Mounting Type


Installed one of three ways, bath fans can be installed as a ceiling mount - the most common, a wall mount or the versatile ceiling/wall mount.

Humidity-Sensing Bath Fans

Humidity-sensing bath fans detect increases in moisture levels at the ceiling, where steam and humidity naturally rise. The fan turns on and off automatically to help prevent cosmetic and structural problems from excess moisture.

What Sones Tell You About Fan Noise Level

The amount of noise a fan makes is an important consideration in choosing your fan. Be sure to check the sone rating. The lower the sone rating, the quieter the fan will be. A quiet bathroom fan will be rated at about 1.5 sones or less, which is about the sound of a quiet refrigerator.

The Home Depot Has Everything You Need to Select and Install Bath Ventilation Fans & Accessories

It’s important to keep stale and humid air out of the most essential rooms in our homes. That’s why The Home Depot carries a variety of bathroom exhaust fans to fit all of your needs. When shopping for a ventilation fan you should consider the room size, sound level and light options. You can also shop for fans with features such as heaters, timers and specific décor styles.

To get started consider the size of the space you need ventilated. Once you know that you need a ventilation fan that will cover a small, medium or large range of square feet, you should determine the sound level, fan style and features you’d like to have. Remember that larger spaces will need more powerful ventilation to help filter out humid air, mold, mildew, dust, odors and chemicals from the room.

Whether you prefer a decorative fan, a bath fan with a heater or one with motion and humidity sensing technology, we have the selection to ensure you find the ventilation fan you’re looking for. With our bath fan installation guides and HVAC installation services you can be sure that your fan is installed properly the first time.

These days bathroom fans can be effective in multiple rooms, so talk to our associates if you have any questions about installing a fan in your laundry room, nursery or home gym to prevent high humidity and mold and ensure your rooms are well-ventilated.
