Who Should Take Extra Care When Using A Steam Shower?

  • Pregnant women - the high temperature can cause negative birth effects on pregnant women. According to studies, heat exposure can be a factor for defects and stillbirth.
  • Men who can't easily conceive a child - prolonged exposure to heat can temporarily decrease their fertility since sperm require a cool temperature to survive. 
  • People with cardiovascular disease - heat can make the heart pump at a faster pace and eventually cause shortness of breath. 
  • Person who drinks - people who are under the euphoria of alcohol might easily fall asleep or become unconscious. They may experience symptoms of overheating, such as a headache, dizziness, and fainting. 

Cons Of A Steam Shower

A steam shower doesn't have a lot of disadvantages, and the benefits it provides outweigh the cons. If you have one in your bathroom, you might already be aware.

However, for those who are still thinking of getting one, we will talk about the cons of having a steam shower.

First, they're expensive—the steam shower itself, and the installation. You will need a plumber and an electrician.

There are a lot of key points that must be executed properly to prevent further damage. The cost of repairs will only add up to the expense.

Second, you need to have a plan. You can't just put it anywhere in the bathroom. You need to put in a spot that has enough space for the shower (and the bench inside), and the generator to produce and deliver steam.

There should also be a protected electrical outlet for it to avoid frozen pipes during winter. 

Third, it can spike up the amount of your electric bill. Although steam showers only use 1 to 2 gallons per 20 minutes of use, frequent use of this device makes the generator use more power.

Also, it can increase the level of humidity in your bathroom. This can create an opportunity for mildew and mold to grow. We do not want that, since they can be a nuisance.

What Mildew And Mold Does To Your Bathroom

Mildew, which later on becomes mold, can damage the following:

  • Walls
  • Floors
  • Porous materials in your bathroom.

Not only that, they can trigger allergies and asthma for some. Therefore, installing a vent for the steam shower helps prevent mildew and mold from growing in your bathroom. Next, we will talk about the different vents you can choose.

Vents For A Steam Shower - What Types To Choose?

The first thing to consider having is the standard exhaust fan. You can install it near the enclosure of your steam shower to suck up moisture.

Next, are the louvers. A louver has plenty of angled blades for steam to pass through, leading to the exhaust fan. An alternative to this is a transom. This is a small, rectangular window that you can install above the door.

For another solution, you can put dehumidifiers inside the bathroom. This can help keep the space dry and fight mold from growing.

Last, there is cold water. This is a trick that some homeowners use. You turn on the cold shower for 15 to 30 seconds once you are done with the steam. It is important to note that you should do this before opening the enclosed door. This can help the moisture condensate and dissipate inside the space. That way, the steam will be gone once you open the steam shower door.
