Bottom Drip Seals | Plastic Extrusion Profiles

Bottom drip seals for shower doors help keep water inside the shower enclosure and off the bathroom floor. Known also as shower door sweeps, these seals have a small lip or drip edge that points toward the shower. Most shower doors use 3/8”, 1/4”, or 1/2” thick glass, and bottom drip seals are sized accordingly.

Commercial Glazing Seals for the Shower Door Industry

Vip Rubber and Plastic of La Habra, California (USA) makes drip seals for shower door bottoms but we do not keep these products in stock. Minimum order quantities apply, and we do not supply small amounts of material. Lead times may vary, so contact us to discuss your application if you are manufacturer.

Flex PVC, EPDM, and silicone are the three main materials for the drip seals that are installed along the bottoms of shower doors. Santoprene, a thermoplastic vulcanizate (TPV), is not a good choice for this squeegee-like application. With its high coefficient of friction, this TPE tends to drag water.

Flex PVC Bottom Drip Seals

Flex PVC is sometimes a good choice because it’s a low-cost option. Polyvinyl chloride (PVC), a versatile material, contains chemicals called plasticizers that impart rubber-like properties. PVC also resists chemicals and disinfectants, both of which are used to clean shower doors and enclosures.

EPDM Bottom Drip Seals

On the Vip website, bottom drip seals for shower doors are grouped with plastic extrusion profiles. However, EPDM rubber is also a common material of construction. EPDM is affordable, easy-to-maintain, durable, and resilient. It’s also water-resistant.

Silicone Bottom Drip Seals

Silicone rubber resists water and many chemicals. It also has one of the widest temperature ranges for elastomer. There are many different types of silicone, including materials with antimicrobial compounds that can easier cleaning and maintenance.

Installing Shower Door Bottom Drip Seals

Some shower doors have a large gap between the door and the floor. That’s why it’s important to measure the size of this space before ordering a seal or sweep. Vip Rubber and Plastic also offers co-extruded shower door bottom drip seals that are designed to accommodate 1/4” glass.
