What is a Steam Shower Generator?

A steam generator is a machine used to convert water into steam. Cold water is boiled and converted into steam with the help of the generator. Once water is converted into steam, it is delivered to your steam room under controlled temperatures. Most steam shower units come with a generator. Depending on how the original generator performs, you may be obliged to invest in a separate, reliable steam generator.


A steam generator is often equal in size or smaller than a briefcase. Most of them resemble a car battery in design, except for the fact that they are often smaller and much lighter. When buying a steam generator, sizing it up to ensure it can deliver the steam needed to keep your steam room luxurious is important. However, sizing your steam generator does not in any way relate to its physical size. That is because most steam generators are similar in size almost all of the time. A 3kW steam generator, for example, is most probably similar in size to a 9kW generator, but the power capabilities are different.

Power Rating

Now that you know that the generator’s physical size is no an indicator of its performance; here is something that actually matters. A generator’s power rating ranges between 3kW and 12Kws for the home shower system. The higher the power rating, usually the more powerful the steam generator is. A 3 kW steam generator, for example, powers enough steam for a 1 person steam shower efficiently.

When you use it in a 500 cubic feet steam room it will certainly struggle to deliver steam. A standard generator delivers at least 6Kws of power. This can, in turn, provide a fast steam build up time of two minutes or fewer, and then deliver enough steam in the room throughout your shower period accordingly.


One of the reasons why shower units can be expensive is because of their generator. As a separate unit, a steam generator can cost in excess of $1,000. Most generators range between $1000 and $2000. Of course, what you want to pay more attention to is the generator’s power rating, control features and anything else that will assure you of an impressive performance for long.

Buying Guide for Choosing the Best Steam Shower Generator

Having a steam generator that can build up steam in the shortest time possible is the goal of every steam room owner. Unfortunately, most of the steam generators sold together with the steam shower don’t last long. Those that do either take too long to build up steam or they are unreliable at times. When you decide to buy your next steam generator, therefore, keep in mind some of the following tips, mentioned in this buying guide.

  1. Power Output

    A steam generator’s power output is probably the most important factor you need to keep in mind during this process. A generator will work efficiently depending on how much power it can produce. If you buy a 3kW steam generator, it will perform within the limits of a 3kW generator. You get what you pay for, remember? With that in mind, evaluate the size of your steam shower and select a generator powerful enough to steam up that room.

    For a very small steam room, a 3Kw generator could do the job. But to be on the safe side, select generators with a power output of at least 6 kilowatts. If you have a 2 person steam room, select an even bigger steam generator. Besides the ability to deliver enough steam for a big steam room, a powerful generator is also more likely to build up the steam faster. And that is a great thing because you save on time.

  2. Quality

    Imagine this. You have a powerful steam generator. You bought it at a killer price. Unfortunately, the generator only lasts six months. How would that make you feel? Since you will want to enjoy steam showers after the six months, you will be forced to buy another steam generator. In the end, your steam shower will be costlier than getting the services from a health spa. Consider quality in construction and quality in performance in equal measures. If a steam generator performs well but looks poorly built, don’t invest in it.

  3. Components

    A quality steam generator features a myriad of helpful components. It should have a quality connecting wire. A wire longer than 10 ft. is the standard. It should have outlets for linking to aromatherapy scents, a radio outlet or a wand. Make sure, therefore, that as you buy a steam generator, it offers the value you can see. Look at the generator’s control panel also, and ensure that it has dials that will help you improve your experience using it.

  4. Efficiency

    Most people value a steam generator based on its efficiency. Unfortunately, you can’t tell if a generator is efficient before you use it. Can you? What you can do, however, is go through its customer ratings in online retail stores and view its performance features. Getting to know what people who already own the generator feel about it can help you decide if you should buy it. Additionally, features that can help you evaluate the generator’s efficiency include its power output and the length of its warranty. Usually, generators with lengthy warranties are most often good in quality and performance.

  5. Noise

    Like any other machine, a steam generator produces noise as it functions. That’s why most experts will advise you to install your generator in a cabinet. To ensure you have minimum noise pollution in your bathroom, select a generator with the lowest noise level. Noise in generators is measured in decibels, and the lower the decibels, the quieter the generator will be.

  6. Functionality

    Determine the goal of buying your generator long before you decide to buy it. Do you want a generator for residential use? Do you need a steam generator that can increase steam build up time? You will most likely find your ideal steam generator when you already have clear reasons why you need it.

  7. Cleaning Features

    Often underscored, cleaning a steam generator is important if it is going to last for long. You will be lucky if you buy a generator with self-cleaning technology. If you choose one with no automatic cleaning, consider carefully how the manufacturers recommend that it be cleaned.

  8. Startup Time

    How long does it take for the generator to fully function? A quality generator should power on and begin to build up steam immediately. It is the reason you probably invested in this generator after all. Many manufacturers do indicate the generator’s start-up time. Check carefully for this. If you can’t find any indication, go through the machine’s online reviews. You will find helpful information on how fast to slow it takes for the generator to start up.

  9. Safety

    When installing a steam generator, professionals will often advise you to install at least two circuit breakers. That’s because these small machines hold too much power on them. They are risky and deadly if they function in a manner that could endanger you. If the unit, for example, is poorly engineered, it could fail and expose you to accidents.

  10. Price and Warranty

    If you purchased your current steam shower for less than $1500, you will be surprised to learn that some steam generators costs higher than that. Steam generators are expensive, which is why you need to invest time knowing exactly which one suits your needs. Once you know what generator you need, you can compare prices and warranty and invest in the most ideal machine.

Other than safety, your desired location should be a place nearby your bathroom’s water lines for easy connection.

Installing the Generator

Once you settle on the right place to install your generator, prepare your drilling tools. You will need two holes; one that connects the generator to the control panel and one that connects it to the steam outlet. Note that some states have general installation rules you are required to follow. Most states, for example, require a 1-inch gap for the drainage system. As for electrical connections, ask a professional for assistance or follow manufacturer’s guide accordingly.

Depending on the generator’s power rating, use an insulated copper conductor for the wiring. Install at least two circuit breakers for complete safety. One circuit breaker can be installed between the generator and the power supply and the other one in a nearby location.

Finish up Installation

If the steam generator’s control panel asks for separate installation, install at your convenient location. Once done, turn on the water to test the system. Ensure that power is off though because you want to test the generator’s performance first. Small issues that may be hindering efficient steam delivery could include holes and cracks should be addressed immediately. If everything is running on as expected, you are good to go. Installing the steam generator is something that could cost you a few years, but it is worth it when done correctly.
