Bifold Shower Seal - 5mm T-Head, 17mm Tall, Seals 13-17mm Gaps

What this seal is

A clear bifold channel seal with a 5mm T-head and a 17mm tall body, sealing gaps of 13–17mm. The T-shaped head slides into the aluminium or plastic channel on your door frame — no adhesive needed — and the soft blade below closes the gap between the door and the tray, stopping water escaping every time you shower.

Most customers fit it horizontally under the bottom rail of a folding bath screen or shower door. Note that this profile has a slightly different blade shape to our 12–17mm version with the same T-head — check the cutaway photo against your old seal before ordering.

Choose your length

Available in 1000mm and 2000mm lengths. Order the length at or above your door width and trim it down with scissors, or use our custom cutting service and it arrives ready to fit.

Specification

Why fit this seal

Stops leaks along the bottom of the door. A worn or shrunken bifold seal lets water track under the door onto the bathroom floor — replacing it takes minutes and protects flooring and skirting from water damage.

No adhesive, no mess. The T-head simply slides into the existing channel, so there is nothing to glue and no residue when it is next replaced.

Easy like-for-like replacement. Match the 5mm T-head and 13–17mm gap range to your old seal and the new one slides straight in.

Cut to fit at home. The soft PVC cuts cleanly with a good pair of scissors, so one length covers any door up to 2000mm wide.

Fitting in three steps

1. Measure. Check the channel slot in your frame accepts a 5mm T-head, and that the gap you need to close is between 13mm and 17mm.

2. Choose. Pick the 1000mm or 2000mm length — whichever is at or above your door width.

3. Fit. Slide the old seal out, clean the channel, cut the new seal to width, then feed the T-head in at one end and slide it across.

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.
