About OtterMax
A focused smart toilet OEM / ODM manufacturer — specialised in EN 1717 compliance and structural innovation
Engineering first, not volume first
OtterMax was founded in 2023 by Steven Tsao, an engineer with nearly a decade in smart toilet R&D. He saw that most manufacturers treated EN 1717 compliance as an afterthought — adding a check valve and calling it "certified."
OtterMax does the opposite: the anti‑backflow protection is integral to the ceramic casting and internal plumbing from day one of design. This approach is used by only 2–3 factories in China.
We are small and specialised — and that is intentional. It means fast communication, direct access to the engineering team, and a genuine partnership model where your product team works with the people who actually design and build the product.
What sets OtterMax apart
EN 1717 Designed‑In
Most Chinese factories use external backflow preventers. We integrate the air gap into the ceramic casting — fewer parts, fewer failures, full compliance verified by third‑party testing.
World‑First 3‑in‑1
UF heated seat + motorised auto‑lid + quick‑release — all in one wall‑hung product. A structural puzzle no competitor has solved. Two years of engineering, now in production across multiple European brands.
Three Purpose‑Built Platforms
ETW for EU wall‑hung toilets, ES for EU bidet seats, NS for North America. Each platform is designed for its market's voltage, certifications, toilet geometry, and installer expectations — not one product sold everywhere.
Platform Sharing Model
Shared internal architecture, customised exterior. You get proven reliability, lower MOQ, and faster time‑to‑market — without looking like everyone else. 2–4 months from design freeze to sample.
Built for compliance
Every platform ships with a full technical file — test reports, declarations of conformity, and material traceability documentation.
In‑house production
From injection moulding to final assembly — everything under one roof in Ningbo.
