Frequently Asked Questions

Is the V456S2023 right for me? +
This is our "Ultimate Reach" seal. If your shower door was installed unusually high, or if your floor has a significant slope leaving a gap of 20mm to 23mm, this is the only seal designed to bridge that distance.

Not the right size?
Do I really need the Free Threshold Strip (D510)? +
For extreme gaps, the answer is Yes. When a gap is over 20mm, water pressure at the bottom is at its highest. Using the 23mm seal in tandem with the D510 Threshold creates a professional-grade "Lock-Gate" system.
Will this handle high-pressure showers? +
Absolutely. The V456S2023 features a massive 23mm ultra-flex fin designed to deflect heavy water spray across extra-wide gaps.
Will it turn yellow over time? +
No. Our seals are crafted from Ultra-Clear, Anti-UV PVC. It is engineered to resist discolouration and maintain transparency even in sunlit bathrooms.
Is it easy to install without tools? +
Absolutely. This is a Snap-On seal. The rigid U-channel uses friction to grip the glass securely. No messy silicone or tape required.
What about where this seal meets my side (vertical) seal? +

Choosing the right fin length is key. Our guide answers your questions:

  • The Sizing Rule: Is 16mm right for your gap?
  • Installation Order: Vertical vs. bottom seal sequence.
  • Maintenance: How to inhibit black mould growth.

Care & Installation Tips

Ensure a better fit and longer-lasting clarity.

4–6mm Glass Shower Door Bottom Seal – 23mm Fin | V456S2023 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.
