Check Before You Buy

Note: The slot may look slightly smaller in the drawing, but this helps the seal grip the glass securely once fitted. Please use the glass thickness listed above as your main guide.

This seal is suitable if:

  • Your glass is 10mm thick.
  • You need a bottom seal for a straight shower door or screen.
  • Your bottom gap is very small, around 0–3mm.
  • You need a strip up to 950mm long.
  • The rigid side fin can face inside the shower area.

Choose another seal if:

  • Your glass is not 10mm thick.
  • Your bottom gap is larger than 3mm.
  • Your door bottom is curved.
  • You need a seal longer than 950mm.
  • Your shower door has a metal frame or thick edge trim.

FAQ

1. What glass thickness does S10DTL fit?

It fits 10mm frameless shower glass.

2. What bottom gap is it suitable for?

It is best for very small bottom gaps, around 0–3mm.

3. Why does the slot look slightly smaller than 10mm?

The opening is made slightly tighter so the seal can grip the glass securely once fitted.

4. Which way should the rigid side fin face?

The rigid side fin should face inside the shower area.

5. Can I cut it to size?

Yes. The seal is 950mm long and can be trimmed shorter if required.

6. Is this suitable for curved shower doors?

No. S10DTL is designed for straight bottom edges only.

Suitable Applications

S10DTL is designed for 10mm frameless shower glass, especially thicker straight shower doors and screens where the glass sits close to the tray.

It works best where there is little or no bottom gap. The rigid side fin should face inside the shower area to help guide water back in.

This seal is supplied as one 950mm clear strip and can be cut shorter if required.

It is not suitable for thinner glass, curved door bottoms, framed doors, large bottom gaps, magnetic seals, guide rails or track seals.

10mm Glass Shower Door Bottom Seal with Side Fin Small Gap Seal S10DTL 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.
