Black Shower Screen Seal - 4-6mm Glass, Seals 3-7mm Gaps

What this seal is

A black replacement shower screen seal for 4–6mm glass, sealing gaps of 3mm to 7mm. The high-quality rigid PVC U-section pushes straight onto the edge of the glass with no additional adhesive, while a soft flexible bubble along the bottom compresses against the tray, tiles or wall to give a watertight seal.

This profile is most commonly fitted along the bottom horizontal edge of a bath screen or shower door, and works just as well vertically on the upright of the glass to seal against the wall or tiles. It is a straight seal, designed for straight glass only.

Choose your length

Available in 800mm, 900mm, 1400mm, 2000mm or 2500mm lengths. Measure the edge of glass you need to cover and pick the nearest length at or above it — the seal is easily cut down to size at home, or use our custom cutting service and it arrives ready to fit.

Specification

Why fit this seal

Stops leaks and protects your bathroom. A worn or perished bubble seal lets water dribble onto the floor every time you shower — replacing it takes minutes and protects flooring, skirting and plaster from long-term water damage.

No adhesive, no mess. The rigid PVC channel grips 4–6mm glass on its own, so there is nothing to stick, cure or clean up — and it can be removed without leaving residue.

Soft bubble, tight seal. The flexible bubble compresses against the tray or tiles across the whole 3–7mm range, so small variations in the gap along the glass are absorbed without leaving daylight.

Discreet black finish. The black profile suits dark-framed and matt-black shower enclosures, giving a neat, deliberate look rather than an obvious repair.

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick, measure the gap you need to close (3–7mm for this profile) and the length of the glass edge.

2. Choose. Pick the nearest length at or above your measurement — or add custom cutting and we'll trim it for you.

3. Fit. Trim to length if needed, then push the seal onto the glass starting at one end and work your way along, pressing it on as you go — don't slide it along the glass, as this can damage the seal.

Not sure it fits?
