Frequently Asked Questions

Is the V810S20 right for me? ▼
If you have premium 8mm or 10mm glass and are struggling with a significant floor gap of 17mm to 20mm, this is your solution. The V810S20 is our "Industrial Strength" specialist.

Not the right gap?
Will such a long fin stay on heavy 10mm glass? ▼
Yes. The V810S20 features a reinforced, extra-wide U-channel that uses high-tension friction to "lock" onto the glass. It won't slide or wobble, even on the heaviest luxury panels.
Why is the Free Threshold Strip (D510) included? ▼
In 17mm-20mm gaps, water spray has more room to escape. By using our 20mm seal together with the Free Threshold, you create a professional "Double-Dam" system. The seal deflects the spray, and the threshold blocks the surge, ensuring your bathroom stays 100% dry.

Watch the Double-Dam System in action
Will this handle high-pressure showers? ▼
Absolutely. The extended 20mm fin creates a flexible yet firm barrier. Our high-grade PVC ensures it stays upright and deflects water back into the tray efficiently.
What about corners and joins? ▼
Large gap seals require precision at the corners.

Expert Tip: Visit our guide "Bottom or Vertical Shower Seals: Which First?" to ensure your 20mm fin is trimmed for a perfect, leak-proof corner join.
Why Choose the SIMBA V810S20? (Click to expand)

8–10mm Glass Shower Door Bottom Seal – 20mm Fin | V810S20 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.
