Product Reviews

When we searched for the best steam shower generator, we carefully considered the above points, for units to suit both smaller and larger showers.

Material quality and power are the two most important things to consider here. Using this as well as expert advice and customer feedback, we’ve created a list of the best steam shower generators on the market.

1. EliteSteam 12 Kilowatt Luxury Steam Shower

Best 12-Kilowatt Steam Shower Generator

For larger steam showers, this EliteSteam model is an excellent choice. It has a power output of 12kW, which is perfect for an area between 450 and 550 cubic feet.

EliteSteam is a leading brand when it comes to steam generators. The brand manufacturers high-quality units backed by Steamist, which has been leading the steam and sauna industry for over 60 years. We particularly like that EliteSteam makes steam generators surprisingly affordable.

Along with the generator, you get in-shower controls for easy operation. There are also a few smart settings to suit your shower.

What We Like

Impressive Warranty

EliteSteam offers one of the best warranties you can get. Residential steam bath generators, accessories, and controls are covered by a one-year warranty. This covers any malfunctions or defects due to manufacturing.

After one year, the parts are covered by a limited 10-year warranty, giving you peace of mind. The parts of a steam generator are more prone to damage than the generator itself.


Many 12kW generators can be quite large and difficult to install in tight spaces. However, this generator is compact and can easily be installed wherever there’s room. EliteSteam claims it can be installed underneath counters or nearby closets.

Everything Is Included

You get everything you need to install the generator right away. The package includes the generator, internal shower controls, steam head, and cable.

The controls come in three different finishes, including brushed chrome, polished chrome, and polished nickel.

High Quality

One of the main reasons we love this generator is its undeniable quality. The generator is made of stainless steel, and all other components are made to last for years to come.

What We Don't Like

Might Be Too Powerful

Keep in mind that a 12kW steam shower generator is on the higher end of the power scale. If your shower or bathroom is relatively small, this may generate too much for you. Alternatively, consider the EliteSteam model in our second spot.

Product Specs

Kilowatts 12
Material Stainless steel
Dimensions 17.8 x 7.5 x 15.5 inches
Cubic Footage Steam Room Up to 550 cubic feet
Warranty One year for malfunctions followed by 10 years for parts

2. EliteSteam 10 KiloWatt Home Steam Shower Generator

Best Generator for Smaller Showers

If you liked the 12kW EliteSteam generator but felt it was too powerful, this may suit you better. This unit is slightly smaller but will work excellently in an area between 251 and 450 cubic feet.

Again, the warranty is one you simply can’t argue with. This generator is also covered similarly to the 12kW — generator, accessories, and controls are covered for one year against malfunctions or defects. The generator parts are then covered by an extended warranty of up to 10 years.

With your purchase, you get internal controls, a steam head, and cable, so you can install the generator straight away. The controls are available in three finishes, including brushed chrome, polished chrome, and polished nickel. These options make it easy to match the controls to your shower fixtures, so it won’t look out of place.

The 10kW is compact and easily installed in tight spaces. If you have extra space in your bathroom, you might be able to install it inside the room.

High Quality

This generator was built to last with stainless steel at its core. All parts, accessories, and controls are also of high quality and should last you a very long time.

Due to the durable materials of the control panel, it can be installed anywhere you need it. It’s safe to place it inside the steam shower as well, which adds to the convenience factor.

What Is a Steam Shower Generator?

A steam shower is an enclosed, watertight space within your bathroom. Everything surrounding the steam shower has to be sealed tightly enough to prevent vapor from escaping.

The most important part of a steam shower is the generator — without it, there’d be no steam. As cold water enters the generator, it heats the water to the point of boiling. When you turn the steamer on in your shower, it’s released from the generator.

Take Note

Most people like to spend significant time in their steam shower to enjoy the relaxation, so a bench or seat is optimal. However, it isn’t recommended to spend more than 20 minutes at a time to avoid overheating (1).

Steam showers typically consist of one or two shower heads that feature different patterns. Many will look similar to regular shower heads, and work similarly. Once you install a steam generator in your shower, you won’t need a secondary shower area.

Advantages and Disadvantages

Steam showers used to be a luxury mostly found in hotels and spas. However, nowadays, steam generators are much more affordable, and widely available.


  • Improves blood circulation: Using a steam shower has shown to improve one’s cardiovascular health significantly (2). Improved blood circulation can lead to a healthier heart as well as help to lower blood pressure (3).
  • Reduces stress: Coming home after a stressful day at work can be defeating. However, a few minutes in your steam shower, and you can feel refreshed. Studies have shown that steam reduces the body’s production of the stress hormone cortisol (4).
  • Improves skin health: Toxins are often trapped underneath our skin and in our pores. As the steam hits your skin, it helps to open up the pores and remove the toxins. You might experience clearer skin after spending time in a steam shower (5).


  • Expensive: Although the initial price of a steam shower generator is more affordable than it used to be, it isn’t a cheap investment. When buying a good generator, you can expect to spend anything between $500 and $5,000.
  • Installation: Installing a steam shower generator should be done by an expert. If you’re unsure of how to install it properly, call a professional to help. If it isn’t installed properly, it could leak and cause damage to other parts of your bathroom.

How to Find the Best Steam Shower Generator

Having a steam shower in your bathroom has many benefits for you and your loved ones. But, choosing the right one is crucial. With such a range of choices, how do you decide? Consider the points below before settling on a generator:

Closeness to the Bathroom

Where the generator will be located is an essential thing to consider. If you have a large bathroom, you might be able to install it close to the shower without it showing. However, if your bathroom is on the smaller side, you might want to find an alternative location.

Some generators can be installed far away from the steam shower, whereas others need to be close. Consider where the generator can be installed and choose a unit to match.

Power Output

Power output is also very important to consider. A steam generator will create steam depending on how much power it produces. Choosing a unit with low power output, such as 3kW, means you can’t expect high-end performance.

To find the right size generator, consider the size of your steam shower. A large shower will need more steam and therefore more power. If you have a double steam shower, you’ll need even more power from the generator.

A good place to start is by choosing a generator that produces anything above 6kW. This should do well in a small to medium-sized shower. If yours is bigger, go for a unit that produces 10 or more kilowatts.

We highly recommend purchasing a generator with a larger power output because it will deliver the steam faster.


It can be nearly impossible to tell a generator’s efficiency before using it, but there are ways to get an idea. The power output of a steam generator can give you a good idea of how well it will perform. A lengthy warranty also usually means the quality and performance is efficient.


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

Some generators feature self-cleaning technology, but these are usually expensive and hard to come by. If yours doesn’t have a self-cleaning function, consider how the manufacturer recommends the task to be done.

Noise Level

Steam shower generators can produce various sounds such as humming, buzzing, and even vibrating. When choosing a generator, consider its noise level and how it will affect you. If the unit will be installed inside the bathroom or close to a living area, a low noise level is important.

Full Steam Ahead

Having a steam shower in the comfort of your own home can bring you the ultimate relaxation after a stressful day. Steam showers come with many benefits to our health and body, such as improved blood circulation and clearer skin.

Finding the best steam shower generator for you requires careful consideration of size and power. If you’re happy with the potential noise and energy requirement, go for a larger output, such as 12kW, for ultimate steam. Don’t forget to consider where the generator can be installed if you don’t have room in the bathroom.
