Universal Soft Corner Piece for Shower Seals - 4-6mm Glass
What this corner piece is
A soft, flexible clear corner piece that eliminates leaks at the point where your glass screens meet — the spot straight seals cannot reach. It pushes directly onto 4–6mm thick glass with no silicone or adhesive, and your straight seals then push into either side to create one continuous, watertight barrier around the corner.
Unlike traditional rigid corner pieces that need an exact height match, this is a universal problem solver: the soft fins seal gaps up to 23mm high and can be trimmed down for smaller gaps, so one piece suits a wide range of enclosures.

Why fit this corner piece
Seals the leak-prone corner. Where two screens meet, straight seals leave a gap that lets water track onto the floor. This piece bridges the corner and joins your two straight seals into one continuous barrier.
Universal fit. With fins sealing gaps up to 23mm high, there is no need to hunt for an exact height match — and non-standard gaps of 16mm or less are handled by simply trimming the soft bottom fins to size.
No silicone, no mess. It pushes straight onto the glass, and once the straight seals are pushed into either side they hold the corner piece firmly in place.
Discreet clear finish. Designed to blend in with your glass and existing seals — see the gallery images.
Fitting in three steps
1. Measure. Check your glass is 4–6mm thick and measure the gap height at the corner between the glass and the bath or tray.
2. Trim. If your gap is smaller than the fins — for example 16mm or less — trim the soft bottom fins to size with a Stanley knife or scissors.
3. Fit. Push the corner piece onto the glass at the corner, then push your straight seals into either side. They lock the corner piece in place — no silicone or adhesive needed.
