Those looking to upgrade their food-preparation spaces may be interested in purchasing granite countertops for their kitchen sink areas.That is the suggestion of interior design expert Caroline Castrucci, who noted that the material remains a popular choice because it is easy to maintain, Canada.com reports. Granite is so easy to keep clean, to look after and to look at, she remarked, adding that the substance has been implemented in her own cooking zones. According to Ms Castrucci, granite was used on both of her kitchen islands in conjunction with cherry hardware to give visual appeal. New appliances can also add to the look of a kitchen, she commented, with coffee makers and espresso machines highlighted as particularly desirable. Editorial director of Remodeling magazine recently advised Boston Globe readers to buy granite work surfaces if they intend to sell their property in the near future.It might be the conservative option, but this is often necessary, he said.
