Collection: 5mm Shower Screen Seals

Usually no. Many replacement shower screen seals are designed to fit a 4–6mm glass range, which includes glass that measures around 5mm.

The most important thing is to choose the correct seal profile, fitting position and gap size, rather than looking for a seal labelled only as 5mm.

If your glass measures close to 5mm, you are usually looking for a 4–6mm shower screen seal. Small measuring differences are common, especially when using a ruler instead of a digital caliper.

If your measurement looks closer to thin 4mm glass, compare our 4mm shower screen seals before ordering.

If your measurement looks closer to 6mm, you can also compare our 6mm shower door seals.

Yes, and this is one of the most common reasons for buying the wrong size. Old PVC seals can stretch, harden, flatten or change shape over time.

Always measure the shower glass itself, not the old seal channel or the worn plastic strip.

It should not be too loose if the seal is designed for 4–6mm glass and the glass edge is clean and dry before fitting.

If the seal slides off, the problem is often the wrong profile shape, limescale on the glass edge, or a seal that is not actually designed for the 4–6mm range.

First confirm that your glass sits within the 4–6mm range. Then choose by fitting position: bottom seals for leaks under the door, vertical seals for side gaps, curved seals for quadrant or P-shaped screens, and magnetic seals for glass-to-glass closure.

After that, measure the gap you need to cover and compare your old seal profile with the product images.

Only if the product is clearly marked as suitable for 4–6mm glass. A seal made only for 6mm glass may not grip firmly on 5mm glass.

If your measurement is uncertain, choose a product that specifically states compatibility with 4mm, 5mm and 6mm glass.

Poor grip is usually caused by the wrong channel size, residue on the glass edge, or choosing a profile that does not match the original seal position.

Clean away limescale, soap residue and old seal marks before fitting the new seal. The glass edge should be dry before pushing the seal into place.

For water leaking under the shower door or bath screen, choose a bottom seal with a soft fin or drip rail.

Measure the gap between the bottom of the glass and the shower tray or bath rim, then choose the closest fin length, such as 12mm, 16mm, 20mm or 23mm.

Yes, many UK bath screens and lightweight shower screens sit within the 4–6mm glass range. If your bath screen glass measures around 5mm, a 4–6mm compatible profile is usually the correct starting point.

Check whether your bath screen needs a bottom seal, curved seal, vertical side seal or magnetic closing seal before ordering.
