Bathroom Hardware
manufacturers in China.

Taps, valves and fittings put this category on the plumbing chain, and the map follows. Taizhou holds the largest share by a wide margin, and the reason is Yuhuan — a county-level city under the same prefecture, appearing separately in this list, awarded China's Valve Capital by the China Hardware Products Association in 2003, with local production focused on brass and copper valves for water supply, HVAC, gas and fire protection. Huangyan district in the same prefecture adds injection-mould capacity, which matters for the plastic bodies, cartridges and trim that ship alongside brassware. The top three cities together hold 31% of the 327 in this category, spread across 82 cities, led by Taizhou, Hangzhou and Foshan.

Elsewhere in the list the documented local specialities point at other products — locks in Wenzhou, hand tools around Tangshan, door and window hardware in Foshan — so a large supplier count in those cities is not evidence of a bathroom hardware base, and those profiles need reading one by one. The checks that matter for this category are narrow: whether a company casts and machines brass itself or assembles bought-in bodies, whether plating is in-house, and which certification regime its products are built to. Those points separate a plant from a rebrander, and none of them can be read off a city name.
