2-pack shower door bottom seal designed for 1/4 in. thick glass. The 23mm bottom strip covers a larger gap, helping keep water contained and the bathroom looking dry after showers. Made from clear vinyl, the material stays transparent and won’t discolor over time, while the soft bottom sweep lets the door glide with minimal resistance and without noise. The seal blocks water leakage by flexing to fill uneven gaps and can be trimmed to fit the gap between the door and the floor. The length is adjustable at 39 in. to accommodate most shower doors and works with a long drip rail to form a water barrier. Proper sizing is essential, so measure your glass thickness and door dimensions before installing. This seal is installed along the bottom edge of the door; you may remove the old seal and position the new strip under the door, then press up from the hinge side to engage with the glass. Even if the actual gap is smaller than expected, the flexible profile bends to block leakage. If needed, cut off the soft edge to customize fit and help seal the space against splashes. Together, the 2 seals help maintain enclosure cleanliness and reduce water on the bathroom floor.
