How to Choose the Best Steam Shower Generator
Picking the right steam shower generator isn’t just about grabbing the first model you see. It’s about matching the machine to your space and your personal relaxation style. I’ve found that focusing on a few key areas makes the whole process much smoother and ensures you get a unit you’ll be happy with for years.
First, and this is the big one, you need to get the size right. This isn’t about the physical dimensions of the generator itself (though you need to know where it will fit), but its power output measured in kilowatts (kW). A generator that’s too small for your shower enclosure will struggle to produce enough steam, leaving you underwhelmed. A good rule of thumb is that you need roughly 1 kW for every 50 cubic feet of space. To find your cubic footage, just multiply the length, width, and height of your steam room. Don’t guess on this; an undersized unit will run constantly and wear out faster.
Next, think about the control system. This is your interface for your steam sessions. You have a few options here. Basic models come with a simple dial timer that you turn to set your steam time. Digital controls offer more precision, allowing you to set exact temperatures and durations, often with a memory function for your favorite settings. The premium option is a digital control with a steam-rated remote, so you can start your session from inside the shower without reaching outside. I prefer a digital control for the accuracy it provides.
The steam head might seem like a small part, but its placement is critical. You want it to be located about 6-12 inches off the floor, typically on the wall opposite the bench. This allows the steam to rise naturally and fill the space evenly. Make sure it’s positioned so it won’t be directly hitting you or any shower fixtures. Also, check what material the steam head is made from; brass is a durable, corrosion-resistant choice.
Finally, consider the construction and features. Look for a generator with a stainless steel or copper tank. Copper is excellent for its natural anti-microbial properties, but stainless steel is also very durable. Some models offer an “auto-flush” or “auto-drain” feature, which is a huge plus. This function clears any residual water from the steam line after each use, preventing stagnant water and mineral buildup, which extends the life of your unit.

Frequently Asked Questions
Where should I install my steam shower generator?
The generator itself needs to be installed within a certain distance from your steam room, usually no more than 25 feet away, and ideally on a dedicated, GFCI-protected electrical circuit. It can be installed in a closet, vanity cabinet, attic, or even under a bench, as long as the location is dry and has some access for potential future service. The key is to follow the manufacturer’s instructions for the maximum steam line run. A professional installer will know how to place it for optimal performance and safety.
Can I use my regular shower as a steam shower?
Yes, but it requires some specific modifications. A standard shower stall needs to be fully enclosed to trap the steam, which usually means adding a door that seals well and a ceiling that isn’t too high. The walls and ceiling should also be made of non-porous materials like tile, glass, or solid surface, and you’ll need a vapor-proof light and a sealed shower door. It’s not just a matter of putting a generator in; the entire enclosure has to be converted to handle the consistent moisture and heat.
How much maintenance does a steam shower generator require?
Maintenance is relatively minimal, but important. If you have hard water, using distilled water is the best way to prevent lime scale and mineral buildup inside the generator tank. If you use tap water, you’ll likely need to descale the unit periodically, following the manufacturer’s guidelines. Many modern units have an auto-flush cycle that helps with this. The other main task is keeping the steam head clean and free of any blockages. A well-maintained generator can last for many years.
Is it safe to use a steam shower if I have health concerns?
For most people, steam showers are very safe and beneficial. However, if you have specific health conditions like high or low blood pressure, heart disease, or are pregnant, it is absolutely essential to consult with your doctor before using one. The heat and humidity can affect your cardiovascular system. It’s always best to start with shorter sessions at lower temperatures and see how your body reacts. Listening to your body is the most important safety rule.
What is the typical warm-up time for a steam shower?
You won’t be waiting long. Most quality residential steam generators will bring your shower enclosure to a comfortable steam in about 2 to 5 minutes. The exact time can depend on the size of the generator, the size of the room, the starting temperature of the water, and the ambient room temperature. A properly sized unit, as recommended in any good 10 Best Steam Shower Generators – Reviews & Selection Guide, should get you steaming quickly.
Can I install a steam shower generator myself?
While a very experienced DIYer with knowledge of plumbing and electrical work might be able to handle it, I generally do not recommend it. The installation involves high-voltage electricity, plumbing connections, and often working within building codes. A professional installer ensures that the unit is correctly sized, properly wired, and that the steam room is adequately sealed and prepared. This guarantees both your safety and the optimal performance of your investment.
