    Overview

    Engineered in Germany and constructed from SILGRANIT, this Blanco sink is stylish and sturdy in equal measure.

    SILGRANIT PuraDur consists of 80% granite, protecting the sink against scratches, bumps, and extreme heat. What’s more, the Hygiene + Plus formula creates an immunity against dirt and bacteria.

    With a double bowl configuration, you can keep your dishes separate from your utensils. You can make the most of this sink’s capacity thanks to a small 10mm radius between the wastes and the rear of the sink.
    Hygiene Plus

    Hygiene is paramount thanks to a patented formula that surfaces the sink, which hinders the growth of dirt and bacteria by an average of 98%.

    Silgranit

    The Silgranit material which is made of 80% granite makes this product seriously long-lasting, protecting against stains, heat, acid, scratches and potential fading.

    Very prone to stains and discoloration
    We purchased this sink a couple of years ago and after a few months of use we started to notice discoloration and now stains that would not come out even with bleach. We are very disappointed in this product given that it is advertised as "stain proof". Had we known we would have chosen another material. Would not recommend this product.
