Magnetic Shower Seals - 4-6mm Glass, 135 or 180, Spans 20mm

What this seal is

A pair of clear magnetic seals for shower doors with 4–6mm glass. Each rigid PVC U-channel pushes straight onto the edge of the glass with no adhesive at all, and carries a magnetic strip encased in white plastic to match the rest of your enclosure. When the door closes, the two strips pull together, holding it firmly shut and watertight while you shower — yet still easy to open when you're finished.

These seals are fitted vertically, most often on quadrant enclosures, though some bath screens and other doors use them too. They suit doors closing at either 135° or 180°: on sliding doors the gap can be up to 20mm when closed; on hinged or pivoting doors the gap needs to be exactly 20mm so the two magnetic strips line up properly.

Specification

Why fit this seal

Keeps the door shut and sealed. Worn magnetic seals let the door drift open mid-shower and leak along the closing edge. A fresh pair pulls the door closed and holds it there.

No adhesive, no mess. Both channels grip 4–6mm glass on their own — they slide straight on and come off again without leaving residue.

Sold as a matched pair. You get both sides of the magnetic closure in equal lengths, so the strips meet cleanly along the full height of the door.

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 glass is 4–6mm thick, note whether your door closes at 135° or 180°, and measure the closed gap — up to 20mm for sliding doors, exactly 20mm for hinged or pivoting doors.

2. Choose. Pick 2000mm or 2500mm to cover the height of your door edges, or use our custom cutting service.

3. Fit. Trim to length if needed, then push a channel onto each closing edge so the magnetic faces meet when the door shuts. No tools, no adhesive, no drying time.
