Recommended Use for Bulb Seals

Best for vertical sides — not for the bottom!

Shower bulb seals are designed with a rounded top to create a soft, watertight closure on the vertical sides of shower doors.
Using them at the bottom can cause the bulb to trap water, creating a hard-to-clean groove that may collect dirt, mildew, or even mold over time.

👉 For bottom sealing, we recommend T-shape seals or drip rail seals designs instead — easier to clean and better at draining.

4 Key Differences Between SIMBA and Others

Packaging Details in SIMBA, Compared to other brands

1.Independent Packaging: Effectively prevents the seal strips from rubbing against each other during transportation, avoiding scratches, deformation, or damage. It also helps with batch storage, reducing the hassle of disorganized piling.

1.Bulk Packaging: May lead to damage to the seal strips during transportation and storage, potentially causing inconvenience during use and even impacting the end customer experience.

2.In-house mold department: SIMBA’s in-house mold department sets us apart from other brands. Our dedicated team ensures that molds are designed and manufactured within 24 hours of receiving your drawings. By maintaining full control over the mold creation process, SIMBA minimizes errors.

2.Other brands: lack an internal mold-making department and rely on outsourcing to third-party factories. This outsourcing often introduces delays, increases the risk of errors, and compromises the final product’s consistency.
