Enter the distance (ft) into the Calculator. The calculator will evaluate the Shower Pan Slope. 

Shower Pan Slope Formula

SPS = D /4


  • SPS is the Shower Pan Slope (ft/ft)
  • D is the distance (ft)

To calculate Shower Pan Slope, divide the total length of the shower by 4.

How to Calculate Shower Pan Slope?

The following steps outline how to calculate the Shower Pan Slope.

  1. First, determine the distance (ft). 
  2. Next, gather the formula from above = SPS = D /4.
  3. Finally, calculate the Shower Pan Slope.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
