Shower Screen Seal - 4-6mm Glass, Seals 4-8mm Gaps

What this seal is

A clear shower screen seal for 4–6mm glass that closes gaps of 4mm to 8mm. The rigid PVC U-section pushes straight onto the edge of the glass — no adhesive, screws or drilling — and the flexible section bridges the gap between your screen and the bath, tray, tiles or wall, stopping water escaping every time you shower.

It's most commonly fitted along the bottom horizontal edge of a bath screen or shower door, but works just as well vertically on the upright of the glass, sealing against tiles or a wall.

Choose your length

This seal comes in 800mm, 900mm, 1400mm or 2000mm lengths. Pick the length at or above the edge you're sealing — it cuts down easily at home, or use our custom cutting service and it arrives ready to fit.

Why fit this seal

Stops leaks instantly. A worn, discoloured or missing screen 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.

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

Made for thinner glass. Bath screens and lighter enclosures with 4–6mm panels need a channel sized to match — this one grips snugly and seals gaps of 4mm to 8mm, with clear PVC that's barely visible once fitted.

Cut to fit at home. Order the next length up and trim it down for a perfect edge-to-edge 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 of the glass, and measure the gap you need to close — it should sit between 4mm and 8mm.

2. Choose. Pick the nearest length at or above your measurement.

3. Fit. Trim to length if needed, then push the channel onto the edge of the glass so the seal faces the gap. Done — no tools, no adhesive, no drying time.
