Check Before You Buy
The H810S15 is made for 8–10mm frameless glass where water is escaping through a vertical gap between two glass panels.
This seal is suitable if:
- Your glass is 8mm, 9mm or 10mm thick.
- The gap between the two glass panels is around 3mm to 13mm.
- Your shower door is hinged or pivot-style.
- The seal will be fitted to a straight, exposed glass edge.
- You need a side seal rather than a bottom seal.
- You need a seal up to 2000mm long.
Choose another seal if:
- Your glass is thinner than 8mm or thicker than 10mm.
- The gap is below 3mm or above 13mm.
- Your shower door is sliding, bi-fold, framed or curved.
- You need a seal for the bottom of the shower door.
- The gap is between glass and wall, glass and tray, or inside a shower track.
- A metal frame, trim or rail is blocking the glass edge.
- You need a magnetic seal, drip seal, threshold seal or sliding door seal.
If your shower has a different door type or gap position, please check our full range of vertical shower door seals before ordering.
Product Overview
The H810S15 is the longer-fin version for 8–10mm frameless shower glass. It is used on the vertical side of a hinged or pivot door, usually between the opening door and a fixed glass panel.
The rigid clear PVC U-channel pushes onto the glass edge, while the 15mm flexible fin reaches towards the opposite panel. This helps reduce water spray and leakage through side gaps of approximately 3–13mm.
The seal can usually be fitted to either the door panel or the fixed panel. Use the side where the soft fin sits most naturally across the gap when the door is closed.
After fitting, open and close the shower door slowly. Check that the fin does not catch, fold back the wrong way, or stop the door from closing properly.
No glue, screws or silicone are required for normal installation.
FAQ
Is H810S15 suitable for 8mm shower glass?
Yes. H810S15 is designed for frameless shower glass from 8mm to 10mm thick, including 8mm, 9mm and 10mm glass. It should not be used on 4–6mm glass, as the U-channel will not grip the thinner glass properly.
What size gap will the 15mm fin cover?
The 15mm soft fin is intended for vertical gaps of approximately 3–13mm between two glass panels. Measure the gap with the shower door fully closed. If the gap is only around 3–6mm, H810S8 may give a neater fit.
Can I use this seal on a sliding shower door?
No. H810S15 is not made for sliding shower door edges or sliding door overlaps. It is mainly for hinged or pivot frameless shower doors, where the seal sits vertically between two glass panels.
Can this seal be cut to a shorter length?
Yes. The seal is supplied in a 2000mm length and can be cut down to suit your shower door. Measure carefully before cutting, then check that the door still opens and closes smoothly once the seal is fitted.

Care & Installation Tips
Ensure a better fit and longer-lasting clarity.
✓ 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.
