Shower Head Plating and Surface Finishing

Four finishing routes on a shower head

Chrome plating is the default. It gives the bright metal look most retail buyers expect on a hand shower, it wipes clean, and it is what the majority of the 96 catalog codes carry. Painting is used for matte black, white and color bodies, and it allows a soft matte surface that plating cannot give. Molded-in color from masterbatch has no coating at all, so nothing can chip or peel; it is the right route for kids and pet models and for transparent parts. Brushed nickel, gold, rose gold and gunmetal looks are the fourth route and are quoted per project.

The four routes are not interchangeable. A color that exists as masterbatch may not exist as a paint that passes the same handling, and a plated part and a painted part of the same model will not read as the same shade side by side. If a range has to match across finishes, say so at the RFQ stage rather than at the sample stage.

What decides whether a finish looks right

Molding quality comes first. Flash on a parting line, a sink mark opposite a rib, or a weld line across a visible face becomes more obvious under chrome, not less, because a bright finish reflects every change in the surface. That is why the finish specification starts on the molding page rather than at the plating stage.

Geometry comes second. Deep recesses, sharp internal corners and the inside of a slot receive less coverage than an open outer face, so a design with deep detail needs either a tolerance for the recess or a design change. Third comes the reference: a physical signed sample, kept by both sides, decides color and gloss. A Pantone number is a starting point, because the same number reads differently on a matte painted surface and on a bright plated one.

Testing a finish, and what a test does not promise

Salt spray testing is run on selected finishes, and the hours and the acceptance wording belong in the specification rather than in a marketing line. A salt spray result describes how a sample behaved in a defined test; it is not a warranty for a bathroom, and it does not cover damage from abrasive cleaners or acidic descalers. Adhesion and appearance are checked against the signed sample during the run.

ZHONGHE does not assert a certification for its finishes on this site. Test reports and certified options are arranged per project, and the scope is written into the quotation. If your market needs a specific report, name the standard and the test house in the RFQ so the cost and the lead time can be quoted with the product.

For end users, the practical guidance is in the cleaning guide linked below: warm water, a soft cloth and a mild detergent keep a plated or painted shower head looking right, while abrasive pads and strong descalers are what actually destroy a finish.

How to specify a finish in an RFQ

Name six things: the model, the finish route (plated, painted, molded-in color, brushed or PVD look), the color reference (Pantone number plus a physical sample where possible), the gloss level, which surfaces are cosmetic and which are hidden, and any test the finish has to pass with the standard and the acceptance criteria.

Ask in return for: a finished sample of the exact model and color, the lead time the finish adds to production, the MOQ per color rather than per order, and what the factory checks during the run. Note that a non-standard finish usually raises both the MOQ and the lead time, because a run has to be scheduled around it.
