Using this laundry butler sink is quite straightforward. First, make sure to choose the right waste type (32mm plug + waste or pop - up waste) as they are sold separately. When installing, measure the sink on - site before starting to build cabinetry or cut stone, and provide the sink to your cabinet maker and stone provider. During use, avoid dropping heavy or sharp objects into the sink to prevent cracking. For maintenance, clean the sink regularly with mild detergent and a soft cloth. Don't use abrasive cleaners as they may damage the ceramic surface.
