How a basin and toilet are actually made — raw materials, firing and a walk through our Chaozhou floor. Start here to judge whether a supplier is the real factory.
A short walk through the Chaozhou floor where every basin and toilet is cast, fired at 1,250 °C, glazed and inspected — factory-direct, to 50+ countries.

Fifty degrees decides whether a basin cracks in winter or lasts a decade. Notes on the vitrification window and what changes at 1,200 °C.
Common ceramic defects, dimensional and functional checks, AQL sampling and the inspection workflow importers should run before shipment.
Build a repeatable toilet flush performance test plan before bulk production, covering setup, water use, waste removal, trap seal and golden-sample approval.
Identify sanitaryware glaze pinholes, crawling and crazing, then document, contain and investigate defects without assigning a cause from appearance alone.
