How to Measure for an Arizona Shower Door
Door Only
One of the first things to consider before you start to measure is to determine where on the curb (base or pan) that the center line of your door will sit. For example if your curb is 4" wide and you want your door to line up in the center of the curb, your center line will be at 2". View Example 1.0 for visual representation.
If you would like the center line to be closer to the outside of the shower enclosure, measure one end of the curb to the distance that you would like and then measure the same distance on the opposite side. For example, with a 4" wide curb you could measure 1" in from the left outside and then do the same for the right outside side. View Example 1.1 for visual representation. Do the same for the inside if the door is to be placed closer to the inside of the enclosure. Next measure the length of the curb from the left center line to the right center line. View Example 1.2 for visual example. The next step is to determine the height of the shower door. Arizona Shower Door recommends using one of the Stock heights for a door only. For a semi-frameless Door with a metal bottom (CDM, CDMP, and CDFMP) or (MP a semi-Frameless Door with a Polycarbonate bottom) use one of the following heights: 66 3/16" or 72 3/16". The (R and RP A semi-Frameless Door with a Polycarbonate bottom) use one of the following heights: 65 9/16" or 72 9/16". For a fully Framed Door (FD) 
use one of the following heights: 67 5/16" or 73 5/16". 
View Example 1.3 for visual example. If you wish to have a different height the cost will increase because of custom sizes. Please talk with a sales associate to determine what is available to you. To ensure that the shower door is built correctly see the "Things to Consider" section of this page.
Door with 180° Inline
For curb and centerline measurements refer to "Door Only" instructions. The next step is to determine the width of the door opening and the height of the shower enclosure. Arizona Shower Door recommends using one of the Stock heights: 69" or 75". If you wish to have a different overall height the cost will increase because of custom sizes. The Door width can range from 22" – 36". Arizona Shower Door recommends a 28"- 30" door width as this is a stock width that will fit the function and overall look of a Door Inline Enclosure. Please talk with a sales associate to determine what is available to you. To ensure that the shower door is built correctly see the "Things to Consider" section of this page.
Door with a 90°/135°/custom angle return
For instructions on how to determine centerline measurements refer to "Door Only" instructions. After determining where the centerline of your shower will be on the tile you will need to determine where the centerline is at the point of your return. View Figure 3.0 for visual example. 
The easiest way to do this is measure a few inches in from the point of return, and mark the centerline. Do the same thing for the center line closest to the nearest wall along the same curb. View Figure 3.1 for visual example. Use a straight edge or a level and align the two centerline marks with the edge of the level or straight edge. Using a wax pencil, draw a line that will cross the point of the return. View Figure 3.2 for visual example. Do the same thing for return side of the shower. The point at which both drawn lines intersect is the centerline point of the return View Figure 3.3 for visual example. 
The next step is to determine the height of the shower enclosure. To do this simply measure from the curb to the top of the shower head, and decide on a height that you like. Arizona Shower Door recommends using one of the Stock heights: 69" or 75" and should fit most designs. View Figure 3.0 for visual example. 
If you wish to have a different overall height the cost will increase because of custom sizes. Please talk with a sales associate to determine what is available to you. To ensure that the shower door is built correctly see the "Things to Consider" section of this page.
Things to Consider
Wall Outages:
While measuring for a shower enclosure you need to determine how far "Out-of-Square" the walls and curb are. To accomplish this you need to use a level. The longer the level the more accurate the outage will be. We recommended using a 72" level, but a 48" (4′) level will work for most applications. Start by placing the level against the wall where the centerline of the glass will sit. View example 1.3 for a visual representation. If the bubble indicates that you are not level place shims (wood or plastic) in between the wall and the level until the bubble indicates that is level. Then measure the distance between the wall and level, this will give you the outage for that wall. View Example 2.0 for a visual representation. Along with the outage, the "lean" of the outage needs to be determined. The wall will lean "IN" or "OUT". View example 2.0 for a visual representation.
