Vertical Shower Screen Seal - 8-10mm Glass - Fin Width of 10mm, 15mm, 20mm or 25mm

What this seal is

A clear vertical seal for shower screens and doors with 8–10mm glass. The rigid PVC U-section pushes straight onto the edge of the glass — no adhesive required — and the soft side fin closes the gap between your glass and the adjacent panel, wall or tiles, stopping water escaping every time you shower.

This profile is most often used vertically, typically in conjunction with another similar-shaped seal, and it can also be fitted along the bottom horizontal edge of a bath screen or shower door.

Choose your fin width

The soft fin is available in widths of 10mm, 15mm, 20mm or 25mm. Measure the gap you need to close and pick the fin width that covers it — if your gap sits between two sizes, choose the larger fin, as the flexible blade compresses to give a tighter seal.

Specification

Why fit this seal

Stops leaks and protects your bathroom. A worn or missing vertical seal lets water escape past the edge of the door — replacing it takes minutes and protects flooring, skirting and plaster from water damage.

No adhesive, no mess. The U-section grips 8–10mm glass on its own, so it pushes straight on and comes off cleanly whenever it needs replacing.

Four fin widths, one profile. Whether your gap needs a 10mm or a 25mm fin, the same clip-on channel closes it neatly — and the clear PVC is barely visible once fitted.

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

Fitting in three steps

1. Measure. Check your glass is 8–10mm thick, measure the edge you are sealing, and measure the gap you need to close.

2. Choose. Pick the fin width that covers your gap, and the nearest length at or above your measurement.

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