White Shower Threshold Seal - Silicone-Bonded Floor Strip

What this seal is

A white threshold seal — a soft rubber strip that you bond to the floor, tray or bath edge with bathroom silicone to create a physical barrier that water simply cannot pass. It solves the awkward leaks that glass-mounted seals can't reach, keeping water within the confines of your shower or bath.

Use it on a wet room floor where the slope of the tiling doesn't carry water away efficiently; along the edge of a bath to seal the tricky section where a pivoting screen's frame meets the glass (run it the full length of the bath or just far enough to span the width of your glass); or across a shower enclosure threshold, working together with one of our over-the-glass seals to make the enclosure watertight.

Specification

Why fit this seal

Stops water dead. It forms a physical barrier the water cannot cross, protecting the bathroom floor beyond your wet room, enclosure or bath from pooling and long-term damage.

Solves the unsealable spots. Where a pivoting screen's frame meets the glass, or where a wet room floor doesn't fall towards the drain, this strip closes the route the water was taking.

Fits exactly where you need it. A bead of bathroom silicone fixes it in any position and at any length — and matching clear and black versions are available if white isn't right for your bathroom.

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. Measure the run you need to protect — the full bath edge, the enclosure threshold or the section of wet room floor.

2. Choose. Pick the nearest length at or above your measurement — 800mm, 900mm, 1400mm or 2000mm — and cut down at home, or use our custom cutting service.

3. Fit. Clean and dry the surface, run a bead of bathroom silicone along the underside of the seal, press it into position and allow the silicone to cure before showering.
