What is a steam shower generator?

A steam shower generator, otherwise known as a steam machine, refers to a device that heats water to its boiling point, and then disperses the steam through the pressure heads in your showering area. They are ideal for people who prefer to shower with hot steam, similar to a steam room. 

Typically, steam shower generators are portable with some of them measuring about 16 inches wide, 13 inches high, and 6 inches deep. This makes them easy to install in your bathroom, in areas such as the closet.

Steam Shower Generators Decision-Making Factors

Installation Location

Depending on your residential layout, you can fit a steam generator under the bathroom closet, under a shower bench, or in a heated attic. Although most steam showers have insulated and corrosion-resistant casings, it is better to avoid placing them in a space where there it is often exposed to human contact or water leaks.


The size of your bathroom determines the power rating of your steam generator. Typically, these generators come in power ratings ranging from 7 to 15kW. A kW steam generator ideally caters to a space that measures up to 100 to 250 cubic feet. A higher rating of 15kW covers more space, of up to 680 cubic feet.


For the steam generator to be effective, your shower needs an enclosure. With an enclosure, it curbs down the heat loss from the hot steam. However, you have to pick a suitable insulation material for the enclosure.

Some materials can easily allow some heat loss. Pick materials such as ceramic or porcelain tiles. To avoid heat loss, stay clear of materials such as granite, concrete, or marble, as they tend to be porous.

Steam Shower Head

The size of the generator determines the design of the steam showerhead and quantity. If you have limited space, a single steam showerhead is sufficient. Steam heads come in different designs and materials. You can opt for a standard stainless steel option. Alternatively, if you want to add more aesthetics and durability to your shower, you can choose a chrome or bronze brushed one.

The Verdict

Using the best steam shower generators, you can instantly transform your bathroom into a makeshift spa! After all, you can get these devices in any design you want and suit them to your specific budget. Make sure you choose the right features!
