Factory-Direct Since 1998
Since 1998, SIMBA has specialised in manufacturing shower door seals. As a factory-direct supplier with access to 9,000+ profiles, we help UK customers find the right replacement seal — including older, discontinued, and hard-to-match shapes.
Our Story
Built on Engineering Knowledge Since 1998
SIMBA was built on technical knowledge, not retail trends. Our founder, Mr. Liu, previously worked as a senior technical engineer for a leading seal manufacturer in the industry.
When that chapter came to an end, he started SIMBA to carry forward years of specialist experience in glass and shower door sealing profiles.
More than two decades later, that same engineering mindset still guides how we work — from profile design and material selection to manufacturing control and replacement support.
Why Choosing the Right Seal Matters
Many shower door seals look similar online, but small differences in shape, glass thickness, gap size, fin length and flexibility can decide whether a replacement fits properly.
The wrong seal may still leak, fail to grip the glass, or stop the door from closing correctly. That is why we focus on accurate profile information, clear sizing guidance, and practical support before you order.
Manufacturer-Made, Not Just Resold
Unlike general resellers, we work directly from our manufacturing supply chain. This gives us better control over profile design, material consistency, packaging, and replacement guidance.
For customers, this means clearer product information, more accurate profiles, and better support when a seal is difficult to identify.
Can’t Find Your Old Seal?Access to 9,000+ Profiles
Our UK website carries a focused range of commonly needed shower door seals. Through our factory range, we have access to over 9,000 seal profiles, including older, discontinued, and hard-to-match shapes.
If you cannot find the seal you need, send us a photo and we may be able to help identify a suitable replacement.
Tested for Real Bathroom Conditions
Our seals are tested against the conditions they may face in everyday use, storage, delivery, and installation.
- Light Exposure Test: Checks how the material performs under prolonged light exposure.
- Cold & Impact Test: Helps assess flexibility, durability, and product protection in colder conditions and during handling or delivery.
- 30,000-Cycle Use Test: Simulates repeated opening, closing, and daily shower door use.
Our Promise
Every SIMBA seal carries more than two decades of manufacturing knowledge, practical craftsmanship, and support from a team that understands how sealing profiles are made and how they should fit.
You are not just buying a replacement part. You are choosing a product designed to last, with guidance from people who understand the details.
