Shower Screen Seal - 4-6mm Glass, Seals 10-13mm Gaps

What this seal is

A clear replacement seal for shower doors and bath screens with 4–6mm glass. The rigid PVC U-section pushes onto the edge of the glass — no adhesive needed — and the flexible fin closes gaps of 10mm to 13mm, stopping water escaping every time you shower.

It is most often fitted horizontally along the bottom edge of a bath screen or shower door, and works just as well vertically on the upright of the glass to seal against the tiles or wall.

Specification

Why fit this seal

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

No adhesive, no mess. The channel grips 4–6mm glass on its own — it slides straight on and can be removed again without leaving residue on the glass.

Barely visible once fitted. The clear PVC lets your glass do the talking while the flexible fin quietly closes a 10–13mm gap.

UK stock, fast dispatch. Held in stock in the UK and dispatched same day when you order before 2pm.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick, measure the length of the edge to be sealed, and measure the gap you need to close (10–13mm for this seal).

2. Choose. Pick the nearest length at or above your measurement — 800mm, 900mm, 1400mm or 2000mm — or use our custom cutting service.

3. Fit. Trim to length if needed, then push the channel onto the edge of the glass so the fin faces the gap. No tools, no adhesive, no drying time.
