    Overview

    Carefully crafted in Germany, Blanco’s elegant, 52 litre Double Bowl Undermount Sink features straight line bowl geometry, effortlessly complementing a variety of kitchens, bathrooms and laundries.

    Uniting durability with style, this Silgranit sink is made of 80% granite, making it stain, heat, acid and scratch resistant. Made to last, it is easy-to-clean and non-fading. The even bowl configuration makes cleaning, stacking and organising contents easier than ever. A rear waste disposal system conveniently maximises under-sink storage space, whilst the integrated overflow regulates faster draining. And, with a raised tap landing, the tap is elevated from water, preventing the build-up of grime.

    Opt to maintain a consistent sink aesthetic, using Blanco’s compatible accessories.
    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%.

    Raised Tap Landing

    The raised tap landing prevents grime build-up around the tap, creating a more hygienic space.

    Integrated Overflow

    Enjoy a faster draining sink thanks to the integrated overflow.

    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.

    Questions & answers

    One customer has said that this product stains and another has said that the pipe sizes are hard to match is this true? Paul · 2025-05-16
    Hello Thank you for your question about this product. Granite composite sinks are very resistant to staining. With regular cleaning—about once a week—you can keep your sink looking as good as new. For daily cleaning, simply rinse the sink with water and wipe it down with a soft sponge or cloth to remove any food debris and soap residue. For weekly cleaning, you can use a mixture of baking soda and vinegar or dish soap. To do this, sprinkle baking soda over the sink's surface and gently scrub it with a soft sponge. Finally, rinse the sink with warm water. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500.
