Throw away all other wastes. The Sillis UniWaste is the ultimate ALL IN ONE. No matter what the basin the UniWaste will fir it. 32mm or 40mm overflow non overflow thick basins thin basins exposed or hidden. It covers the lot. It even comes complete with a choice of two styes of pop up either standard or dome. Manufactured from solid brass with a highly polished chrome finish.
Loved the choice of two styles with either the dome or usual pop up.
It's universal size wise and as I didn't know if my basin had an overflow this was a great detail not needed. Watermark approved is an added bonus. The plumber hasn't installed it yet.
