Shower Screen Seal - 3-4mm Glass, Seals 18-23mm Gaps

What this seal is

A clear push-fit seal for bath screens and shower doors with 3–4mm glass. The rigid PVC U-section grips the edge of the glass on its own — no adhesive, no screws — and the flexible blade closes gaps of 18mm to 23mm, stopping water escaping onto the bathroom floor.

It is most commonly fitted along the bottom horizontal edge of a bath screen or shower door, and works just as well vertically on the glass upright to seal the gap between the glass and 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 bath or shower. Replacing it takes minutes and protects flooring, skirting and plaster.

No adhesive, no mess. The channel grips 3–4mm glass on its own — it pushes straight on and comes off again without leaving residue.

Bridges a big gap. The blade covers gaps from 18mm right up to 23mm, so even a screen sitting well clear of the bath rim seals cleanly.

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

Fitting in three steps

1. Measure. Check your glass is 3–4mm thick, measure the edge to be sealed and the gap you need to close (18–23mm).

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 seal onto the glass from below at one end and work your way along, pushing it up onto the glass as you go. Do not slide the seal along the glass, as this can damage it.

Not sure it fits?
