Shower Screen Seal - 4-6mm Glass, Seals 1-4mm Gaps

What this seal is

A clear replacement seal for shower doors and bath screens with 4–6mm glass. The rigid PVC U-channel simply pushes onto the edge of the glass — no adhesive required — while a soft flat flap and a small angled drip fin at its base seal small gaps of 1mm to 4mm between the glass and the bath, tray, wall or tiles.

You'll most often find this style of seal fitted horizontally along the bottom edge of a bath screen or shower door, but it works just as well vertically on the upright edge of the glass to close the gap to the wall or tiles.

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 or bath. Replacing it takes minutes and protects flooring, skirting and plaster from long-term water damage.

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

Four lengths, cut to fit. Choose the nearest length at or above your measurement and trim it down at home for a perfect edge-to-edge fit, or use our custom cutting service and it arrives ready to fit.

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

Fitting in three steps

1. Measure. Check your glass is 4–6mm thick, measure the length of the glass edge you're sealing, and measure the gap you need to close (1–4mm for this profile).

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 channel onto the edge of the glass, working along from one end — never slide it along the glass. The flap and fin close the gap with no tools, no adhesive and no drying time.
