Is the F810S20 the Right Choice for Your Shower?

The SIMBA 20mm 'F' Seal is our most popular choice for bathrooms that need a little 'extra reach'. If a standard 12mm seal leaves a frustrating gap, but a 35mm version feels too bulky, this 20mm mid-range profile is the professional's sweet spot.

01
Your Glass Thickness

Specifically designed to 'bite' onto 8mm, 9mm, or 10mm glass with a secure, glueless tension fit.

02
Your Gap Height

Ideally suited for clearances between 23mm and 38mm. The 20mm fin provides enough flexibility to seal tightly against the tray without buckling under pressure.

This model is a core component of our F shape shower door seals collection—engineered to solve the real-world plumbing challenges of UK homes.

Why Choose the SIMBA 20mm Mid-Profile 'F' Seal?

Forget 'one-size-fits-all' supermarket strips. The F810S20 is a targeted fix for specific gap issues.

+ The 'Goldilocks' Fit

Not too short, not too long. It bridges the gap where standard seals fail, without compromising the clean lines of your shower enclosure.

+ No Messy Silicone

The rigid U-channel clips onto the glass edge. It stays put during daily use but can be easily removed for a deep clean.

+ Stays Crystal Clear

Formulated with high-grade UV stabilisers to prevent that nasty 'yellowed' look that ruins the aesthetic of a clean bathroom.

+ Advanced Mould Resistance

Our PVC is infused with anti-fungal agents, protecting the seal’s flexible joints from black mould infestation.

If your shower screen is 4mm to 6mm, this seal will rattle. For a precise, rattle-free fit on slimline glass, please explore our [4mm - 6mm F Shape Seal Range]
