Copper offers anti-bacterial properties so it requires little in the way of being disinfected and cleaned. Use a light soap to clean, or a microfiber cloth and wipe away dots of moisture to prevent marks on the copper.
Copper scratches heal over time. Enamel baths can scratch easily and once they are scratched, the only way to disguise it is to try and buff it or re-enamel the bath. Scratches made on a copper bath will disappear over time as copper has a living finish.
Copper baths age well. Unlike some bathroom trends – eg coloured tapware, copper baths will always stand the test of time and look good, even if they do darken over time.
