Replacing a hinge is a measurement job, not a shopping job. The panel keeps its holes, so a replacement has to match the glass thickness, the drilling pattern and the weight the door applies - and then the door has to be adjusted so it closes against its seal rather than against the wall.
Identify the Hinge You Have
Four attributes describe any shower door hinge. The first is what it fixes to: a wall-mount hinge bolts into the wall or a wall profile, while a glass-to-glass hinge joins two panels and carries no load into the building. The second is whether it is fixed or adjustable, which decides whether the door can be re-set later. The third is the glass thickness it is cut for. The fourth is the drilling pattern - the distance between the centres of the glass holes and the diameter of those holes.
Two hinges that look identical in a photograph can differ in all four. That is why the practical route is to measure the door rather than to match a picture: hole centres, hole diameter, glass thickness, and a photograph of the hinge in place with a ruler in the frame.
Matching a Replacement to the Existing Holes
Tempered glass cannot be drilled, so the replacement has to reuse the cut-outs that exist. Measure the centre-to-centre distance of the glass holes, the hole diameter and the panel thickness, then check the hinge's rated panel weight against the door you actually have. A hinge of the right pattern but a lighter rating will deform at the pivot and the door will sag within weeks.
| Attribute | How to check it | Why it decides the fit |
|---|---|---|
| Mount type | Wall-mount or glass-to-glass | Decides the load path, not just the appearance |
| Glass thickness | Calipers on the panel edge | Leaves are cut for one thickness |
| Hole centres | Centre of one hole to centre of the other | The pattern cannot be changed afterwards |
| Panel weight | Width x height x thickness | The hinge rating has to cover it |
| Adjustable | Look for set screws or cams | Determines whether the door can be re-set |
The Wall Side Is Where Hinges Actually Fail
Most hinge problems are wall problems. A hinged door applies a live load - the panel is swung, not merely hung - so the fixings have to reach a stud, properly installed blocking, or a purpose-made wall profile. Tile over drywall with a hollow-wall plug is not a substrate for a full glass door, and a hinge that keeps losing adjustment is usually a fixing that is moving rather than a hinge that has worn out.
Where the wall cannot be opened, the options are a profile that spreads the load over a longer run, a narrower door with a fixed panel doing the structural work, or a different configuration. Framing and substrate requirements come from the adopted code, published at iccsafe.org, and wet-area methods are published by the Tile Council of North America and catalogued on the Whole Building Design Guide.
Removing and Refitting the Door
Work in this order: support the panel from below, release the wall-side hinges so the door hangs on its glass-side hardware, then lift the panel clear and lay it flat on a padded surface. Change the glass-side hinge bodies with the panel off the wall, because working in place means fighting the panel's weight while aligning a gasket.
Fit new gaskets whenever a hinge is removed and refitted: compressed gaskets are the reason a re-used hinge stays loose. Tighten to the manufacturer's stated torque, or to the point where the gasket is compressed and no further, and keep the hinge hardware together in a labelled bag if the door is going back on later. Glazing in these positions is architectural glazing under 16 CFR Part 1201.
Adjusting the Door After the Swap
A door that has dropped is usually adjustable, not broken. Open it to about 90 degrees and support it, adjust vertically first - one hinge at a time, working from the bottom up - then bring the door back through its swing and check the seal line. Adjust horizontally last, because vertical movement changes the horizontal gaps.
Two checks finish the job. The door should close against its own seal line rather than resting on the wall or the fixed panel; and the bottom sweep should bear evenly on the base across the full travel. Where the door will not hold its setting, stop adjusting and inspect the wall fixings - continuing to adjust a moving fixing simply enlarges the holes.
Hinge Count and Panel Size
Hinge count is a structural decision driven by panel mass and torque. Two hinges carry a narrow, light panel; from roughly 760 mm in 3/8 in. glass, three hinges become the norm, with the third usually at the top. Above about 900 mm of moving width, a fixed panel plus a narrower door behaves better than one wide leaf, because the torque at the top fixing grows faster than the width does.
Where the count or the panel size is the underlying problem, the plate-and-thickness theory behind it is set out in the guide to shower door hinges. This article keeps to the part in your hand: identifying it, matching it, and re-setting the door afterwards.
Finishes and What to Buy Again
Order the same finish family as the rest of the enclosure, and keep hinge and handle finishes identical on the same panel. In a wet room, Matte Black shows edge corrosion and mineral bloom earliest, Chrome and Brushed Nickel are the most forgiving, and Brushed Gold sits between them.
Hardware ratings and the test methods behind them are described by the Builders Hardware Manufacturers Association and published by ASTM International. Where a hinge has been passing water into the wall, the moisture guidance published by the EPA explains how far that has to be checked before the door goes back on.

FAQ
Can shower door hinges be replaced?
Yes, and the door usually stays in one piece. The replacement has to match the glass thickness, the hole centres and the panel weight, because tempered glass cannot be re-drilled. Measure those three, photograph the hinge with a rule in frame, and order against them rather than against a model name.
What are the replacement parts for a shower door hinge?
The hinge body is the main part, along with its gaskets, which compress and should be renewed whenever a hinge is removed. On some designs the decorative cap and the fixing screws are available separately, and on adjustable hinges the set screws or cams are the parts that let the door be re-set.
How to fix a hinged shower door that has dropped?
Support the door, adjust vertically first - bottom hinge upward - then check the seal line, then adjust horizontally. If it will not hold the adjustment, the wall fixing is moving rather than the hinge, and the repair is to re-anchor into solid backing rather than to adjust again.
What are the different types of hinges for glass shower doors?
Wall-mount and glass-to-glass, each in fixed and adjustable versions, and each rated for a panel weight range and cut for one glass thickness. Most frameless doors combine wall-mount hinges at the wall with a glass-to-glass hinge or stabiliser bar where the door meets a fixed panel.
Send the hole centres, hole diameter and glass thickness measured on your door, plus a photo of the hinge with a ruler in frame, and we will confirm the replacement set.
