Shower Screen Seal - 8-10mm Glass, Rigid Fin & 15mm Bulb

What this seal is

A clear replacement seal for shower doors and bath screens fitted with 8–10mm glass. The rigid PVC U-channel — 13mm tall, with an 8mm mouth widening to 10mm at the base and internal gripping nibs — pushes onto the edge of the glass with no adhesive, gripping glass measuring 8mm, 9mm or 10mm thick. A rigid 10mm deflector fin angles up from the channel mouth to throw running water back into the shower, and along the bottom runs a soft flexible 15mm bubble that compresses against the tray, bath or wall to close gaps of 10mm to 15mm.

This profile is most often fitted along the bottom horizontal edge of a bath screen or shower door, but it works just as well vertically on the upright of the glass, sealing the gap between the glass and the tiles or wall.

Specification

Why fit this seal

Stops leaks and protects your bathroom. A worn, discoloured or missing 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.

Soft bubble, tight seal. The flexible bubble along the bottom compresses to follow the tray or bath rim, keeping full contact across gaps of 10–15mm, while the rigid deflector fin sheds running water back into the tray.

No adhesive, no mess. The rigid U-section grips 8–10mm glass on its own — it pushes 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 8–10mm thick, measure the edge you need to seal, and check the gap you are closing sits between 10mm and 15mm.

2. Choose. Pick the nearest length at or above your measurement — 800mm, 900mm, 1400mm or 2000mm — or add custom cutting and we cut it to size before dispatch.

3. Fit. Trim to length if needed, then push the U-channel squarely onto the edge of the glass with the deflector fin facing into the shower and the bubble against the surface you are sealing. No tools, no adhesive, no drying time. Never slide the seal along the glass — this can damage it.
