Sizing Your Steam Generator

Steam sizing is more than just cubic area.  You must factor in things like wall finish (tile vs. stone), exterior walls and height to arrive at the correct "Adjusted Cubic Area".

To “size” the right generator, we start by asking for some basic information about the space you’ll be using for your steam shower.

Length x Width x Height (in feet) of the steam enclosure to determine cubic footage.
For optimum performance, ceiling height should not exceed 8'. The maximum recommended ceiling height is 10'.

a.  L x W x H = _______
"Adjusted Cubic Area" is determined by a number of factors. 

b.  Wall material:
Tile: ceramic / porcelain / glass / glass block. Add 35% _______
Natural stone: Add 100% ______

c.  Number of Exterior walls:
one wall: add 10% _____
two walls add 20% _____

d. Height: no additional factor for 8' or less:
9' height: add 15%  _____
10' height: add 30% _____

Adjusted Cubic Area = a + b + c + d
(If there window or skylight, select next larger steamer)

Example 1: 5' x '5 x 8'. Porcelain tile, one exterior wall
5x5x8=200'. Tile +70', exterior wall +20' = 290' = 7.5 kW steamer

Example 1: 4' x '5 x 9'.
Marble 4x5x9=200'. Stone +200', 9' height +30' = 430' = 10 kW steamer
