How To Dehumidify a Bathroom? Easy Ways!

The best way to dehumidify a bathroom is to install a whole-house humidistat. A whole-house humidistat automatically controls humidity levels in the house and operates on both manual and automatic settings.

A whole-house humidistat has sensors in the basement, crawlspace, subflooring, and roofing tiles to detect moisture levels in the home. 

So if one of these four sensors detects moisture, it will automatically adjust humidity levels in the home via an external air vent located on a soffit or gable end of your house that feeds outdoor air into your conditioned living space.

In this article I will explain some best methods to dehumidify a bathroom. So lets get started!

How to Dehumidify a Bathroom?

You can use a whole-house humidistat that will help dehumidify the Bathroom.

The benefits of installing an automatic humidity control device are that you don’t have to do anything, and the unit will save you money by reducing your energy bill.

However, the downside is that it could be costly to install and will not provide immediate relief from excessive moisture levels in your home.

Cost of Installing a Humidistat?

Installing an automatic humidity control device can cost between several hundred dollars to a couple of thousand dollars, depending on the size of your house.

Installing a whole-house humidistat requires an HVAC contractor who can determine how much it will cost to install an automatic humidity control device.

Also, annual energy savings are possible when installing a whole-house humidistat by ensuring that your air ducts are insulated. 

If your ducts aren’t insulated, or you live in a climate where freezing temperatures are common, ensure the external air vent is located above the ground and covered with insulation. Another option would be to install a dehumidifier in your Bathroom.

How to Choose a Dehumidifier for Bathroom Without Vent?

The most important thing to consider when shopping for a dehumidifier is the size of the appliance and its features.

A machine with an auto shut-off, an automatic restart, timer settings, and exhaust capability will suit your needs if you have no ventilation in place

It’s also important not to let water sit in the reservoir overnight because this can lead to mold growth.

Continuous draining can be achieved by using a sink or hose outlet and an automatic restart function that turns on after a power outage.

Dehumidifiers are made for use in large spaces, so if you have a compact bathroom or living space, you may find a dehumidifier too large.

Small dehumidifiers are also less effective for large spaces because the air exchange rate is higher. 

You can measure humidity levels with a hygrometer or by sprinkling salt on the floor and watching how much water forms on it over time.

Finally, you should consider whether your budget can accommodate high-end models with features like built-in fans and automatic shut-offs. Prices range from $200 to well over $1,000, depending on the size of the unit and its features. 

If you have pets, go for a dehumidifier with an auto-dry system. If not, be sure to dry thoroughly after each shower to avoid mold issues.

You may need to take a few steps back before choosing the best location for your Dehumidifier because choosing the wrong model would be counterproductive.

There are three sizes of stand-alone dehumidifiers: 30 pints, 50 pints, and 70 pints or larger. 

You must choose a dehumidifier with a capacity of 50 pints or more if you plan to use it in a room larger than 1000 square feet. The improper model will result in a worse coverage area and a longer dehumidifying time. Find out more information about dehumidifiers for various room sizes here.

How Long Does it Take to Dehumidify a Bathroom?

The answer to this question depends on a few specific situations you are facing:

  • The room’s size in general
  • How big a dehumidifier do you get to deal with the issue

Let’s explore them in greater detail below.

a- The Dehumidifier’s size

Imagine purchasing a dehumidifier that is too small. In that instance, drying out the room might take longer than expected. On the other end of the spectrum, choosing one too big may solve the original issue extremely effectively. Still, it won’t be useful moving forward for any more issues.

b- It is based on Size & Capacity

All dehumidifiers have a maximum amount of moisture they can remove from the air and come in various sizes. The unit’s removable tank is used to hold the extra water that was discharged from the viewpoint.

How to Absorb Humidity in the Bathroom?

Without a dehumidifier, there are several methods you may use to dry up a space using cheap, readily available items, which include Baking soda, rock salt, charcoal briquettes, silica gel, and Boston Fern. 

1- Baking Soda 

Something as simple as baking soda can somewhat reduce the humidity in a space. Of course, it doesn’t work as well as a dehumidifier purchased from a store.

However, it can still absorb moisture and keep the area free of the musty odor caused by moisture and mold growth. 

To get rid of mold stains and patches, sprinkle some baking soda on the area. The baking soda will keep the area dry and odor-free.

After a lengthy, warm bath, are you having issues with excessive humidity levels in the shower? Do not panic; the baking soda can save you.

All you need is a small bowl filled with baking soda left in a dry bathroom. This will not only stop moisture and humidity from spreading around the Bathroom but also stop the formation of fungi. This is a great technique to dry out a space without using a dehumidifier.

2- Rock Salt

Yet another easy but efficient method for organically dehumidifying a space: rock salt!

Over time, this has been utilized as a natural dehumidifier to regulate moisture and humidity. Just like you would anticipate from a dehumidifier, rock salt can absorb moisture and odors from a moist atmosphere. 

However, removing moisture from the air and surroundings is unquestionably useful in most instances. You can create your rock salt dehumidifier home with items you already have.

All you need 

  • 2 Container 
  • Sharp object to drilling holes 
  • Rock salt 

You have to poke a few holes in one of the buckets’ sides and set it on top of the other. Next, fill the bucket with rock salt, then leave it in the humidification-controlling room. 

As the rock salt absorbs moisture from the air, it will gather at the bottom of the bucket. As often as possible, discard this water, and keep replenishing the bucket with more rock salt. This simple approach works well and is economical.

3- Charcoal Briquettes

Briquettes made of charcoal are the next item on the list of DIY dehumidifiers. This is another well-known technique for naturally dehumidifying a space.

For quickly and effectively removing moisture from the air, use charcoal. You may easily solve the problem of high humidity in any room in your home by using charcoal briquettes.

All you need 

  • Charcoal Briquettes 
  • Can or tin with lid 
  • Screwdriver 

Create holes in the can’s sides and place the charcoal briquettes inside.

Next, place the can in the space where the air has to be dried out and cover it with the lid. This is a fantastic option for DIY dehumidifiers for the kitchen, Bathroom, closet, etc.

Charcoal can be a great air dryer for tiny places in your home, albeit it cannot take the place of real dehumidifiers.

However, keep in mind that the charcoal in the container will no longer be able to effectively dry the air after a few months.

2- Silica Gel

Another clever method for removing humidity from space without the use of dehumidifiers is silica gel.

It can simply be thrown into any location that requires the removal of airborne water.

You can use silica gel pellets by storing them in an accessible bowl or container inside cupboards, closets, or other enclosed spaces.

3- Boston Fern

There aren’t many houseplants that can control room humidity without a dehumidifier. One of them is the Boston fern, a widespread plant that does well in damp environments.

This low-maintenance plant can be kept anywhere in your home, including the kitchen, living room, bathrooms, and dining tables. 

It thrives in moisture and only has to be watered twice a week because it can get all the nutrition it needs from the moisture in the air. The Boston fern is an excellent natural remedy for dealing with dampness.


Why is my Bathroom so humid all the time?

Because of the moisture our showers produce, our bathrooms are frequently more humid than other rooms in the house. Hot showers may be soothing but can also have unintended negative effects. Humidity levels in your Bathroom will rise as more moisture gathers there.

An organic dehumidifier is what?

Rock salt is the DIY Dehumidifier that performs best and is the most often used. Rock salt is an excellent choice as a dehumidifier since it naturally absorbs moisture from the air.

What can effectively absorb moisture?

Rock salt might be the solution if you want to solve your moisture issue on a budget. Rock salt collects moisture from the air because it is hygroscopic. Start with a 50-pound bag of sodium chloride to create a rock salt dehumidifier if your goal is to eliminate the humidity in a damp basement.

Should I use the Dehumidifier while taking a shower?

Installing a fan with an exterior vent is one of the greatest suggestions for preventing bathroom wetness.

To help circulate the air and get rid of the moisture that has leaked during your long, hot shower, run a bathroom dehumidifier both during and for 15-20 minutes.

Does using a bathroom fan lessen humidity?

Bathroom exhaust fans will aid in humidity control and eliminate water vapor from your walls and mirrors.

What alternative exists to a dehumidifier?

Rock salt, DampRid, Dri-Z-Air, baking soda, and silica gel desiccants are a few of the items you can utilize. Other things like a fan, air conditioner, and space heater are also options.

In addition, excessive moisture can be eliminated by venting your home, removing indoor plants, cooking outdoors, and taking shorter showers.
