The Headache of a Leaky Corner
A shower door leaking at the bottom corner is a proper nightmare. It starts as a tiny drip, but it never stays that way. Ignore it, and you're looking at black mould, damp floorboards, and a hefty repair bill.
Forget the confusing chatter on DIY forums. We’ve stripped away the fluff to give you professional, straight-talking strategies to fix that corner leak for good.

The Fix: Curved Shower Screen Leaks at Hinge
"Why is my shower screen still leaking at the corner even though I’ve already got a bottom seal fitted?"
The usual culprit is the "interface"—that exact spot where the shower screen seal meets the metal frame or hinge.
Because this area isn't perfectly flush, water escapes through tiny gaps in the hardware. This solution is spot on for both straight screens and glass screens fitted over a bath.

Our Pro Strategy: The Secondary Barrier
To stop a P shape bath panel corner leak dead in its tracks, you need a secondary line of defence. We highly recommend the RY3463 T-Shaped Seal or the PV29.
Crucial Fitting Tip:
You must install these on the outside of your existing seal and hardware. It’s a doddle to fit but makes all the difference.
The "Wall-Flush" Rule:
The seal must be fitted properly flush against the wall. If there's even a tiny gap, the barrier won't hold.
