To determine the size and quantity of wedi Building Panels you will
need for your shower, please follow the steps outlined below:
First, you must calculate the total area of the shower walls. To
do this, measure the area of each shower wall by multiplying the
length of the wall by the height. The height of each wall will be
determined based on how high you plan to install the tile. Next, add
the calculated square footage of each wall together to determine
the combined sum of all the shower walls. Account for about 15%
extra square feet of building panel for any waste cuts by multiplying
the combined area of all shower walls by 1.15.
Next, divide the total area of the shower walls by the square foot
area of the wedi building panels you plan to use (eg: 4x5 ft. building
panel = 20 square feet). A total shower wall area of 115 square feet
divided by 20 square feet per building panel gives us a total of 5.75
building panels. Remember to always round up to the next whole
building panel.
Tip: choose the wedi building panel sizes that will keep your
installation process fast, efcient, and eliminate unnecessary seams and waste. For example: a shower wall that is 5 feet wide
and 8 feet high can be covered with TWO of the 4 x 5 foot wedi building panels, whereas that same wall would require THREE
of the 3 x 5 foot building panels, resulting in an extra seam and wasted product.
Please note, wedi building panels must extend to the outside edge of the shower curb element for proper water-proong, so
be sure to account for the added dimensions of the shower curb to your shower side walls when determining the size of the
building panels. For example, a 3 x 5 foot building panel is NOT a good option for a 36 inch shower wall where the curb extends
beyond the 36 inch shower base, because you will have to install the panel horizontally to reach the outside edge of the curb,
resulting in unnecessary waste.
In general, the larger building panels are the more economic option. The traditional 3 x 5 foot building panels are most often
used for tub surrounds where the true dimensions of the tub are closer to 32 x 60 inches.
Please note: in steam shower projects you will also need enough Vapor 85 building panels to cover the ceiling (calculate square
feet as you did for walls, and choose the largest panels possible for faster and cleaner installation with fewer seams to treat
overhead).
