Best Steam Shower Generators Buying Guide

Ultimately, you might think that it’s the showerhead and panel that are important when it comes to a steam shower.

It’s easy to forget what goes on behind the scenes, but when it comes to it the generator is at the heart of any steam shower so a good generator means a good shower.   

Therefore, it is of utmost importance to choose the right generator and when doing so there is a lot to consider, for instance:  

Heat Up Speed   

How long a generator takes to heat up can vary massively from seconds to minutes.

This is important to think about when choosing a generator as the frustration caused by waiting, shivering, and being cold for minutes can really destroy the whole purpose of having a steam shower in the first place.     

Of course, only you can decide how important this is when buying a generator.

If your routine allows you to wait an extra couple of minutes before a hot and steamy evening shower then this might not be one of the most important factors for you. 

However, if your steam shower is to be used early in the morning when you’re racing to start the day then arguably this could be the most important factor.   


One thing that people often forget to consider when purchasing a generator is the measurements. The length, width, and height vary quite dramatically from model to model.

This is extremely important to think about as a generator that doesn't fit in your bathroom or required space is about as useful as no generator at all!   

When considering size, it is also important to look at how far away from the shower the generator can be plumbed as this can vary massively.

For instance, a generator may be far too big to fit within the space available in your bathroom but may be able to be fitted 50 feet away meaning that it could be put in the under stairs cupboard and still work perfectly for you.  

Noise Production 

One common connotation of machinery is noise.

When you first think of machinery you immediately imagine big, loud monstrosities that lead to noise pollution and annoy you and the neighbors day in and day out.  

But for many steam shower generators, this is not at all applicable.

Of course, to say that all of the generators on the market are noise-free would be wildly inaccurate however it does vary from product to product.  

For many, the whole purpose of a steam shower is to relax, unwind and switch off and an obnoxiously loud generator could not further oppose such ideas.

Therefore, if a peaceful environment is what you are after, low noise production should be near the top of your tick list when deciding on a generator for your home.  

However, if you are purchasing for purely practical measures such as improving your circulation a small level of noise may not disturb you too much.   

Price & Warranty 

Finally, it’s a good idea to consider your budget before you start looking for a steam shower generator.

Prices can vary quite dramatically depending on brand but, by doing a little research and shopping around, you may be surprised to find that you can find something equally as good for a lower price. 

While you’re looking at prices, take a moment to explore what sort of warranty your potential steam shower generator comes with as well.

The longer the better here, as this will cover you for repair or replacement and, ultimately, save you money in the unlikely event of something going wrong. 

Frequently Asked Questions

How Long Does A Steam Shower Generator Last?  

Of course, there are multiple factors that affect how long a steam shower generator will last such as the quality of the generator itself, how often it is used, and how well it is maintained.

Therefore, the best way to make a generator last a long time is simply to buy a high-quality model and to make sure that it is well looked after!

When all of the above is adhered to it is not unreasonable to suggest that the right generator, in the right situation could last for decades.  

Do Steam Showers Use A Lot Of Water?  

One common misconception of steam showers is that they use a lot more water than a traditional shower. Surprisingly, this is not the case at all!

In fact, a 20-minute normal shower can use more than 50 gallons of water, whereas a steam shower can run off as little as 2 gallons.

This just goes to show that the steam shower not only benefits your mind, body, and soul but also our environment, what’s not to love?
