Separate cold and hot taps
Many small, early 20th-century sinks are equipped with these non-mixing taps. If you don’t mind the inconvenience and the taps are in good condition, keep them. If they’re in poor condi- tion, rusty, or need replating, replace them, either with a mix- ing tap or two separate reproduction taps. In the first instance, the extra hole can be filled with a plug. Or install a period-look soap dispenser in place of the old tap.
