What To Look For When Buying A Steam Shower Generator

If you’re considering putting a steam shower in your home, you’ve probably already considered the therapeutic benefits as well as the health benefits that a steam shower can bring. What you may not have thought of yet is what to look for when buying a generator. Here are a few ideas of what to take into consideration before investing your time and money in a steam shower.

How Big Will Your Steam Shower Be?

You may have noticed by now that different steam generators all have different amounts of kilowatts. This has a direct effect on how much steam the unit can generate, and how large of an area that the generator will be able to fill.

The first thing you will want to do is to determine the cubic footage of your steam shower enclosure. This can be done by measuring and multiplying the length x width x height of your steam room. Finding the total cubic footage will help you to determine how many kilowatts your generator must be. Here is a basic breakdown of how much area each size generator can fill :

  • 7 kW Steam shower Generator: 101-250 Cubic Ft.
  • 10 kW Steam shower Generator: 251-450 Cubic Ft.
  • 12 kW Steam shower Generator: 451-550 Cubic Ft.
  • 15 kW Steam shower Generator: 551-675 Cubic Ft.

Different Styles And Colors

When looking for a steam shower generator, you will notice that there are not very many different options available as far as “looks” go.

Most generators look fairly similar to one another. Style and color of your steam generator shouldn’t really be an issue, because the generator is meant to be installed in a hidden area, such as under a bench, inside a nearby closet, etc.

Don’t spend too much time trying to find a nice looking steam shower generator, because chances are once it is installed, you will rarely see it.


All steam shower generators are not created equal. Some generators can be rather loud, and produce a number of annoying sounds.

If noise is something you want to avoid, there are a number of shower steam generators that are designed to run more quietly.

The best way to find a nice, quiet steam shower generator is to do some research. Read up on the product description page, and look online for reviews from other customers.

Price & Warranty

As you can imagine, you can find shower steam generators on both ends of the price spectrum. You can spend anywhere from $100 up into the thousands of dollars.

The price differences will be related to brand name, quality, size, components, and features. The more spendy units are self-draining and made with quality components and fittings, where many of the cheaper models you will find must be manually drained after each use.

As a general rule, the larger the steam shower generator, the higher the price will go. This correlates directly with the size of your steam room and how much steam you need your generator to produce for you.

Some other features that the more expensive steam generators may have can include digital LED time/temperature displays, remote control, lights, and music features, as well as built-in aromatherapy options. How far you want to go with features is up to you.

You may also want to take warranties into consideration. Some brands offer an appealing warranty on their pricier models. As with any other piece of working equipment, your steam shower generator will be doing a lot of work, and will eventually need maintenance or even replaced. You may want to choose a steam generator that has at least a 1-year warranty.

The most important thing when buying a steam generator is to buy one that has the correct amount of power to fill your steam room efficiently. Once you get the size of your generator figured out, then you can move on to exploring different features and different models.

Steam Shower Generator FAQ

How do I clean my steam shower generator?

A: Some steam generators come with an auto-cleaning system, that can be used to flush out your system with the push of a button. Even if Your unit does have this feature, you will still want to take apart your generator and manually clean it once in a while.

Make sure your generator is powered off and has cooled down. You can then drain the unit, take off the entry panel to the unit, and manually scrub the inside with a household cleaner or vinegar. You may need to use a screwdriver, or other scraping tool to scrape away calcium buildup.

How do I install my steam shower generator?

A: The first thing you will need to do is decide where your steam generator will go. Keep in mind it must be near a power supply, as well as close to water hookups. Keep in mind that your steam shower must be sealed to keep the steam trapped inside.

The steam shower will need to be tied into your existing plumbing. You will also need to run a wire from your home breaker box to the generator. Steam generators will require their own dedicated circuit breaker to operate. This will keep your breakers from tripping. You will need to hook up the drain outlet, as well as the steam head to the inside of your shower.

Be sure to follow all manufacturer installation instructions, and go step by step. If you are uneasy about hooking your generator up yourself, you can always hire a professional to help.

What size steam shower generator do I need?

A: To find the proper generator size, you will first need to take some measurements of your steam shower and find the adjusted cubic footage. Once you have found this number, you can find the proper amount of kilowatts your generator will need to fill your steam room.

The tiles, glass, and materials used inside your steam shower can also have an effect on how your steam generator will perform. There are several tools available online to help you size your generator for your steam shower. Here is a link to a handy sizing tool.

Should I buy a steam shower generator kit?

A: If you are intimidated by the idea of building your own steam room, finding the right generator, and figuring out how to hook everything up on your own, a steam shower kit might be a good option for you.

These kits come with the actual enclosed shower unit, which you can install inside your home. On top of already having the steam shower space built, these kits also come with everything you need to get your steam shower up and running in little time.

Although kits may be a more expensive route, they can take a lot of the guesswork out of setting up your steam shower.
