Water and salt do not behave the same on every surface
A vertical face may shed water quickly while a flat top or horizontal ledge allows a droplet, salt deposit or cleaning residue to remain. Repeated wetting and drying can make that small area more vulnerable than the larger visible face.
This can affect mixer tops, towel-rail brackets, shower hinges, drain covers, shelf edges and cabinet hardware.
Geometry belongs in the specification
When comparing products for a coastal bathroom, look beyond the material label. Ask where water can sit, whether the surface can be wiped, whether a crevice traps residue and whether the finish-care instructions suit the location.
A sheltered, horizontal fitting near an open sea-facing window may need more attention than a similar product on a vertical internal wall.
Make maintenance possible
The fitting should be reachable without unsafe stretching, and its surface should be cleaned with the manufacturer-approved method. Do not allow salt to dry repeatedly and then attack the residue with an abrasive pad.
Small geometric decisions can change how long a premium finish looks premium.
