The Harbour 90mm matt black basket strainer waste includes matching round and rectangular overflow covers as well as the pipework connecting the overflow to the waste outlet. 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 with an overflow. If you also require a waste without an overflow then we do a matching Harbour 90mm matt black waste.
