Frequently Asked Questions

Will this stay on a heavy 10mm glass door? ▼
Yes. The V810S20CU is engineered for heavy, premium doors. It features an extra-deep 10mm+ Deep-U Channel grip that ensures the curved seal stays aligned without twisting.
Does a longer fin lead to more hinge leaks? ▼
Large gaps increase water pressure at corners. For luxury doors, always pair this with our PV29 Threshold. While the 20mm fin seals the bottom, the PV29 blocks the hinge gap.
Is this seal hard to clean? ▼
Definitely not. Despite its heavy-duty size, the non-porous PVC resists limescale. A quick wipe with soapy water keeps it crystal clear.
Can I use this on 6mm glass with a large gap? ▼
We don't recommend it. Using an 8-10mm seal on 6mm glass leaves a loose channel. Instead, use our [Extra-Long 4-6mm Curved Seals] specifically designed for that glass thickness.
Why Choose the SIMBA V810S20CU? (Click to expand)

Curved Shower Seal for 8-10mm Heavy-Duty Glass Fin 20mm V810S20CU 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.
