How to Vent a Bathroom Without a Window

How to Vent a Bathroom Without a Window

Be it a second-floor or upstairs bathroom, many bathrooms don’t have a window. Why don’t many bathrooms have windows? The primary reason is that there are cheaper alternatives to ventilate the room. Installing a window costs around $6,000, which drives up the price of construction. Further, homeowners want privacy in their bathroom, which is hard to get if you have a bathroom window facing your neighbor’s kitchen.

Learn How to Vent a Bathroom Without a Window Quickly

While bathroom windows aren’t as standard in new construction, you will find them in older houses. It’s very common to have bathroom windows in older homes because they were constructed without central air conditioning. Having a window in the bathroom was a great way to cool down the house. Also, older homes often have bathrooms that share a wall with the exterior of the house. On the other hand, newer homes have many bathrooms with interior walls not shared without the outside.

Install an Exhaust Fan

Install an Exhaust Fan

Inarguably one of the most effective ways to vent a bathroom without a window is to stall an exhaust fan. An exhaust fan essentially suctions out the moisture and expels it through the home’s ductwork. Not only does an exhaust fan help get rid of moisture, but it also gets rid of unpleasant smells. To turn on the exhaust fan, all you do is flip the switch next to the light switch.

How Much Does an Exhaust Fan Cost?

The average exhaust fan costs around $100 to $550, depending on the brand and the quality. It can also cost around $100 If you pay someone to install or replace an exhaust fan for you.

Can I Install an Exhaust Fan on My Own?

Yes, you can install an exhaust fan on your own. However, you will need some tools, including a drill. If you’re not handy or don’t have the tools, it’s best to hire a professional to install it for you.

Where Do You Buy an Exhaust Fan?

You can buy an exhaust fan on Amazon, eBay, and various home improvement stores, including Lowe’s and the Home Depot.

Purchase a Moisture Absorber

Purchase a Moisture Absorber

Most homeowners don’t want a moisture absorber hanging in their bathroom 24/7, but it is a very cheap way to get rid of moisture and ventilate the space. So, what exactly is a moisture absorber? Most moisture absorbers have several ounces of crystals that trap moisture. If you’re on the hunt for a bathroom moisture absorber, it’s a good idea to buy one that you can hang.

How Long Does a Moisture Absorber Last?

Depending on the brand, a typical moisture absorber will last a couple of weeks. Fortunately, most brands sell their product in quantities of three or four.

How Much Does a Moisture Absorber Cost?

Moisture absorbers are cheap, but they are often disposable products. You can easily find moisture absorber products on Amazon and at large superstores for around $10.

Wipe up Extra Moisture with a Towel

Wipe up Extra Moisture with a Towel

If you’re wondering how to vent a bathroom without a window, you can do so with a towel. It doesn’t need to be a unique towel, but one made of cotton works best. You can hang the towel inside the bathroom on the towel rack to absorb moisture while you’re in the bath or shower. You can also hang towels on the door outside the bathroom. It’s best to have a few towels because you’ll want to use one to wipe up built-up moisture on the countertop, toilet, and other surfaces. While it’s probably not the best long-term solution, using a towel can do the job.

How Often Should You Replace a Towel?

The answer to this question depends on how often you shower. If you only shower once a day, there might be enough time in between for the towel to dry. If that’s the case, you should change the towel every couple of days. If you shower multiple times a day, you will want to use a new towel each time. Understandably, you don’t want to wash a towel after each use, especially if you’re hanging it from your towel rack or door. Using a wet towel can cause even more humidity.

Install a Ceiling Fan in the Bathroom

Install a Ceiling Fan in the Bathroom

Although it might sound a bit odd at first, installing a ceiling fan can help with the adverse effects of bathroom moisture. The fan will keep the moisture moving, keeping it from sticking to the walls. However, there are two things you need to consider. First, you need to make sure the ceiling fan will fit in your bathroom. The bathroom would need to be rather large, such as a master bath. Secondly, you should consider installing an exhaust fan before a ceiling fan. A ceiling fan should be your fallback plan if you don’t have the proper ductwork for an exhaust fan.

Buy a Dehumidifier

Buy a Dehumidifier

Dehumidifiers are a great way to keep mold and mildew from calling your bathroom home. Just as they do in your bedroom, dehumidifiers will remove moisture and bad smells in your bathroom. You can mount various dehumidifiers to your wall or ceiling, but be cautious – you don’t want to install a dehumidifier too close to water. You may consider buying a mini dehumidifier, depending on the size of your bathroom.

How Much Does a Dehumidifier Cost?

Dehumidifiers are very affordable, and you don’t need a super fancy one for a bathroom. On average, you can expect to pay anywhere from $60 to $270 for a dehumidifier (less for a mini one).

Use a Battery-Operated Fan

Use a Battery-Operated Fan

Most bathrooms don’t have enough space for a ceiling-mounted fan. As an alternative, you can buy a battery-operated fan. Why a battery-operated fan vs. a plug-in fan? Having cords in your bathroom can pose a considerable risk. That’s why it’s best to use a battery-operated fan. Like a ceiling fan, these small devices keep moisture from stagnating and sticking from the wall. While they don’t magically rid of humidity, battery-operated fans prevent mold and mildew. They can keep unpleasant smells from lingering in the bathroom.

How Much Does a Battery-Operated Fan Cost?

A battery-operated fan is much more affordable than a ceiling fan. You can expect to pay anywhere from $10 to $45, depending on the size and the brand. You can check out some battery operated fans on Amazon by clicking here. 

Where Should You Place a Battery-Operated Fan in Your Bathroom?

It’s best to place a fan near areas of high moisture. However, don’t place the fan too close to the shower, toilet, or sink. You could set the fan on the bathroom counter and point it towards the shower, for example.

Open the Bathroom Door

Open the Bathroom Door

Have you ever gotten out of your shower to see your mirror covered in fog? You likely opened the door, and the fog was gone in a matter of minutes. Opening the bathroom door is probably the most obvious and most efficient way to ventilate a bathroom. If you have no other way to ventilate your bathroom, you should shower with the door open. When you open the door, cold air comes into the room and helps to close the convection cycle. If you can’t shower with the door open, there’s still the chance that mold and mildew could accumulate if you have no other way to vent the bathroom.

Open the Doors in the Rooms Next to the Bathroom

The second-best alternative to opening the bathroom door is to open the doors to nearby rooms. You might be wondering, “how will these doors help vent my bathroom?” The cold air coming into the other rooms can make its way underneath your bathroom door and dry up moisture. Opening multiple doors is also an excellent way to dehumidify your bathroom quicker once you already have the bathroom door open.

Should You Open the Door to the Outside of Your House?

In most cases, it’s a good idea to open the door to the outside of your house to help vent your bathroom. However, if you live in a humid environment, such as Florida, it’s not the best plan of attack. Opening your home’s front door could be counterintuitive if it’s sweltering outside and could cause your bathroom to steam up more.

Use a Hair Dryer

Use a Hair Dryer

A hairdryer can slightly help you vent a bathroom, but it shouldn’t be your first option. The air from a hairdryer will help move the moisture around and keep it from sticking to the walls. Of course, it will also dry water sitting on other surfaces, helping to prevent the growth of mildew and mold. Only use a hairdryer for a few minutes if you’re trying to dry your bathroom. And, most importantly, don’t leave the hairdryer unattended.

Remove Unneeded Furniture from Your Bathroom

Remove Unneeded Furniture from Your Bathroom

A bathroom cluttered with furniture is a recipe for disaster. You should only keep the essentials inside your bathroom. Certain types of furniture, such as couches, can accumulate moisture and make the bathroom damper. Subsequently, damp furniture can lead to mold, mildew, and bad smells. Even if you have a vent system, such as an exhaust fan, it can take longer to vent your bathroom if you have lots of furniture.

Can Rugs Make It More Difficult to Vent Your Bathroom?

Yes, a bathroom rug or mat can make it more difficult to vent the room. Certain materials will absorb moisture, making the rugs not only damp but also unsanitary.

What Happens if You Don’t Vent a Bathroom?

If you don’t vent your bathroom, you could end up with various headache-inducing problems. There are three significant issues that can arise when you don’t vent your bathroom: damage to surfaces, mold, and mildew. Not only are these issues costly to fix, but they can also cause health issues.

Damage to Surfaces

The most common type of surface damage caused by moisture and condensation is rust. Under humidity, metals corrode at an exceptionally high rate. You’ll end up having to replace your faucet, showerhead, and fixtures if you don’t vent your bathroom correctly.

Mold

Mold loves moist spaces and can take over your bathroom if you don’t have a way to get rid of moisture and condensation. Various types of molds, including black mold, can start to grow. Black mold can cause humans to cough and sneeze. In severe cases, black mold can also trigger fatigue, headaches, and rashes.

Mildew

Mildew, a type of fungus, can also grow in your bathroom if you don’t vent it properly. You might be wondering, what’s the difference between mold and mildew? Mildew is more of a general term that includes mold and other types of fungi.  Some types of mildew emit mycotoxins which cause side effects similar to those of mold.

What’s the Best Way to Prevent Corrosion in Bathroom?

Corrosion is a natural process that you can’t prevent, but you can delay it. The best way to avoid corrosion is to wipe down wet surfaces after using them. For example, wipe down your shower after each use. You should also frequently wipe your faucet and sink.
