Bifold Shower Seal - 8mm T-Head, 20mm Tall, Seals 15-20mm Gaps

What this seal is

A clear channel seal for bifold shower doors and bath screens — the tallest fully-soft 8mm T-head we stock. The 8mm T-head slots into the aluminium or plastic channel in the door frame with no adhesive, and the 20mm-tall soft body closes gaps of 15–20mm.

It fits horizontally under the bottom rail of the door, or vertically between the glass and the wall. If your gap is smaller, our other 8mm T-head profiles cover gaps from 2–4mm up to 8–13mm.

Specification

Why fit this seal

Closes big gaps under bifold doors. The 20mm body seals gaps of 15–20mm that shorter blades cannot reach, keeping water off the bathroom floor and protecting flooring and skirting.

No adhesive, no mess. The T-head slides into the existing channel in the frame and stays put — nothing to glue, nothing to drill.

Cut to fit at home. The soft PVC cuts cleanly with ordinary scissors, so trimming to the exact width of your door takes seconds — or use our custom cutting service.

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

Fitting in three steps

1. Measure. Check your channel slot takes an 8mm T-head, measure the gap beneath the door (15–20mm) and the width of the run.

2. Choose. Pick the 1000mm or 2000mm length at or above your measurement, or use our custom cutting service.

3. Fit. Remove the old seal and clean the channel, cut the new seal to length, then slide the T-head along the channel until it is fully seated.

Not sure it fits?

Email a photo of your old seal or your measurements to sales@industrial-polymers.co.uk and our UK team will confirm the right profile and size before you order — usually the same working day.
