Measurement Guide
Choosing the right Shower Door is as easy as 1-2-3. 
But before you customize your dream door, you need 
to make sure you have the correct measurements.
•  Identify Vertical and Horizontal Openings  
Height (A) and Widths (B). 
•  Vertical Opening 
Measure from the top of the tub apron or the top 
of the threshold up to the top of the acrylic (or tile) 
surround wall. 
•  Horizontal Opening 
Measure width of opening at the top and the 
bottom of the enclosure.

**Disclaimers
• For ceramic tile application, use the top of the tile 
for the maximum door height.
• In older homes the opening at the top is often wider 
than the bottom due to an out-of-plumb condition.
• NOTE: All Delta Shower Doors are designed to 
accommodate out-of-plumb conditions totaling 3/8”.
