The Harbour 90mm brushed brass basket strainer waste has a PVD coating which provides a more robust finish and protects your waste from surface damage caused by everyday use. PVD coating isn't just a metal layer that will start peeling away soon after it's installed. The actual PVD process deposits compound materials atom by atom which bond to the surface creating a much more durable and attractive finish. This Harbour waste is perfect to use with any of our Vellamo granite kitchen sinks but would look especially striking on a black or white one. It is also perfect for any of our Butler & Rose ceramic kitchen sinks that require a 90mm waste. This Harbour waste is for sinks or bowls without an overflow. If you require a waste with an overflow then we do a matching Harbour 90mm brushed brass waste with overflow covers.
