Shower Screen Seal - 4-6mm Glass, Straight Fin 11-16mm Gaps

What this seal is

A clear replacement seal for shower and bath screens with 4mm, 5mm or 6mm glass. The rigid PVC U-section pushes straight onto the edge of the glass — no additional adhesive needed — and seals gaps of 11mm to 16mm between the glass and your bath, tray, tiles or wall.

Seals like this are most commonly found along the bottom horizontal edge of a bath screen or shower door, and work just as well vertically on the upright of the glass to seal against the tiles or wall.

Choose your length

Measure the edge of the glass you are sealing and pick the nearest length at or above it — 800mm, 900mm, 1400mm or 2000mm. If your measurement sits between two lengths, choose the longer one and trim it down, or add our custom cutting service and it arrives ready to fit.

Specification

Why fit this seal

Stops leaks and protects your bathroom. A worn, discoloured or missing seal is the most common cause of water pooling outside the shower — replacing it takes minutes and protects flooring, skirting and plaster from long-term damage.

No adhesive, no mess. The U-section grips 4–6mm glass on its own, so it pushes straight on and can be removed later without leaving residue on the glass.

Nearly invisible once fitted. The clear PVC blends into the glass, keeping the clean look of your enclosure while sealing an 11–16mm gap.

Cut to fit at home. Order the next length up and trim it down for a perfect edge-to-edge fit, or use our custom cutting service.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick and the gap you need to close is 11–16mm, then measure the edge you are sealing.

2. Choose. Pick the nearest length at or above your measurement.

3. Fit. Remove the old seal, clean the glass edge, trim the new seal to size and push the U-section onto the edge of the glass. No tools, no adhesive, no drying time.
