 CFM: small bathroom OR windowed bathroom up to 100 sq ft    - 110-130 CFM: very large bathroom OR windowless bathroom up to 225 sq ft   - 36-60 CFM: mid-sized bathroom OR windowed bathroom up to 140 sq ft    - 131-200 CFM: extremely large room OR heavily used areas like gyms 

Whether you’re looking for something sleek and modern or traditional and timeless, there’s sure to be a bathroom exhaust fan with light & heater on the market that’s perfect for your home.

And now that you know how to choose the right size and type for your needs, finding that perfect fit is easier than ever!
