How Does a Steam Shower Generator Work?

Steam shower generators collect and hold water, heating that water until it turns to steam. It then pushes the steam to the shower, where you get to relax and enjoy the many health benefits. High-quality steam generators will be energy efficient, produce quality steam quickly, and maintain the steam for the set runtime. The best will also have quality parts, drains, and low maintenance.


5 Benefits of Using a Steam Shower

There are several well-known benefits to using a steam shower. Let’s take a look at those benefits now.

1. Improved blood circulation

Heat from steam can increase the capillaries, allowing the blood vessels to dilate. This increase in blood flow moves oxygen through the body more efficiently. In turn, you feel less fatigue from normal tasks and exercise.

2. Clearer/cleaner skin

Steam is known to open pores and help clean them out. Clean pores promote healthier skin by reducing irritation, acne, and can reduce the redness and swelling from rashes.

3. Melts away stress

Steam flowing over the body has been shown to relax muscles, especially in the neck, shoulders, and back, where we carry our stress. By relaxing these muscles, you can feel your stress melt away.

4. Promotes weight loss

As you bathe in steam, you sweat. The excess water from your body is removed, which can lower your weight temporarily. However, this temporary weight loss can be the catalyst needed to see improvement by losing fat weight, not just water weight.

5. Clears and opens sinuses

Breathing steam is shown to expand the sinus cavities and increase the blood flow throughout the sinuses. Doing so helps clear out any congestion and diminish swelling, helping you breathe easier.


Guide to Buying a Steam Shower Generator

Below, you will find a brief outline of steam shower generators that you need to be conscious of. Before making your final decision, consider these factors.

Generator Size vs. Steam Shower Size

The size of the generator will determine how much steam it can produce and for how long.

Larger generators work longer and more efficiently to produce steam for long-term use. 

Most steam showers are designed for more than one person. They generally won’t fit in an existing bathroom.

Steam Generator

Most installations are built outdoors, near the bathroom of the home, to use the plumbing and water supply from there. Because of this, a lot of steam shower generators need to be close to the shower installation. Some high-end models can be effective from over 20 feet away, though.

Generator Power & Voltage

Steam generators require electricity to operate. There are three main power supply options, including a standard 110-120v outlet, or hard-wired to a 220v circuit. Depending on the model you choose, you will need to accommodate the power requirements. Each steam generator is rated at a specific kilowatt power. For the most part, they use 1 kilowatt, though larger, more powerful models can reach 5, 10, or more kilowatts.

Run-Time & Wait Time

Another thing to consider is the waiting time. Like most water showers, you will need to let the generator get hot enough to produce steam. You will also need enough steam to make the steam shower worth it. Cheaper models will take several minutes to reach the right temperature and produce enough steam. More expensive models, though, can be ready in a matter of seconds.

Automatic Drainage

You will want to look for a model with automatic drainage. Unlike manual drains, automatic drainage prevents bacteria growth and helps the generator perform better. Manual drains will need to be emptied as soon as they are turned off, which is likely the last thing you want to do after a relaxing steam shower.

Automatic Shut Off

Because of the heat generated by the steam shower generators, most will come with an automatic shutoff feature. This prevents the generator from overheating and will prolong the life of the generator and its motors. If your model doesn’t have this safety feature, you may want to look at a different model.

Ease of Use

Steam Shower Home Depot

Steam showers and their generators should be simple to operate. It is hard to relax if you are growing frustrated at the shower.

Installation is generally straightforward, though it can take some time and effort. Once installed, and mounted correctly, you can enjoy the benefits of the steam the generator produces.

The shower itself should have simple controls, safety features, and sensors to prevent scalding or damage to the shower, the generator, or you.

Price & Warranty

Steam shower generators need to be affordable. As long as the model you want is within your budget, you won’t have any problems. Looking outside your planned budget range will only lead to worries, frustration, and anything except relaxation. Make sure your steam generator has a warranty that covers all parts, labor, and defects. A minimum warranty should be 12-months, though many go beyond this time frame.

Steam Shower Generator Installation

Most steam generators can be installed as a DIY project. You should adhere to all safety precautions, especially when dealing with electricity. A typical residential steam generator will run off of 220 volts, which can do a lot more than cause physical harm.

If you are ever in doubt, hire a professional to install your steam shower. Each model will come with detailed installation instructions, best practices, and general locations. You can mount the generator in a lot of places, including the attic, under the shower bench, in the bathroom along the wall, etc. 

As a general guide, you will follow installation instructions like:

  • Mount the generator level and upright.
  • Connect the water inlet using copper pipe to the steam head (about 9 to 12 inches from the floor).
  • Install the drain line with a minimum 1-inch down-pitch for draining.

Note: the previous step may require permits, traps, pressure relief valves, etc. Check your city code for details.

  • Install the power cables and run to a secondary circuit switch before running to the main breaker panel. The secondary switch should be easily located.
  • Run the power lines to the control system and test for power.
  • Install the control system in the shower.
  • Turn the system on and check that it makes steam.

For more detailed instructions, you can view this video for proper installation.


How to Size a Steam Shower Generator

The shower size, along with the room size, ceiling height, and construction materials, will all go into adequately sizing your steam shower generator. For the actual generator, you will need to know the cubic footage. To get the cubic feet, measure the length, width, and height of the generator and multiply the numbers together.

You also need to account for the kilowatts used by the generator and the power supply requirements. 110-120v options aren’t as powerful as 220v models. Choosing the right kilowatts will also matter. 1 kilowatt is the minimum, but models range from 1, 5 to 10, or even 15kW.


People Also Ask (FAQs)

Do these units vibrate or hum, or are they completely silent?

High-quality steam shower generators are mostly silent. Cheaper models will vibrate and produce more noise. If you are trying to relax in a steam shower, a vibrating and noisy unit won’t work well.

How much water does a steam shower use?

On average, a steam shower will use about 1-gallon of water every 15 minutes of operation.

Is it necessary to call a professional plumber for installation?

Some areas will require professional installation. You may be required to get permits, have a license, or meet strict building codes. A professional install in these cases is needed. Otherwise, with basic plumbing and tool knowledge, a steam generator can be a straightforward DIY project.

How much does it cost to build a steam shower?

A steam shower will cost whatever you want to spend. The minimum professional installation nationwide, averages about $2,000. However, if you want a custom shower, lighting, music, or other features, you will pay more — the installation price range averages between $2,000 and $5,000.

How often should I use a steam shower?

Like a hot tub, a steam shower should only be used for 15 to 20 minutes at a time. If you plan to use it more than once a day, a minimum of 20 minutes cooling off is recommended. Some users find the most benefits using a steam shower once a week, while others prefer every other day steaming.

Does a steam shower need to be enclosed?

The steam shower needs to be completely enclosed. Special steam gaskets are required on the shower door, too. All this to prevent the steam from escaping the shower.

What should be done to maintain steam shower generators & do they require any regular servicing?

Steam shower generators require little if any maintenance. Because they are sealed systems, there isn't much to do. However, you should regularly inspect the units to make sure there aren't any leaks, damage, or debris build-up that could cause a malfunction.

Where can I buy a steam shower generator for sale?

The best place to buy a steam shower generator is through Amazon. While most vendors sell their own on their websites, you will find better deals on the generators through the Amazon site. New models are the most expensive, and you can save a lot of money buying the current or previous model, still new-in-box, that is no longer offered on the company site.
