Frequently Asked Questions

Will such a long 23mm fin make the door hard to open? ▼
Unlike cheap, stiff plastic, the V456S23CU uses a Tapered Fin Design. It is thick at the base for strength but thins out towards the tip. This allows the 23mm fin to glide effortlessly over your shower tray while maintaining a watertight "sweep."
Do you have a 23mm version for 8mm or 10mm glass? ▼
No. A 23mm fin on 10mm glass creates immense leverage that requires a specialized high-grip industrial U-channel. For thicker panels, please visit our [8mm-10mm Curved Range].
Water escapes from the hinge area—what should I do? ▼
While the 23mm seal stops water under the glass, it cannot block the hinge gap. We strongly recommend pairing this with our PV29 Threshold Bar.

Expert Tip: Use the V456S23CU for the door bottom and install the PV29 on the tray corner to stop water "creeping" through the hinge.

Why Choose the SIMBA V456S23CU? (Click to view details)

Curved Shower Seal for 4-6mm Glass Fin 23mm V456S23CU Installation Guide - Simba Anti-Mould Shower Seal

✓ DO’S

  • Direct Press: Fit by pressing directly onto the glass edge to protect the surface.
  • Deep Clean: Remove all UK hard-water limescale before installation.
  • Sharp Tools: Use garden pruners for a clean, professional finish.
  • Daily Rinse: Simply wash away soap suds after your shower.

✕ DON’TS

  • No Sliding: Never slide the seal along the glass; this risks scratching.
  • No Extreme Heat: Avoid water >70°C or hair dryers to prevent warping.
  • No Soapy Water: Do not use lubricants—they accelerate mould growth.
  • No Harsh Chemicals: Avoid bleach or acidic cleaners on the seal.
