Frequently asked questions

Why choose a BLANCO SILGRANIT sink?

SILGRANIT is a patented granite composite sink material with superior strength and durability. With over three decades of material development, rapid advances in manufacturing technologies, and several BLANCO exclusive patents, SILGRANIT has become a global leader in coloured sinks. SILGRANIT sinks are heat, scratch and stain resistant and are proudly made in North America at our manufacturing facility in Toronto, Ontario.

What is SILGRANIT made of?

SILGRANIT is a patented granite composite material made of up to 80% natural granite. This finely ground granite is blended with a high-quality source of acrylic. This superior grade acrylic is made in-house under careful supervision and is blended with specially selected pigments which colors the material all the way through. The durability of SILGRANIT is the direct result of precise, strict protocols used during every step of production.

How durable is SILGRANIT?

SILGRANIT is extremely strong, making it impact and scratch resistant. If you drop a knife or metal utensil into your sink and it leaves a mark, don\'t worry. The metal has actually worn off onto the sink\'s surface. All you need is an abrasive sponge, some mild detergent or baking soda, and a bit of scrubbing effort to remove the mark.

Is it safe to handle food on SILGRANIT?

SILGRANIT has a defensive shield to protect you and your food from dirt and bacteria. Its patented Hygienic+Plus surface protection formula reduces bacteria growth by up to 98%. This makes SILGRANIT completely safe for contact with food.

Are the holes for faucets pre-drilled or already knocked out of the sink?

There is always one pre-drilled faucet hole in every drop-in SILGRANIT sink. However, there can be up to four additional knock-out holes available for soap dispensers, beverage faucets and other accessories. Extra knock-out holes are milled from the underside. You simply have to knock through the pre-milled holes.

What is the warranty on BLANCO SILGRANIT sinks?

All BLANCO sinks and faucets are supported by a Limited Lifetime Warranty. For full warranty details, visit our warranty page.
