If you want a steam shower generator guaranteed to work in North America, you’ll love this Superior 12kW Self-Draining Steam Bath Generator, which meets the standards necessary for ETL certification. Suitable for use with both steam showers and steam baths, the generator comes with a control panel that you can mount on the wall outside the shower or on a wall inside the shower. As the controls are waterproof, you won’t worry about the steam or liquid damaging them, and there are included controls that you can program for customized showers.

Two built-in steam outlets have a chrome finish that is waterproof and resistant to rusting, and these outlets help you use the 12 kilowatts to produce steam for a larger shower or two separate units. Thanks to a separate aromatherapy outlet, you can add a few drops of your favorite essential oils and enjoy the feeling that comes from those scents gently mixing with the steam and wafting over you.

Though Steam Spa makes a number of packages that come with different parts and accessories in a specific finish, the company also makes a number of steam shower generators like this Steam Spa D-900 9 KW Steam Bath Generator. With a nine kilowatt rating, this generator is powerful enough for even the largest of showers and will provide you with an almost constant stream or source of steam. It has built-in technology that allows the generator to produce steam in right around one minute.

With a maximum size capacity of 255 cubic feet, this generator will provide more than enough steam for a longer shower. It requires 220 volts to run and comes with built-in components for attaching your water line and other hoses as well as a purge setting that drains the water inside. This steam bath generator from Steam Spa is also one of the quietest generators we found and will run so quietly that you may never hear it.

Do you hate that you need to get out of the shower every time that you want to increase the water temperature or the amount of steam produced?

Those controls let you make all the adjustments that you need and are resistant to both water and rust.

It comes with a steam outlet with a chrome finish that is resistant to rust and other forms of damage and a second outlet that you can use for mixing your favorite essential oils with the steam. The generator works with most electrical systems too because it needs only 220 volts.

Superior also gives you waterproof controls that are resistant to rust, which you can install on a wall near the shower or on one of the walls inside your shower.

Steam Shower Generator Buying Guide

Proximity to Bathroom

One thing you should consider is how close that generator must be to your bathroom. Unless you have a lot of extra space in your bathroom, you probably want one that you can install outside your home or in a spot like your basement or attic. Though some generators must sit close to the steam showers, others can be up to 20 feet or more away from that shower.

Generator Power

Buying a generator that doesn’t have a lot of power is like throwing away extra money. Not only will it add to your energy bills, but that generator may keep the steam shower from working at its peak performance too. You typically want a generator with at least a one kilowatt rating, but you can go up to nine kilowatts for use with larger steam showers.

Run Time

Run time tells you exactly how long the generator will run and provide steam for your shower. Though some will provide an almost endless stream of steam, others will only work for shorter periods of time. You may want one with a timer that tells the generator when to stop its production of steam.

Wait Time

No matter why you want a steam shower in your home, you do not want to spend valuable minutes waiting for the generator to kick on and push steam into that shower. Cheaper generators generally have a longer wait time that can leave you feeling frustrated. Higher end generators can produce steam in seconds.


Never buy a generator for your steam shower unless it comes with a dependable warranty from the manufacturer. This warranty should last for at least one full year after your purchase. A good warranty will include the cost of new parts as well as the labor needed for repairs too.

Automatic Drainage

Steam shower generators heat water to a higher temperature to create steam, and most have built-in containers that hold the hot water. You should look for generators that have some type of automatic drainage feature that will drain the water later. This keeps bacteria from building up in the water and stops the generator from releasing that bacteria into your shower.

Automatic Shut Off

Cheaper steam shower generators often require that you turn the generator on and off each time you use the shower. Some of the more expensive models come with a shut off feature that automatically shuts the generator down when it runs out of hot water. This will keep the generator from overheating and breaking.

Ease of Use

There is no point in buying a steam shower generator unless it is easy to use. Pay close attention to the controls on the generator. Those knobs and/or buttons are what you will use to turn it on and off, change the water temperature and adjust its other settings.

Noise Production

You will typically want a steam shower generator that operates quietly and won’t make a lot of noise. If it vibrates, produces a loud humming sound or makes other noises, those sounds will keep you from relaxing in your shower.
