Try Our Virtual Spa System --- Ever wondered how to size a steam shower generator?  It's an important question. Like Goldilocks’ disappointment with mismatched housewares, homeowners purchasing a home steam shower can be similarly dismayed if the [steam shower generator](https://www.mrsteam.com/products/generators/) is sized too small or too big. The former fails to satisfy, while the latter needlessly wastes energy. So how to get things… “just right?” The most critical consideration is to make certain to ***include materials, as well as dimensions***, in your generator-sizing calculations. ### Why do materials - as well as dimensions - affect Steam Shower Generator Size? The reason for including materials is that the type of building materials used to construct your steam shower can have a profound effect on its performance and, ultimately, your satisfaction. As hot steam enters a steam shower, it reacts with a room’s walls, ceiling, and ambient temperature, resulting in a thick, foggy, rejuvenating steam. Much like a sponge, room materials can absorb steam, and if the steam shower generator is too small, it will yield only cool mist, rather than relaxing heat. It is for this very reason that factors such as building materials, lofty ceiling heights (over 96"), and personal preferences must be considered along with steam shower volume (width x length x height) when selecting a properly sized steam generator. For example, if your steam enclosure is constructed from a non-porous material, such as acrylic, fiberglass or some other formed plastic, you likely will require a smaller generator than suggested by standard sizing guidelines, which are typically based on ceramic tile. Likewise, use of porous materials, such as natural stone, marble, concrete, and glass block can dramatically increase the size of the generator required.
