How to Fit a Vertical Shower Door Seal
Installing a vertical shower door seal is straightforward and requires no specialist tools.
First, remove the old seal by gently pulling it away from the glass edge.
Clean the glass surface with warm soapy water to remove any residue or limescale deposits.
Push the new seal onto the glass edge, starting from the top and working downward, ensuring the rigid U-channel grips the glass firmly.
If the seal is longer than required, mark the desired length and trim with sharp scissors or a craft knife for a precise cut to size.
For magnetic seals, align both strips on opposing glass panels to confirm correct polarity before final fitting.
Finding the Perfect Vertical Shower Door Seal for Your Enclosure
Water leaking through the vertical gaps of your shower is often caused by more than just a worn strip. It can also be affected by the door type, glass alignment, closing angle and the size of the gap. Whether you are dealing with a 90-degree corner joint on a quadrant enclosure or an 180-degree inline glass-to-glass overlap on a sliding door, the right vertical shower door seal should help close the gap without obstructing the door’s motion.
At SIMBA, we understand that “universal” fixes rarely suit every UK bathroom, where hard water, daily use and constant moisture can all affect shower seals over time.
As a manufacturer-direct supplier with experience since 1998, we can help match many older and current vertical shower door seal profiles, including options for framed, frameless and glass-to-glass enclosures. Our vertical shower door seals are made from clear PVC and are quality checked before dispatch for profile, finish and overall condition.
