Shower Door Size Finder
Measure your finished opening at the top, middle and bottom, then enter the narrowest of the three. We show every door whose adjustable range covers that width, plus the checks that still apply.
How to measure
- Measure wall to wall at three heights — just above the threshold, at about 40 in., and near the top of where the door will sit.
- Use the narrowest figure. A door sized to the widest measurement will not go in.
- Note the difference between the three. More than about 1/2 in. means the opening is out of plumb, and a frameless door is the least forgiving choice.
- Measure the height from the threshold or tub deck to where the door will finish. 72 in. and 76 in. are both common and are not interchangeable.
These results are a fit shortlist, not an installation guarantee. Always confirm the manufacturer's stated tolerance on the product page before ordering, and check threshold depth and wall construction.
