3/8 In. x 36 In. Frameless Shower Door Bottom Seal with Drip Rail

Keep water inside your shower enclosure with this 3/8-inch x 36-inch frameless shower door bottom seal. Designed for 8–10mm thick glass doors, this clear replacement seal slides securely onto the bottom edge of the glass without requiring adhesive.

The integrated 3/4-inch angled drip rail directs water back toward the shower interior, helping reduce leaks, puddles, and moisture around the shower floor. A flexible lower fin extends approximately 1/2 inch below the glass, helping close the gap between the shower door and threshold.

Made from transparent, water-resistant material, this shower door sweep blends naturally with frameless glass enclosures while providing dependable everyday protection. The seal measures 9/16 inch in channel height and can be trimmed to create a custom fit for shorter shower doors.

It is an ideal replacement for worn, cracked, yellowed, or missing shower door seals. Replacing the bottom sweep can help protect bathroom floors, baseboards, and nearby surfaces from repeated water exposure.
