If your shower screen is leaking at the hinge, don't worry — you're not alone. This is easily the most common (and proper annoying) leak we see in frameless showers.
The good news? You don't need a whole new screen. A high-quality shower screen seal will usually do the trick!
In this tutorial, we’ll show you a simple DIY fix to stop the leak for good. Let's get stuck in!
Confirm Your Leak Type
Leaky hinges usually fall into two camps, and each requires a different fix:
| Leak Type | Location | Solution |
|---|---|---|
| Bottom Corner Leak | Base of the door, near the bottom hinge. | Install a Threshold Strip. |
| Vertical Side Leak | Along the vertical glass edge by the hinge gap. | Trim and fit an H-Type Seal. |
I. Type One: Bottom Hinge & Corner Leak
This usually happens when the bottom seal leaves a tiny gap near the hinge fitting.
Often, a simple threshold strip is the missing piece to divert water back into the tray, even if your door isn't faulty.
Pro Tip: Check out our definitive guide on how to stop water escaping from the corner.
The "Pivot Hinge" Obstruction
Is your pivot hinge blocking the seal like the photo below? When the door axis gets in the way, a standard seal can't cover the gap properly.
The Solution: You'll need to custom-trim the seal to "wrap" around the hinge. Since this intricate trimming process can be tricky, we've filmed a dedicated video guide to help you get a water-tight finish.

II. Type Two: Vertical Side Hinge Leak
To block water escaping from the side, we use a custom-trimmed H-type seal strip.
Essential Tools
- Marker pen & Measuring tape
- H-shape seal (Pick the one that matches your glass)
- Sharp garden pruning shears
Quick Note: You must use an H-type—other shapes usually can't clear the hinge mechanism.
Visual Step-by-Step
Prefer to watch? Here’s exactly how to tackle that vertical hinge leak:
Measurement & Fitting
If you have two hinges, cut the seal into three sections to fill the gaps between the hinge plates.
Press the trimmed sections firmly onto the glass. Crucial: Ensure the flexible long fin points inwards to block the water. Job done!
Trade Secrets for a Perfect Fit
- Sizing: Choose a seal slightly thicker than your glass (e.g., a 6-8mm seal for 6mm glass) for better coverage.
- Warmth: If the seal is stiff, soak it in warm water (under 70°C) to make it more pliable.
🛑 Professional Warning: Avoid using soapy water or oils! They act as a food source for mould in the long run.
