Where do bathroom fans vent to? This is one of the burning questions asked by most people with a high interest in bath fans. To begin with, let me admit that bathrooms are damp places that require regular airflow to keep them fresh and free from odors and smells. As you all know, a bathroom is a damp room that mostly stays in a moist, warm, and wet state due to regular bathing. To ensure that mold and dampness are controlled at all times, a bath fan must be installed to maintain the overall freshness and comfort at all times.

Why consider a bath fan?

There are many reasons why homeowners consider installing bath fans over other ventilating units. Apart from the obvious reason of eliminating odors, smells, and steams from the bathroom, these units go further to reduce the concentration of dangerous and hazardous fumes caused by most cleaning agents.

Now, unlike in the past where fans were only limited to ventilating a room, today’s bathroom exhaust fans have gone ahead to incorporate more outstanding features that make them usable in many different ways. For instance, most bathroom fans available in the market provide a more decorative appeal to the room while still providing sufficient lighting to the entire room when bathing.

In addition to that, these bathroom fans are quieter than before, making them perfect for indoor applications. When it comes to the power rating, these fans are designed in a more efficient manner, allowing them to consume less power than their latter counterparts.

Where do bathroom fans vent to?

When installing a bathroom fan, one question you must ask yourself is where the fan will vent to during operation. To achieve an efficient airflow throughout the room, always ensure that the fan vents towards the roof of the house. This is the perfect vent location for each ventilation unit because of the vast air circulation at the top area. However, depending on the design of the bathroom fan, you’ll find that there are different ways through which a technician can install the ventilation unit. Now, in this section, we will highlight the different bath fan options and see how each one of them is installed.

Through the wall

The first bath fan option is the wall-mounted type of fan. This type of fan is usually installed directed towards the wall either in the interior or exterior wall. This type of fan installation is not very common as it’s only applicable to bathrooms with cathedral type ceiling (those without any attic spacing above) or where the ceiling doesn’t have any additional space left due to the large skylights.

In such a situation, you’ll need to vent the exhaust fan through the wall to the outside. Depending on the location of the bath fan, the ductwork may either be short or extensive as you’ll have to pay attention to every detail to avoid any leakage in the future.

Sometimes you may consider the ductwork to go through the exterior wall. In such a case, you only need to vent the fan directly from the bathroom to the outside wall. This technique is simple and doesn’t require you to do much of the ductwork

Through the roof

This ventilation method is mostly usable in ceiling mounted bath fans. These types of fans are the most common in most bathrooms and they involve installing the fans directly on the ceiling of the room. Such fans are suspended in an upside down position allowing them to remove moisture, odors and steam easily through a suction technique. When air is suctioned from the bathroom, it’s pulled through the ductwork (installed in the attic space) to the roof of the house while still allowing fresh air to get through.

For this method to be accomplished, a hole must be cut on the roof of the house for a vent hood to be installed. This method is very critical and must be accomplished by a professional to ensure that the roof doesn’t leak.

Final thoughts

Having highlighted the various methods of installing a bath fan, I believe that you now understand where bathroom fans vent to. Although these methods are all effective when it comes to ventilating your bathroom, professionals prefer the wall mount method over the ceiling option due to the latter’s ability to keep a house free from leakage incase of rain. With that being said, I believe that you’re now fully informed on how bath fans vent and the different methods of installing the ductwork.
