Measure the length, width, and height in feet of the current steam shower or bathtub room.
Example; L:7 x W:5 x H:8 = 280 Cubic feet x 2 to get complete cubic measurement
Note : Multiplying the cubic feet by two is done to account for heat loss due to the room having natural stone such as
granite or marble, exterior walls, ceiling height exceeding 8 feet, ceramic tile, or glass walls.
