So, what exactly is a center line measurement and why do we need it?
Put simply, a center line measurement is just the measurement along the center of the curb or where the door will sit on the curb. The image below shows 3 measurements on the curb along the center line for the neo enclosure and 2 measurements for the corner shower.
With fiber glass shower stalls we either already know this measurement based off our knowledge base or the manufacturers specification sheets. Our handy sizing guide has a lot of this information and easily links you to the model of door that will fit. Easy!
Sometimes though, and often with a shower base, it will be installed into a space and then finished using a backer board, mortar, and finally tile. In this case, it's important to get center line measurements after the walls are complete as it will vary based on the materials chosen.
How exact do you need to be? It depends on the door model and how much opening you have to work with. Sliding door styles like the 350D have lots of overlap in the middle which means they have a much bigger adjustment range (4" or so). A pivot door and inline from the 391C/391CV give about a 1-1/4" overall adjustment range. 10mm frameless pivot doors are precise and need exact measurements. Finally, small single door openings need to be quite exact as well unless buying smaller than anticipated and purchasing our 1" filler piece.
