Here’s how to measure for your new shower door (once your tile or the shower surround is installed).
1. Measure height from the top of the shower base or edge of the tub to the top of the wall or tile wall, depending on where you
want to enclose your shower.
2. Measure width from wall to wall, both at the top and bottom of the shower (as they may be different).
Tip: If the horizontal opening is out of plumb or measuring wider at the top than at the bottom, use the wider measurement for
your shower door.
