Bifold Shower Seal - 8mm T-Head, 13mm Tall, Seals 8-13mm Gaps

What this seal is

A clear channel seal for bifold shower doors and bath screens with an 8mm T-head and a 13mm overall height, closing gaps of 8mm to 13mm. The T-head simply slots into the aluminium or plastic channel on your door — no adhesive at all — and the soft blade seals down to the tray or bath. It also fits vertically on glass uprights against tiles or a wall.

This is the tallest of the three 8mm T-head profiles we stock (the others are 9mm and 10mm tall), so measure the gap under your door first: if it's 8–13mm, this is the one.

Which height do I need?

All three profiles share the same 8mm T-head — only the height differs. Measure the gap between the bottom of your door and the tray or bath: choose the 9mm or 10mm version for smaller gaps, and this 13mm version for gaps of 8–13mm. If your measurement sits between profiles, choose the taller one — the soft blade compresses for a tighter seal.

Specification

Why fit this seal

Stops leaks under the door. A shrunken or perished channel seal lets water stream out under a bifold door every shower. A fresh blade sized to your gap keeps it in the tray and off your floor.

No-mess fitting. The T-head slides into your door's existing channel — no adhesive, no tools beyond a pair of scissors.

Easy like-for-like replacement. Match the 8mm T-head and the 13mm height to your old seal and the new one drops straight into place in minutes.

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

Fitting in three steps

1. Measure. Check your channel takes an 8mm T-head, measure the gap under the door (8–13mm) and the width of the door.

2. Choose. Pick 1000mm or 2000mm to cover your door width, or use our custom cutting service.

3. Fit. Slide out the old seal, clean the channel, cut the new seal to width, then feed the T-head into the channel and slide it along until seated end to end.

Not sure it fits?

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