Bifold Shower Seal - 5mm T-Head, 22mm Tall, Seals 17-22mm Gaps

What this seal is

A tall clear seal for bifold and channel-fitting shower doors, with a 5mm T-head and a 22mm overall height that closes large gaps of 17–22mm. The T-shaped head slots into the aluminium or plastic channel on the door rail — no adhesive needed.

It fits horizontally along the bottom rail of a shower door or bath screen, or vertically on the glass upright. Made from soft, flexible PVC, it cuts cleanly to size with household scissors.

How to check it fits your door

Check two measurements: the slot in your channel should take a 5mm T-head (possibly slightly narrower), and the gap you need to close should be 17–22mm. This seal sits between the 17mm and 24mm versions in the same 5mm T-head family — if your gap falls between two sizes, choose the taller seal for a tighter close.

Specification

Why fit this seal

Closes large gaps other seals can't. The tall 22mm body is made for doors sitting well above the tray, stopping water escaping under the door every time you shower.

Slots straight into your existing channel. No adhesive, no screws — the T-head slides into the channel your old seal came out of.

Cuts with scissors. The soft flexible PVC trims cleanly at home for a perfect edge-to-edge fit.

UK stock, fast dispatch. Order before 2pm and your seal is dispatched the same working day.

Fitting in three steps

1. Measure. Check the channel slot takes a 5mm T-head, measure the width of the door rail, and confirm your gap is 17–22mm.

2. Choose. Pick the 1000mm or 2000mm length at or above your measurement.

3. Fit. Remove the old seal and clean the channel, trim the new seal to size, then slide the T-head along the channel until it sits flush end to end.

Not sure it fits?

Email a photo of your old seal and the gap measurement to sales@industrial-polymers.co.uk and our UK team will pick the right height from the family before you order — usually the same working day.
