Shower Screen Seal - 4-6mm Glass, Bulb Seal 7-12mm Gaps

What this seal is

A clear shower screen seal for 4–6mm glass, sealing gaps of 7mm to 12mm. The rigid PVC U section pushes straight onto the edge of the glass and grips on its own — no adhesive, no screws, no drilling — while the soft flexible bubble along the bottom compresses against the tray, bath, wall or tiles to close the gap.

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.

Soft bubble, gentle contact. The flexible bubble compresses against the tray or bath, closing gaps from 7mm to 12mm while letting the door move freely.

No adhesive, no mess. The channel is designed to comfortably grip 4–6mm glass on its own — it slides straight on and can be removed 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 4–6mm thick, measure the edge you are sealing, and measure the gap you need to close — it should be between 7mm and 12mm.

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 channel onto the edge of the glass so the bubble sits against the tray or wall. No tools, no adhesive, no drying time.
