Frequently Asked Questions

Is the V456S16 right for me? +

If your shower door has a larger-than-average clearance, the V456S16 is specifically engineered to bridge the gap. Featuring an extended 16mm central deflector fin, this profile is designed for 4-6mm glass where standard seals fall short.

The structural design includes a reinforced junction at the base of the U-channel to ensure the longer fin remains stable. 👉 Exclusive Bonus: Each order includes a complimentary D510 Threshold Bar.

Not the right size?

How does the D510 Threshold Bar help? +

The D510 bar works in tandem with the 16mm fin to stop water dead. By installing the bar on your tray or floor, the fin overlaps it to create a secondary seal.

Expert Tip: Ensure the fin overlaps the bar by no more than 5mm to maintain a watertight seal without binding.

Will this handle high-pressure showers? +
Absolutely. The V456S16 features an extended 16mm soft-action fin designed to deflect heavy water spray across wider gaps.
Will it turn yellow over time? +
We use only Medical-Grade Virgin PVC. Unlike cheaper alternatives, our material is enriched with UV stabilisers and anti-fungal agents to keep the seal transparent and flexible.

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.

4-6mm Glass Bottom Seal | 16mm Fin V456S16 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.
