(i.e., Your gap ≤ Seal's rated gap)

Magnetic Shower Door Seal FAQ
  • Why are your Magnetic Seals only 4-5mm when others offer 4-6mm?

    This is about precision and durability! Standard 4-6mm magnetic seals are often too loose on a true 6mm door. Our 4-5mm magnetic seals are engineered for a tighter, lasting grip on 4mm to 5mm glass.

  • What is the correct magnetic seal for 6mm shower doors?

    The ideal seal for your 6mm shower door is our 6-8mm magnetic seal series. It ensures a perfect watertight seal and strong magnetic connection for 6mm glass.

  • Do you stock magnetic shower door seals for 8mm glass?

    Yes. We have a full range of high-strength magnetic shower door seals for 8mm glass.

  • Do you sell 90 degree or 45 degree magnetic seals for showers door?

    Yes. We stock both 90 degree magnetic shower door seals (for corner enclosures) and 45 degree magnetic seals.

  • Are your magnetic shower door seals universal?

    Mostly, yes. The standard UK installation gap for magnetic seals is 22mm. For straight doors: Your gap must be less than the size listed in our product specs. For 90° corner doors: The opposite applies. Your gap must be greater than the size listed.
