What Is a Steam Shower Generator?

A steam shower is a watertight enclosure in your bathroom. It is important that the enclosure is properly sealed to prevent the water vapor from escaping.

The most important part of a steam shower is its generator — without it, there would be no steam. When cold water enters the generator, it is heated to its boiling point. This steam is then released when you activate the steamer in your shower.


Steam showers are relaxing and have health benefits, so many people sit on a bench or seat when using them. However, you should avoid using a steam shower for more than 20 minutes at a time to prevent overheating (1).

Steam showers usually have one or two shower heads that feature different spray patterns. Many look and function similarly to standard shower heads. If you install a steam generator in your shower, you won’t need a secondary shower area.

Advantages and Disadvantages

Until relatively recently, steam showers were a luxury mostly found in hotels and spas. However, they have become far more affordable in recent years, making them a valid option for more homeowners.


  • Improves blood circulation: Using a steam shower has been found to have a positive effect on cardiovascular health (2). Improved blood circulation encourages a healthier heart and helps reduce blood pressure (3).
  • Reduces stress: It is easy to feel deflated after a stressful day at work. However, a few minutes in your steam shower will help you feel refreshed. Studies have found that steam therapy reduces the body’s production of cortisol, a stress hormone (4).
  • Improves skin health: Toxins can become trapped under the skin’s surface and in our pores. Steam encourages your pores to open, releasing these toxins. You might enjoy clearer skin after spending time in a steam shower (5).


  • Expensive: The initial cost of a steam shower generator is less than it used to be, but it is still a significant investment. A good generator will usually cost anywhere between $500 and $5,000.
  • Installation: A steam shower generator should only be installed by an expert. If you aren’t confident that you can install it properly, call in professional help. Improper installation could cause leaks and damage to other parts of your bathroom.

How to Choose (Buying Guide)

A steam shower generator can transform your bathroom into a therapeutic area, but it is important to choose the right model for your home. Keep the following factors in mind during your search.

Proximity to the Bathroom

It is essential to think about where you will place your generator. If you have a large bathroom, you could be able to install it near the shower without it being visible. However, if your bathroom is small, you might need to find an alternative location.

Some generators can be installed far from the steam shower, while others need to be close to it. Consider where the generator can be installed and choose a suitable unit.

Power Output

Power output is also very important as this will determine how much steam a generator can produce. Choosing a unit with low power output, such as 3kW, means you won’t receive high-end performance.

To choose an appropriately sized generator, consider the size of your steam shower enclosure. A large enclosure will need more steam, thus more power. If you have a double steam shower, you will need an even more powerful generator.

As a general rule, make sure a generator produces at least 6kW. This should be enough for a small to medium-sized shower. If your enclosure is bigger, look for a unit that produces 10 or more kilowatts.

Even with a smaller shower, it can still be worth choosing a generator with a larger power output as it will deliver the steam faster.


It can be very difficult to get a sense of a generator’s efficiency before using it, so you will need to use some guesswork. Its power output will usually give a good sense of how well it will perform. A long warranty is a good sign that the manufacturer has faith in it to continue working effectively.


Steam shower generators require regular cleaning to prevent a buildup of limescale or minerals. This also helps to keep it running smoothly and performing at an optimal level.

Some generators feature self-cleaning technology, but these are rare and usually expensive. If a unit doesn’t have a self-cleaning feature, try to find out how much maintenance it will require.

Noise Level

Steam shower generators can produce sounds such as humming, buzzing, and even vibrating, depending on the model. When choosing a generator, consider its noise level and how it will affect you. If the unit will be installed in your bathroom or near a living area, try to choose a quiet generator.


Are Steam Shower Generators Worth It?

Steam shower generators are popular among homeowners looking to add some luxury to their bathrooms. These high-functioning systems provide instant access to steam bathing, which can help to increase circulation and flush toxins from the body.

In addition, steam shower generators have several other benefits, such as reducing stress and pain, improving sleep quality, and promoting overall health and well-being. With all these positives in mind, it’s clear that these systems are definitely worth the investment.

How Often Should You Steam Shower?

When it comes to taking steam showers, there is no right or wrong answer regarding how often you should do it. Some people prefer to take steam showers daily, while others find that a weekly or monthly steam shower is enough to keep their skin feeling soft and smooth.

Ultimately, the frequency with which you steam should be based on your individual preferences and any health conditions that might impact your comfort level in steamy environments.

However, if you are looking for general guidelines, one possible recommendation would be to steam at least twice per month for optimal benefits.

A weekly or even daily shower may be too much for most people. It can lead to dehydration and other negative effects. Of course, the exact timing will depend on your specific needs, so talk to your doctor about what approach is right for you.

How Long Do Steam Generators Last?

When properly taken care of, most steam generators will last anywhere from 8-10 years. However, some models may last as long as 20 years or more with proper maintenance.

A steam generator is a machine that produces and transfers steam, making it an essential piece of equipment for many industrial processes.

Factors such as the quality of materials and construction, the operating environment, and regular cleaning greatly impact how long a steam generator will last.

Overall, a steam generator’s life expectancy depends on the unit’s type and general operating conditions.

Can a Steam Generator be Too Big?

There is no clear answer to the question of whether or not a steam generator can be too big. Some experts argue that bigger steam generators have more surface area, which means they have the potential to generate more power.

However, others might argue that bigger generators take up more space and are less efficient overall.

Whether a generator is too big depends on individual factors, such as design and how it will be used in practice. In some cases, a smaller generator may be more effective than a larger one, depending on application and circumstances.

Still, for most situations, there does not seem to be any inherent advantage to having a larger steam generator compared to a smaller one.

Does a Steam Generator Need a Drain?

There is some debate among heating experts regarding whether or not a steam generator needs to be drained periodically. On the one hand, some believe these systems are natural and do not require this extra step to function properly.

However, others argue that without periodic drainage, mineral deposits and scale can build up in these units over time, causing problems with performance and efficiency.

Ultimately, the best approach depends on several factors, including the type of system being used and the overall maintenance history of the unit.

Regardless of which side you take in this debate, it is important to take preventative measures to protect your investment and keep your steam generator running smoothly for years to come.
