Black Bifold Shower Seal - 4.5mm T-Head, 19mm Tall, Seals 14-19mm Gaps

What this seal is

A black bifold shower door seal for larger gaps. The slim 4.5mm T-head slides into the channel in the door frame, and the tall 19mm body closes gaps of 14–19mm between the door and the tray, bath or wall.

Fit it horizontally under the bottom rail of a bath screen or shower door, or vertically on the glass upright. No adhesive is needed — the T-head is held by the channel itself — and the solid black colour sits invisibly against black-framed enclosures.

Choose your length

Available in 1000mm or 2000mm lengths, each with a custom cut option. Pick the length at or just above your door width and trim to size — the soft PVC cuts with scissors.

Specification

Why fit this seal

Closes big gaps other seals cannot. At 19mm tall, this profile reaches across 14–19mm gaps that leave standard-height seals dripping — protecting your flooring and skirting from escaping water.

Made for black enclosures. The solid black PVC matches black and dark-framed doors instead of standing out against them.

No adhesive, no mess. The T-head simply slides into the existing channel — and slides out again when it eventually needs replacing.

Cuts with scissors. Soft flexible PVC trims to an exact fit at home in seconds.

Fitting in three steps

1. Measure. Check the slot in your channel is around 4.5mm wide and the gap you need to close is between 14mm and 19mm.

2. Choose. Pick 1000mm or 2000mm — whichever is at or above your door width — or add the custom cut option.

3. Fit. Remove the old seal, clean the channel, cut the new seal to width, then feed the T-head in at one end and slide it along until flush.
