Color bar
A color bar is a dedicated counter where stylists mix and prep hair color. It usually has organizers for tubes and bottles, a stain-resistant work surface and often a sink for cleanup, so color work moves off the styling stations.
Buy-Rite Beauty notes that most color bars with sinks need standard plumbing hookups, so place one where water lines and drains already run, ideally near the shampoo area. Put a hair trap on that sink too.
The salon floor plan maker has a 72 by 24 inch color bar and a back bar cabinet to pair with it. Plan bowls alongside it with how many shampoo bowls per stylist.
