Shower Screen Seal - 4-6mm Glass, 25mm Fin & Flick Fin

What this seal is

A clear replacement seal for shower doors and bath screens with 4–6mm glass. The rigid PVC U-channel pushes straight onto the edge of the glass — no adhesive, no screws, no drilling — and seals large gaps of 20mm to 25mm between the glass and the tray, tiles or wall, stopping water escaping every time you shower.

You will most often find this profile along the bottom horizontal edge of a bath screen or shower door, but it works just as well fitted vertically on the upright of the glass to seal against the tiles or wall.

Specification

Why fit this seal

Stops leaks and protects floors. A worn, discoloured or missing bottom 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 water damage.

Closes a big gap neatly. With a 20–25mm sealing range, this profile bridges the kind of gap most standard seals cannot reach — ideal where a door was hung high or a tray sits low.

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.

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, measure the edge you need to seal and confirm the gap to close is between 20mm and 25mm.

2. Choose. Pick the nearest length at or above your measurement — 800mm, 900mm, 1400mm or 2000mm.

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