STEIGNERShower Seals: which rubber seal keeps your shower watertight
“Shower seal” is the everyday name for the strips that keep a glass shower watertight. Most are not actually rubber — they are flexible PVC, TPE or silicone. Which shower seal you need depends on where the water is getting out.
For the door, screen, base, wall and corners of glass showers and enclosures.

What is a shower seal actually made of?
Few shower seals are traditional rubber. Four materials are common: PVC (cheap, firm, used on many magnetic and lip profiles), TPE (soft and flexible, good for wiper lips), silicone (heat- and UV-resistant, longer-lasting) and EPDM (true rubber, very weather-resistant). For sealing performance the shape and the right glass thickness matter more than the material.
Which shower seal goes where?
At the door: a magnetic profile (pivot door) or a lip seal (sliding or bi-fold door). At the base: a bottom seal with a wiper lip so nothing runs out under the glass. At the wall or glass edge: a U-channel or wall profile. On a walk-in, a water deflector guides run-off back into the tray.
Whatever the spot, the glass-thickness tolerance is what makes it work: a shower seal that is too big sits loose and drips; one that is too small will not push on.

Frequently asked questions
The 4 most common questions, answered.
Which shower seal do I need?+
It follows the leak point and door type: a magnetic seal for pivot doors, a lip seal for sliding or bi-fold doors, a bottom seal at the base, and a U-channel or water deflector at the wall and edge. Add the glass thickness (4/6/8/10 mm). Our configurator takes you to the right profile in under 90 seconds.
Are shower seals really rubber?+
Usually not. “Rubber seal” is a catch-all — most shower seals are made from PVC, TPE or silicone, and only some from true EPDM rubber. Silicone and EPDM are more UV- and heat-resistant and tend to last longer; PVC is cheaper and holds its shape well.
How long does a shower seal last?+
It depends on the material, water hardness and cleaning. Magnetic seals often last 5 to 8 years, lip seals 3 to 5, and base seals with daily water and pressure only 2 to 4. Once the lip goes hard, cracks or stains for good, it is time to replace it. Drying the seal after use extends its life.
Can I soften a hard old shower seal instead of replacing it?+
Only for a short while. Cleaning and lightly oiling a slightly stiff lip can help, but brittle or split material will not seal reliably again. Once a seal is porous, hard or warped, replacing it is the dependable fix — it costs a few pounds and takes minutes.
