⚠️ Pro-fit measurement tip
- Check the reach: This 18mm bulb is significantly larger than standard seals. Please ensure you have at least 14mm of clearance to allow the door to close comfortably.
- T-post check: Confirm your frame groove is 7mm wide. If you have a narrower 5mm or 6mm groove, the base will not fit.
Why choose BU003? (The problem solver) Tap to expand +
- Close the uncloseable: Is your shower door sagging or misaligned? Standard seals can't reach the frame, but our 18mm jumbo bulb bridges the widest gaps that others can't touch.
- Maximum water block: Designed for high-flow power showers where standard seals let "splash-back" escape through oversized gaps.
- Structural buffer: Acts as a heavy-duty shock absorber, preventing heavy glass doors from slamming against metal frames.
- Crystal clear & anti-mould: Despite its size, it remains discreet and transparent, infused with the same antimicrobial shield as our entire range.

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.
