Modern and warm for both new builds and renovations, the round nickel Sif is one of our biggest sellers. The matte brushed nickel finish gives off a warmer temperament compared to a traditional satin chrome or stainless finish. The warn nickel finish pairs especially well with wooden doors or timber features. This is common design both architects and designers will favour for a more contemporary design.
