Steam Shower Sizing Guide.

If you are considering installing a steam shower generator, you need to know the proper size of generator to buy for your application. There are a range of variables that can affect the correct sizing from dimensions to the material of the shower. Below, we will help guide you to choosing the perfect generator for your shower! *Please note that every manufacturer is different and for the most clear estimation, check their website or spec sheets for their own calculations.*

Finding Cubic Footage.

To find your cubic footage, measure length, width, and height. You then multiply those numbers to find your base cubic footage which we will then adjust for other elements. 

 

Example: 5L x 5W x 8H = 200 Cu. Ft.

Adjusting The Cubic Footage (If Required).

Adjusting cubic footage is important for certain brands such as Mr. Steam as 2 additional elements can effect how well your steam shower works and creates a consistently steamy environment.

Shower Material: As laid out in our other blog "Guidelines To Follow When Building a Steam Shower", natural stone *may* require an adjustment to cubic footage as it may not heat effectively with a smaller generator. This also applies to marble applications. The height of the shower is also an important factor as we will mention below.

Material:

*Depending on manufacturer* Natural stone, natural marble, concrete, glass block, or slate showers: multiply Cu. Ft. by 2.0

Thin set ceramic tile, acrylic, or fiberglass: no multiplication needed.

Other material: Contact us and we can get a proper adjustment for you.

 

Continuing example: Natural stone 200 Cu. Ft. = 200 x 2 = 400 Cu. Ft.

Ceiling Height:

It is recommended to not go above 10ft ceiling height in a steam shower application as the steam can rise and leave the lower part of the shower with an inconsistent temperature. Ideally, 8ft is the sweet spot for steam shower height. Applications of 9ft and 10ft can require additional steam generator power.

For 9 foot ceiling: Multiply by 1.1

For 10 foot ceiling: Multiply by 1.3

With ThermaSol, each additional foot in ceiling height over 8 feet, go up a generator size up to 10 ft.

Continuing example: Since the shower is 5 x 5 x 8, there is no need to multiply to account for additional ceiling height.
