A living finish is a promise that the fixture will not look new for long. That is now the selling point, and it changes the conversation at the specification stage.

For the plumber, the practical consequence is handling. Unlacquered surfaces record fingerprints, flux and tape residue permanently in the first weeks. Several manufacturers now ship installation guidance that reads like conservation advice.

Cost follows craft. Hand-formed basins and cast valve bodies carry lead times measured in months, which pushes coordination earlier into the build schedule.
