Shower Screen Seal - 10-12mm Glass, Seals 5-10mm Gaps

What this seal is

A clear straight-fin shower screen seal for thick 10–12mm glass, sealing gaps of 5mm to 10mm. The rigid PVC U-channel — 14mm tall, with a 10mm mouth widening to 12mm at the base and internal gripping nibs — pushes straight onto the edge of the glass and grips on its own with no adhesive, no screws and no drilling, while the straight 10mm fin below closes the gap between the glass and the tray, bath, wall or tiles.

It is most often fitted along the bottom horizontal edge of a bath screen or shower door, and works just as well vertically on the upright of the glass to seal against the wall or tiles. Suitable for straight glass only.

Specification

Why fit this seal

Stops leaks instantly. A worn, discoloured or missing seal along the bottom or upright of the glass is the most common cause of water pooling outside the shower. Replacing it takes minutes and protects flooring, skirting and plaster from water damage.

Made for heavyweight glass. Frameless enclosures with 10–12mm panels need a wider channel than standard seals offer — this one is sized to grip thick glass comfortably and securely.

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

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

Fitting in three steps

1. Measure. Check your glass is 10–12mm thick, measure the edge you are sealing, and measure the gap you need to close — it should be between 5mm and 10mm.

2. Choose. Pick the nearest length at or above your measurement, or have us cut it to size for you.

3. Fit. Trim to length if needed, then push the U-channel squarely onto the edge of the glass so the fin closes the gap. No tools, no adhesive, no drying time. Never slide the seal along the glass — this can damage it.

Not sure it fits?

Email a photo of your old seal or your measurements to sales@industrial-polymers.co.uk and our UK team will confirm the right profile and length before you order — usually the same working day.
