Tapered Shower Seal for Uneven Gaps - 4-6mm Glass, 900mm

What this seal is

A clear tapered seal (ref SEAL104) for shower and bath screens with 4–6mm glass. The rigid PVC U-section simply pushes onto the bottom edge of the glass — no adhesive required — while the soft flexible fin underneath is tapered in height, closing an uneven gap between the glass and the top of the bath or shower tray. Please refer to the product diagrams for the exact fin sizes.

If your screen sits closer to the tray at one end than the other, a standard straight-fin seal will either drag or leave a gap. This tapered profile follows the slope, giving a consistent seal along the full width of the glass.

Which taper do I need?

Measure the gap between the glass and the tray at both ends of the screen. In most cases we recommend a seal with a fin between 2–5mm bigger than the gap you need to seal — the flexible fin compresses for a tight, watertight fit. Our tapered seals come in a number of sizes to suit almost any gap.

Specification

Why fit this seal

Seals uneven gaps properly. A sloping gap under the glass is a common cause of persistent leaks — the tapered fin closes it along its whole length, protecting flooring, skirting and plaster from water damage.

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

Cut to fit at home. The 900mm length trims down to your screen width, 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 and measure the gap at both ends of the screen to confirm the taper suits.

2. Choose. Pick a fin around 2–5mm larger than your gap, and trim the 900mm length to your screen width if needed.

3. Fit. Push the channel onto the bottom edge of the glass so the tapered fin sits against the bath or tray. No adhesive, no drying time.
