Does Steam Bath Room Have Any Health Benefits?

As an old culture practiced in the ancient Greek and Romans Empires, using hot (warm) springs, a steam bath was adopted for health purposes. Even in some parts of Africa, some people inhale steam from a local concoction (usually made for typhoid and malaria treatment, and this practice has been in existence for centuries). While the earliest men were unable to tap into the realm of a steam bath entirely, the evolution of steam rooms made it possible for scientists to discover numerous benefits of steam therapy. The list is as follows: 

  • Clear congestion 

For people that often experience blocked airways caused by mucous, a steam bath can help clear the nostril and make your breath better. Steam rooms are primarily functional during cold symptoms to warm up the body system. If you’re battling an allergy-like cough or catarrh, steam showering would improve your condition but shouldn’t be a replacement for over-the-counter treatment (OTC). 

  • Improve skin health 

A steam bath causes you to sweat, and this process helps open the pores and thus cleanse the skin. How is this possible? The warm condensation rinses away dead skin dirt that can degenerate into skin breakout. Steam room showering is also an essential procedure in acne treatment

  • Blood pressure regulation

According to a study, bathing with steam helps the body release an aldosterone hormone which helps in lowering people’s blood pressure (BP). Therefore, a steam room is an excellent option if you face BP because the cooling effect keeps you in a relaxing mood while regulating your heart rate. 

  • Bronchitis

Just like humidifiers are good for easing bronchitis, a warm bath inside a steam room or inhaling steam during showering loses phlegm and helps reduce complex breathing problems during bronchitis.

  • Improve circulation 

When blood vessels are dilated, it hinders body circulation activities. However, staying in steam rooms helps enlarge the blood arteries as the heat changes the body temperature, causing blood vessels to function correctly.

Risks Associated With Steam Rooms

Sure, steam rooms have their benefits, but it is also wise to know the risks involved. Finding shows staying too long in a steam room, like more than 15 (fifteen) minutes, can cause dehydration. If you don’t want to be dehydrated, endeavor not to stay too long inside. 

Bacteria and germs can also build up in steam rooms as the steam being produced are not hot enough to kill them. Therefore, it is advised to clean it often and not spend too much time inside, as said earlier.

People with specific conditions such as the ones listed below are not advised to use steam rooms irrespective of the benefits:

  • Pregnant women 
  • History of stroke 
  • Heart problems 
  • Battling with coronary artery disease 
  • Experiencing low blood pressure 
  • Just undergone or recovery from surgery 
  • Having bacteria attack skin infection

For severe conditions of the form listed in the benefits section, steam rooms are not a treatment option. It is only a bath solution, but the excellent aspect has made us recommend its use. Therefore, studies have seen it as a bathing option, not a medical solution. Possible before getting one for yourself, consult your doctor to know if it is suitable for your health status; this way, you’ll be safe from risks. 

Steam Rooms Vs. Sauna Are They The Same?

They are not the same but perform a similar function, and both allow you are sitting inside steam. Sauna is more petite and produces hotter dry heat than that steam rooms. Here is a typical example of a sauna.  

Generally, a sauna uses an electric heater, stoves, or hot rock to produce steam, unlike steam rooms that use steam generators to heat water passing through its vacuum. Sauna is also beneficial to keep you relaxing and the losing muscles, just like a steam room. Illustration of a steam room here.  

Why you may be wondering which one is best, the humidity option offered by steam rooms makes them better in the eyes of the majority. 

How To Find The Best Steam Shower Generator 

Every prospective buyer wants the best of the best when picking a steam shower generator for their bathing room. Getting the right option is essential for not wasting your money. In making the decision, many factors account for, which are enumerated below;

The volume of the steam room:

No one steam generator has the power you cover different steam room sizes. Every unit has its coverage capacity or ratings, and this information can be accessed on the body of the respective gadget written by the manufacturers. Therefore, to know the exact size of your facility, you need to know its length and then go into the market with the figure gotten to pick what matches the value. To determine the volume of your steam room area, use the manual steam generator calculator formula:

Find the length, width, and height and multiply the figure by 2. For example, L= 12, Width = 10 and H = 13 

Volume = 12 x 10 x13 x 2 = 3120 cubic feet.

After calculating the volume, use the figure gotten to size the suitable machine that can power your space—however, the bigger the steam room, the more capable device is required. 

Power consumption: 

While the heating bill could scare people into investing in this shower appliance, it is good to know that running a steam shower generator is pretty not expensive as you might’ve thought. The amount of energy used is dependent on the size shower room; the bigger the size, the more steam to be released, and the more energy consumption. However, it’s always the best idea to look for energy-saving rated units such as the KOHLER K-5533-NA 5533-NA Invigoration STEAM Generator or any alternative found in the market. 


When buying a steam generator for a shower room, the dimension is vital to consider. I’m sure you don’t want something that will occupy the whole space in your bathroom. Hence, for smaller areas, a small footprints generator would be excellent. Nevertheless, if your property is larger, you have no option to choose a bigger capacity, and this dimension will also increase. In essence, the size should fit without requiring much space. 


This factor is only significant when strategizing the installation process. The heaviest unit may be challenging to lift during installation. The steam generator should not be too heavy to ease the installer or plumber’s task.    

Start time: 

From findings, different steam generators have time to heat water, and from tested products by users, most unit takes 10 minutes. However, advanced units can heat up faster. You’ve to check the required time it will take to produce steam for the prospective choice. However, most large-capacity generators need more time to warm up the water. 

Automatic drain:

This feature helps drain any unused water from the device and helps maintain it as stagnant water may have a corrosive effect, even causing bacteria and germs to grow once the water is cooled down. But most people neglect this aspect; we, therefore, advise you to check for it or check the SteamSPA Shower Generator featuring this self-draining function. 

Control panel: 

An easy-to-read and understood control panel will help you have the most effortless operation when showering. Complex designs could make some people challenging to use, especially if you’ve visitors (guests). Features like timer setting are also great, as it helps you determine how long you want to spend while bathing and turns off once the required reaches. Also, models with automatic timers help turn off the generator once the timer turns off, making it a user-friendly and hassle-free operation. 

Noise level:

One of the most critical aspects is the noise level. If you live in a rented apartment or have kids at home, you wouldn’t want to wake them up each time you use your steam generator. Though most products out tend to be noise friendly, the level but a check still needs to be done to get the quietest one possible. 


Another vital aspect is the warranty. Steam generators are luxury items and can cost up to a thousand dollars and above. You don’t want to risk your investment as the case may be for some defaulting shipped unknowingly. Manufacturers and vendors that offer a warranty of at least not less than one year and above are worth it. 

Steam Shower Generator Installation (How To Install)

Installing a steam shower generator is not for the armature since it costs a fortune to acquire one. We do not recommend a do-it-yourself installation unless you’re a licensed plumber. Therefore, this section is for installers or anyone who want to learn the technicality of mounting and connecting steam shower generators. 

If you’re an expert in this field, the installation will be a work-over process as your years of experience and knowledge would give you an edge. Basics steps to follow;

This will also determine the easy water supply to your shower head and the machine’s draining when not in use. You may also consider the accessibility should in servicing and maintenance needs.

The steam line refers to the steam head, and it should be connected 6 to 12 inches from your shower floor. 

#4. Install the drain line:

1-inch required gap for indirect drain system. But for more options, check your area’s local plumbing code.

Also, check for a pressure relief valve, trap, vent, and receptor requirements from your national and local plumbing code. 

#5. Electrical wiring: 

Before beginning any electrical wiring, ensure to switch off the power supply. To do this, follow the steps:

  • Use copper wire only. Follow your local electrical code requirement while also ensuring it matches the device amperage rating. 
  • Install a circuit breaker. This will be a power disconnect between the circuit and the steam generator. Then plug in the machine to the circuit.

#6. Test your installation:
