Vertical Shower Seal - 4-6mm Glass, Soft 20mm Side Fin

What this seal is

A clear vertical seal for shower doors and bath screens with 4–6mm glass. The rigid PVC U-channel pushes straight onto the upright edge of the glass — no adhesive, no screws, no drilling — and closes the gap between the glass and the adjacent tiles or wall, stopping water escaping down the side of the screen every time you shower.

Although this profile is normally fitted vertically, it can also be used horizontally, so the same seal covers most edges of a straight-glass door or screen.

Specification

Why fit this seal

Stops leaks and protects floors. A worn, discoloured or missing vertical seal lets water track down the edge of the glass and pool outside the shower. Replacing it takes minutes and protects flooring, skirting and plaster from long-term water damage.

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

Vertical or horizontal. Fit it up the side of the screen against the wall or tiles, or run it along another straight edge — the same profile does both.

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 4–6mm thick and measure the height of the edge you need to seal.

2. Choose. Pick the nearest length at or above your measurement — 900mm, 1400mm or 2000mm.

3. Fit. Trim to length if needed, then push the channel onto the upright edge of the glass so the seal closes the gap to the wall or tiles. No tools, no adhesive, no drying time.
